Renewable Heat Incentive

The Renewable Heat Incentive (the RHI) is a payment system for the generation of heat from renewable energy sources introduced in the United Kingdom on 28 November 2011. The RHI replaces the Low Carbon Building Programme, which closed in 2010.

The RHI operates in a similar manner to the Feed-in Tariff system, and was introduced through the same legislation - the Energy Act 2008.[1] In the first phase of the RHI cash payments are paid to owners who install renewable heat generation equipment in non-domestic buildings: Commercial RHI.

The RHI went live on 28 November 2011 for non domestic buildings. The Coalition Government confirmed its support for the RHI in the October 2010 Spending Review and published details on 10 March 2011.[2] The RHI was extended to domestic buildings on 9 April 2014 after a further series of delays. Three consultations were launched which included proposed domestic tariffs and a long discussion on eligible technologies along with changes to the Commercial RHI which included proposals to triple the tariffs for ground source heat pumps and the proposed addition of a tariff for Air to Water Heat Pumps.

Commercial RHI

Through the Commercial RHI, generators of renewable heat for non-domestic buildings can be paid up to 10p/kWhr for hot water and up to 8.7p/kWhr for heat which they generate and use themselves. The RHI tariff depends on which renewable heat systems are used and the scale of generation. The annual subsidy lasts for 20 years for non-domestic buildings, and seven years for domestic buildings. As such, users may earn enough money from the tariffs to pay off their installation costs in five to eight years. According to the Government, which has set the tariff levels, users will earn a return of 12% per annum. This will be tax free for individuals. The equivalent for Feed-In Tariffs is 5%-8%.

The RHI provides support for community and district heating schemes where a single renewable heat system provides heat or hot water to more than one property.

Eligibility for Commercial RHI

The renewable heat technologies which are eligible under the Commercial RHI are solar thermal (hot water) panels, ground source heat pumps, water-source heat pumps, biomass boilers, and biomethane. The list was extended in April 2014 to include air to water heat pumps and deep geothermal. See table of tariffs[3] for the Commercial RHI.

Criticism of the Commercial RHI

Although based on the Energy Act 2008, the Commercial RHI was not introduced until November 2011. Although intended to support a range of renewable heat technologies, nearly all the initial incentives were paid for biomass boilers. The larger initial tariffs for biomass boilers decreased the demand for other renewable technologies including heat pumps and solar thermal. From May 2014 the Commercial RHI tariffs have been realigned with increased tariffs for ground source heat pumps and the introduction of RHI tariffs for air to water heat pumps. The effect of prescriptive legislation has been to inhibit innovation in renewable technologies - although one of the stated aims of the RHI has been to encourage innovation.

Domestic RHI

The introduction of Domestic RHI has been delayed many times following a series of tardy consultation processes. The latest delay is from summer 2013 to April 2014. It is now available for eligible installations commissioned from 15 July 2009 onwards. Any installation taking place between September 2011 and 31 March 2014 was eligible for the Renewable Heat Premium Payments which consisted of a small upfront payment prior to the RHI being introduced.

Eligibility for Domestic RHI

Through the Domestic RHI, generators of renewable heat for single domestic buildings can be paid up to 19.2p/kWhr for hot water and up to 18.8p/kWhr for heat which they generate and use themselves. The RHI tariff depends on which renewable heat systems are used and the scale of generation. The tariffs are larger than for the Commercial RHI, but are paid over seven years, rather than for 20 years for non-domestic buildings. See table of tariffs[4] for the Domestic RHI.

Criticism of the Domestic RHI

Although based on the Energy Act 2008, DECC has taken six years before introducing the Domestic RHI. Delays have been very damaging to the renewable energy industries – which DECC claims to be supporting.

The RHI has suppressed innovations in renewable energy sectors by excluding from incentives any technologies which are not already well established.

The effect of DECC’s policies has been to encourage inefficient technologies and to suppress efficient technologies because the subsidies are based on complex and ill understood calculations of the cost of each technology in order to provide more subsidy to the more expensive technologies and lower subsidies for the less complex technologies.

All Renewable Heat Incentive applications for domestic RHI must be accompanied by a Green Deal Advice report. The uptake of Green Deals has been very low and the requirement to pay for a Green Deal Assessment may be inhibiting the uptake of the domestic RHI.
