The wine production process has a high energy demand of about 1,750 million kWh per year in the EU. Saving energy, responsible consumption and efficient use of energy sources are key aspects to consider for the competitiveness and viability of the sector. Therefore, the TESLA project (Transfering Energy Save Laid on Agroindustry), funded by the European Commission, has conducted 39 energy audits in wineries from four countries (Spain, France, Portugal and Italy). The information collected has allowed them to carry out a comparative analysis of energy efficiency measures through a technical-economic study, calculating the period of return on investment and performing a sensitivity analysis to determine the break-even point for each of the investments analysed. The results show that the replacement of chillers by more efficient ones, the installation of variable speed drives on pumps, the introduction of management and control measures such as the implementation of a Building Management System (BMS) and the installation of energy analysers for identification of consumption by use are the measures that have the greatest quantitative impact.
Resumo
Na União Europeia, o consumo anual de energia associado à produção do vinho é de cerca de 1,750 M kWh. A poupança de energia, o consumo responsável e o uso eficiente do recurso energia são aspetos chave a considerar para a competitividade e viabilidade do sector. Deste modo, o projeto TESLA (Transferring Energy Save Laid on Agroindustry), financiado pela Comissão Europeia, realizou 39 auditorias em adegas localizadas em quatro países (Espanha, França, Portugal, Itália). A informação recolhida permitiu realizar um estudo comparativo das medidas de melhoria de eficiência energética do ponto de vista técnico-económico, através do cálculo do período de retorno do investimento e de análise de sensibilidade para determinar o ponto de equilíbrio para cada investimento analisado. Os resultados mostram que a substituição de chillers antigos por outros mais eficientes, a instalação de variadores de velocidade nas bombas e a introdução de medidas de gestão e controlo, tais como: a implementação do sistema de gestão de edifícios e a instalação de analisadores de energia que permitem a identificação do consumo por etapa, são as medidas que apresentam maior impacto do ponto de vista quantitativo.
