Solaris Holding, a joint venture between Bulgarian-German solar developer Sunotec and Eurohold Bulgaria, has commissioned its newest hybrid renewable energy facility near Selanovtsi, close to Vratsa in northwestern Bulgaria.
The project covers nearly 38 hectares and includes a 59.8 MW solar power plant with over 103,000 panels, capable of supplying electricity to more than 22,000 homes. It is complemented by a 107.3 MWh battery storage system, which helps balance electricity supply and demand while reducing carbon emissions by approximately 1.03 million tons annually.
Electricity produced at the site will be marketed through Electrohold Trade, the energy trading arm of the Eurohold Group. The project received funding from United Bulgarian Bank and Germany’s Varengold Bank, highlighting strong regional and international financial backing.
This new facility strengthens Solaris Holding’s portfolio, which already includes over 600 MW of installed renewable capacity and more than 2,000 MWh of integrated storage solutions across Bulgaria and neighboring countries. Sunotec, holding a 12% share in Europe’s industrial photovoltaic construction sector, brings extensive experience from over 630 solar projects totaling more than 10 GW.
Last September, Solaris launched another hybrid plant in Pernik, combining a 32 MW solar installation with 61 MWh of storage. The Vratsa facility continues the company’s rapid growth in integrating large-scale solar power with advanced battery technology.
