Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, whether his Department plans to bring forward legislative proposals to encourage the development of an open market for aggregating and trading behind meter storage in ancillary services markets.

As set out in our Smart Systems and Flexibility Plan, the Government is committed to ensuring that the market for ancillary services becomes more transparent and new technologies and players (including those on the customer side of the meter) are able to compete on a level playing field. Enabling this does not require legislative changes. The System Operator is setting out a roadmap of improvements on transparency and accessibility in ancillary services markets and, through its Power Responsive initiative, supports providers of new business models in accessing ancillary services markets.
