SDIC Power: China's Second River Empire

I. Cold Open & Roadmap

In the third week of August 2022, the assembly lines at 富士康 Foxconn's Chengdu campus — the plant that builds iPads for Apple — went dark. So did トヨタ Toyota's Sichuan joint venture, and so did 宁德时代 CATL's battery works in Yibin. The Sichuan provincial government had done something almost unheard of in modern Chinese industrial policy: it ordered industrial power users across the province to simply stop, from August 15 through August 20, and then extended the order.¹ The reason was not a grid failure or a coal shortage. It was that the rain had not come.

Sichuan is the most hydro-dependent large province on Earth. Roughly four-fifths of its electricity comes from rivers. In the summer of 2022, average rainfall across the province fell by about 51% against the historical norm at exactly the moment a record heatwave sent air-conditioning load to an all-time high. Daily hydropower output halved. Reservoir storage collapsed to around 1.2 billion cubic metres, roughly 4 billion below the prior year.² The province that exports power to Shanghai found itself rationing power to its own factories.

Somewhere in the middle of that story sits a company most investors outside China have never heard of. 国投电力 SDIC Power Holdings — Shanghai ticker 600886 — controls the cascade of dams on the 雅砻江 Yalong River, a tributary of the Yangtze that runs off the eastern edge of the Tibetan Plateau through Ganzi and Liangshan prefectures before joining the Jinsha. It is the third-largest hydropower base among China's thirteen designated major basins, with roughly 30 GW of exploitable capacity, and SDIC Power's joint venture is the sole entity licensed to develop the main stem.³ After the Three Gorges cascade on the Yangtze mainstem, it is arguably the most valuable river system in commercial hands anywhere.

That is the seductive part of the story. Here is the complicating part. As of the end of 2025, hydropower accounted for only about 45% of SDIC Power's installed capacity. The company also ran 13.1 GW of coal-fired and gas-fired plant in Fujian, Tianjin, Guangxi and Xinjiang, plus a fast-growing 11.8 GW of wind and solar.³ Its balance sheet carried RMB 189.8 billion of liabilities against RMB 313.6 billion of assets.⁴ It has gone back to capital markets — bonds, a London GDR, a RMB 7 billion equity placement — repeatedly over the last five years, while simultaneously committing to pay out at least 55% of earnings as dividends.

There is one more wrinkle, and it is the sort of detail that reframes a whole story once you notice it. The second-largest shareholder in SDIC Power is 长江电力 China Yangtze Power — the very company investors use as the benchmark against which SDIC Power is judged and found smaller.⁴ The little sibling is partly owned by the big one.

So the question this episode keeps circling is a simple one, and it is the question every investor who has looked at this stock eventually asks. Is 国投电力 SDIC Power a cheaper way to own the same royalty-like hydro cash flows that make 长江电力 China Yangtze Power the blue-chip of the Chinese utility sector? Or is it a structurally more levered, more thermal-exposed, more hydrologically concentrated version of that trade — one where the discount to Yangtze Power exists for reasons, not by oversight?

The answer, as usual, is that both descriptions are partly true, and the interesting work is figuring out which parts.

The route there runs through four questions. How did a company that began life as a chemical-fibre shell end up holding an exclusive licence to one of the best rivers in the world? What does the river actually earn, and how much of that reaches an outside shareholder? Why does a business generating RMB 31.6 billion of operating cash flow keep going back to the market for equity?⁴ And what happens to all of it when China finishes dismantling the fixed-tariff regime that has underwritten Chinese generation economics for thirty years?

Start with the shell.

II. Origins: Built by the State, For the State

There is no founder in this story. No garage, no napkin sketch, no moment of solitary conviction. What there is instead is a regulatory approval letter, a shell company, and a date.

Ticker 600886 first traded on January 18, 1996, and it did not belong to a power company at all. It belonged to 湖北兴化 Hubei Xinghua, a chemical fibre producer whose controlling shareholder was a Sinopec petrochemical works in Jingmen.⁵ For six years it did what small listed Chinese industrials did in the 1990s: paid dividends, issued bonus shares, ran a rights issue, and went nowhere in particular.

Then, on April 28, 2002, two agreements were signed on the same day. In one, Hubei Xinghua agreed to swap its entire operating asset base for equity assets held by 国家开发投资集团 SDIC Group — State Development & Investment Corporation, one of the original central state-owned investment holding conglomerates created in the 1990s.

In the other, Sinopec agreed to transfer its entire shareholding to SDIC. Both became effective on September 30, 2002, and the assets were delivered the same day.⁵ The listing survived; everything inside it was replaced. The company itself still describes this straightforwardly as a backdoor listing — 借壳上市 — and dates its capital-markets history from it.⁵

That origin matters more than it sounds, because it defines the company's entire operating logic. SDIC Power was not built by entrepreneurs who found a river. It was designated, from the outset, as SDIC Group's sole listed capital-operations platform for the power business. Its job was to be the vehicle into which the parent injected generation assets over time. The company says this about itself in its own filings, plainly and without embarrassment: through asset injections, it obtained 雅砻江水电 Yalong Hydro and 国投大朝山 SDIC Dachaoshan, and that is how it grew large quickly.⁶

The early portfolio was the unglamorous kind. Coal-fired plants scattered across provinces — Tianjin, Fujian, Guangxi, later Xinjiang — bought or built because the state needed generation capacity and SDIC Group had the balance sheet to fund it. These were commodity businesses in the purest sense: buy coal at a price you do not set, sell electricity at a tariff you do not set, and hope the spread holds. They are still there today, still doing exactly that, and most equity investors who own the stock would prefer to look past them.

The transformational event came in 2009. In March of that year, the company — then trading under the name 国投华靖电力控股 SDIC Huajing Power Holdings — agreed to issue 940,472,766 new shares to SDIC Group at RMB 8.18 apiece in exchange for 100% of SDIC Power Co. Ltd., the parent's unlisted generation vehicle.

The board approved it on March 2, shareholders on June 24, and the CSRC cleared both the issuance and a waiver of the mandatory tender offer that would otherwise have been triggered. When it closed, total share capital had risen to 1.995 billion shares and SDIC Group held 70.54%.⁵

Inside that transaction was the asset that would define the company for the next two decades: 二滩水电 Ertan Hydropower, the entity that became Yalong River Hydropower Development Co., carrying the sole development licence for the entire Yalong main stem.⁵⁶ Ertan itself had been operating since the late 1990s — a 3.3 GW anchor station near the river's mouth, financed in part by the World Bank.⁵ But a single dam is a power plant. A licence to develop an entire river, in sequence, over forty years, is something else entirely.

Note the mechanics, because they recur. The parent was paid in stock. The listed company's share count roughly doubled. Minority holders got a river and a dilution, simultaneously — a pattern that looks familiar again by 2025.

This is the structural fact that shapes everything downstream, and it cuts both ways. On the favourable side: SDIC Power did not have to compete for the Yalong. It did not bid against Huaneng or the State Power Investment Corporation for the basin. The resource was allocated administratively, to a central SOE, at the state's discretion.

Nobody overpaid, because there was no auction. On the unfavourable side: the same mechanism that granted the resource also means the company's strategic direction is not set by its board in isolation. Capital gets deployed where the parent and the state need it deployed — which has meant a two-decade construction programme that has never really stopped.

One more piece of the ownership picture was added in October 2020, when SDIC Power listed global depositary receipts in London under the Shanghai–London Stock Connect scheme, raising roughly US$200.6 million at US$12.27 per GDR and becoming only the fourth Chinese issuer to use the channel.⁷ The proceeds were modest relative to the company's capital needs.

The signalling value was the point: a state generator putting itself in front of international institutional investors, with the disclosure obligations that come with it. The annual report SDIC Power files with the London Stock Exchange in English every April is, for a non-Chinese-reading analyst, by some distance the most useful document the company produces.

But the London listing is a footnote. Everything that actually matters about this stock starts with one river in southwest China, and with a decision to spend two decades and well over RMB 100 billion damming it.

