EDP Group: Portugal's Green Energy Giant Goes Global
I. Introduction & Episode Roadmap
The story begins on a rain-slicked April morning in 1974, when young Portuguese army officers—exhausted by endless colonial wars draining 40% of the national budget—broadcast a banned folk song on the radio as a signal to begin the most peaceful revolution of the twentieth century. Citizens poured into the streets, placing red carnations in rifle barrels. Within days, Portugal's 48-year fascist dictatorship collapsed. Within a year, the country had nationalized its electricity sector. Within five decades, the scrappy state monopoly born from this revolution would transform into one of the world's most valuable renewable energy companies.
EDP is a Portuguese electric utilities company, headquartered in Lisbon, founded in 1976 through the merger of 14 nationalised electricity companies. Today it operates across four continents, employs more than 12,000 people, and generates over 85% of its energy from renewable sources. The question worth exploring: How did a post-revolution state monopoly transform into one of the world's largest renewable energy companies—and what does its journey reveal about the interplay between geopolitics, capital flows, and the energy transition?
This analysis will trace EDP through five defining eras: the nationalization that forged it, the privatization that freed it, the audacious American bet that transformed it, the Chinese partnership that funded it, and the hostile takeover that tested it. Along the way, it examines the strategic choices, the lucky timing, and the structural advantages that positioned a peripheral European utility at the vanguard of global decarbonization.
In 2023, EDP reported a net consolidated profit of €952 million and an EBITDA of €5.020 billion, while its net debt amounted to €15.3 billion, resulting mainly from investments in renewables and electricity grids. EDP has made significant investments in the energy transition, allocating 96% of its total 2023 investments to renewable energy projects.
For investors evaluating EDP today, the central question isn't whether renewables will grow—that's nearly settled. The question is whether EDP's particular combination of geographic diversification, regulated assets, and Chinese capital creates durable competitive advantage or lingering strategic vulnerability.
II. Portugal's Electricity History & The Carnation Revolution Context
The Long Road to Light
The history of Portugal's electrification begins not with revolutionary fervor but with royal celebration. The year was 1878, and on September 28th, during the celebration of Prince D. Carlos's fifteenth birthday, electric lamps illuminated the Cascais Citadel esplanade—the first known electric experiment in Portuguese territory. The streets, not homes, were the first battleground of electrification.
For the next century, Portugal's electricity sector remained fragmented, underdeveloped, and firmly in private hands. Multiple regional operators—some domestic, some foreign-owned—divided the country into patchwork territories with little coordination. By the early 1970s, Portugal remained one of Western Europe's poorest nations, still maintaining a vast colonial empire in Africa while its domestic infrastructure lagged decades behind neighbors.
The Revolution That Changed Everything
The Carnation Revolution, code-named Operation Historic Turn, was a military coup in Portugal by officers that overthrew the Estado Novo regime on 25 April 1974. The regime had ruled Portugal since 1933—longer than Franco in Spain, longer than Mussolini in Italy.
Before April 1974, the intractable Portuguese colonial war in Africa consumed up to 40 percent of the Portuguese budget. A country of nine million inhabitants was supporting an army of 200,000, which suffered 8,300 casualties over 12 years. At least ten times that number of Africans were killed.
Junior army officers from the clandestine Armed Forces Movement (MFA), sick and tired of the failing wars, organised a coup on 25 April 1974. What made the Carnation Revolution remarkable wasn't just its success—only five people lost their lives throughout the entire country, and two of those deaths were accidental. Rarely in history has an entire nation changed hands in such a short time at so little cost of human life.
The Carnation Revolution got its name from the fact that almost no shots were fired, and from restaurant worker Celeste Caeiro who offered carnations to soldiers when the population took to the streets to celebrate the end of the dictatorship. Other demonstrators followed suit and placed carnations in the muzzles of guns and on soldiers' uniforms.
The Nationalization Wave
On 15 April 1975, the fourth provisional government nationalised dozens of companies in sectors including petroleum, electricity, gas, tobacco, breweries, steelworks and cement. The revolution led to the nationalization of major sectors of the economy, including banking, transportation, heavy industries, and communications. It also led to land reform, with agricultural land being redistributed to the rural poor.
The electricity sector was central to this transformation. The new revolutionary government viewed centralized, state-controlled power as essential for democratizing energy access and modernizing a nation that had languished under decades of underinvestment. Fourteen separate electricity companies—some large, some regional—would be merged into a single national champion.
Understanding the Carnation Revolution context is essential for understanding EDP's DNA. The company wasn't created by market forces or entrepreneurial vision. It was created by political will—by a nation that had just overthrown authoritarianism and believed state ownership of critical infrastructure was the path to equitable development. This origin shaped EDP's culture, its relationship with government, and its eventual evolution.
III. Birth of EDP: Nationalization & State Monopoly Era (1976–1996)
Forging a National Champion
EDP was founded as Electricidade de Portugal, E.P. by the Portuguese government through the Decreto-lei n.Âş 502/76 published on 30 Jun 1976, merging 14 former energy companies that had been nationalised by 1975 in the aftermath of the regime change in 1974, of which the most significant had been the Companhia Portuguesa de Eletricidade (CPE).
The timing could hardly have been worse. Portugal faced industrial precariousness, a disorganized electricity sector, and a sudden oil crisis—not favorable factors for launching a state-owned enterprise. The country was also absorbing nearly one million retornados—Portuguese citizens fleeing the former African colonies after decolonization. This demographic upheaval strained every national institution.
