These Regulations, which apply in Great Britain, amend the Green Gas Support Scheme Regulations 2021 S.I. 2021/1335 (“the 2021 Regulations”), which established the Green Gas Support Scheme (“the GGSS”). The GGSS is a renewable heat incentive scheme to facilitate and encourage the production of biomethane by anaerobic digestion, for injection into the gas grid. These Regulations make amendments to extend the scheme, providing for a new scheme closure date of 31 March 2028.
