To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment he he has made of the level of demand for (a) home electricity generation and (b) a domestic energy storage unit.
As of September 2018, the Feed-In Tariff scheme had delivered 749,327 household installations with a total generation capacity of 2.8GW. The impact assessment accompanying the consultation and response to the Feed-In Tariff closure provides an assessment of future small-scale low-carbon installations across different capacity sizes, including the 0-10kW band which most household generation falls under.
The Impact Assessment is available at: https://www.gov.uk/government/consultations/feed-in-tariffs-scheme.
As domestic energy storage is a relatively new technology Government does not yet have an assessment of the level of consumer demand. Government will continue to engage with industry bodies and stakeholders to understand how this market is likely to develop.