From its inception, EDP's ownership was wholly state-controlled. The Portuguese state was the sole shareholder, with the overarching objective to democratize energy access and establish a unified, nationwide supply. In a country where rural electrification remained incomplete, this was no small ambition.
Building the Infrastructure
Through the late 1970s and 1980s, EDP pursued the unglamorous but essential work of expanding Portugal's electrical infrastructure. The company built transmission lines into remote regions, standardized voltage across formerly incompatible networks, and invested in hydroelectric capacity to reduce dependence on imported oil. Portugal's mountainous northern terrain made it ideally suited for hydropower, and EDP gradually developed a portfolio of dams that would later prove strategically valuable as renewable assets.
The state monopoly period instilled certain characteristics into EDP's organizational culture. Decisions moved through bureaucratic hierarchies. Political considerations shaped investment priorities. Employee headcounts reflected social policy as much as operational efficiency. But the monopoly also created something valuable: a workforce with deep engineering expertise and intimate knowledge of Portugal's grid architecture—intellectual capital that would prove essential for later expansion.
The Transformation Begins
In 1991, through Decreto-Lei n.º 07/91 of 8 January, the Government changed EDP's legal status from a Public Company to a Public Limited Company with exclusively public capital. This legal restructuring—seemingly technical—was the first step toward eventual privatization. By converting EDP into a shareholder-owned company (with the state as sole shareholder), Portugal created the corporate framework necessary for future capital raises.
In May 1994, after a profound restructuration of EDP carried out between 1991 and 1993, under the Tutelary of Mira Amaral, Minister of Industry and Energy, the EDP Group was constituted with a Holding and 19 companies, six of them responding to the main core business activities including electricity production, electricity transportation, and four companies of regional electricity distribution.
This restructuring separated EDP into distinct business units—generation, transmission, distribution—mirroring the functional unbundling that European regulators would later mandate across the continent. Portugal was, somewhat surprisingly, ahead of the curve.
EDP was the monopolist producer and distributor until 2007, when the sector was, once again, opened up to private initiative and the Iberian wholesale energy market (MIBEL) was put into practice.
By the mid-1990s, EDP controlled roughly 92% of Portugal's installed generating capacity, produced about 85% of the country's electricity, and distributed 100%. It was the largest industrial group in Portugal—and the government had decided to sell it.
IV. The Privatization Journey: From State Monopoly to Public Company (1997–2011)
The IPO That Launched a Transformation
The first phase of EDP's privatisation took place in June 1997, with the transfer of shares representing 29.99% of EDP's capital. EDP's shares were initially listed on the Euronext Lisbon's official securities market on 16 June 1997. The Company later underwent 8 additional privatisation phases from 1997 to 2011.
In EDP's initial public offering (IPO) in June 1997, some 200,000 investors were targeted, representing a substantial increase over the levels of around 90,000 in some previous Portuguese offerings.
In 1997, a privatization program was initiated by the government of Portugal ruled by economic criteria and functions, as a tool to reduce public debt, boosting the capital market, improving the financial situation of the economy, and competitiveness of the national economy.
The privatization occurred in carefully staged phases—a deliberate strategy to maximize proceeds while gradually shifting ownership from public to private hands. The Portuguese government retained a golden share, preserving influence over strategic decisions even as it sold down its stake. Each successive privatization phase brought new institutional investors, expanded the shareholder base, and improved market liquidity.
European Market Liberalization
Since the nineties, EDP went through a major transformation as Portugal opened up the electricity market to private investors, which led to the separation of EDP's network distribution activities, the breakup of REN, the national power grid operator, and the split of the distribution and generation businesses within EDP.
This process came in line with the European energy market liberalization waves, which began with the acknowledgement of the inefficiencies afflicting the utilities market, due to a strong State influence in the companies' activities.
The European liberalization directives required member states to unbundle vertically integrated utilities, separating competitive activities (generation, retail) from natural monopolies (transmission, distribution). For EDP, this meant divesting its transmission business—creating REN as an independent grid operator—while retaining generation and distribution assets.
These regulatory changes fundamentally altered EDP's business model. No longer a protected monopoly, it faced competition in generation and retail while its distribution business operated under regulated returns. This hybrid structure—part competitive, part regulated—created natural hedging that would prove valuable through subsequent market cycles.
Post-Privatization Performance
By 2006, EDP was ranked as the seventh largest utility in Europe by market capitalization. The company reported revenues of approximately €12.6 billion and a net profit of €1.5 billion for that year.
Privatizations helped to improve the modernization and innovation of the economy, companies like EDP increased their levels of performance, modernization and innovation after being privatized.
The transformation was striking. A state monopoly that had operated primarily as a public works agency morphed into an investor-focused corporation benchmarked against European peers. Management implemented cost controls, customer service improvements, and international expansion strategies that would have been unthinkable under state ownership.
According to the Portuguese newspaper Jornal de NegĂłcios, EDP's sale to privates allowed the Portuguese State to earn 9.7 billion euros. The privatization was, by any measure, a financial success for Portuguese taxpayers.
But the most transformative decision lay ahead. As a newly privatized company flush with capital market access, EDP could pursue growth opportunities that state ownership had precluded. And in March 2007, it made a bet that would reshape its entire trajectory.
