As South-East Europe approaches 2025, the landscape of renewable energy ownership is shifting significantly, moving away from traditional state utility dominance. While hydropower assets constructed prior to 1990 remain predominantly under public ownership, the recent surge in wind and solar installations has seen a majority of these assets acquired by private investors, international utilities, infrastructure funds, and development banks. Notably, Gulf sovereign-linked capital is increasingly becoming a key player in this evolving market.
Greece exemplifies the maturation of this transition. The Greek government continues to play a vital role through PPC Renewables, which manages a substantial renewable portfolio that includes wind, solar, and small hydro projects. However, the market has also attracted numerous strategic private entities. Major industrial groups and European energy utilities now control large renewable platforms, often financed through project companies that blend strategic operational management with long-term investments focused on stable cash flows. This multi-faceted ownership environment features a mix of state interests, private Greek capital, European energy firms, and Middle Eastern investors.
In Romania and Bulgaria, similar patterns emerge but with distinct industrial contexts. Romania’s renewable sector is characterized by a combination of robust state involvement in hydro and nuclear power alongside privately owned utilities and major European energy companies diversifying into renewables. Recent years have seen significant transactions where large solar and wind projects have been sold to strategic buyers and infrastructure funds capable of developing these assets further. Bulgaria mirrors this trend with its utility-scale projects primarily backed by international sponsors and financial investors who are comfortable engaging in merchant markets and corporate power purchase agreements (PPAs).
The Western Balkans present a clearer picture of the ownership landscape: while hydropower remains largely public, other renewable sources are predominantly privately or foreign-owned. State utilities such as EPS in Serbia and EPCG in Montenegro continue to manage legacy hydropower assets. However, independent power producers—often supported by European developers or foreign investment—are now driving the development of wind farms and solar plants across the region. These entities typically partner with local conglomerates or infrastructure investment funds targeting long-term yields.
Serbia serves as a crucial case study within this framework. The initial commercial wind developments were spearheaded by private sponsors leveraging both Italian expertise and local capital. As Serbia’s renewable auction process unfolded, it became evident that most bidders were private developers rather than state entities. Although EPS is beginning to engage more actively in wind and solar projects, the primary growth has been fueled by private investments. Financing for these initiatives often involves collaborations between local European banks and development finance institutions while equity stakes are held by specialized investors.
The financing structure across North Macedonia, Bosnia and Herzegovina, Albania, and Montenegro reflects similar trends. Legacy hydro assets remain on state balance sheets while new renewable capacity is predominantly controlled by foreign independents or joint ventures between domestic firms and international partners. Many projects are financed through non-recourse or limited-recourse structures that allow banks to underwrite developments effectively while minimizing risk exposure for sponsors. This reliance on external financing underscores the pivotal role played by Western European banks and international financial institutions as they facilitate project progression from conception to grid connection.
A critical layer exists above project-level financing involving international development banks and European financial institutions that have emerged as key financiers for renewables in South-East Europe. They provide long-term debt options that commercial banks typically shy away from alone while simultaneously de-risking early project pipelines for institutional investors’ participation. Large infrastructure funds have also begun acquiring operating portfolios or co-investing in specific projects alongside strategic utilities—a trend that signals a shift towards treating power plants as long-term yield-generating assets rather than mere engineering accomplishments.
A notable influx of capital from Gulf sovereign-linked developers further complicates this landscape as they establish significant positions within major South-East European renewable platforms. Their long-term investment strategies focus on multi-gigawatt developments rather than isolated projects, enhancing regional integration efforts but also raising concerns about local economic benefits being siphoned off abroad unless domestic stakeholders enhance their competitive capabilities.
Simplifying the ownership dynamics reveals several key structural realities for 2025: First, large hydropower facilities remain under state control; second, most significant wind parks and industrial-scale solar projects are foreign-owned or financed through international channels; third, development banks along with large infrastructure funds are instrumental decision-makers due to their pivotal role in financing renewable expansion across the region.
The combined portfolio weight of EU utilities, industrial energy firms from Europe, private renewable developers, institutional investors backed by infrastructure funds from the Gulf region alongside domestic conglomerates indicates that these entities collectively dominate new renewable capacity ownership in South-East Europe. State utilities are gradually entering this arena but lag behind their private counterparts regarding speed of execution and financial capacity—resulting in cash flows from tariffs and electricity sales likely flowing towards these international owners over the next two decades unless local actors can accelerate their equity participation.
This evolving ownership structure presents dual implications for policymakers: it has facilitated an increase in renewable capacity beyond what local capital markets could achieve independently while also externalizing a significant portion of future income streams derived from renewables. The pressing challenge for South-East Europe lies not merely in generating additional renewable energy but ensuring that these resources are increasingly owned within its borders to retain financial benefits locally.
