NDRHI closed on 31 March 2023

The Non-Domestic Renewable Heat Incentive (NDRHI) scheme closed to all new applications for accreditation at midnight on 31st March 2023. All applications submitted beyond this date will be rejected.

The RHI was a scheme available to businesses, the public sector and non-profit organisations designed to increase the uptake of renewable heat by providing financial incentives. It was open to eligible bodies where equipment was built on or following 15th July 2009 and met specific requirements. Successful applicants were granted a fixed tariff for renewable heat generated (p/kWh) over a 20-year period.

Since the scheme opened in 2011, the NDRHI scheme has supported 27,717 installations with a combined capacity of 5,980 MW. The scheme has paid out a total of £4.99 billion to participants for the 89 TWh of heat that has been generated. Over the scheme’s lifetime, a total of 2.1 billion cubic meters of green gas has been injected into the grid. As of December 2022, AD has provided 32% of heat under the RHI with ‘Biogas’ and ‘Biomethane’ generating 5,955 GWh of electricity and 21,491 GWh of heat respectively since the scheme opened.

Following its 11-year run, the NDRHI closed to new applicants on 31st March 2021. However, it was later extended on two separate occasions. DESNZ extended the NDRHI scheme for applicants who had suffered significant delays due to the COVID-19 pandemic, granting an additional year to the applicants who were successful in their application for an extension or a tariff guarantee. The department then extended the deadline for some applications by a further year to 31 March 2023.

As the scheme closed to new applications, the ongoing Green Gas Support Scheme (GGSS) is in place to provide financial incentives for new anaerobic digestion biomethane plants to increase the proportion of green gas in the gas grid. The GGSS launched its Mid-Scheme Review recently and ADBA is currently engaging with the members to help feed into the response to the Review.