V. INFLECTION POINT #1: The Horizon Wind Energy Acquisition (2007)
The Transformative Bet
In March 2007, the group made a US$3 billion takeover of Horizon Wind Energy, the Texan-based wind power producer. At the time, it was the largest renewable energy deal to date and made EDP the fourth-largest wind power producer in the world.
To appreciate the boldness of this decision, consider the context. In 2007, wind energy remained niche—expensive, intermittent, and geographically limited. Solar photovoltaics were prohibitively costly. The phrase "energy transition" hadn't entered mainstream discourse. EDP was a mid-sized European utility; Horizon Wind Energy was a development-stage American wind company owned by Goldman Sachs. The acquisition price—nearly $3 billion for a company with limited operational capacity—represented a massive bet on an uncertain future.
EDP signed an agreement to acquire 100% of the share capital of Horizon Wind Energy LLC, a leading developer, owner and operator of wind power generation in the United States, from The Goldman Sachs Group, Inc. Since it was founded in 1999, Horizon has been one of the most successful wind developers in the United States, largely because of its highly experienced management team. The company currently owns 559 gross MW of operating wind projects and has 997 MW of projects under construction.
Horizon also has a strong pipeline of projects in several stages of development in 15 different states across the country, with combined aggregate generating capacity of over 9,000 MW.
The Strategic Logic
Why would a Portuguese utility pay $3 billion for a Texas wind company? Several factors converged:
In 2005, the company (then called Zilkha Renewable Energy, and owned by Selim Zilkha and Michael Zilkha) was purchased by investment bank Goldman Sachs for an undisclosed sum and renamed Horizon Wind Energy. In 2007, the company was acquired by Energias de Portugal for $2.15 billion.
Goldman Sachs had assembled Horizon precisely to be sold. The investment bank understood that European utilities—flush with cash from privatization, mandated to meet renewable targets, and facing saturated home markets—were natural buyers for American wind assets. EDP, despite its modest size relative to giants like Enel or Iberdrola, moved faster and paid a premium that competitors considered excessive.
The final price of the transaction was set at an enterprise value of USD 2,740 million for Horizon, already including the capital expenditures supported by Goldman Sachs between the end of 2006 and today.
The acquisition wasn't just about assets—it was about capabilities. Horizon's management team had spent nearly a decade navigating the Byzantine process of developing wind projects in America: securing land rights, negotiating power purchase agreements, managing interconnection queues, and accessing federal tax credits that were essential for project economics. This expertise couldn't be built overnight; it had to be acquired.
The Creation of EDP Renováveis
EDPR was established in 2007 to hold and operate the growing renewable energy assets of parent company Energias de Portugal (EDP Group), Portugal's largest utility company headquartered in Lisbon.
The Horizon acquisition provided the foundation for a new subsidiary—EDP Renováveis (EDPR)—that would consolidate EDP's renewable energy activities globally. EDP listed 22.5% of the company in an initial public offering on Euronext Lisbon in June 2008 at 8.00 Euro per share, upon which it immediately became a member of the benchmark PSI-20 index as its fifth-largest company by market capitalisation.
The EDPR IPO raised a total of €1.566 billion. Priced at €8.00 per share – midway between the offering price range of €7.40 to €8.90 per share – the Public Subscription Offer was oversubscribed by 87.9 times the total amount.
The partial IPO served multiple purposes: it provided immediate cash to reduce the debt incurred from the Horizon acquisition, established a public market valuation for the renewable assets, created currency for future acquisitions through EDPR stock, and positioned EDP for the renewable energy boom that management anticipated.
The Early Renewables Vision
In 2006 35% of the energy produced by EDP was from renewable energy sources, and, as of the end of 2007, the company announced that 39% of its energy was already emissions-free and that it was aiming for a 75% renewable energy production by 2013.
This target—75% renewable by 2013—was extraordinarily ambitious for its time. Most European utilities were incrementally adding wind capacity while defending coal and gas portfolios. EDP, from a relatively small base, was betting the company on green energy.
EDP Renováveis is the fourth-largest generator of wind energy globally. EDPR has continued to grow in recent years and is now present in 13 international markets.
The Horizon acquisition transformed EDP from a regional Iberian utility into a global renewable energy player. Within a year, EDP controlled wind farms across America's wind belt—from Texas to Illinois to Iowa. The decision looked prescient almost immediately: federal production tax credits, state renewable portfolio standards, and declining turbine costs combined to make American wind development extraordinarily profitable through the late 2000s.
VI. INFLECTION POINT #2: China Three Gorges Partnership (2011)
Crisis Creates Opportunity
The year was 2011, and Portugal was drowning. The European sovereign debt crisis had pushed the country to the brink of default. Locked out of bond markets, Portugal negotiated a €78 billion bailout from the European Union, European Central Bank, and International Monetary Fund—the troika that would impose austerity measures on the Portuguese economy for years to come.
One condition of the bailout: Portugal would sell state assets to reduce debt. The remaining government stake in EDP was prominently on the block.
CTG's investment, completed a decade ago, was spurred by the Portuguese government's sale of relevant assets as a result of a rescue plan necessitated after national debt levels skyrocketed.
As a result, Chinese companies took advantage of attractive asset pricing in a depressed economy, together with the Portuguese Government's openness to foreign capital, to expand their global reach, by entering the European market.
