Greenvolt has secured over €58m in project finance from Unicredit Bank Hungary for the 99MW/288MWh Buj battery energy storage scheme.
The company said the facilities will support construction, operation and maintenance of the standalone project in Szabolcs-Szatmár-Bereg County.
It added that the BESS is under construction and due for completion in the first quarter of 2026.
“Battery storage is already an essential pillar of modern energy systems, providing the flexibility and resilience needed to support the growing share of renewables,” said João Manso Neto, CEO of the Greenvolt Group.
“This financing reinforces Greenvolt’s strategy to scale up storage assets across key European markets and strengthens our position in a segment that is increasingly central to the energy transition,” Neto added.
“I strongly believe that Europe’s strength lies in sustainable and predictable energy sources, and I am proud that our Group’s commitment enables us to play an active role in driving this progress,” stated Balázs Toldi, head of corporates division at Unicredit Bank Hungary.
“The financing of Greenvolt’s landmark Buj project demonstrates Unicredit Bank commitment to supporting Hungary’s energy transition and to driving innovation in sustainable financing,” said László Lakos, director of structured finance at Unicredit Bank Hungary.
“Our teams, together with the highly experienced professionals at Unicredit Bank Hungary, worked closely to structure a tailored project finance solution that meets the needs of both parties,” said Adrian Góralski, director of M&A and project finance at Greenvolt Power.
