Abstract(s)
Numa altura em que os preços da energia elétrica estão extremamente elevados e em que os custos energéticos representam uma parte muito significativos dos custos de funcionamento das instituições, torna-se necessário as instalações funcionarem com elevado grau de eficiência energética e terem alternativas ao fornecimento de energia elétrica. É o caso do autoconsumo de energia elétrica. A análise da eficiência energética da instalação e o estudo de produção de energia renovável para autoconsumo, são as atividades necessárias para atingir a fundamental redução de custos e de grande importância também, para a redução do impacto ambiental da instituição. Foi realizado o estado da arte sobre as temáticas enquadradas no tema do trabalho como é o caso da eficiência energética, energias renováveis; autoconsumo e comunidades de energia. Os trabalhos de desenvolvimento realizados foram o estudo da agregação dos contratos de energia
elétrica para redução de custos, a análise de consumos energéticos e desenvolvimento de estudos técnico/económicos de soluções de melhoria da eficiência energética na instalação e estudos técnico/económicos de produção de energia para autoconsumo. Estes estudos têm como objetivo a redução da fatura energética e a redução da dependência da rede pública de fornecimento de energia elétrica.
O presente trabalho foi desenvolvido tendo como instalação e estudo de caso a Fundação de Serralves, localizada no Porto.

This is the case of selfconsumption of electricity. The analysis of the installation's energy efficiency and the study of renewable energy production for self-consumption are the necessary activities to achieve the fundamental cost reduction and of great importance, for the reduction of the institution's environmental impact. The state of the art was carried out on the themes framed in the theme of the work, such as energy efficiency, renewable energies, self-consumption and energy communities. The development work carried out was the study of the aggregation of electricity contracts to reduce costs, the analysis of energy consumption and the development of technical/economic studies of solutions to improve energy efficiency in the installation and technical/economic studies of energy production for self-consumption. These studies aim to reduce the energy bill and reduce dependence on the public electricity supply network. This work was developed using the Serralves Foundation, located in Porto, as its installation and case study.
