GGSS Mid-Scheme Review
Ahead of the tariff rate change, DESNZ published the Mid-Scheme Review for the GGSS on 23 March 2023. The consultation will run for eight weeks, addressing a number of items including the waste threshold, digestate mitigation technologies, CHP conversion, methane leakage, sustainability criteria under the GGSS guidance and an opportunity to propose the direction of post-GGSS support. Our analyst team has prepared a comprehensive briefing note that will give you an overview of the contents of the mid-scheme review – Click here to view.
This Mid-Scheme Review seeks stakeholder views on multiple proposals including the scheme’s close date, tariff guarantee and commissioning deadlines, and waste feedstock threshold among others.
Proposals in brief are;
- Extending the GGSS closure date to 31 March 2026
- Maintaining current tariff guarantee deadlines
- Maintaining current commissioning deadlines
- Maintaining the current waste feedstock threshold
- Maintaining GGSS regulations around digestate mitigation requirements
- Maintaining the eligibility criteria of the GGSS to exclude CHP plant conversions to biomethane injection
- Amending regulations related to heat deductions to eligible biomethane to exempt heat produced from heat pumps.
The Review further calls for evidence on;
- Methane leakage monitoring and mitigation practices to understand the GHG emission savings associated with AD and biomethane and to incentivise sustainable production practices
- Options for a post-GGSS policy framework for biomethane
ADBA has reached out to all the members providing an opportunity to feed into the response. We look forward to hearing from you.
