South East Europe is entering one of the most active energy-investment periods in its recent history. The region combines strong renewable potential, aging conventional assets, rising storage needs, grid bottlenecks, energy-security infrastructure, and increasing cross-border integration. This is expected to support a dense pipeline of deals, while also making investment screening more selective.
Across the market, investors are increasingly focused on assets that can control grid access, flexibility, customer supply, trading optionality, and contracted cash flows. A megawatt without grid access is described as a development risk. A megawatt with secured connection, contracted revenue, and storage optionality is positioned as a more infrastructure-like asset.
Strategic platforms and early de-risking capabilities
The first likely winner category is the strategic regional utility platform. PPC is cited for its Evryo acquisition in Romania and its regional solar cooperation with Metlen. Masdar’s acquisition of TERNA Energy is also referenced as an example of global strategic capital scaling via regional platforms across South East Europe and wider Europe.
The second winner category is developers able to de-risk projects early. While the region’s pipeline is described as abundant, grid-secured, permitted, financeable projects are characterized as scarce. Developers that can move assets from concept to ready-to-build status are expected to remain valuable partners or acquisition targets.
Storage growth and battery project support
Battery storage is identified as a third winner category. Bulgaria’s approval of support for 82 battery projects totaling around 9.71 GWh is cited as evidence that storage has moved beyond a niche segment. The approval links to the broader shift toward flexibility investments in the region.
Enery’s 150 MW / 600 MWh Nova Zagora battery is referenced as a financing example. The project is described as backed by bank financing and structured through a VPPA linked to Vitol. The case is used to illustrate how storage can be financed when revenue frameworks are credible.
Wind and supply chain bankability
The fourth winner category covers bankable OEM and EPC supply chains. Vestas’ role in Romania’s 461 MW VIFOR wind project is cited alongside Nordex’s involvement in Serbia’s 154 MW Čibuk 2. These examples are used to highlight continued reliance on global turbine OEMs for wind bankability.
For solar and storage execution, regional EPCs such as Solarpro and Sunotec are mentioned together with global suppliers including LONGi and Sungrow. The supply chain mix is presented as an execution anchor for projects moving through development into construction.
Auction-backed frameworks and gas-linked optionality
The fifth winner category focuses on auction-backed market frameworks. Romania’s CfD program awarding 4.2 GW across two rounds is cited alongside Serbia’s auction allocating up to 645 MW of support. Structured procurement mechanisms are described as converting policy goals into financeable, investable projects.
The sixth winner category is flexible gas and LNG infrastructure supporting diversification and system reliability. Neptun Deep and Alexandroupolis LNG are referenced as remaining strategically relevant because they enhance regional security of supply and system optionality during a transitioning energy mix.
Projects facing discounting pressure and sponsor constraints
The likely losers include early-stage pipelines without grid access. Announced projects lacking secured connection capacity are described as being heavily discounted by both lenders and buyers.
A second loser category is merchant-only standalone solar in congested markets. Capture-price erosion, negative pricing events, and curtailment risk are cited as reducing the attractiveness of unhedged exposure unless paired with storage or structured offtake.
A third loser category is coal-heavy generation without a credible transition pathway. Coal is described as still important for system stability in parts of the Western Balkans, but it faces constraints from carbon costs, financing pressure, regulatory tightening, and CBAM-related risks.
A fourth loser category involves under-capitalized project sponsors. Large-scale infrastructure is described as requiring stronger balance sheets, sophisticated financing capability, and credible execution partners; weak sponsors are increasingly pushed toward early exits or valuation discounts.
A fifth loser category targets investors that assess projects purely in megawatts rather than considering time, location, and flexibility. In the SEE power system described here, value is framed as determined by hour, node, congestion, carbon intensity, and system role rather than installed capacity alone.
Deal flow expectations for 2026–2028 by market segment
For 2026–2028, the most likely deal flow includes portfolio consolidation in Romania, Greece, and Bulgaria. Other expected activity includes 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 and gas-linked transactions.
Romania is expected to remain among the strongest markets due to CfDs, large-scale wind and solar potential, Hidroelectrica, OMV Petrom, Neptun Deep, and mature project finance structures. Greece is described as the most sophisticated strategic M&A hub driven by PPC, Metlen, Masdar/TERNA Energy, Motor Oil, and HELLENiQ Energy.
Bulgaria is identified as the key storage market to watch. Serbia is described as anchoring Western Balkans’ auction-driven renewable expansion.
The investment focus described for the period emphasizes capital concentration in assets that are real, connected, flexible, and financeable. Valuation premiums are expected to accrue to platforms combining operating cash flows with development pipeline strength alongside grid access and storage optionality.
The next wave of winners in the region is framed around positioning within the future power system architecture rather than announced pipeline size alone. The SEE energy story for 2026–2028 is characterized as a transition from megawatts to platforms from generation to flexibility , from standalone projects to integrated regional energy systems .
