Renalfa IPP and Eurowind Energy have opened the latest phase of Bulgaria’s Tenevo renewable energy complex, combining 242 MW of solar capacity with 311 MW/773 MWh of battery storage.
The solar plant is expected to produce about 332 GWh annually. More than 250 MW of wind capacity is also planned, with total investment expected to exceed €500 million if all phases are completed.
The solar plant and first battery phase have operated since 2025. The additional storage increases the project’s ability to shift electricity sales away from periods of concentrated solar production.
Solarpro Holding handled engineering, procurement, construction and project management.
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, supporting a project whose commercial performance increasingly depends on flexible delivery rather than solar generation alone.