III. The Yalong River Bet: Building an Irreplaceable Asset (2000s–2021)

To understand why hydropower engineers get emotional about the 雅砻江 Yalong River, you have to think about what a hydroelectric dam actually sells. It sells the product of two numbers: how much water falls past the turbine, and how far it falls. Flow times head. Most rivers are generous with one and stingy with the other. A big lowland river has enormous flow but almost no gradient — you can dam it, but you have to flood an enormous area to build up any head, drowning towns and farmland in the process.

The Yalong is the rare river that is generous with both. It drops off the Tibetan Plateau through deep, narrow gorges while carrying the runoff of a catchment the size of a mid-sized European country. Take just the lower reach, from Kala down to the confluence at Jiangkou: 412 kilometres of river with a natural drop of 930 metres, geologically stable, and — in the phrase that does the most work in every engineering document about this basin — with small inundation loss.⁵ Because the valleys are steep and sparsely populated, the reservoirs are deep rather than wide.

Here is what "small inundation loss" means in human terms, and it is the single most underappreciated fact about this asset. Across eight Yalong projects — Guandi, Jinping I and II, Tongzilin, Lianghekou, Yangfanggou, Kala and Mengdigou — total resettlement came to roughly 25,198 people.⁵ Guandi displaced 3,266, relocated by September 2012. Jinping I and II together displaced 10,454, completed by June 2012. Lianghekou, the largest reservoir on the river, displaced 7,569.⁵ For context, mainstem Yangtze megaprojects have displaced populations orders of magnitude larger, and resettlement is routinely the binding political and financial constraint on Chinese hydropower development.

The Yalong largely escapes it. That is not a footnote to the investment case — it is a substantial part of why this basin could be built at all, on schedule, without the decades-long delays that have stalled comparable projects elsewhere in the world.

The corporate structure that owns this is worth pausing on, because it is unusual and it matters. 雅砻江流域水电开发有限公司 Yalong River Hydropower Development Company is not wholly owned. SDIC Power holds 52%; 川投能源 Sichuan Chuantou Energy, the listed vehicle of the Sichuan provincial investment group, holds 48%.³ This is central-SOE capital married to provincial-SOE capital, and it is not an accident.

The central government controls the development licence and the technical capability; the province controls the land, the resettlement politics, and a claim on the resource that flows through its territory. The 52/48 split is the negotiated price of that alignment.

For investors the consequence is specific. SDIC Power consolidates Yalong Hydro in full — all of its revenue, all of its assets, all of its debt appear on SDIC Power's statements — but 48% of the profit is then stripped out as minority interest. In 2025, SDIC Power's consolidated net income from continuing operations was RMB 13.5 billion, of which only RMB 7.4 billion was attributable to SDIC Power's own shareholders.[^8] Nearly the entire gap is Chuantou Energy's share of the river. Anyone comparing SDIC Power's headline consolidated numbers to a wholly-owned peer's without adjusting for this will get the wrong answer.

The buildout arc runs across roughly a quarter-century, and the river was developed from the bottom up — downstream first, where the geology was simplest and the transmission shortest, then progressively higher into the mountains.

Ertan came first, 3.3 GW at the downstream end. Then the flagship 锦屏 Jinping complex: Jinping I at 3.6 GW behind a double-curvature arch dam among the tallest in the world, and Jinping II at 4.8 GW, which does something genuinely ingenious. Rather than build a tall dam, Jinping II bores tunnels straight through a mountain to cut across a long bend in the river, harvesting the drop across the shortcut. The dam is modest; the head is enormous. Then 官地 Guandi at 2.4 GW and 桐子林 Tongzilin at 0.6 GW completed the lower cascade — five stations, 14.7 GW.⁵

The middle reach, still being built, is a seven-station scheme totalling 11.87 GW, with Lianghekou designated the 龙头 — the "dragon head," the controlling reservoir at the top.⁵ That designation is not poetic. It is a dispatch hierarchy.

And then came 2021, the year everything on the Yalong changed twice. On September 29, 2021, 两河口 Lianghekou entered commercial operation — 3 GW of capacity behind a 295-metre earth-rock dam, the highest of its type in China and among the highest in the world, at the highest altitude of any megawatt-scale station in the country, designed for roughly 11 TWh a year.⁸ Two and a half weeks later, on October 16, all four units at 杨房沟 Yangfanggou went commercial: 1.5 GW behind a 155-metre concrete arch dam, and China's first million-kilowatt-class hydropower project delivered under an EPC contracting model rather than the traditional owner-managed construction approach.⁹¹⁰

Yangfanggou was the engineering milestone. Lianghekou was the economic one, and the distinction is worth explaining carefully, because it is the single most important thing to understand about this company's earnings power.

Most hydropower stations are what engineers call run-of-river: water arrives, water passes through the turbines, electricity gets made. Output tracks rainfall almost one-for-one, which means it peaks in the wet season, when power is cheap and demand is moderate, and collapses in the dry season, when power is scarce and valuable. A regulating reservoir breaks that link. Lianghekou sits high in the cascade with enough storage to hold back a substantial share of the wet-season flood and release it through the dry months — and crucially, every drop it releases then passes through every downstream station on the river. One reservoir at the top lifts the utilisation and the seasonal value of the entire cascade below it. Think of it as a battery whose capacity is measured in cubic kilometres.

Combined with Ertan and Jinping I, the basin's three regulating reservoirs now provide roughly 14.8 billion cubic metres of storage capacity.¹¹ That number is the physical basis for essentially every claim SDIC Power makes about smoothing output, integrating renewables, and defending against drought.

Does the claim hold? Partly, and the evidence is mixed rather than triumphant. In 2022 — a genuinely dry year on the Yalong — the company's hydropower on-grid volume nonetheless rose 12.37%, and Yalong Hydro's net profit rose 15.73% to RMB 7.36 billion, because the two new stations and improved cascade dispatch more than offset weak inflows.¹² That is regulation working.

But in 2025, with inflows again below normal, Yalong's generation fell and the group's hydro utilisation hours dropped 282 hours to 4,604.³ Yalong Hydro's profit still rose 11.59% to RMB 9.22 billion — but the report attributes that to lower maintenance costs, lower finance expenses and lower taxes, not to hydrology.³ Reservoir regulation reduced the amplitude of the swing. It did not remove it.

Now the comparison everyone reaches for. 长江电力 China Yangtze Power owns the Three Gorges, Gezhouba, Xiluodu, Xiangjiaba, Wudongde and Baihetan stations on the Yangtze mainstem — 71.8 GW of hydropower at the end of 2025, against SDIC Power's 21.3 GW, and net profit of RMB 34.5 billion against SDIC Power's RMB 7.4 billion.¹³³ In market value the gap is wider still: roughly RMB 110 billion for SDIC Power in mid-August 2026, against something over six times that for Yangtze Power.[^15] The Yalong is a great river. It is not the Yangtze mainstem, and the market has never confused the two.

One honest caveat on capital discipline, since it is the question a diligent investor would ask next: there is no clean way to benchmark whether SDIC Power "overpaid" for any of this. Almost all of the deployment was internal greenfield construction and JV capital calls, not open-market M&A. There is no transaction price to compare against what 华能 Huaneng paid for comparable positions on the Lancang cascade, because neither company bought its river — both were assigned them.

What can be assessed is execution and financing cost, and those are examined in detail further on. But an investor looking for a "paid 8x versus peers at 11x" scorecard on the Yalong buildout should be told plainly that the data does not exist.

What does exist is the operating business those dams now support — and the segment economics inside it are stranger and more revealing than the headline numbers suggest.

IV. The Core Business Today: What Actually Drives the Stock

Here is a fact that, once you see it, reorganises how you read every SDIC Power financial statement.

In 2025, the company's Southwest China region — which is functionally the Yalong cascade plus a handful of Sichuan and Yunnan assets — produced RMB 27.5 billion of principal-business revenue at a gross margin of 58.6%. The group as a whole produced RMB 52.6 billion at 41.0%.³ So roughly half the revenue carried a margin nearly eighteen points above the corporate average, and by implication the other half carried a margin far below it. Two entirely different businesses are stapled together inside one ticker, and they behave nothing alike.

