A government response published on 5th November 2026 sets out unresolved questions about emerging technologies in the Capacity Market.
Current position
Three submissions addressed geothermal electricity, ammonia-to-power and offshore hybrid assets. The department will continue examining technical evidence and classification with the National Energy System Operator. The original consultation opened on 2nd September; the November response is the new milestone.
Why this matters
Developers should retain uncertainty around eligibility and future auction income. The response does not establish that each technology has gained a new generating class or secured a contract.
Next steps
Watch for subsequent rules and assessments. The next annual open letter is planned for autumn 2027.
