DESNZ consult on GGSS Mid-Scheme Review – more information to follow!

The Mid-Scheme Review of the Green Gas Support Scheme (GGSS) was launched today (23 March 2023) by the Department for Energy Security and Net Zero (DESNZ). The consultation will run for eight weeks till 18 May.

The mid-scheme review seeks views on a number of topics, including:

  • A proposed extension to the scheme to March 2026
  • Proposals for the maintenance of the current tariff guarantee deadlines
  • Proposals to maintain the current commissioning deadline
  • Proposals to retain the current waste feedstock threshold, which is currently set at 50%
  • The continuation of current requirements for digestate management
  • Evidence on methane leakages and measures to mitigate leakage from GGSS plants
  • Eligibility criteria for conversions of CHPs to biomethane under the scheme and a call for more detailed information on conversion and decommissioning costs
  • Views for a future biomethane policy framework

Chris Huhne, Chairman of the Anaerobic Digestion and Bioresources Association (ADBA), commented:

While ADBA welcomes some of the proposals such as the continuation of the 50% waste feedstock thresholds and the extension to the scheme, proposals to not allow for the conversion of CHPs come as a potential blow to some areas of the sector.

The review is calling for views from the developers, operators, and other stakeholders in the anaerobic digestion sector.  Our policy team is working on a comprehensive brief on the Review, which will be published shortly. We will also be conducting outreach in order to gather evidence and coordinate our response to the Review.

In the meantime, please email to provide feedback and raise your concerns regarding the Green Gas Support Scheme.
