PORTUGAL: An automatic demand response system involving air conditioning and cold storage now under test in Lisbon could become a model for other European cities.
The Japanese/Portuguese project has multi-split air conditioning systems and cold storage systems installed in four public buildings, including Lisbon City Hall. During the demonstration, the upper limit of electricity consumption for the air conditioning system will be automatically controlled in response to the needs of the grid.
The project, which started this month, is planned to continue through to the end of 2019. It involves co-operation between Japan’s New Energy and Industrial Technology Development Organisation (NEDO), Portugal’s National Energy and Geology Laboratory, Daikin Industries, local electric power retailers and virtual power plant (VPP) operators.
Based on the results of this demonstration project, Daikin Industries aims to develop an air conditioning automatic demand response system in Portugal and other European regions.
Portugal is a leader in the introduction of renewable energy such as wind power generation and hydroelectric power generation. Portugal’s average renewable generation for the month of March exceeded 103% of consumption and the country is predicting that renewables will satisfy its mainland electricity needs by 2040. However, its renewable energy can be unpredictable, so Portugal still currently needs fossil fuels to even out supply.