The 2025 results themselves look, at first glance, like a bad year that somehow ended well. Revenue fell 8.31% to RMB 53.0 billion. Total on-grid electricity fell 8.06% to 154.2 TWh. Average utilisation hours across the fleet dropped 502 hours to 3,651.³ And yet net profit attributable to shareholders rose 11.30% to RMB 7.39 billion, earnings per share rose 5.73% to RMB 0.9166, and operating cash flow jumped 28.03% to RMB 31.6 billion.⁴¹⁴

How does a generator sell 8% less electricity and earn 11% more money? Three mechanisms, and each says something different about the business.

First, coal got cheaper. The cost of principal operations fell 13.78% — faster than revenue — as coal prices declined through the year, and the electricity gross margin expanded 4.11 percentage points.³ Every regional commentary in the annual report tells the same story: North China revenue down 10.17% but gross margin up 10.20 points; East China revenue down 19.43% with margin up 7.00 points.³ That is not operational brilliance. That is a commodity input falling.

Second, financing costs collapsed. Financial expenses fell 21.25% to RMB 2.69 billion from RMB 3.41 billion, and interest coverage improved to 4.12 times.⁴¹⁵ For a company whose interest bill has historically consumed a large share of pre-tax profit, a RMB 725 million reduction is worth more than a full percentage point of margin.

Third — and this is the uncomfortable one — the mix shifted toward hydro even as hydro volumes fell, because thermal volumes fell much harder. Thermal utilisation dropped 722 hours, more than double the hydro decline, squeezed out by nuclear and renewables in Fujian and by new renewable capacity in Guangxi and Hebei.³ Losing low-margin coal volume flatters the blended margin. It is not the same thing as growth.

The capacity mix explains why hydro punches so far above its weight. At the end of 2025 the company operated 46.9 GW: 21.3 GW hydro, 13.1 GW thermal, 4.1 GW wind, 7.7 GW solar and 0.7 GW of storage, with clean energy at 72.12% of the total.³ Hydro is under half of installed capacity and generates roughly two-thirds of attributable profit. The reason is cost structure. A hydro station's fuel is free.

Once the dam is built, the cost base is depreciation, a modest maintenance crew, water-resource fees and interest — all of which are fixed or near-fixed. Every incremental kilowatt-hour drops almost entirely to gross profit. A coal plant, by contrast, spends most of its revenue on coal. In 2025 SDIC Power's coal units burned 301.14 grams of standard coal per kilowatt-hour supplied, up 4.43 grams year on year as units ran more flexibly and less efficiently.³

The trade is stark and worth stating in one line: hydropower is a wonderful business with an input the company cannot control, and thermal power is a mediocre business with an input the company cannot control either. One of them at least has a fifty-year asset life and no fuel bill.

One more structural feature belongs here, because it quietly shapes how the company earns money. SDIC Power runs nine electricity sales subsidiaries trading power in more than a dozen provinces and municipalities, from Beijing and Shanghai to Guangdong, Gansu and Sichuan, and sold 36.5 TWh through that channel in 2025, up 7.54%.³ This is not a trivial add-on. As China's power market liberalises, the ability to sit on both sides — generating electrons and separately contracting to sell them to end users — becomes a hedge against the very tariff volatility that liberalisation creates.

It is one of the few places where the company has agency over price rather than just volume. It is also, so far, small relative to the 154 TWh the group puts on the grid.

Where does this leave SDIC Power competitively? The Chinese generation sector is dominated by a handful of central SOE groups. 长江电力 China Yangtze Power is the sector's blue-chip — bigger, purer, less levered, and increasingly run as a distribution machine, with a 71% payout in 2025 and a stated commitment to at least 70% of net profit annually from 2026 through 2030.¹³ 华能国际 Huaneng Power International and 华电国际 Huadian Power International are the thermal-heavy diversified giants. 国家电投 SPIC is the nuclear-and-renewables-heavy one. 龙源电力 China Longyuan Power is the wind pure-play.

Against that field, SDIC Power occupies a specific and somewhat awkward middle: too hydro-tilted to be valued as a thermal generator, too thermal-exposed and too levered to be valued as a hydro royalty.

Run the Five Forces and the picture sharpens. Barriers to entry are as close to absolute as commercial life offers — you cannot build a new Yalong River, the thirteen major basins are already allocated among state groups, and the licence to develop this one belongs to a single JV. Supplier power is low: turbine manufacturers compete, and an SOE with SDIC Group behind it borrows at rates that would make a private developer weep, with 2026 domestic bonds priced as low as 1.90%.⁴ Substitutes are the live threat — solar at current costs is a genuine competitor for daytime energy, which is precisely why the company is building so much of it. Rivalry among incumbents is muted by geography; dams do not compete with each other for customers.

Substitutes deserve one more sentence, because the threat is subtler than it first appears. Solar does not compete with hydro for the same hour of the day in the same way a rival dam would. It competes for the middle of the day, in the wet season, in the same province — precisely when Sichuan's rivers are already running full and prices are already at their lowest.

The overlap is at the worst point of the curve. That is why the company's answer has been to build the solar itself and pair it with storage, rather than to compete against it.

Buyer power is where the story is changing, and it is the most important forward risk in this section. Historically, Chinese generators sold to provincial grid companies at administered feed-in tariffs. That world is dissolving. In 2025, 45.25% of SDIC Power's on-grid volume — 69.8 TWh of it — was sold through market trading, up 3.61 percentage points in a single year.³ The company's own risk disclosure is unusually candid: provincial spot markets now have "nearly full coverage," gaps between spot and medium-to-long-term prices have already affected earnings in some regions, and market rules are still being rewritten mid-game.³ Roughly half the revenue line has migrated from administered pricing to negotiated pricing in under a decade, and the company has never operated a full drought-to-flood hydrological cycle under the new regime.

On the 7 Powers framework, the honest reading is that SDIC Power has one real power and it is a Cornered Resource: exclusive rights to develop the main stem of a basin with roughly 30 GW of exploitable hydropower, of which 19.2 GW was operating at end-2025 and 3.72 GW more was approved or under construction.³ That is not marketing. A competitor with unlimited capital cannot replicate it, because the licence is not for sale and the river is not fungible.

But it is worth testing the claim rather than accepting it. A cornered resource creates durable excess returns only if it also confers pricing power, and here the evidence is weaker. SDIC Power does not set the price of Sichuan electricity; the grid and, increasingly, the spot market do. Its average on-grid tariff was RMB 0.354 per kWh in the first quarter of 2026, down slightly year on year.¹⁶ The resource guarantees a low-cost position and an extremely long asset life.

It does not guarantee that the company captures the value — the state, the grid, and the 48% minority partner all have claims on it. Cornered resource, yes. Pricing power, no. Those are different things, and conflating them is the most common error in the bull case for this stock.

Which brings the story to the other half of the company — the half nobody buys the stock for, and the half that decides whether a bad water year is survivable.

V. The Other Half: Thermal Power as Diversifier and Drag

In March 2022, 华能国际 Huaneng Power International reported a net loss of RMB 10.26 billion for the prior year. Its revenue had grown 20.75%. Its average coal purchase price had grown 60.85%, to RMB 770.67 per tonne, while the electricity price it received had risen 4.41%.¹⁷ That is not a bad quarter. That is an entire business model inverting.

Huaneng was not alone. 大唐发电 Datang Power guided to losses of RMB 9.0–10.8 billion, 华电国际 Huadian International to RMB 4.5–5.3 billion, 国电电力 Guodian Power to RMB 1.6–2.3 billion.¹⁷ The CECI 5,500-kcal thermal coal index averaged RMB 1,044 per tonne across 2021, up 81.3%, driven by domestic supply restrictions, import limits and a demand rebound.¹⁷ Chinese coal generators were being forced to buy fuel at market prices and sell electricity at administered prices, and the arithmetic simply did not work.

SDIC Power was not spared. Its attributable net profit fell to RMB 2.46 billion in 2021 from RMB 5.52 billion in 2020 — a 55% collapse in a year when its hydropower fleet was actually growing.[^8] The river held up. The coal plants did not, and they dragged the whole company down with them. It is the clearest natural experiment available on what thermal exposure costs this business at the tail.

