South East Europe is entering one of the most active periods for energy investment 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 mix is expected to support a high volume of deals while also increasing selectivity among investors.
Across the region, investor focus is shifting toward assets that can manage grid access, provide flexibility, support customer supply, enable trading optionality and deliver contracted cash flows. Projects without secured grid connection are increasingly treated as higher development risk. Assets with secured connection, contracted revenue and storage optionality are positioned as infrastructure rather than standalone generation.
Strategic utilities and early de-risking developers
One category of likely winners is strategic regional utility platforms. 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 a case of global strategic capital scaling through regional platforms across South East Europe and wider Europe.
A second winner set includes developers able to de-risk projects early. While the pipeline in the region is described as abundant, grid-secured, permitted and 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.
Bulgaria’s battery pipeline and bankable storage structures
Battery storage is highlighted as a key winner for 2026–2028. Bulgaria’s approval of support for 82 battery projects totaling around 9.71 GWh is presented as evidence that storage has moved beyond a niche segment. The approvals are framed as part of a broader regional shift toward investable flexibility assets.
Enery’s 150 MW / 600 MWh Nova Zagora battery is cited as a financing example. The project is described as backed by bank financing and structured around a VPPA linked to Vitol. The reference links storage financeability to credible revenue frameworks.
Turbine OEMs, EPC execution and supply chain bankability
The bankable OEM and EPC supply chain is identified as another winner area. Vestas’ role in Romania’s 461 MW VIFOR wind project and Nordex’s involvement in Serbia’s 154 MW Čibuk 2 wind farm are used to illustrate continued demand for global turbine suppliers in wind bankability.
For solar and storage execution, regional EPCs including Solarpro and Sunotec are mentioned alongside global suppliers such as LONGi and Sungrow. The focus of these references is on execution capability for projects moving through permitting and financing stages.
CfDs, auctions and gas-linked infrastructure
A further winner category is auction-backed market frameworks that convert policy goals into financeable projects. 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 presented as central to project bankability.
Flexible gas and LNG infrastructure is also highlighted as relevant for diversification and system reliability. Neptun Deep and Alexandroupolis LNG are referenced as projects supporting regional security of supply and system optionality during a transitioning energy mix.
Projects discounted by grid risk, merchant exposure and sponsor weakness
The outlook also identifies likely losers within the same transition dynamics. Early-stage pipeline without grid access is described as being heavily discounted by both lenders and buyers when connection capacity is not secured.
Merchant-only standalone solar in congested markets is another loser category discussed. Capture-price erosion, negative pricing events and curtailment risk are cited as factors reducing the attractiveness of unhedged exposure unless paired with storage or structured offtake arrangements.
Coal-heavy generation without a credible transition pathway is also flagged. In parts of the Western Balkans where coal remains important for stability, constraints are described as coming from carbon costs, financing pressure, regulatory tightening and CBAM-related risks.
The under-capitalized project sponsor is identified as a further weak point for large-scale infrastructure delivery. The requirements described include stronger balance sheets, sophisticated financing capability and credible execution partners, with weaker sponsors facing early exits or valuation discounts.
An additional loser category involves investors evaluating projects only by megawatts rather than by time, location and flexibility. In the described SEE power system context, value is said to be determined by hour, node, congestion, carbon intensity and system role rather than installed capacity alone.
Deal flow themes across Romania, Greece, Bulgaria and Serbia
For 2026–2028, the most likely deal flow includes portfolio consolidation in Romania, Greece and Bulgaria. Other referenced themes include developer asset rotation, storage platform formation, minority equity investments in renewable platforms and corporate PPA structures.
The deal flow also includes grid and flexibility investments alongside Serbian auction-backed assets. Selective LNG and gas-linked transactions are referenced as part of the expected activity mix across the region.
Romania is expected to remain among the strongest markets due to CfDs, large-scale wind and solar potential plus named stakeholders including Hidroelectrica and OMV Petrom alongside Neptun Deep and mature project finance structures. Greece is described as the most sophisticated strategic M&A hub with PPC, Metlen, Masdar/TERNA Energy, Motor Oil and HELLENiQ Energy driving activity.
Bulgaria is identified as the key storage market to watch while Serbia is described as anchoring Western Balkans renewable expansion through auction-driven support mechanisms.
From megawatts to platforms within integrated regional systems
The investment conclusion presented emphasizes that South East Europe remains highly investable but structurally complex. Capital concentration is described around assets that are real, connected, flexible and financeable.
Valuation premiums are described as going to platforms combining operating cash flows with development pipeline depth plus grid access and storage optionality alongside market sophistication. The next wave of winners is stated to be defined by positioning inside future power system architecture rather than by announced pipeline size alone.
The SEE energy story for 2026–2028 is framed around a transition from megawatts to platforms, from generation to flexibility and from standalone projects to integrated regional energy systems.