The Chinese Suitor
The China Three Gorges Corporation was established in September 1993 with the aim to develop the Yangtze River and create the Three Gorges Project, the world's largest hydropower project to be constructed. China Three Gorges Corporation is fully under the governance of the State-owned Assets Supervision and Administration Commission of the State Council (SASAC), an institution that is responsible for carrying out the obligations assigned by the Chinese Communist Party's Central Committee.
CTG wasn't just any Chinese state enterprise—it was the organization that had built the world's most ambitious hydroelectric project, a dam spanning the Yangtze that had required the resettlement of over one million people. Having largely completed that mission, CTG was now seeking global expansion in clean energy.
CTG ended up winning the bid against the German firm E.ON, and the Brazilian groups Electrobras and Cemig. The final offer accepted consisted in a global price of €2.69bn, representing a premium of 54% relatively to EDP's share market price.
Chinese companies often presented the best offers, through the support and financial backing provided by the Chinese State to SOEs. In this context, the CTG's minority acquisition of EDP, for an amount of €2.7bn in 2011, marked the beginning of a series of investments in Portugal in the subsequent periods.
The Strategic Partnership
The investment was structured as more than a passive stake. EDP and CTG, China's largest clean energy group, will combine efforts to become worldwide leaders in renewable energy generation, by means of a strategic partnership in renewable generation projects, where EDP will lead in Europe (in the countries where EDP is present), US, Canada, Brazil and other selected South American markets and CTG will lead in Asia markets where it is present.
In accordance with the envisaged partnership, CTG will invest €2bn until 2015 (including co-funding capex) for stakes between 34-49% in 1.5 GW of operational and ready-to-build renewable energy generation projects. Moreover, the partnership with CTG includes a firm funding commitment by a Chinese financial institution to EDP at corporate level in the amount of up to €2bn for a maturity up to 20 years.
This was the strategic logic: EDP gained access to patient, long-term capital from a partner whose cost of capital approached sovereign rates. CTG gained a platform for global expansion, access to Western renewable energy expertise, and a foothold in markets—especially the United States—where direct Chinese investment faced scrutiny.
China Three Gorges' strong emphasis on the internationalization process has led to status as an exceptional outcome of the Belt and Road Initiative (BRI). It has accelerated its investments globally as part of their strategic development positioning plan; "Going Global".
The Balance Sheet Impact
The partnership strengthens EDP's credit profile through the increase of EDP's financial liquidity position with the extension by two years of the coverage of EDP's financing needs till mid-2015 and targeting a Net Debt/EBITDA ratio below 3.0x by 2015. Moreover, the partnership allows EDP to diversify growth opportunities and is expected to be EPS enhancing from 2012 onwards.
For EDP, the CTG partnership arrived at the perfect moment. The company had leveraged itself to acquire Horizon; the European debt crisis had constrained refinancing options; and growth opportunities required fresh capital. CTG's investment provided all three: immediate liquidity, long-term funding commitments, and co-investment capacity for new projects.
CTG and EDP have held discussions centered on strengthening their collaboration in sustainable energy technology R&D, global project investments, alternative markets, and the mutual exchange of expertise. This partnership has significantly contributed to CTG's sustainable growth on a global scale.
By 2014, CTG's stake had grown through additional purchases, making it EDP's largest shareholder by a substantial margin. EDP's second-largest shareholder is Blackrock, with 7.38 per cent, followed by Spain's Oppidum Capital (Masaveu family), with 7.2 per cent.
The partnership transformed EDP's financial position, enabling continued expansion through the mid-2010s. But it also raised questions that would come to dominate discussion of the company: What were China's long-term intentions? And did EDP's Chinese shareholder create strategic vulnerabilities in an era of US-China decoupling?
VII. INFLECTION POINT #3: The Failed Hostile Takeover (2018–2019)
The Power Play
In late 2018 EDP's largest shareholder, China Three Gorges Corporation, proposed a hostile takeover of EDP. This was ultimately rejected at the shareholders meeting on 24 April 2019.
CTG in May 2018 made a €9.07 billion all-cash offer to purchase the remaining 76.7% stake in EDP that it does not already own, but the price of €3.26 per share was deemed too low by the utility's board.
Energias de Portugal SA has rejected 9 billion euro ($10.7 billion) buyout bid from Chinese state-owned utility China Three Gorges Corp., saying the price is too low. The Three Gorges offer represented barely a 5% premium on EDP's previous closing price.
The offer arrived at an inflection point. CTG had spent seven years as a patient strategic partner, supporting EDP's growth while building its stake. Now it wanted control—full ownership of a company that had become one of the world's largest renewable energy players.
For Three Gorges, which spent two decades building a hydro-power plant spanning China's Yangtze River, the deal would bolster its efforts to expand abroad and give it deeper access to markets in Europe, the U.S. and Brazil. China's biggest renewable-energy developer already is the largest shareholder of EDP with a 23 percent stake and now is seeking more than 50 percent.
The Price Problem
A market analyst said buyers have usually paid a premium of about 30% in similar deals. The analyst said Three Gorges' offer may be its first attempt, and the company may raise the price in following negotiations.
EDP's board rejected the offer as fundamentally undervaluing the company's assets and growth prospects. "We believe the price offered is too low for China Three Gorges to achieve full control of a vehicle that provides, among other things, a strategic footprint into U.S. renewables," Javier Garrido, an analyst at JPMorgan Chase & Co., said in a note.
