A key tenet of the European Green Deal (EGD) is to build clean and renewable energy capacity as a key step toward decarbonisation while providing energy security. Planning and implementing the transition to a decarbonized, sustainable, and resilient energy regime is a complex technical, social, political, and economic process. In the case of Armenia, its landlocked and tense geopolitical position in the South Caucasus adds to the complexity of its energy transition efforts. STREACS aims to enhance the research capacity in Armenia to support the country’s efforts to accelerate its energy transition toward clean and renewable energy sources, while enhancing its energy security. Importantly, such enhanced capacity will also enable Armenia to become better integrated into and a more productive actor in the European Research Area. STREACS will facilitate the transfer of knowledge, exchange of best practices, and inclusion in domain-specific academic networks from research institutions and partners in the EU.
