South East Europe is entering one of the most active energy-investment periods in its recent history, combining strong renewable potential with aging conventional assets. The region is also dealing with rising storage needs, grid bottlenecks, energy-security infrastructure, and increasing cross-border integration. This mix is expected to support a dense pipeline of transactions while making investment selection more competitive.
Across the region, investors are increasingly focused on assets that can control grid access, flexibility, customer supply, trading optionality, and contracted cash flows. A project without secured grid connection is treated as a development risk, while assets with secured connection, contracted revenue and storage optionality are positioned as infrastructure-grade. The shift affects how new capacity is valued and financed.
Strategic platforms and early de-risking developers
The strategic utility platform is identified as a likely first winner in the period ahead. PPC is cited as an example through its Evryo acquisition in Romania and its regional solar cooperation with Metlen. Masdar’s acquisition of TERNA Energy is also referenced as global strategic capital scaling through regional platforms across South East Europe and wider Europe.
A second category highlighted for outperformance is developers able to de-risk projects early. While the pipeline in the region is described as abundant, grid-secured, permitted and financeable projects are described as scarce. Developers that can move assets from concept to ready-to-build status are expected to remain valuable partners or acquisition targets.
Bulgaria storage approvals and bankable battery structures
Battery storage is presented as the third likely winner category for 2026–2028. Bulgaria’s approval of support for 82 battery projects totaling around 9.71 GWh is cited as confirmation that storage has moved beyond a niche segment. The approvals point to a broader regional investment class for batteries.
Enery’s 150 MW / 600 MWh Nova Zagora battery is cited as an example of a structure supported by bank financing. The project is also described as using a VPPA framework linked to Vitol, illustrating how credible revenue arrangements can support financing for storage assets.
Turbine OEMs, EPC execution capability, and procurement frameworks
The bankable OEM and EPC supply chain is identified as the fourth winner category. Vestas’ role in Romania’s 461 MW VIFOR wind project and Nordex’s involvement in Serbia’s 154 MW Čibuk 2 wind farm are cited as examples of continued importance for wind bankability. In solar and storage, regional EPCs such as Solarpro and Sunotec are mentioned alongside global suppliers including LONGi and Sungrow.
Auction-backed market frameworks are identified as the fifth winner category. Romania’s CfD program awarding 4.2 GW across two rounds is cited alongside Serbia’s auction allocating up to 645 MW of support. These procurement mechanisms are described as converting policy objectives into projects that can be financed and invested in.
Flexible gas and LNG options alongside transition constraints
Flexible gas and LNG infrastructure is described as the sixth winner category supporting diversification and system reliability. Neptun Deep and Alexandroupolis LNG are cited as remaining strategically relevant due to their role in enhancing regional security of supply and system optionality during a transitioning energy mix.
The likely losers include early-stage pipeline without grid access, where announced projects lacking secured connection capacity are described as being heavily discounted by lenders and buyers. Merchant-only standalone solar in congested markets is also flagged, with capture-price erosion, negative pricing events, and curtailment risk reducing the attractiveness of unhedged exposure unless paired with storage or structured offtake.
Coal-heavy generation risks and sponsor balance-sheet pressure
Coal-heavy generation without a credible transition pathway is cited as another loser category. While coal remains important for system stability in parts of the Western Balkans, it faces constraints tied to carbon costs, financing pressure, regulatory tightening, and CBAM-related risks.
The under-capitalized project sponsor is also highlighted as a loser category for large-scale infrastructure. The period ahead is described as requiring stronger balance sheets, sophisticated financing capability, and credible execution partners, with weak sponsors increasingly pushed toward early exits or valuation discounts.
Megawatts-only valuation versus time- and location-based value
An additional loser category is investors evaluating projects purely in megawatts without accounting for time, location, and flexibility. In the new SEE power system framing referenced here, value depends on hour-level effects including node characteristics, congestion patterns, carbon intensity and system role rather than installed capacity alone.
Deal flow expectations across Romania, Greece, Bulgaria and Serbia
For 2026–2028, expected deal flow includes portfolio consolidation in Romania, Greece and Bulgaria. Other transaction types listed include developer asset rotation, storage platform formation, minority equity investments in renewable platforms, corporate PPA structures, grid and flexibility investments, Serbian auction-backed assets and selective LNG or gas-linked transactions.
Romania is expected to remain among the strongest markets due to CfDs plus large-scale wind and solar potential alongside Hidroelectrica and OMV Petrom participation references including Neptun Deep. Greece is described as remaining the most sophisticated strategic M&A hub driven by PPC, Metlen, Masdar/TERNA Energy, Motor Oil and HELLENiQ Energy.
Bulgaria is identified as a key storage market to watch while Serbia is described as anchoring Western Balkans renewable expansion driven by auctions. The investment focus described across these markets centers on assets that are real, connected, flexible and financeable.
Valuation premiums are referenced for platforms combining operating cash flows with development pipeline strength plus grid access and storage optionality alongside market sophistication.
The next wave of winners in the region is described as not being defined by announced pipeline size but by positioning within future power system architecture.
