The Renewable Heat Incentive Scheme Regulations 2018. Comes into force 21st May. These Regulations are revoke and replace by the Renewable Heat Incentive Scheme Regulations 2011 (SI 2011/2860). These Regulations re-enact the 2011 Regulations with amendments. The premise 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 in connection with the administration of the Scheme.
