Renewable project finance in Southeast Europe is expanding while becoming more selective, with lenders showing greater caution on merchant exposure, grid risk, construction risk and sponsor quality than during the early renewables boom. The financing focus increasingly turns on whether projects can support predictable debt service. Projects with strong sponsors, credible EPCs, grid access and contracted revenues can raise significant debt. Projects with unclear permits, weak offtake or speculative grid assumptions struggle.
Romania solar financing backed by EBRD and commercial lenders
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 project, Slobozia, benefits from a Contract for Difference awarded under Romania’s inaugural CfD auction, while the other two sell into the competitive day-ahead market.
The structure of that financing reflects how contracted and merchant exposure are treated when fundamentals are strong. Lenders are willing to finance a mix of contracted and merchant exposure if sponsor, market and project fundamentals meet underwriting requirements. In that context, the contracted portion is used to anchor the financing. The day-ahead exposure remains part of the revenue mix for two of the projects.
VIFOR wind project expands with Vestas equipment
Rezolv Energy’s VIFOR wind project is highlighted as another benchmark deal in Romania. The second phase includes a 269 MW Vestas order, and the full project is expected to reach 461 MW. The development is described as Romania’s largest wind farm and one of Europe’s largest onshore wind farms. The scale of execution is presented as a key factor for utility-scale delivery.
Larger wind projects require grid capacity, turbine availability, land assembly, permitting discipline and long lead-time financing. The ability to assemble those elements is linked to whether projects can progress through construction and commissioning. The reference to international sponsors, global OEMs and institutional financing is tied to the VIFOR example. It also places emphasis on execution requirements beyond equipment supply.
Čibuk 2 reaches financial close with non-recourse debt
Serbia is also described as becoming more bankable, with Masdar and Taaleri reaching 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. The transaction is positioned as evidence that Western Balkan wind can attract non-recourse commercial debt under defined conditions.
The cited conditions include a strong sponsor group and a credible contractual structure for the project. The reference to repeat infrastructure points to sharing or building around existing grid positions as a way to reduce development risk. By extending from an established wind cluster, Čibuk 2 is presented as benefiting from that infrastructure base. The use of Nordex turbines is included as part of the technology profile in the financing narrative.
Bulgaria battery storage uses virtual PPA structure
In Bulgaria, storage financing is described as changing the conversation around bankability. Enery secured green financing from DSK Bank for its 150 MW / 600 MWh battery storage project in Nova Zagora. The structure includes a virtual PPA involving Vitol. The project is described as one of Bulgaria’s most advanced storage financings.
The source distinguishes storage underwriting from classic renewable finance approaches used for wind or solar. A wind or solar project can be underwritten around forecast production and contracted prices, while a battery depends on spreads, dispatch strategy, balancing markets, degradation, augmentation capex, grid fees and sometimes tolling or virtual offtake. This difference is described as making lender comfort harder to achieve for batteries while still being possible under appropriate structures.
Common bankability elements and role of DFIs
The common features of bankable SEE projects are outlined across sponsor quality, contracting and market arrangements. These include experienced sponsors, bankable OEMs or EPC contractors, documented grid connection and realistic construction timelines. Where available, projects include contracted revenue alongside clear balancing and market-access arrangements. Curtailment and negative-price risk are allocated carefully within these structures.
The role of development finance institutions is described as critical for mobilising commercial capital. EBRD’s loan to PPC for 400 MW of projects in Bulgaria, Greece and Romania benefits from InvestEU support aimed at enabling longer-term funding. EIB’s Western Balkan financing is also referenced as supporting large projects that may otherwise be harder for local markets to fund alone. Together these measures are presented as supporting access to longer-tenor finance.
Hybridization shifts modelling requirements for lenders
The next project-finance challenge identified in the region is hybridization across generation and storage configurations. Lenders are expected to see solar-plus-storage, wind-plus-storage, merchant-plus-CfD and corporate-PPA-plus-market-exposure structures more frequently. These combinations are described as harder to model than single-technology cases while aligning with developments in the power system. The shift points to changing underwriting requirements rather than changes in technology alone.
The standard being applied by lenders is described through a change in question framing over time. Previously, the focus was whether a project could generate electricity; now it is whether it can generate predictable cash flow in a volatile market. That higher standard is presented as what will separate bankable SEE renewables from speculative pipeline activity.
