Greenvolt sells Hungarian solar plant for €64.2 million, launches 200MW storage in Poland

en.Wedoany.com Reported - Greenvolt Power has signed an agreement to sell the Kira photovoltaic plant project in Királyegyháza, southern Hungary, to PPC Group for €64.2 million. The transaction is expected to be completed by the end of 2026, and the agreement includes an option allowing the buyer to acquire the accompanying energy storage project—with a power rating of 49.1 MW and a capacity of 196.2 MWh—once the project reaches Ready-to-Build (RTB) status.

The photovoltaic plant achieved commercial operation (COD) in July 2024 and benefits from a 25-year fixed feed-in tariff under Hungary's KÁT scheme, one of the country's mechanisms supporting renewable energy generation. The project had previously secured €35.5 million in structured project finance.

Once operational, the accompanying storage system will complement solar generation, providing energy arbitrage capabilities, flexibility services, and more efficient use of existing grid connection infrastructure.

Meanwhile, Greenvolt Power has officially launched an energy storage plant in Turośń Kościelna, near Białystok in Poland's Podlaskie Voivodeship. The company stated that the facility has a rated power of 200 MW and a storage capacity of 800 MWh, making it one of the largest battery energy storage systems (BESS) currently in operation in Poland.

The plant connects to the national transmission grid via a 110 kV substation and uses lithium iron phosphate (LFP) batteries.

The facility provides approximately four hours of storage duration. Starting in 2028, it will operate under a 17-year capacity contract, required to deliver 170 MW of capacity, equivalent to 85% of the system's rated power. This mechanism provides an additional revenue stream by compensating for available reliable capacity, independent of actual charge-discharge cycles, thereby enhancing the bankability of large-scale storage projects.