But the price was only part of the story. Geopolitical concerns complicated every aspect of the transaction.
The Geopolitical Dimension
The rejection of the bid by the Chinese energy behemoth comes amid growing unease within the European Union over a surge of Chinese state investment in and around the bloc.
Another factor that led to the bid being blocked is the growing suspicion among various government departments about the increasing amount of Chinese investments in key European industries.
The timing couldn't have been worse for CTG. The late 2010s saw intensifying scrutiny of Chinese state investment across Western democracies. The Committee on Foreign Investment in the United States (CFIUS) had expanded its review authority. European nations were implementing investment screening mechanisms. The notion that critical infrastructure should remain under domestic—or at least allied—control was gaining political traction.
EDP, with substantial operations in the United States, fell squarely into the crosshairs. A Chinese state enterprise acquiring control of wind farms across America's heartland raised obvious national security concerns—concerns that would only intensify in subsequent years as US-China relations deteriorated.
The Voting Rights Defense
The voting rights reform had been demanded by the Portuguese stock exchange as a condition for its green light to the Chinese offer. EDP's current rules prevent any shareholder from having more than 25 percent of the voting rights, regardless of the size of its shareholding.
China Three Gorges Corp.'s proposed takeover of EDP collapsed after 56% of EDP shareholders voted against the reformation of voting rights, which is a prerequisite to CTG's proposal. Removing a 25% cap on voting rights at EDP was one of the conditions for CTG's plan to take over the company.
This structural defense proved decisive. EDP's bylaws included a 25% voting cap—a common anti-takeover provision that prevented any single shareholder from exercising majority control regardless of ownership percentage. To complete its takeover, CTG needed shareholders to remove this cap. They refused.
The shareholder vote reflected multiple considerations: the inadequate premium, concerns about Chinese control, uncertainty about the company's strategic direction post-acquisition, and simple inertia—minority shareholders who were comfortable with the status quo.
The Aftermath
In January 2021, alterations in EDP's shareholder structure took place as a result of the failed takeover. CTG's stake was modified to 19.03%. As of now, in February 2022, China Three Gorges boosted its equity position in EDP from 19.03% to 20.22%, for the first time in over 2 years.
China Three Gorges is currently the largest shareholder of EDP, with the corresponding voting rights, followed by Blackrock, Inc., and Oppidum Capital as the respective second and third largest shareholders, with approximately 7% equity each.
EDP's chairman, Antonio Mexia, announced after the shareholders' general assembly that "we are confident about the future of the company and our partnership with China Three Gorges."
The failed takeover demonstrated that EDP's defensive mechanisms worked. It also clarified the limits of the CTG relationship: China would remain the largest shareholder, but wouldn't achieve control—at least not through the public markets. Whether this arrangement represents a stable equilibrium or merely a pause before the next attempt remains an open question.
VIII. The Modern Era: Accelerating the Energy Transition (2019–Present)
Strategic Acquisitions and Partnerships
In 2020, EDP agreed to buy Viesgo, more than doubling its presence in Spain's electricity distribution market.
EDP completed the acquisition of Viesgo, for an enterprise value (100%) of €2.7 billion. This transaction includes the establishment of a long-term partnership with Macquarie Super Core Infrastructure Fund for electricity distribution business in Spain, which will be 75.1% owned by EDP and 24.9% by MSCIF.
The Viesgo deal exemplified EDP's evolved strategy: acquire regulated distribution assets (which provide steady cash flows), partner with infrastructure-focused institutional capital (which accepts lower returns for lower risk), and divest generation assets through creative structures that preserve management and operational control while reducing capital intensity.
In November 2019, EDP announced that it had reached a 50/50 Joint Venture agreement with the French gas and power company Engie to merge their fixed and floating offshore wind power activities, primarily targeting markets in Europe, the United States and selected geographies in Asia.
This joint venture—Ocean Winds—positioned EDP in offshore wind, the renewable technology with the largest capital requirements and longest development timelines. Rather than build offshore capabilities alone, EDP partnered with Engie, combining development pipelines and sharing risk.
Ocean Winds, founded by EDP Renewables and ENGIE in 2020 to develop offshore projects, is on a trajectory to reach the 2025 target of 5 to 7 GW of projects in operation or construction, and 5 to 10 GW under advanced development.
Leadership Transition
Miguel – who graduated with a mechanical engineering degree from the University of Strathclyde in Scotland and an MBA from MIT – joined EDP in 2000, working on strategy and corporate development, along with mergers and acquisitions. He became CEO of both EDP Group and EDP Renewables in January 2021.
Miguel Stilwell d'Andrade, Interim CEO of EDP, said: "This landmark transaction reinforces our positioning at the forefront of the energy transition and marks the beginning of a long-term partnership with Macquarie in electricity distribution networks in Spain, one of EDP's core markets."
Miguel Stilwell d'Andrade brought an unusual combination of strategic and operational experience. Having worked on EDP's corporate development deals for two decades, he understood how the company had assembled its current portfolio. And having run the Portuguese distribution business, he understood operations at the ground level.
Shortly after becoming CEO, Miguel oversaw a revision of the EDP business plan. It focused heavily on the energy transition and posited three key pillars: Accelerated and sustainable growth, environmental, social and governance (ESG) excellence, and making the company "future-proof".
The Name Change
On 10 April 2024, the company decided at a general meeting of shareholders to change its name to simply "EDP, S.A.", dropping "Energias de Portugal" from the name. The objective was to "simplify the image" and "adjust the corporate name to an increasingly global company".
