Government has published changes to support rates for renewable and low carbon heat via the Renewable Heat Incentive (RHI).
The department for Business, Energy & Industrial Strategy (BEIS) remains keen to incentivise larger biomass, which it believes is a more efficient use of available funds, and has merged existing tariffs into one rate. The tiered biomass support structure will now favour larger developers.
BEIS has also retained support for non-domestic solar thermal, which was potentially due to be cut when the department consulted on proposed RHI changes earlier this year. However, 92% of responses to that consultation argued against scrapping support.
Subsidy for commercial air and ground source heat pumps remains unchanged, but support for biogas and biomethane will increase, subject to a stricter feedstock requirements.