The policy response arrived in October 2021, when regulators widened the permitted floating range on coal-fired on-grid tariffs to plus or minus 20% and lifted price ceilings for high-energy-consuming users.¹⁷ By the first half of 2022 the effect was visible in SDIC Power's numbers: average on-grid tariff rose 8% year on year to RMB 0.359 per kWh, revenue rose 17.58%, and attributable net profit edged up 0.30% to RMB 2.35 billion.⁶ Stability, but only just.

Look one level down and the individual thermal subsidiaries were still bleeding — 国投湄洲湾 SDIC Meizhouwan swung to a RMB 166 million loss, 国投津能 SDIC Jinneng to a RMB 290 million loss, both attributed explicitly to higher unit coal costs.⁶ The tariff band cushioned the fall. It did not restore profitability. The recovery in the thermal segment since has come far more from coal prices normalising than from any structural change in what these plants can charge.

So what is thermal actually for? The company's own framing, repeated across the 2025 annual report and the May 2026 results briefing, is that coal power has shifted from a baseload source to a "supportive and regulatory" one, and that it functions as the 保供底盘 — the supply-security chassis.³¹⁸ Read plainly, that means: these plants exist to be there when the water is not, and to keep the lights on during peak load, and the company is compensated partly through capacity payments and ancillary-service revenue rather than pure energy sales.

Is that a strategy or a rationalisation? The capital allocation gives a more honest answer than the language does. SDIC Power is not exiting thermal. It commissioned Unit 5 at Huaxia Power in 2025, began construction on Units 5 and 6 at Meizhouwan, and advanced Units 3 and 4 at Qinzhou Second Power plus two gas turbines at Zhoushan.³ Its thermal fleet is concentrated in economically developed coastal provinces, and 61.35% of thermal capacity sits in million-kilowatt-class units — the newest, most efficient, most flexible tier.³ It has also secured new renewable project approvals explicitly on the strength of its coal-supply-security contribution, an integrated "coal power plus new energy" model that trades one for the other.³

That is not the behaviour of a company that would exit coal if it could. It is the behaviour of a company for which coal capacity is the entry ticket to renewable allocations, and where the SOE mandate to guarantee supply is a genuine constraint on portfolio choice, not a talking point.

It is worth being precise about the mechanism, because it is easy to miss. In the current Chinese planning regime, the right to develop large renewable bases is allocated, not auctioned to the highest bidder. Contribution to supply security is one of the criteria. SDIC Power states directly in its 2025 report that it secured approvals for a number of new energy projects on the strength of its coal-power supply-security contribution, and that an integrated coal-power-plus-new-energy development model has been substantially implemented.³ Read as an investor rather than as a policy reader, that says: the coal fleet is a licence-generating asset. Its accounting return is only part of its economic function.

The corollary is uncomfortable for anyone hoping for a clean hydro pure-play. If coal capacity buys renewable allocations, then divesting coal would reduce future growth options, not just eliminate a low-margin segment. Investors waiting for SDIC Power to become a Yangtze Power lookalike by shedding thermal are waiting for something the incentive structure actively discourages.

For investors, the practical implication is a reframing. The bull case usually treats thermal as a drag to be netted out of the hydro valuation. The more accurate framing is that thermal is a partial hedge whose correlation flips at exactly the wrong moment — it does earn money in dry years when hydro output falls and power prices rise, but it also lost RMB 3 billion of group profit in 2021, a year when nothing was wrong with the rain. Investors should not underwrite it as ballast without acknowledging that it has its own independent way of going badly.

And the thing coal power is currently buying — the renewable allocations — is where management says the next decade of growth lives.

VI. The New Energy Build-Out: Real Optionality or Dilutive Growth?

At roughly 4,000 metres above sea level in Sichuan's Garzê prefecture, on mountainsides where the air holds about 60% of the oxygen it does at the coast, sits the 柯拉 Kela solar station — and, newly, the 查布朗 Chabulang station, described by SDIC Group as China's largest ultra-high-altitude mountain photovoltaic project, brought to full capacity during 2025 alongside the grid connection of the 索绒 Suorong station.³ Panels at that altitude are unusually productive: thin, cold, clear air means high irradiance and good conversion efficiency. They are also a logistical ordeal to build and maintain, which is why almost nobody had done it at scale before.

The reason SDIC Power is doing it is not the sunshine. It is the reservoirs sitting a few dozen kilometres downhill.

This is the 水风光一体化 hydro-wind-solar integration concept, and it deserves a careful explanation because it is the one genuinely non-generic thing about this company's renewable strategy. Solar output is a fixed daily arch — nothing at night, a peak at noon, and a collapse whenever a cloud passes. Wind is worse: it goes where it wants. Grids handle this by holding fast-ramping capacity in reserve, usually gas or coal, which costs money and emits carbon.

But a hydropower station with a storage reservoir is the ideal complement, because water not run through a turbine is not wasted — it is stored. When the sun is high, the dams throttle back and the reservoir fills. When a cloud crosses or the sun sets, the turbines spin up within minutes. The reservoir becomes a giant, already-paid-for battery, and the wind and solar farms get to behave, from the grid's point of view, like firm dispatchable capacity.

The physics is real. What matters for investors is the scale and the cost.

On scale, SDIC Group's own materials describe the Yalong base as the world's largest integrated hydro-wind-solar base, targeting roughly 78 GW of all-renewable capacity by 2035 — some 30 large hydro and pumped-storage stations plus a 40-GW-scale wind and solar programme. At the end of 2025 about 22.55 GW was operational, of which roughly 3.3 GW was new energy, with approximately 12 GW under construction.¹¹ Two pumped-storage projects anchor the flexibility layer: 两河口 Lianghekou hybrid pumped storage, described as the world's largest of its type at 1.2 GW, and 道孚 Daofu at 2.1 GW, at the highest elevation of any such project.³¹¹

Take those targets seriously but not literally. Going from roughly 22.5 GW to 78 GW over a decade implies adding more capacity in the Yalong basin in ten years than the company built there in the previous twenty-five. That is a planning aspiration published by a state parent, restated in provincial planning documents, and revised periodically. It is not guidance. The near-term commitments are far more modest and far more checkable: in 2026 the company planned RMB 7.27 billion of equity investment and RMB 24.45 billion of capital-construction spending, funded by RMB 12.3 billion of domestic financing and RMB 17.7 billion of overseas debt facilities.³ That is roughly RMB 31.7 billion of capex against RMB 31.6 billion of 2025 operating cash flow — the entire cash generation of the business, committed before a single yuan of dividend.

One technical caveat is worth stating plainly, because the synergy story is usually told without it. Hydro reservoirs can absorb intermittency only to the extent they have spare storage and spare turbine capacity at the moment they are called on. In the wet season, when reservoirs are full and turbines are already running near maximum, the buffer is thin — the water has to go through the machines or over the spillway either way.

The complementarity is strongest in the dry season and in the shoulder months, and weakest in exactly the high-flow periods when curtailment risk on solar is highest. Pumped storage, which is why 两河口 Lianghekou is getting a hybrid pumped-storage plant bolted onto an existing reservoir and why 道孚 Daofu is being built from scratch, exists to close that gap. It is a real answer, and it is also several more billion renminbi of capital expenditure.

There is also a returns question that the sector has already started to answer badly. Renewable economics across China have deteriorated as capacity has raced ahead of transmission and demand. SDIC Power's own 2025 risk disclosure names it directly: curtailment risk has intensified in some regions, the rising share of market-based trading is pushing tariffs down, and project returns face downside risk.³ The company reported increased curtailment in Gansu, Xinjiang and Qinghai, lower solar tariffs in Liaoning, and weaker wind resource in Central China during 2025 — wind utilisation hours fell 263 hours to 1,747.³ Broader sector reporting through 2025 documented sharp volume-and-price pressure across Chinese renewable operators.¹⁹

It helps to size the near-term additions rather than the 2035 headline. Total installed capacity grew by 2,260.9 MW during 2025 to 46,895.6 MW, with clean energy adding enough to lift its share 1.7 percentage points to 72.12%.³ Wind and solar together reached 11.8 GW — from a standing start less than a decade ago.

That is a real build rate, and at roughly 2.3 GW a year it is also roughly a quarter of what would be required to hit 78 GW in the basin by 2035 on a straight line. The gap between the run rate and the target is not evidence of bad faith; it is evidence that the target assumes an acceleration that has not happened yet.

