These Regulations, which apply to Great Britain, revoke and replace the Renewable Heat Incentive Scheme Regulations 2011 (the “2011 Regulations”), which established a renewable heat incentive scheme (“the Scheme”). These Regulations re-enact the 2011 Regulations with amendments. The premise of the Scheme remains the same: owners of plants which generate heat from specified renewable sources and meet specified criteria may receive payments at prescribed tariffs for the heat used for eligible purposes. Payments may also be made to biomethane producers who produce biomethane for injection. The Regulations confer functions on the Gas and Electricity Markets Authority (“the Authority”) in connection with the administration of the Scheme.
