Centrica is to absorb thousands of residential hot water tanks into its virtual power plant (VPP) to provide flexibility to the grid. The energy giant has secured approval from National Grid to use the tanks for firm frequency response (FFR) as part of a 2.5GW VPP it is establishing in the UK. The tanks will be provided through a partnership with Mixergy, a spin-off company from the University of Oxford which has previously received investment from Centrica Innovations. The first batch of 100 tanks have already been installed and will be capable of storing energy at times of high renewables, responding at times of stress whilst maintaining efficiency, cost and comfort. The tanks are set to help balance the grid through storing excess load on the grid and time shifting demand. Charles Cameron, chairman of Centrica Innovations, said: "The first batch of 100 hot water tanks, which are now in homes in the UK will, at times of stress, be capable of capturing energy at low market prices on sunny or windy days when there is an abundance of renewables on the network, all whilst maintaining efficiency, cost and comfort for our customers.
