HOUSING | SMART GRIDS Domestic battery storage can offer some flexibility in matching the demand profile of a home with the Grid and with onsite generation, as bere:architects successfully demonstrated with Lark Rise. But, currently, domestic-scale batteries are expensive. One solution to providing battery storage particularly for new developments with multiple homes is community battery for energy storage, a concept being trialled at the Trent Basin housing scheme in Nottingham. The scale of its battery installation enables it to supply or absorb power from the National Grid under a frequencyresponse-type contract, which in the case of Trent Basin is, potentially, a significant revenue driver, and a means of helping to offset the cost of the battery system. (See article Battery packs a punch in January 2018 CIBSE Journal). The growth of electric vehicles could, however, mean they are part of the solution rather than being part of the problem. There could be 1TWh of electric storage in vehicle batteries by 2035, says Evans, who Greater EV uptake is likely to result in an increase in peak electrical demand believes it would be a game changer particularly when 100GWh of battery storage will allow the whole of the UK to be powered offGrid for a couple of hours. (See panel, Mobile batteries) Lark Rise this years CIBSE Building Performance Awards Residential Project of the Year is, perhaps, a foretaste of how all new homes might be designed to work with a Grid powered by renewable energy. It shows that, with creative design, it is possible to mitigate demand on the UK electrical infrastructure and after Chancellor Philip Hammonds announcement, in his Spring Statement, that gas heating is to be banned in new houses from 2025, it might prove to be a benchmark for all new homes.
