Renalfa IPP and Eurowind Energy launch hybrid power plant in Bulgaria

Renalfa IPP and Eurowind Energy have inaugurated the enlarged Tenevo hybrid renewable energy complex in southeastern Bulgaria. The facility is considered one of the largest of its kind in Europe, combining a 242 MW peak capacity photovoltaic plant with two co-located battery energy storage systems (BESS) totaling 311 MW and 773 MWh.

The project, operated by Tenevo Solar Technologies, is expected to generate approximately 332 GWh of clean electricity annually. Future expansion plans for the site include the addition of more than 250 MW of wind power. Total investment across all phases of the Tenevo complex is projected to exceed EUR 500 million.

Financing for the solar PV component was provided by the European Bank for Reconstruction and Development (EBRD) with EUR 50 million and Raiffeisen Bank International AG (RBI) with EUR 53 million. An additional EUR 60 million in financing for the second phase of the battery storage system is expected to be signed shortly. The project is among the first in Bulgaria to utilize a guarantee under the European Union’s InvestEU programme.
