Renewable Energy Communities (RECs) enable the collective organization of consumers
and producers in physical proximity, allowing for self-consumption or the creation of a
legal entity such as a cooperative. Both approaches offer economic, social, and
environmental benefits.
Introduced by the RED II Directive and transposed into Portuguese law by Decree-Law
No. 162/2019, updated by Regulation 2/2023, RECs promote the decentralized
production of renewable electricity, aligning with the National Energy and Climate Plan
2030.
This dissertation analyzes two RECs: one at the University of Évora and another at the
Humanitarian Center of Évora of the Portuguese Red Cross. For this purpose, an energy
and economic simulation model was developed, aiming to optimize self-consumption and
reduce electricity costs.
At the University of Évora, where historical center restrictions prevent the installation of
photovoltaic panels, the six photovoltaic systems, with a total installed capacity of 601,38
kWp, operating under a collective self-consumption regime, will reduce annual
consumption by 801 MWh, with an overall self-consumption rate of approximately 94%.
This will result in savings of €362 304,30, representing a 22,22% reduction in electricity
costs. At the Humanitarian Center, a 30 kWp photovoltaic system is expected to produce
42 MWh annually, with a self-consumption rate of 38,09%, contributing to cost
reductions and CO₂ emissions mitigation.
