Strategic buyers are becoming the dominant force in South East European energy M&A. Infrastructure funds remain active, developers still rotate assets, and banks still finance projects. But the most important buyers are increasingly utilities and integrated energy groups that can use assets across generation, supply, trading and customer platforms.
This is happening because SEE electricity markets are becoming more complex. Renewable generation is growing, but so are grid constraints, negative-price risk, balancing costs, storage needs and cross-border volatility. In that environment, a standalone asset owner may capture only part of the value. An integrated utility can capture more.
PPC is the clearest example. The Greek utility has moved aggressively into regional renewables, including its acquisition of Evryo’s Romanian portfolio. That deal added 629 MW of operating renewables, mostly onshore wind, and about 145 MW of pipeline assets. PPC described the transaction as part of its strategy to strengthen its Southeast Europe position.
The strategic logic is obvious. PPC can use Romanian wind to diversify away from a Greece-only generation base, balance its regional portfolio and support its wider transition from legacy utility to South East European power platform.
Its cooperation with Metlen expands that logic. PPC and Metlen agreed on a framework for up to 2 GW of solar projects across Italy, Romania, Bulgaria and Croatia. Metlen develops and constructs the projects; PPC acquires them after grid connection.
This kind of arrangement reflects a new division of labor. Developers with EPC capability can originate and build. Utilities with balance sheets and customer bases can own and integrate. The result is faster capital recycling for developers and more controlled growth for strategic buyers.
Masdar’s acquisition of TERNA Energy is another defining transaction. The deal valued TERNA Energy at around €3.2 billion enterprise value, with the company operating around 1.2 GW and targeting 6 GW by 2029.
Masdar’s logic is different from PPC’s, but the platform idea is the same. TERNA Energy gives Masdar a strong European renewables base, a Greek anchor, a development pipeline and exposure to strategic assets such as pumped hydro. For a global renewable investor, Greece is not just a local market; it is an entry point into Southeast Europe and the wider European power transition.
Metlen is also important because it combines project development, EPC capability, energy trading and industrial depth. That makes it a different kind of player from pure developers. In a market where bankability depends on execution, EPC strength and energy-market sophistication, integrated groups can create value across the chain.
Other regional players follow similar logic. OMV Petrom is central in Romania because it combines oil and gas, power, offshore gas and transition investment. Romgaz is strategically important through its role in Neptun Deep. Hidroelectrica gives Romania a large listed renewable utility with hydropower dominance. HELLENiQ Energy and Motor Oil are pushing into renewables as part of broader energy-transition strategies.
Financial sponsors are not absent. Macquarie, Asterion, Actis, Taaleri, Mirova and other infrastructure investors remain important. But their role is increasingly linked to platform formation, asset rotation and minority or majority stakes in de-risked portfolios.
Asterion’s purchase of 50% of TotalEnergies’ 424 MW Greek portfolio is a good example of infrastructure capital entering an operating renewables position at a clear valuation benchmark of about €1.2 million per MW. Principia, the Enel-Macquarie platform, acquired EDPR’s 150 MW Greek wind portfolio, showing how financial and strategic capital can combine in asset rotation.
Why are strategics often advantaged?
First, they can take merchant and balancing risk that pure financial buyers may price cautiously. Second, they can use renewable output to serve retail or corporate customers. Third, they may have trading desks capable of managing shape risk. Fourth, they can combine generation with batteries, supply, PPAs and cross-border optimization. Fifth, they often have better access to corporate debt and green bonds.
This matters for sellers. A developer selling a de-risked project may receive better value from a strategic buyer if the asset fits a portfolio need. A financial buyer may focus more tightly on contracted yield, downside protection and leverage capacity.
For the next cycle, expect three types of strategic consolidation.
First, utilities will buy operating renewables to secure clean generation and reduce portfolio carbon intensity. Second, integrated groups will use development partnerships to build cross-border portfolios. Third, global capital will acquire regional platforms rather than assembling projects one by one.
South East Europe is fragmented enough to offer opportunity, but integrated enough to reward scale. That is exactly the environment where strategic buyers matter most.
The market is moving from project ownership to portfolio control. In SEE energy, the best buyers are not just buying assets. They are building regional operating systems.
