A major solar power facility in southern Bulgaria has expanded into hybrid renewable energy generation following the launch of a large-scale battery storage system developed through cooperation between Eurohold Bulgaria and renewable energy company 360 Energy.
The newly commissioned battery energy storage system, delivered by ESCO Bulgaria, adds 36 MW of power capacity and 72 MWh of storage capability to the Maglizh solar project. The upgrade allows the facility to combine photovoltaic electricity generation with advanced energy storage, improving operational flexibility and integration with the national electricity network.
Located near the village of Dabovo in the Stara Zagora region, the Maglizh complex already operates a solar plant with an installed capacity of 161 MW. The project is jointly owned by 360 Energy and Solaris Energy, a company connected to the principal shareholders of Eurohold Bulgaria.
The solar power plant officially entered commercial operation in September 2025 and is connected to Bulgaria’s national transmission network through operator ESO. According to project developers, the facility is expected to generate enough electricity annually to supply more than 65,000 households.
Developers also estimate that the renewable energy complex will reduce carbon dioxide emissions by approximately 200,000 tons per year, contributing to Bulgaria’s climate and clean energy objectives.
Financing for the project was secured through a consortium of banks including UBB, Ascory Bank, Raiffeisen International Bank, Bulgarian Postbank and UniCredit Bulbank. Additional financial support was provided through Bulgaria’s National Recovery and Resilience Plan.
The integration of large-scale battery technology reflects a broader European energy trend, as renewable energy developers increasingly combine solar and wind generation with storage systems to improve energy balancing, enhance grid stability and strengthen electricity network reliability.
