Green Gas Support Scheme (GGSS)
Successor to the Non-Domestic Renewable Heat Incentive (RHI) Scheme. Provides tariff support for plants producing biomethane via anaerobic digestion which is injected into the gas grid. Tariffs are calculated to compensate plants for the building of new infrastructure to produce biomethane and ongoing operation costs.
The Smart export guarantee is a government-backed initiative. The SEG requires some electricity suppliers (SEG Licensees) to pay small-scale generators (SEG Generators) for low-carbon electricity which they export back to the National Grid, providing certain criteria are met.
