RenalfaIPP Inaugurated Hybrid Park with 242 MWp solar and311W / 773 MWh BESS in Bulgaria

Renalfa IPP and Eurowind Energy A/S officially inaugurated the Tenevo hybrid renewable energy complex in South-Eastern Bulgaria, one of the largest hybrid renewable energy platforms in Europe. The complex combines a 242 MWp solar photovoltaic plant with two co-located battery energy storage systems totalling 311 MW / 773 MWh. Tenevo complex is expected to generate approximately 332 GWh of clean electricity a year. Solarpro Holding acted as EPC contractor and project manager for the complex.

The Tenevo complex is financed by European Bank for Reconstruction and Development (EBRD) and Raiffeisen Bank International AG (RBI) with EUR 50 million (US$56.3 million) from EBRD and EUR 53 million (US$59.6 million) from RBI for the PV part and a total of EUR 60 million (US$67.5 million) for the second phase of the BESS, to be signed shortly. The project is among the first in Bulgaria to benefit from a guarantee under the European Union’s InvestEU programme. The PV plant and first phase of BESS in Tenevo are operational since 2025.

Following Renalfa’s and Eurowind Energy’s strategy for maximizing the available grid connection by hybridization of generating assets, the Tenevo complex is designed to strengthen grid resilience, enable higher shares of renewable energy in Bulgaria's power system, and deliver reliable, flexible, market-oriented clean power. The platform is set to expand further, with planned wind phases of more than 250 MW. Across all phases, total investment in Tenevo is expected to exceed EUR 500 million (US$562.9 million).
