Benefit and impact of energy system aggregation

During the last years, the development of photovoltaics (PV) has favored the creation of solar projects around the world. Nowadays, the majority of PV owners manage their energy independently. However, aggregation of consumers in communities could lead to higher PV self-consumption and thus reduced electricity levelized cost and payback time. This report studies the benefits for the communities according to the level of aggregation. Besides, this report evaluates the impact of the aggregation of the demand, generation and potential flexibility (storage) on the reduction of the operating costs. The results show that the aggregation of a community increases its self-consumption and self sufficiency by almost 10% each. It also increases profits and divides by 2 the duration necessary to the repayment of the investment compared to a non-aggregated community, thus passing to 6.5 years.