So the honest assessment is layered. The integration strategy is technically genuine and specific to this asset base — the reservoirs are a real competitive advantage in absorbing intermittency that a standalone solar developer cannot replicate. But it is being executed into an industry with falling returns, and it is the direct cause of the balance-sheet pressure that defines the bear case. Growth and leverage here are not two separate stories. They are the same story told from opposite ends.

VII. Capital Deployment: Growing Without a Playbook of Discrete M&A

Start with a number that reframes the entire capital-allocation discussion. By the end of 2025, SDIC Power's cumulative investment in Yalong River Hydropower Development Company stood at roughly RMB 126.9 billion, with a further RMB 17.7 billion added during 2025 alone.³ Total capital expenditure across all projects that year was about RMB 31.2 billion.³ For context, the company's entire market capitalisation in mid-August 2026 was around RMB 110 billion.[^15] SDIC Power has poured more money into one river than the market currently values the whole company at.

It is also worth noting how the company describes this capability in its own bond documentation. Among the competitive strengths it lists for creditors is, explicitly, its record of capital operations: since the 2002 backdoor listing it has used private placements, GDRs, rights issues, public follow-ons, convertible bonds, corporate bonds and medium-term notes to fund a large pipeline of projects under construction and in reserve.⁵ Most industrial companies list products, customers or cost position as competitive strengths. This one lists its ability to keep raising money. That is candid, accurate, and quietly revealing about where the business model's centre of gravity sits.

That is what makes the standard M&A scorecard useless here. There is no deal-by-deal record to grade — no acquisition multiples, no integration synergies, no goodwill impairments to interrogate. What there is instead is a twenty-five-year construction programme financed by a rotating combination of debt, retained earnings, JV capital calls and periodic equity issuance. The right diligence question is not "did they overpay?" It is "how have they funded it, and who has paid the price?"

Two recent events answer that with unusual clarity.

The first came on October 14, 2024, when SDIC Power and 川投能源 Chuantou Energy announced a joint RMB 15 billion capital injection into Yalong Hydro — RMB 7.8 billion from SDIC Power and RMB 7.2 billion from Chuantou, preserving the 52/48 split exactly. The money was earmarked for the mid-reach stations, principally 孟底沟 Mengdigou and 卡拉 Kala.²⁰ The obvious question, which the financial press asked at the time, is why an entity that had reported total assets of roughly RMB 179 billion at end-2023 and generated more than RMB 8.6 billion of annual net profit needed a RMB 15 billion equity infusion from its parents at all.²⁰ The answer is that Yalong Hydro is simultaneously a mature cash-generating cascade and an active construction site, and Chinese project financing requires a minimum equity contribution. The cash the river throws off is not free; it is pre-committed to the next dam.

The second event was the equity raise. Announced on September 17, 2024 and completed on March 4, 2025, SDIC Power placed roughly 550 million new shares at RMB 12.72 each to a single strategic subscriber — 全国社会保障基金理事会 the National Council for Social Security Fund — raising RMB 7 billion, with proceeds ring-fenced for Mengdigou and Kala.²¹[^24]²² The fund emerged as the third-largest shareholder at 6.88%, behind SDIC Group and, notably, 长江电力 China Yangtze Power.⁴

The credibility signal is genuine and worth naming precisely. China's sovereign pension fund is a long-duration, valuation-sensitive, politically insulated investor. Its decision to underwrite an entire RMB 7 billion placement, at a stated price, with a lock-up, and to take a board seat — the fund's Director of Stock Investment sits on SDIC Power's board — is a meaningfully stronger endorsement than a bought deal syndicated to hedge funds.³ It is not, however, a valuation judgment an outside investor can lean on: the NSSF's mandate includes deliberately channelling long-term capital into strategic state assets, and it bought at a price it negotiated with a state seller. Both things are true.

Now the dividend, and the puzzle it creates. SDIC Power paid out 50% of net profit in 2021, 50% in 2022, and then raised the ratio to 55%, which it has now maintained for three consecutive years through 2025 — RMB 0.5081 per share for 2025, RMB 4.07 billion in aggregate, against RMB 0.4565 per share for 2024.¹⁸²³⁴ The 2024–2026 policy sets a floor of at least 55%. Cash distributed has grown from roughly RMB 1.22 billion to RMB 3.69 billion over the policy's life.²²

The activist question writes itself: how can a company committing essentially all of its operating cash flow to capex simultaneously pay out 55% of earnings without borrowing to do it? The 界面新闻 Jiemian coverage put the tension bluntly, noting that total liabilities had climbed from about RMB 146.3 billion in 2020 to RMB 179.5 billion by the third quarter of 2024, that finance costs had run near RMB 4 billion annually from 2021 through 2023 despite falling interest rates, and that high leverage would likely require further equity financing — with the dilution that implies for existing minority holders.²² The optics of borrowing and issuing shares while distributing dividends are not flattering, and no amount of framing makes them so.

But the 2025 numbers complicate the bear case in a way that deserves acknowledgment. The debt-to-assets ratio fell 2.70 percentage points to 60.52%, the first meaningful improvement in years. Total liabilities rose only RMB 2.3 billion to RMB 189.8 billion while total assets rose RMB 17.0 billion. Attributable equity rose 17.19% to RMB 72.6 billion.

Financial expenses fell over a fifth. Operating cash flow rose 28%.⁴¹⁵ Some of that improvement is simply the RMB 7 billion equity injection landing on the balance sheet, which is a one-time effect and dilutive by construction. Some of it is genuine: cheaper refinancing at sub-2% coupons on new perpetual bonds, and real cost control.⁴

There is a second-layer point worth flagging on the funding mix. A meaningful share of SDIC Power's outstanding debt sits in perpetual bonds — 可续期公司债券, renewable corporate bonds — several of them issued in 2024 under a technology-innovation label at coupons between 2.19% and 2.30%, with a further RMB 400 million tranche placed in 2026 at 1.90%.⁴ Perpetuals are typically classified as equity rather than debt under Chinese accounting treatment, which flatters the reported debt-to-assets ratio while the cash coupon still leaves the building.

This is a common and entirely legitimate practice among Chinese SOE issuers, and SDIC Power discloses the instruments in full. But an investor tracking the deleveraging story should be aware that part of the improvement in the reported ratio reflects instrument classification rather than a reduction in fixed claims on cash flow. It is the single accounting judgment in these statements most worth understanding before drawing conclusions from the headline leverage number.

The 2025 annual report also introduced language that had not previously appeared with this emphasis — a commitment to "strictly abide by the red line for asset-liability ratio control" as one of three pillars of the strategy.³ Whether that is a durable constraint or a good year's phrasing is precisely what the next two years will test, given that the 2026 capex plan is larger than 2025's and the dividend floor is unchanged. One year of deleveraging into a capex acceleration is a data point, not a trend.

VIII. Current Management, Ownership & Credibility

If you wanted to design a chief executive for a company whose central asset is a river, you would probably end up with something close to 郭绪元 Guo Xuyuan.

His career, as the company's own disclosure lays it out, is a slow climb through the technical spine of the organisation: Director of Planning and Development, then Director of Engineering Management concurrently with Strategic Development and the Environmental Protection Management Centre, then Chief Infrastructure Engineer, then Deputy General Manager, then General Manager — and, along the way, Chairman of Yalong River Hydropower Development Company itself. He became Chairman of SDIC Power while continuing to chair the Yalong JV.³ He is a professorate senior engineer. He ran the river before he ran the company that owns it.

General Manager 于海淼 Yu Haimiao comes from an adjacent track: engineering technology and then work-safety and operations management, first at 天津国投津能 Tianjin SDIC Jinneng — one of the group's coal plants — then Chief Engineer and Deputy General Manager of SDIC Power, before being appointed to the top operating role.³ Between them, the two executives running the company are a dam builder and a power-plant operator. Neither is a financier or a dealmaker, which tells you something about what this organisation optimises for.

The incentive structure is the thing an investor accustomed to founder-led companies most needs to internalise. Guo Xuyuan's total 2025 remuneration was RMB 1.208 million — roughly US$170,000. Yu Haimiao's was RMB 1.097 million. The aggregate for all directors, supervisors and senior management was RMB 9.98 million.³ There are no meaningful personal equity stakes. There is no option package that pays off if the shares double. These executives are career civil servants of the energy system, rotated through by the parent, evaluated on operational and policy metrics as much as on shareholder returns.

