These Regulations establish the Green Gas Support Scheme (GGSS) which is a scheme to facilitate and encourage renewable generation of heat by the production of biomethane by anaerobic digestion for injection into the gas grid, thereby helping to decarbonise UK gas suppliers by increasing the proportion of “green” gas. The scheme provides support for biomethane producers through a tariff based mechanism, and is funded by levy payments collected from licensed gas suppliers. The new Regulations will mean the new GGSS and Green Gas Levy (GGL) can launch and will allow a levy to be collected from fossil fuel gas suppliers to fund support payments to biomethane producers through the GGSS. The GGSS replaces the Renewable Heat Incentive (RHI) Scheme, set out in the Renewable Heat Incentive Scheme Regulations 2018, which closed to new applicants, on 31 March 2021.
