Design of energy communities with photovoltaic in North of Spain

ABSTRACT

European Union promoted the concept of collective self-consumption and the so-called energy communities, to involve citizens in energy management and to improve energy efficiency. In accordance, this work incorporates energy communities including public residential buildings in a city of the north of Spain to identify the possibilities of energy communities based on Photovoltaic energy systems, and to analyze their feasibility for self-production. In addition, the possibility of including a rooftop of a factory is studied to supply the complete electric demand. An economic analysis gives a 2 years payback, and an environmental analysis shows that this installation would save almost 1,600 tons/y of CO2.