That has a specific consequence. It largely removes the risk of empire-building for personal enrichment, and it largely removes the incentive for aggressive accounting. It also removes the upside case that a determined manager will fight the controlling shareholder for the minority's benefit — because the controlling shareholder appoints them, and because strategy is set jointly with the parent, not by the board alone.

The ownership table is worth reading closely, because it contains a genuine surprise. SDIC Group held 47.79% at the end of 2025 — down from historical levels above 50% as successive issuances diluted it, but still unambiguous control given the fragmentation of everything else. The second-largest holder, at 13.05%, is 长江电力 China Yangtze Power, with a further 3.24% held by its subsidiary 长电投资 Changdian Investment; the two are formally declared as acting in concert, giving the Yangtze Power group 16.29%.⁴ The National Council for Social Security Fund holds 6.88%, and two Yangtze Power and 三峡集团 China Three Gorges executives sit on SDIC Power's board.⁴³

Sit with that for a moment. The company's principal comparable — the one investors benchmark it against, the "big sibling" — is also its second-largest shareholder and has board representation. That is not the arrangement you would find in a competitive Western utility market, and it is worth flagging as a related-party consideration: the largest hydro operator in China holds a strategic stake in the third-largest, alongside the controlling central SOE parent. It reduces the plausibility of hostile competitive behaviour between them. It also means minority shareholders are the smallest and least organised constituency in the room.

A brief aside on board composition, because it is unusual enough to be worth noticing. Alongside the SDIC Group appointees, SDIC Power's board has included a director drawn from 长江电力 China Yangtze Power's own management ranks, a director who previously served as Chief Financial Officer and General Counsel of Yangtze Power and now holds a senior audit role at 三峡集团 China Three Gorges, and the National Council for Social Security Fund's Director of Stock Investment.³ In most markets, seating your largest sector competitor's finance chief on your board would be unthinkable.

In the Chinese SOE system, where the competitor is also a major shareholder and both answer ultimately to the same state, it is unremarkable. Investors should simply understand what it implies: the governance model here is coordination among state actors, not contestation between rival owners.

So how should management credibility be judged in this context? Not on vision — the strategy is largely handed down. On execution and consistency, and there the record is reasonably good.

On delivery: Lianghekou and Yangfanggou both entered full commercial operation in 2021 as scheduled, with Yangfanggou proving out a new EPC delivery model for million-kilowatt-class projects.⁸⁹ River closure was completed for Mengdigou and Kala, the two projects funded by the equity placement, within the first year of the raise — a checkable milestone against a stated use of proceeds.³ Chabulang and Suorong were commissioned. That is a construction organisation doing what it said it would do.

On narrative consistency: the disclosure of thermal exposure has been direct rather than deflecting. The 2025 annual report names fuel-price volatility, declining thermal utilisation hours, and rising flexibility-related operating costs as explicit profitability risks, with specific countermeasures — long-term contract performance rates, capacity revenue capture, ancillary-service income.³ The regional revenue commentary attributes declines to nuclear competition in Fujian and renewable build-out in Guangxi by name.³ This is more granular than sector norms.

On dividends: the 55% commitment has been honoured for three consecutive years through a period of heavy capex and, until 2025, rising leverage.¹⁸ A promise kept when it was inconvenient is worth more than one kept when it was easy.

Where the evidence thins out is on the central contradiction. Management has not offered a public, quantified reconciliation of how a rising dividend floor, a RMB 31.7 billion annual capex plan, and a falling debt-to-assets ratio can coexist beyond the one-off equity injection that made 2025 work. The May 2026 results briefings drew 33 questions across a Shanghai Stock Exchange webcast and a session with 28 institutional representatives, and the published summaries emphasise the clean-energy share, the Yalong base, and shareholder-value initiatives.¹⁸ What they do not surface is a specific answer to the leverage-versus-payout arithmetic. Investors should keep asking, and should note that the absence of a crisp answer is itself information.

There is no activist here and there will not be one; 47.79% control makes classic activism structurally impossible. The functional substitute has been the financial press — the Jiemian analysis of persistently high leverage being the sharpest example — and the discipline that comes from needing the NSSF, and eventually other outside investors, to keep writing cheques.²² That is a weaker accountability mechanism than a hostile shareholder, but it is not nothing: an issuer that needs capital-market access has to care what capital markets think.

IX. Stress Test: The 2022 Sichuan Drought

August 2022 was the month the abstraction became concrete.

The heatwave that settled over the Yangtze basin from early July intensified from August 7 into what meteorologists called the most extreme event in six decades. Rivers that feed Sichuan's dams shrank. Reservoir storage fell to roughly 1.2 billion cubic metres, about 4 billion below the previous year, and daily hydropower generation across the province fell by 51%.² Simultaneously, air-conditioning demand set records. A province that is normally one of China's great power exporters was suddenly short.

The government's response was blunt because there was no subtle option available. Industrial power supply was suspended from August 15 and extended thereafter, and the factory list read like a supply-chain map of the global electronics industry: 富士康 Foxconn's Chengdu plant, which assembles iPads and wearables for Apple; Intel; 宁德时代 CATL's Yibin battery works; トヨタ Toyota's Sichuan joint venture.¹ For roughly eleven days, one of China's most important manufacturing clusters ran on emergency allocation.

What did it do to SDIC Power? Less than you would expect, and the reason is instructive.

The first half of 2022, before the drought hit, was strong: controlled generation of 68.3 TWh, up 3.8%, an average on-grid tariff of RMB 0.359 per kWh, up 8%, and attributable net profit of RMB 2.35 billion.⁶ Lianghekou and Yangfanggou were contributing a full period for the first time, and the company noted explicitly that the new stations drove the generation increase.⁶ Then the drought landed in the third quarter. Full-year attributable profit came in at RMB 4.08 billion, implying a materially weaker second half.[^8]

And yet for the year as a whole, hydropower on-grid volume rose 12.37% to 98.6 TWh at an average tariff of RMB 0.272 per kWh, up 6.75%, and Yalong Hydro's net profit rose 15.73% to RMB 7.36 billion.¹² The company's own explanation is the clearest available evidence for the reservoir thesis: cascade optimisation across the Yalong, the full-year contribution of the two new stations, and the drawdown of upstream storage at Dachaoshan together offset — to a degree — the dry inflow conditions.¹²

That is the honest version of the drought test. Regulating storage did not make the drought irrelevant. It converted what would have been a catastrophic single-year output collapse into a bad year that new capacity could paper over. Note the qualifier: the offset came substantially from commissioning 4.5 GW of new stations, a one-time effect that cannot be repeated every time it fails to rain.

The subsequent record shows both the value and the limits of the buffer. In the first quarter of 2025, group hydropower generation rose 17.90% to 25.3 TWh, helped by the Yalong cascade having filled its reservoirs during 2024 and by better precipitation in parts of the basin — even as total group generation fell 1.55% and attributable profit rose only 2.1% to RMB 2.08 billion.²⁴ That is the reservoir working as designed: water banked in a good year, released in a weaker one.

But by the first quarter of 2026 the buffer was drawing down again. Yalong Hydro's generation fell about 10% year on year, its revenue fell 5% to RMB 6.35 billion, and its net profit fell 6% to RMB 2.82 billion.²⁵ Then the second quarter got worse: group generation fell 14.75% to 32.5 TWh.²⁶

One additional detail from the drought year deserves attention, because it complicates the tidy narrative. The 2022 relief came not only from water management but from price. Sichuan's power crisis, and the national coal squeeze running alongside it, pushed realised tariffs up across the board — SDIC Power's average hydro on-grid tariff rose 6.75% that year, and its blended first-half tariff rose 8%.¹²⁶ Scarcity raises the price of what you do manage to generate.

In a drought, a hydro operator loses volume and gains price simultaneously, and the net effect depends entirely on which moves further. In 2022 the two roughly cancelled at the Yalong level. There is no guarantee they will again, particularly as more volume clears through spot markets whose price formation in a supply crunch is a different and less tested mechanism than an administratively adjusted tariff.

