Renalfa IPP and Eurowind Energy have opened the latest phase of Bulgaria’s Tenevo renewable energy complex. The expansion combines 242 MW of solar capacity with 311 MW/773 MWh of battery storage. The project is part of a broader development that also includes additional wind capacity.
Generation profile and planned wind additions
The solar plant is expected to generate about 332 GWh annually. More than 250 MW of wind capacity is also planned as part of the overall complex. Total investment is expected to exceed €500 million if all phases are completed.
Operational status and role of added storage
The solar plant and the first battery phase have been operating since 2025. The additional storage is designed to increase the project’s ability to shift electricity sales away from periods of concentrated solar production. This change relates to how output from the solar component aligns with sales timing.
Engineering, financing and support instruments
Solarpro Holding handled engineering, procurement, construction and project management for the development. Solar financing included €50 million from the EBRD and €53 million from Raiffeisen Bank International. A further €60 million financing package for the second battery phase is expected to be signed shortly.
The development also benefits from an InvestEU guarantee. The guarantee supports a project whose commercial performance increasingly depends on flexible delivery rather than solar generation alone.