This rebranding captured a fundamental shift. EDP was no longer Electricidade de Portugal—a Portuguese electricity company with international operations. It was EDP—a global energy company that happened to be headquartered in Portugal. The new identity acknowledged that the majority of EDP's value creation now occurred outside its home market.
Current Investment Plans
Deploy ~€12 billion of gross investment between 2026 and 2028 at enhanced returns, including ~€7.5 billion in EDPR (in wind, solar and battery energy storage systems of which ~60% in the US), and €3.6 billion in Electricity Networks.
Reiterate EBITDA at ~€4.9 billion in 2025 gradually increasing to €4.9-5 billion in 2026 and to ~€5.2 billion by 2028 (+6% vs. 2025E), supported by growth in renewables driven by US market, and higher investments in Electricity Networks in Portugal and Spain. Net Debt is expected to stand at ~ €16 billion in 2025 and 2026, reducing by ~€1 billion to ~€15 billion in 2028.
The 2026-2028 business plan reveals EDP's current priorities: the United States remains the primary growth market for renewables, receiving approximately 60% of EDPR's planned investment. Meanwhile, regulated networks in Iberia provide the stable cash flows that underpin the company's credit rating and dividend capacity.
"After 2028, EDP continues to see increase in power demand, enabling accelerated growth in renewables, based on a diversified pipeline and also repricing upside from re-contracting our operational fleet in the U.S.," CEO Miguel Stilwell d'Andrade noted.
IX. Climate Commitments & Sustainability Leadership
Ambitious Decarbonization Targets
EDP expects to be totally coal-free by 2025 and all green by 2030, anticipating its carbon neutral targets by 20 years. EDP's goal is to have more than 50 GW of renewables additions before 2030, moving production from 74% renewables as of today, to 100% in 2030.
EDP has committed to achieving net zero by 2040.
These targets position EDP among the most aggressive decarbonizers in the global utility sector. While many peers aim for net-zero by 2050 (aligned with Paris Agreement timelines), EDP has committed to 2040—a full decade earlier.
Carbon neutral by 2030. The pace of climate change is worrying. EDP is determined to contribute to reversing this direction.
Current Renewable Mix
Presently, over 85% of EDP's energy is generated from renewable sources.
As of the second quarter of 2023, EDP had a total installed capacity of approximately 26.5 GW, with around 70% of this capacity derived from renewable sources.
This renewable percentage places EDP among the greenest major utilities globally. For comparison, Enel—Europe's largest utility—generates approximately 50% of its electricity from renewables, while Iberdrola approaches 70%. EDP's commitment to 100% renewable generation by 2030 would make it one of the first major integrated utilities to fully decarbonize.
Sustainability Recognition
EDP has been acknowledged by Dow Jones Sustainability Index (DJSI) as the energy company that develops the best sustainability activity worldwide, leading this index among the 103 evaluated enterprises. The company stands out, in addition, as it has been part of this global index for 14 consecutive years.
EDP group has once again been recognized as the world's most sustainable electric utility company by ranking first in the S&P Dow Jones Sustainability Indices (DJSI) World. With a score of 88 out of 100, EDP has outperformed all other electric utility companies and has achieved a rating higher than the industry average.
EDP - EDPR's main shareholder - is a global energy company and a leader in value creation, innovation and sustainability. EDP has been listed on the Dow Jones Index for 14 consecutive years, recently being named the most sustainable electricity company on the Index.
These rankings matter beyond reputational value. Inclusion in sustainability indices drives capital flows from ESG-mandated investors—a rapidly growing segment of institutional capital. EDP's top-tier sustainability positioning provides structural access to green bonds, sustainability-linked loans, and equity investment from funds with environmental mandates.

EDP engages in the generation, transmission, distribution, and supply of electricity in Portugal, Spain, France, Poland, Romania, Italy, Belgium, the United Kingdom, Greece, Colombia, Brazil, North America, and internationally. It operates through Renewables, Networks, and Client Solutions & Energy Management segments. The company primarily generates and sells electricity through hydro, combined-cycle gas turbine, coal, wind, solar, nuclear, and cogeneration sources.
The three-segment structure—Renewables, Networks, Client Solutions—reflects the fundamental economics of the modern utility:
Renewables (via EDPR): The growth engine, characterized by project development, long-term power purchase agreements, and asset rotation. Capital-intensive but benefiting from declining technology costs and favorable policy environments.
Networks: The stability anchor, operating regulated distribution businesses in Portugal, Spain, and Brazil. Returns are set by regulatory frameworks—lower risk but also lower growth.
Client Solutions & Energy Management: The integrated platform, combining retail supply with energy services like storage, efficiency solutions, and electric mobility. Provides customer relationships and market access.
Group Structure
The EDP Group includes EDP Comercial, SU Eletricidade, EDP Produção, EDP Renováveis and E-REDES, all incorporated in Portugal, and EDP Renováveis, incorporated in Spain, EDP's holding company for its renewables business with EDP holding a 71.3% stake.
EDP owns 71% of EDP Renovaveis, the fourth-largest wind power owner/operator in the world.
The partially-listed EDPR subsidiary creates interesting dynamics. Minority shareholders hold 28.7% of EDPR, creating some tension between EDP group optimization and EDPR standalone value maximization. However, the structure provides EDP with currency for future acquisitions (EDPR shares), a public market valuation benchmark for renewable assets, and capital market access separate from the parent company.