The conclusion an investor should draw is unglamorous but important. Reservoir regulation is a real, physical, quantifiable risk-management asset — the difference between a run-of-river operator and SDIC Power is the difference between taking rainfall variance raw and smoothing it across seasons. But it smooths within and across a year or two, not across a multi-year dry cycle. Hydrology remains the single largest determinant of segment earnings, and nothing on the balance sheet changes that. Any model of this company that does not treat basin inflow as the primary independent variable is modelling the wrong thing.

X. Bull Case vs. Bear Case

Strip away the narrative and the investment debate reduces to a disagreement about whether a scarce asset can outrun a stretched balance sheet.

The bull case starts with the resource. SDIC Power's JV holds the exclusive development right to a basin with roughly 30 GW of exploitable hydropower, of which 19.2 GW is operating and 3.72 GW is approved or under construction, inside a country that has already allocated its best rivers.³ The economics of that asset are visible in the segment margin — nearly 59% gross in the Southwest region — and durable, because a dam's useful life is measured in generations and its fuel is free.³ Unlike a minority investor in a project, SDIC Power consolidates and controls the JV at 52%, so it captures the economics rather than merely participating in them.

The growth runway is unusually long for a utility. The Yalong hydro-wind-solar base targets roughly 78 GW by 2035 against about 22.6 GW operational today, with pumped storage adding a flexibility layer that makes the whole system more valuable than the sum of its megawatts.¹¹ The dividend commitment has been honoured at 55% for three years running, and the 2025 results showed the first genuine deleveraging in years alongside a 28% jump in operating cash flow.⁴¹⁵ And the presence of the National Council for Social Security Fund as a 6.88% holder, having underwritten an entire RMB 7 billion placement, is the kind of validation that is hard to manufacture.⁴

Finally, the relative-value argument: on capacity, profit and market value, SDIC Power trades at a substantial discount to 长江电力 China Yangtze Power, and a portion of that discount reflects things that are improving rather than permanent.

The bear case starts with the same balance sheet from the other side. Even after a good year, debt-to-assets sits above 60% and total liabilities exceed RMB 189 billion.⁴ Interest coverage of 4.12 times is adequate, not comfortable, for an asset base this capital-intensive.⁴ And the 2026 plan calls for roughly RMB 31.7 billion of investment against RMB 12.3 billion of domestic and RMB 17.7 billion of overseas financing — a funding profile that assumes continued, cheap, uninterrupted capital-market access.³

The thermal segment remains a genuine liability, not merely a low-multiple appendage. It cost the group more than half its net profit in 2021, and its structural position is deteriorating as utilisation hours fall under renewable competition — down 722 hours in 2025 alone.³[^8]

Concentration is the third leg. Yangtze Power spreads its hydrology across the upper Yangtze, Jinsha and multiple cascades; SDIC Power's hydro earnings are overwhelmingly one river, whose inflows are correlated across all of its stations by construction. When the Yalong is dry, everything is dry at once, as the first half of 2026 demonstrated.²⁶

Fourth: the dilution pattern. Weighted average shares outstanding rose from about 7.45 billion in 2024 to about 8.07 billion in 2025.[^8] Existing holders received a dividend and were diluted roughly 8% in the same twelve months. Whatever the intent, that combination — issue equity, pay dividends, keep borrowing — is a real transfer of value away from holders who do not participate in placements.

Fifth, and least priced: power-market reform. Nearly half of on-grid volume now clears through market mechanisms, spot markets have near-full provincial coverage, and the rules are still moving.³ The company has not been tested through a full hydrological cycle under this regime. Hydro, with near-zero marginal cost, may be structurally disadvantaged in a marginal-cost-clearing spot market — the very cost advantage that makes the asset wonderful can, under certain market designs, suppress the price it receives.

Myth versus reality

Four consensus narratives attach themselves to this stock. Each is partly true and partly wrong, and the difference matters.

Myth: SDIC Power is a hydropower company. Reality: hydropower was 45.43% of installed capacity at the end of 2025, with new energy including storage at 26.69% and the remainder thermal.³ It is a diversified generator with a very good hydro business inside it. The distinction shows up every time coal prices move.

Myth: the Lianghekou reservoir solved the drought problem. Reality: it dampened it. Group generation still fell 8.70% in the first half of 2026 on dry inflows, and the largest single offset in the 2022 drought year came from commissioning new stations, not from storage alone.²⁶¹² Regulation converts a cliff into a slope. It does not build a floor.

Myth: the sovereign pension fund's investment validates the valuation. Reality: it validates the asset and the policy alignment. The National Council for Social Security Fund bought at a negotiated price from a state seller with a mandate that explicitly includes deploying long-duration capital into strategic state assets.[^24]²² That is a strong signal about durability and a weak signal about entry price.

Myth: the stock is simply a cheaper Yangtze Power. Reality: it is cheaper for identifiable reasons — higher leverage, a 48% minority interest sitting between the river and the shareholder, a coal fleet, a single basin, and a lower payout ratio.⁴¹³ Whether the discount is too large is a legitimate question. Whether a discount is warranted is not.

Through the 7 Powers lens, the count is short and should be. Cornered Resource: yes, clearly and durably. Scale Economies: partially — cascade dispatch across a single basin produces genuine compensating benefits that a fragmented owner could not achieve. Switching Costs, Network Economies, Branding: absent, and any pitch that invokes them should be treated with suspicion. Process Power: arguable at the margin in ultra-high-altitude construction and cascade optimisation, but not demonstrated to produce excess returns. Counter-Positioning: no — incumbents are not structurally prevented from responding; they simply do not have the river.

The synthesis is this. The bull case does not rest on the quality of the asset, which is not seriously in dispute. It rests on execution of a multi-year, tens-of-billions build-out without letting leverage re-inflate, in a renewables market with falling returns, while holding a rigid dividend floor. The bear case rests on exactly the same three variables pointing the other way. This is not a debate about whether the river is good. It is a debate about whether the financing of the next river-sized capital programme leaves anything for minority shareholders.

Which is why the metrics to watch are narrow and specific. Three of them carry most of the information. First, Yalong basin inflow and hydropower utilisation hours — the primary earnings driver, and the number that determines whether a given year is good or bad regardless of anything management does. Second, the debt-to-assets ratio, which is the single cleanest test of whether the capex-plus-dividend commitment is being funded sustainably or with borrowed time.

Third, the realised average on-grid tariff alongside the share of volume sold through market trading, which together reveal whether power-market reform is compressing the value of the resource as the volume mix shifts. Everything else is downstream of those three.

XI. Risk Radar

Hydrology and climate. This is the dominant variable and it is not diversifiable within the portfolio. When Yalong inflows run dry, the highest-margin volume disappears first and there is no operational lever to replace it. The mechanism is direct: less water past the turbine equals less revenue at roughly 59% incremental margin. The first half of 2026 produced generation down 8.70% year on year, with the second quarter down 14.75% — an ordinary bad water year, not a catastrophe, and it still moved the group's output by nearly a tenth.²⁶ Climate variability appears to be widening the distribution of outcomes rather than shifting its mean, which argues for wider scenario ranges rather than a lower base case.

The second-order effect matters as much as the first. Because roughly two-thirds of attributable profit comes from one basin, a dry year on the Yalong is not a segment problem — it is a group problem that lands on a balance sheet already carrying heavy fixed charges. Fixed costs do not fall when the river does. Depreciation, interest and water fees continue at full rate against a smaller revenue line, which is precisely why hydro earnings swing more violently than a 59% gross margin would suggest.

Refinancing and cost of capital. With more than RMB 189 billion of liabilities and a 2026 plan requiring RMB 30 billion of new financing, the company is structurally dependent on continued access to Chinese credit markets at favourable rates.⁴³ The current environment is benign — new perpetual bonds priced at 1.90% in 2026 versus 4.59% on paper issued in 2019 — and that repricing is doing real work in the P&L.⁴ The risk is asymmetric: rates cannot fall much further from here, but a normalisation would flow straight through to a finance expense line that already runs at nearly RMB 2.7 billion.¹⁵

Coal price and thermal margin. The 2021 episode established the magnitude of the tail. The widened tariff band reduces it but does not remove it, and the company itself expects coal supply and demand to remain in tight balance through 2026, with geopolitics and weather capable of producing periodic disruptions.³ The compounding problem is that thermal is being squeezed from both ends simultaneously — fuel cost volatility on one side, falling utilisation hours on the other.

