Vienna-based independent power producer Renalfa IPP has commissioned the first phase of a large-scale battery energy storage system (BESS) in Bulgaria. The BESS is the first phase of a 315 MW/760 MWh system that is being developed alongside 238 MW of solar under Bulgaria’s largest Tenevo Hybrid Renewable Project, due for completion in 2026.
Located in southeastern Bulgaria, the hybrid project is being developed by Tenevo Solar Technology, a joint venture company between Renalfa IPP and Danish developer Eurowind Energy. Chinese energy storage company Hithium and Chinese power solutions provider Kehua are supplying the BESS technology, while Bulgarian developer Solarpro is acting as project manager.
Once completed, the Tenevo project will encompass a 238 MW solar site alongside the 315 MW/760 MWh BESS and 250 MW of wind turbines. The first phase of the BESS is already one of the largest co-located battery storage systems in Europe and takes its energy storage capacity in operation to in excess of 1 GWh. The project is financed by the European Bank for Reconstruction and Development and Raiffeisen Bank International AG.
