Enery Development GmbH (Enery) and OMV Petrom S.A. (OMV Petrom) have formed a joint venture to build and operate the Gabare photovoltaic project. The project will have an installed capacity of 400 MW and is situated in northwest Bulgaria. The project is designed for the potential integration of a battery energy storage system of up to 600 MWh.
The two companies plan to invest approximately €200 million in this venture by 2027, including own equity and external financing. Furthermore, the final investment decision for the project is expected by the end of 2025. Commercial operations are expected to commence in 2027. As part of this partnership, OMV Petrom will enter into a 10 year power purchase agreement to secure approximately half of the electricity produced by the project.
Earlier in June 2025, Enery commissioned the 9 MW/18 MWh Rummu battery energy storage system. The project is situated in Harju County and became operational in September 2023. The facility is engineered to handle high-frequency charge and discharge cycles with seamless responsiveness.