Power-market reform and regulation. The migration from administered feed-in tariffs to spot and medium-to-long-term market pricing is the most consequential structural change in the Chinese power sector in a generation, and it is incomplete. Rules are being adjusted in-flight, provincial designs differ, and the interaction between near-zero-marginal-cost hydro and marginal-cost clearing is genuinely unresolved. Treat this as an open question, not a solved one.

Execution in the new-energy build-out. Hitting multi-gigawatt annual additions in ultra-high-altitude terrain, on schedule and within budget, while curtailment risk rises in several of the company's operating regions and equipment costs fluctuate, is not a given.³ The track record on hydro construction is good. Renewables at this scale and altitude is a shorter track record against a harder returns backdrop.

Curtailment and grid access. A risk specific to the new-energy leg and easy to overlook, because it does not show up as a cost — it shows up as electricity that was generated and then thrown away. SDIC Power reported increased load curtailment in Gansu, Xinjiang and Qinghai during 2025, reducing output from existing projects.³ Transmission build-out is running behind renewable capacity build-out in several western provinces, and the Yalong base's own economics depend on ultra-high-voltage lines — the Yazhong and Jinsu DC links — reaching completion on schedule.³ A solar farm without a wire is a stranded asset.

Related-party and governance concentration. Not a near-term earnings risk, but a permanent structural feature: a 47.79% controlling parent, a 16.29% concert-party stake held by the sector's largest competitor, board seats held by that competitor and by the pension fund, and recurring capital calls into a jointly-controlled JV.⁴ The interests of these holders are broadly aligned with minorities most of the time. "Most of the time" is doing real work in that sentence.

XII. Playbook: Business & Investing Lessons

Owning a scarce natural resource is a categorically different business from owning a fungible one — and this company proves it inside a single set of accounts. The Southwest hydro region earned a gross margin near 59% in 2025 while the coal-heavy coastal regions earned in the teens and twenties, using the same management, the same balance sheet, the same country and the same customer.³ The only difference is the input. One is a river the company controls for decades; the other is a commodity priced by global markets. This is the cleanest natural experiment on resource quality available in a listed vehicle, and it is a useful lens for any asset-heavy business: ask what the input is, who sets its price, and whether the answer changes over fifty years.

State-owned capital allocation runs on rules that will frustrate anyone who assumes shareholder-return maximisation. A dividend floor coexisting with rising leverage and repeated equity issuance is not necessarily a mistake or a governance failure — it is what happens when the controlling shareholder's objective function includes national energy security, dual-carbon targets and provincial development alongside the share price. Investors in SOEs need to underwrite that reality explicitly rather than model it away. The corollary: in an SOE, management credibility is best assessed on execution against checkable operational commitments, because strategy-setting credibility largely belongs to someone who is not in the room.

Regulating storage is physical infrastructure that performs a financial function, and it should be valued as such. A reservoir converts a volatile revenue stream into a smoother one, and a smoother stream is worth more per unit than a volatile one. That is why Lianghekou changed this company's earnings profile more than its 3 GW nameplate would suggest, and why pumped storage matters disproportionately to the renewable build-out.⁸¹¹ The general lesson: in businesses exposed to variable natural inputs, buffering capacity has option value that rarely shows up in a capacity or capex figure.

A cornered resource and pricing power are not the same thing, and conflating them is the most expensive mistake available in resource businesses. Owning something irreplaceable guarantees that nobody can compete away your cost position. It says nothing about who captures the surplus. On the Yalong, the surplus is split between the state through tariff regulation, the grid through dispatch and market design, a 48% minority partner through the JV, and finally the listed company's shareholders. The resource is uncontested; the rent is contested at every step. When evaluating any scarce-asset story — mines, spectrum, ports, rivers — the second question after "can this be replicated?" should always be "and who gets to keep the money?"

Being the second-best asset in an excellent industry is a legitimate investment case — at the right price and with a higher evidentiary bar. SDIC Power is not Yangtze Power and never will be: a third of the hydro capacity, a fifth of the profit, more leverage, more commodity exposure, more concentration, a lower payout.¹³³⁴ None of that makes it uninvestable. It makes it a different proposition — one where the discount has to compensate for balance-sheet risk and hydrological concentration, and where the burden of proof on capital discipline is correspondingly heavier. The failure mode is not buying the second-best asset. It is paying first-best prices for it and assuming the gap closes on its own.

XIII. Epilogue: The State of Play

As of mid-August 2026, SDIC Power had not yet published its interim report — the company's half-year disclosure has typically landed at the end of August — so the most recent complete picture comes from the first quarter and from the operating-data announcements that followed.²⁶

That picture is of a dry year being managed rather than a crisis being weathered. First-quarter revenue fell 4.63% to RMB 12.51 billion and generation fell 2.78% to 37.9 TWh, with the company attributing the hydro decline to dry inflows in the Yalong basin and the Xiaosanxia stations, partly offset by better rainfall at Dachaoshan and by shorter maintenance outages at Huaxia Power in Fujian.¹⁶²⁷ Average on-grid tariff was RMB 0.354 per kWh, essentially flat.¹⁶ Attributable net profit nonetheless rose 1.91% to RMB 2.12 billion — the same pattern as 2025, where volume fell and profit rose because costs, and especially financing costs, fell faster.²⁷

The second quarter was harder: generation down 14.75%, taking the first half to 70.4 TWh, an 8.70% decline.²⁶ Read through the JV partner's disclosure and the shape becomes clearer — Yalong Hydro's first-half generation fell sharply while its net profit fell only single digits, because realised tariff per unit and profit per unit both rose.²⁸ That is the cascade doing exactly what it is built to do in a dry year: sell less power, but sell it better.

The forward signal, such as it is, turned in July. Yalong basin inflows in July 2026 ran roughly 41% above the prior year, against a very weak 2025 comparison.²⁸ If that persists, the second half should look materially different from the first — which is a reminder, delivered on schedule, that the most important variable in this company's income statement is measured by hydrologists rather than by management.

A note on what the market is being told and how. SDIC Power does not hold Western-style quarterly earnings calls with open analyst Q&A transcripts. What it runs instead is the Chinese-market equivalent: an annual 业绩说明会 results briefing, conducted in 2026 across two sessions — one webcast through the Shanghai Stock Exchange platform on May 8, which fielded 33 questions, and one in-person session on May 11 with 28 institutional representatives and major brokerages, with Chairman Guo Xuyuan, General Manager Yu Haimiao and Chief Accountant and Board Secretary 周长信 Zhou Changxin all present.¹⁸ The published summaries emphasise the clean-energy share of capacity, the Yalong base build-out, thermal's supply-security role, and the 15th Five-Year Plan priorities — offshore wind, desert-scale solar, storage and virtual power plants.¹⁸ For an investor, the format is a genuine disclosure constraint: there is no verbatim transcript in which a management answer can be tested against the same management's answer a year earlier. Judgments about narrative consistency have to be made against filings rather than against live speech, which is a slower and blunter instrument.

Three things are worth watching from here. Whether the pace of new-energy additions in the Yalong basin actually tracks toward the 2035 target or quietly slips, and at what return. Whether the debt-to-assets ratio continues to fall now that the one-time equity injection has been absorbed and the 2026 capex plan is larger than 2025's.

And how power-market reform is actually implemented in Sichuan and the provinces its transmission lines feed — because a company that sells nearly half its output into markets whose rules are still being written has a valuation that depends on rules nobody has finished writing.

The closing thought is the one the whole story keeps returning to. SDIC Power owns something genuinely irreplaceable: a river, permanently, with the exclusive right to develop it and a partner structure that lets it keep the majority of the economics. It also operates inside a system where the controlling shareholder's priorities extend well beyond the share price, and where the physical input to its best business arrives, or does not, entirely at the discretion of the weather. Those are two very different kinds of uncertainty. Owning this company means being comfortable with both of them at the same time.
