In early August 2025, the first phase of the complex energy project of “Tenevo Solar Technologies” was successfully launched, Renalfa IPP, the Vienna-based developer and independent power producer, announced.
The first 69 MW have been put into operation, as well as all connection facilities to the 400 kV ESO grid, with the main supplier of the components for the Siemens Energy. According to the statement, similar facilities have not been built in the country for decades, and their successful launch represents a major step forward in the development of the backbone of the electric grid in southern Bulgaria.
The second phase of the photovoltaic park will be put into operation in early 2026, as some of the panels were damaged by the extremely intense hailstorm that passed through the field in May this year.
The Tenevo project is a hybrid renewable energy complex comprising 238 MW of photovoltaics and a 315 MW / 760 MWh battery energy storage system (BESS). The main creditors of this project are the European Bank for Reconstruction and Development (EBRD) and Raiffeisen Bank International.
Tenevo Solar Technology is a joint venture between Danish Eurowind Energy and Renalfa IPP.
