Watt Power has been seeking to develop a portfolio of small, flexible power projects to support the security of electricity supply in England and Wales since 2012.  The principle focus of these efforts has centred on the development of two 300MW gas-fired generation projects in wholly-owned subsidiary companies Progress Power and Hirwaun Power.  These projects participated in the 2015 Capacity Market Auction but were unsuccessful in securing contracts.

Watt Power’s subsidiary company, Prime Energy, has focused on small-scale distributed generation projects.  Seven Prime Energy projects were successful in the 2015 Capacity Market Auction, and subject to their raising construction finance, are targeted to be built in time to meet their Capacity Mechanism commitment in 2019, at the latest.  Each 20MW project will provide short-run back-up generation to the Grid, at times when electricity demand is at its highest – normally during winter weekday evenings.
