The Renewable Energy Sources Cluster (RES Cluster) was established on 12 May 2010 in Blagoevgrad. It brings together representatives from business, academia, and non-governmental organisations active in the fields of renewable energy and energy efficiency.
The RES Cluster operates at the national level and maintains offices in Sofia, Blagoevgrad, and Shumen.
Since January 2022, the Cluster has been one of the Bulgarian partners of the Enterprise Europe Network (EEN) – the European Commission’s primary instrument for supporting the innovative and international development of small and medium-sized enterprises (SMEs) across Europe.
