On October 8, 2026, Enery, a leading independent power producer in Central and Eastern Europe, and Coca-Cola HBC Bulgaria EAD, one of the largest beverage producers in the country, have announced signing a long-term physical Power Purchase Agreement (PPA) for the supply of renewable electricity from Enery’s Knizhovnik hybrid power plant in Bulgaria.
Under the agreement, Enery will supply Coca-Cola HBC Bulgaria with locally generated renewable electricity annually based on a fixed solar generation profile.
The agreement marks the second corporate PPA secured for Enery’s Knizhovnik hybrid project, demonstrating how large-scale renewable assets combining solar generation and battery storage can support the different energy needs of major industrial and commercial consumers.
The PPA further supports Coca-Cola HBC’s wider commitment to reducing emissions across its operations and value chain and achieving net zero emissions by 2040. By securing renewable electricity through a long-term PPA, Coca-Cola HBC Bulgaria strengthens the link between its energy procurement strategy and the development of new renewable generation capacity in the country.
The electricity contracted under the PPA will come from Enery’s Knizhovnik hybrid power plant, located near Haskovo in southern Bulgaria. The project combines a 122 MWp photovoltaic power plant with two battery energy storage systems with capacities of 70 MWh and 130 MWh, respectively. The power plants generate approximately 200 GWh of renewable electricity annually, equivalent to the annual electricity consumption of almost 50,000 households.
The integration of battery storage adds flexibility to the project, allowing renewable electricity generation to be managed more efficiently and supporting the wider integration of solar power into Bulgaria’s electricity system.