Financial Overview
EDP SA successfully delivered or outperformed its 2024 financial guidance, with a recurring EBITDA of EUR5 billion. The company achieved a solid 7% EBITDA growth in electricity networks, supported by strong demand and expansion in Brazil.
Total Revenue: 15,589,151 (TTM); 14,965,762 (FY2024); 16,202,308 (FY2023).
Revenue has stabilized after the extraordinary volatility of 2022 (when European energy prices spiked following Russia's invasion of Ukraine). The current revenue profile reflects more normalized wholesale prices, partially offset by continued growth in renewable generation volumes.
EDP's trailing twelve months (TTM) net profit margin is 5.35%. EDP's total debt-to-equity ratio is 156.18%.
The relatively modest net margin and elevated leverage reflect utility economics: thin margins on regulated activities, significant capital requirements for renewable development, and ongoing investment in grid infrastructure.
XI. Competitive Positioning & Investment Analysis
The European Utility Landscape
The global electricity leaders are headquartered in Europe: France's EDF, Italy's Enel, Germany's E.ON, and Spain's Iberdrola are among the 10 biggest electric utilities in the world based on sales.
Four companies—Enel, Iberdrola, NextEra Energy and Orsted—prioritized the building or buying of clean-power plants when those assets were still considered alternative and expensive. Now they're on the cusp of a breakthrough.
EDP competes—and sometimes partners—with these giants. Iberdrola, with its €150 billion investment plan through 2030, represents the most direct competitor: both companies have strong Iberian positions, both have bet heavily on US renewables, both operate regulated networks alongside generation assets.
Iberdrola has outlined a €150 billion investment plan in the period 2024-2030, with €12bn in 2025 alone. Iberdrola has a significant focus on offshore wind and solar projects.
Enel and Iberdrola have built clean energy capacity in key markets such as the United States and Latin America and are now aiming to have a combined 215 gigawatts of their own renewable capacity by 2030. Other leading green utilities that have also benefited from the shift away from fossil fuels include wind and solar power giant NextEra Energy in the United States and Denmark's offshore wind farm specialist Orsted.
Porter's Five Forces Analysis
Threat of New Entrants: Low to Moderate The utility sector features high barriers to entry—capital requirements, regulatory approvals, grid interconnection queues, and relationships with landowners and communities. However, technology companies (Google, Amazon, Microsoft) are increasingly investing directly in renewable projects, potentially bypassing traditional utility intermediaries.
Bargaining Power of Suppliers: Moderate Wind turbine and solar panel manufacturers have consolidated, with a few players (Vestas, Siemens Gamesa, LONGi, JinkoSolar) dominating supply. However, overcapacity in manufacturing—particularly Chinese solar panels—keeps pricing competitive.
Bargaining Power of Buyers: Moderate Large corporate buyers (tech companies, industrials) increasingly negotiate power purchase agreements directly with developers, putting pressure on margins. Retail customers face switching costs but regulatory pressure keeps retail rates constrained in regulated markets.
Threat of Substitutes: Low but Emerging Distributed solar, battery storage, and energy efficiency can substitute for utility supply. Grid defection remains rare but could accelerate as storage costs decline.
Competitive Rivalry: High European utilities compete intensely for renewable development opportunities, corporate PPAs, and acquisition targets. Scale advantages exist in development capabilities, financing costs, and operational efficiency.
Hamilton Helmer's 7 Powers Framework
Scale Economies: Present in project development (fixed overhead spread across larger portfolios), equipment procurement (volume discounts), and financing (lower cost of capital for larger issuers). EDP benefits but isn't the largest.
Network Effects: Limited in generation; stronger in retail where brand recognition and customer data provide some advantage.
Counter-Positioning: EDP's early commitment to 100% renewables could constitute counter-positioning against incumbents still defending thermal assets. However, most competitors have now adopted similar strategies.
Switching Costs: Moderate for corporate PPAs (contracts create lock-in), limited for retail customers, high for regulated distribution (natural monopolies).
Branding: EDP's sustainability leadership and DJSI recognition provide differentiation in an industry increasingly evaluated on ESG metrics.
Cornered Resource: EDP's US wind development capabilities—built through Horizon acquisition and years of project execution—represent valuable expertise. Land positions for future development provide optionality.
Process Power: Operational excellence in wind farm management, with capacity factors and O&M costs that benchmark well against peers.
The China Question
EDP's Chinese shareholder creates a distinctive risk profile that deserves direct analysis.
Bull Case on CTG: CTG is a patient, long-term shareholder with genuine interest in renewable energy expansion. The partnership provides access to low-cost capital, co-investment capabilities, and potential entry into Asian markets. CTG's presence hasn't prevented EDP from operating successfully in the US for over a decade.
Bear Case on CTG: CTG is a Chinese state enterprise ultimately accountable to the Communist Party. In an environment of US-China decoupling, CFIUS scrutiny of EDP's American operations could intensify. European screening mechanisms could constrain future deals. EDP faces "headline risk" whenever US-China tensions escalate.
CTG's ownership may deter investors, as the sentiment for Europe to decouple from China is not as strong today as it was before the recent political changes in the U.S.
The 25% voting cap provides structural protection against control, but doesn't eliminate the strategic complexities of operating US renewable assets under Chinese minority ownership.
