A large battery energy storage project in southeastern Bulgaria has reached an important financial milestone after renewables developer Enery secured green financing from DSK Bank, a Bulgarian lender that is part of Hungary’s OTP Group. The funding will support the construction of a utility-scale battery storage facility in the Nova Zagora area.
The project will have an installed capacity of 150 MW and a storage capacity of 600 MWh, making it one of the most advanced battery investments financed in Bulgaria to date. According to Enery, the transaction highlights growing confidence in energy storage as a key pillar of a more flexible power system capable of integrating higher shares of renewable generation.
Construction is progressing toward a planned start of operations in March 2026. The facility will include a dedicated substation and will be connected to a newly built 33/110 kV substation, providing a direct link to the transmission network and enabling full participation in the electricity system.
To strengthen the project’s financial foundations, Enery has also signed a virtual power purchase agreement (PPA) with Swiss-based energy and commodities group Vitol. The agreement is designed to provide predictable long-term revenues and reduce exposure to power market volatility.
Enery is active across Central and Eastern Europe, with a development portfolio approaching 10 GW across ten countries. Its existing renewable assets generate more than 760 GWh of electricity annually, positioning the company as an increasingly significant player in the region’s clean energy transition.
