The system, located in Lovech, includes 111 battery containers with lithium iron phosphate devices. It was developed by Advance Green Energy AD, a company owned by brothers Kiril and Georgi Domuschiev. . In 2024, GSL ENERGY completed a 7. 45 MW battery energy storage system (BESS) in Bulgaria, which is used in conjunction with a large-scale solar photovoltaic power plant to provide stable, clean electricity to remote areas. The implementation of this project not only improved the utilization rate of. . A BESS facility of 124. 1 MW in operating power was inaugurated in Lovech in Bulgaria. Located next to a photovoltaic park within Balkan Industrial Park, it is part of the country's first closed licensed power distribution system. However, a new national legislation as well as funds provided through the European Union's Recovery and Resilience Facility could see the country install another 1 GWh over the next two years. 15 billion levs ($675 million) under its EU-funded procurement exercise named RESTORE. The damage is such that r pairs could hardly be made and it will probably be necessary to completely rebuild the power plant.