Recent Challenges
The EDPR subsidiary had losses of 556 million euros in 2024 due to abandonment of projects in Colombia, but also to anticipate loss in US offshore due to Trump's orders. One of the first measures adopted by Donald Trump was to halt the public aids to the development of renewable capacity that had been approved in the Inflation Reduction Act package of former president Joe Biden.
These political changes, combined with the volatility in energy prices, rising bond yields, and the uncertainties on public support namely in US, has contributed to the underperformance of the S&P Global Clean Energy Index, which registered a total shareholder return (TSR) of -26%. This has highlighted the challenges faced by pure renewables companies. EDPR's TSR of -45% in 2024 reflects these adverse environment faced by renewables companies in Europe and US.
The 2024 performance illustrates the risks inherent in renewable energy development: policy uncertainty (particularly in the US), project execution challenges (Colombia write-offs), and technology-specific headwinds (offshore wind impairments).
XII. Key Performance Indicators & Valuation Considerations
Critical KPIs to Monitor
1. Renewable Capacity Additions (GW/year)
This metric captures EDP's execution on its growth strategy. The company has targeted approximately 3-4 GW annual additions.
In the last 12 months, EDPR added +1.9 GW in North America, +1.3 GW in Europe, +0.6 GW in South America, and +0.1 GW in APAC. In terms of technology, solar capacity had +2.8 GW additions, onshore wind had +0.4 GW additions, offshore wind +0.4 GW of new additions.
Watch for: Delays in permitting, interconnection bottlenecks, supply chain constraints, or policy changes that slow the pace of additions.
2. Net Debt/EBITDA Ratio
This leverage metric determines EDP's financial flexibility to pursue growth and maintain investment-grade ratings.
Net Debt is expected to stand at ~ €16 billion in 2025 and 2026, reducing by ~€1 billion to ~€15 billion in 2028, strengthening the balance sheet, underpinned by disciplined investment and robust cash flow generation, supporting a solid BBB rating with FFO/Net Debt expected to improve from ~19% in 2025 to ~22% by 2028.
Watch for: Asset rotation proceeds that reduce debt, or conversely, delays that keep leverage elevated.
3. US Renewables Revenue Mix
Given the concentration of growth investment in the US market, this metric captures both opportunity and policy risk exposure.
Watch for: Changes in federal tax credit availability, state renewable portfolio standards, or CFIUS scrutiny that could affect US operations.
Myth vs. Reality
Myth: EDP is a small Portuguese utility. Reality: EDP is a globally diversified renewable energy company with the majority of growth investment occurring in the United States. Portugal represents a shrinking share of total value.
Myth: Chinese ownership means Chinese control. Reality: The 25% voting cap structurally prevents CTG from exercising control regardless of ownership percentage. The 2019 vote demonstrated this protection works.
Myth: Renewable energy companies are immune to economic cycles. Reality: The 2024 performance showed that policy uncertainty, interest rate sensitivity, and execution risk create significant earnings volatility even for "green" companies.
Regulatory and Legal Overhangs
EDP operates in heavily regulated environments across multiple jurisdictions. Key regulatory risks include:
- US Policy Uncertainty: The Trump administration's executive orders affecting offshore wind and IRA tax credits create uncertainty for US renewable investments
- Iberian Regulatory Framework: Distribution returns are set by Spanish and Portuguese regulators; changes to methodology could affect profitability
- Brazilian Regulatory Environment: Currency exposure and regulatory changes create volatility in this significant market
- Portuguese Extraordinary Taxes: Legal appeals are pending regarding taxes imposed during the energy crisis
XIII. Conclusion: The Road Ahead
EDP's transformation—from revolutionary-era state monopoly to global renewable energy leader—represents one of the most remarkable evolutions in European corporate history. The company successfully navigated nationalization, privatization, global expansion, a Chinese strategic partnership, and a hostile takeover attempt, emerging as a credible challenger to industry giants like Iberdrola and Enel.
The next chapter will be determined by execution on the 2026-2028 business plan, particularly in the United States where approximately 60% of renewable investment is targeted. Success requires navigating a complex policy environment, managing interconnection queues and permitting delays, and delivering returns sufficient to fund the next wave of growth.
The Chinese shareholder question remains unresolved. CTG is unlikely to abandon its stake—the investment has been profitable and provides strategic value for China's clean energy ambitions. But the limits imposed by the voting cap create an unusual equilibrium: the largest shareholder can't exercise control, yet any significant transaction requires addressing this structural constraint.
Beyond 2028, EDP expects continued growth opportunities fueled by accelerating power demand from U.S. and European data center development. The company plans to expand through its diversified renewables pipeline, with additional upside from wind repowering, hybridization, and battery storage.
For long-term investors, EDP offers exposure to the energy transition through a company with demonstrable execution capabilities, top-tier sustainability credentials, and a balanced portfolio of growth (renewables) and stability (networks). The discount to larger peers may reflect legitimate concerns about Chinese ownership and policy risk—or it may represent an opportunity to acquire similar assets at a lower valuation.
The company that began with carnations in rifle barrels now places wind turbines across the American heartland. That journey—from revolution to renewable energy leader—offers lessons about patient capital allocation, strategic boldness, and the complex intersection of geopolitics and business strategy. The energy transition will create enormous value over the coming decades. EDP has positioned itself to capture a meaningful share.
