Renewable project finance in South East Europe is expanding, but lenders are applying tighter conditions than during the early renewables boom. Financing is available for wind, solar and storage, while attention is focused on merchant exposure, grid risk, construction risk and sponsor quality. Projects are assessed on whether they can support debt under the expected power-market and delivery profile.
Lenders are more willing to raise significant debt when sponsors are strong, EPC arrangements are credible, grid access is in place and revenues are contracted. Projects with unclear permits, weak offtake or assumptions about grid performance that are not supported face greater difficulty accessing financing. This creates a divide between bankable projects and speculative pipeline.
Romania’s solar financing package and market structures
Romania is described as one of the most important project-finance markets in the region. EBRD arranged a €192 million financing package for three solar plants totaling 531 MW in southeastern Romania. EBRD provided €64 million for its own account and mobilized €128 million from commercial lenders.
One of the projects, Slobozia, benefits from a Contract for Difference awarded under Romania’s inaugural CfD auction. The other two plants sell into the competitive day-ahead market. The mix of contracted and merchant exposure is linked to sponsor, market and project fundamentals.
Romania wind benchmark: VIFOR scale and delivery requirements
Rezolv Energy’s VIFOR wind project is presented as another benchmark for Romania’s renewables financing. The second phase included a 269 MW Vestas order, with the full project expected to reach 461 MW. The development is described as Romania’s largest wind farm and one of Europe’s largest onshore wind projects.
The VIFOR example highlights execution scale requirements alongside financing access. Big wind projects require grid capacity, turbine availability, land assembly, permitting discipline and long lead-time financing. These elements affect how lenders assess construction risk and delivery timelines.
Serbia wind financial close: Čibuk 2 debt terms
Serbia is also moving toward greater bankability for renewable projects. Masdar and Taaleri reached financial close on the 154 MW Čibuk 2 wind farm. The deal includes a €144 million non-recourse debt facility from UniCredit and Erste.
The project uses Nordex turbines and builds on the existing Čibuk wind cluster. Čibuk 2 is cited as evidence that Western Balkan wind can attract non-recourse commercial debt when the sponsor group is strong and the contractual structure is credible. It also points to repeat infrastructure through sharing or building around existing grid positions to reduce development risk.
Bulgaria storage deal: Nova Zagora battery with virtual PPA
In Bulgaria, battery storage is changing how projects are financed. Enery secured green financing from DSK Bank for its 150 MW / 600 MWh battery storage project in Nova Zagora. The structure uses a virtual PPA involving Vitol.
The Nova Zagora transaction is described as one of Bulgaria’s most advanced storage financings. Storage finance differs from classic renewable underwriting because batteries depend on spreads, dispatch strategy, balancing markets, degradation, augmentation capex, grid fees and sometimes tolling or virtual offtake. Lender comfort can therefore be harder to achieve than for forecast-based generation models tied to contracted prices.
Common bankability features supported by DFIs
The common features of bankable SEE renewable projects are becoming clearer across markets. They include experienced sponsors, bankable OEMs or EPC contractors, documented grid connection and realistic construction timelines. Where available, projects also include contracted revenue and clear balancing and market-access arrangements.
Lenders also focus on how curtailment and negative-price risk are allocated within deal structures. Projects are often supported by DFIs, EU guarantees or national schemes. DFIs are described as critical because they help crowd in commercial banks.
EBRD’s loan to PPC for 400 MW of projects in Bulgaria, Greece and Romania benefits from InvestEU support to enable longer-term funding. EIB’s Western Balkan financing similarly supports large projects that may be harder for local markets to fund alone. This approach aligns with the broader preference for predictable cash flows backed by defined risk allocation.
Hybridization as the next modeling challenge for lenders
The next project-finance challenge identified in the region is hybridization. Lenders increasingly expect structures such as solar-plus-storage, wind-plus-storage, merchant-plus-CfD and corporate-PPA-plus-market-exposure arrangements. These configurations are described as harder to model while being aligned with changes in the power system.
The shift in underwriting emphasis moves from whether a project can generate electricity to whether it can generate predictable cash flow in a volatile market. That standard is presented as higher than earlier screening questions during previous phases of renewables expansion . It is also framed as a factor separating bankable SEE renewables from speculative pipeline .
