Renalfa IPP has completed the repowering and hybridization of another generating asset from its portfolio – the Devnya PV plant in Northeastern Bulgaria. The Devnya PV plant had nominal capacity of 5MWp and has been operating since 2011. After the repowering, the solar park now has an installed capacity of 65 MWp and has been hybridized with a co-located battery energy storage system (BESS) with capacity of 60 MW / 165 MWh. Solarpro Bulgaria acted as Project manager and EPC contractor.

This is yet another of Renalfa IPP’s assets that has been repowered and hybridized following to the company’s strategy for maximizing the available grid connection by co-locating BESS to PV, optimizing the value of the production profile and the sale of green baseload products. In November 2025 Renalfa IPP completed the repowering of its PV park Kaolinovo in Northeast Bulgaria. Project Kaolinovo was repowered from 10 MWp to an installed capacity of 60 MWp and hybridized with a co-located battery energy storage system (BESS) with capacity of 33 MW / 110 MWh.
