Summary
Renewable Heat Incentive + Premium Payments
WHAT?
2 schemes providing financial support to domestic and non-domestic renewable heat generators
WHERE?
England, Scotland and Wales (RHI: off gas network)
WHEN?
RHI launched tomorrow; RHPP since 1 st August 2011
WHO?
Owners of eligible heaters recently/soon installed: ground & water source heat pumps, biomass, solar thermal, RHI: deep geothermal, biogas, municipal waste, biomethane injection
HOW?
955m € central Government funding, paid per unit of metered eligible heat for 20 years (RHI), plus capital grants (RHPP)
WHY?
UK RES target is 15% of energy - currently 1.5% (11% of heat - currently 1%). + Avoid carbon emissions up to 44 MtCO

Context - Existing incentives
Domestic
• Reduced VAT rate (5%) on small-scale RE
• Revenue from govt incentives exempt from tax
• New zero-carbon homes get relief on duty
Business
• Annual investment allowance
• Enhanced Capital Allowance for Energy Technology List products incl. GSHPs (plant only)
Industry
• £5m Deep Geothermal Challenge Fund 2009-11
= grants for major projects (>2 MWe or >5 MWth)

RHI & RHPP – Timeline
• Mar 2009 – UK RE Strategy & Targets
• Feb 2010 – Public consultation
• May 2010 – Change of govt
• Oct 2010 – Spending review confirmed RHI & set budget
• Mar 2011 – Details published
• Aug 2011 – RHPP launch
• Oct 2011 – RHI scheme launch
• Aug 2011 – RHPP ends
• Oct 2012 – RHI domestic launch
Intro 1 - Renewable Heat Premium Payments
• Government domestic renewable heat grant
• Selected EU RES (e.g. not stoves/cooling)
• Phase 1 , August 2011 – March 2012
Grants for eligible heat generators…
• Phase 2 , from October 2012
…+ RHI payments for metered heat
RHPP – How it works
The householder:
• Applies to EST * for grant ‘voucher’
• Installs biomass boiler/solar collector/heat pump
• Registers heater via the installer
• Redeems voucher & receives grant
• (probably) Joins RHI in Oct 2012
Owner must agree to heat metering & attitude surveys if randomly selected
* Energy Saving Trust = government’s consumer energy advisory agency
RHPP – Grant amounts
330 €
950 €
1,390 €
1,060 €
RHPP – Eligibility & standards
•
•
Domestic (social housing – special conditions)
Must be owner’s main home
• Off gas network
• Must be main heating
(except solar)
(except solar)
• Cavity wall insulation + 250mm loft insulation
• Product & installer registered with MCS
• Hence capacity below 45 kW th
• Installed by end Mar 2012 or voucher expiry date
“We will continue to monitor and review the performance of heat pumps in situ.”

Intro 2 - Renewable Heat Incentive
•
• Government payments for metered heat
• Non-domestic until Oct 2012
EU RES but not ASHP, stoves, cooling
• Paid over 20 years
• Rate of return vs fossil fuel 12% (6%)
• World first?
Starts October 2011
Renewable Heat Incentive – How it works
RHI – How it works
Tariff rates calculated to:
• compensate for cost of RE plant over fossil
• cover both installation & running costs
• provide return on additional capital invested
• be incentive to overcome non-financial barriers
After the start of the scheme, tariff levels will be adjusted automatically each year in line with the Retail Price Index (RPI). This adjustment will be applied both for new and existing projects.

RHI – Standards
All heat pumps
• Required: CoP 2.9 or above ( heat pump only )
• May change when EC issues guidance
Heat pumps ≤ 45 kW th
• Must conform to UK Microgeneration Certification Scheme
• MCS covers installer, product, design & installation standards
Heat pumps > 45 kW th
• Ofgem will verify eligibility
• No standards other than CoP (above)
“We will continue to monitor and review the performance of heat pumps in situ.”
RHI – High temperature geothermal
• Same tariff as ground source heat pumps
“We intend to consider whether specific tariffs for deep geothermal heat can be introduced from 2012 ”
“There are no MCS or equivalent standards so, for the RHI, Ofgem will verify eligibility based on the documentation required”
• … i.e. no technical standards for deep geothermal
NB Cogeneration under the RHI
• Heat element only is eligible for payments
• No additional support for CHP - RHI deemed sufficient
RHI & RHPP – Impact predictions
• 110,000 public/commercial installations
• 13,000 industrial installations
• ?? domestic installations
contribute to 100,000 new RES jobs
• directly stimulate 5.0 billion € capital investment
• generate 57 TWh th by 2020
RHI & RHPP – Criticisms & issues
• Lack of installer/product/design standards >45kW
• July 2009 cut-off – unfair, or practical?
• Exclusion of log/pellet stoves & bio-liquid fuels
• Exclusion of cooling and ‘waste heat’
• No additional support for extra costs of district heat
• Air source heat pumps – always sustainable?
• Biomass fuels/emissions – always sustainable?
• Some wanted payments assignable to 3 rd parties
• Some wanted fossil fuel suppliers to pay RHI
RHI – Opportunity for ground energy
