Following the Green Gas Support Scheme (GGSS) Annual Tariff Review (ATR) 2023, the Secretary of State has decided to increase the GGSS Tier 3 tariff from 1.72p/KWh to 3.45p/KWh. The new tariff rate will come into effect on 1 October 2023. Tier 1 and 2 tariffs will remain unchanged.
Tariffs from 1 October 2023 will be:
- Tier 1: up to 60,000 MWh – 6.09p/kWh
- Tier 2: the next 40,000 MWh – 3.90p/kWh
- Tier 3: above 100,000 MWh up to 250,000 MWh – 3.45p/kWh
These tariffs will be applied to tariff guarantees (TGs) awarded to successful applicants whose TG applications are submitted from 1 October 2023 and before the next GGSS tariff change is in effect.
GGSS tariffs are reviewed while the scheme is open to applications through ATRs, published annually by 1 September. They could also be reduced if a degression is triggered by a quarterly Expenditure Forecast Statement. More information is available on the GGSS Budget Management guidance page.
Tariffs will be uprated for inflation on 1 April 2024, using the percentage increase or decrease in the Consumer Price Index (CPI) of the 2023 calendar year.
GGSS tariffs are published online by Ofgem.
