Resource Availability
Food Waste ≈ 16 Mt/y ! Purpose Grown Crops…
≈ 8.3 Mt/y household
≈ 6.3 Mt/y commercial & industrial “…Government policy is to deliver an
increase in energy from waste through AD.”
≈ 1.3 Mt/y food service & retail
“We recognise that at farm-scale, some
Agricultural Waste ≈ 90 Mt/y energy crops may be required…and that
such crops can be grown as part of the
≈ 13 million cattle
normal agricultural rotation. Furthermore,
≈ 33 million sheep there is land available which is not suitable
≈ 4 million pigs for the production of food crops but which
≈ 166 million chickens may, therefore, be used to supply energy-
crop only AD plants.”
Sewage Sludge ≈ 1.73 Mt/yr “It is not our policy…to encourage energy
crops-based AD, particularly where these are
grown to the exclusion of food producing
crops.”

Renewables Obligation
The Renewables Obligation (RO) for large-scale (generally >5MW) renewable electricity
projects.
ROCs issued to accredited generators for renewable electricity.
Introduced in April 2002
Banded from April 2009
Double ROCs for Anaerobic Digestion
• ROC value c. £44 – 50 per MWh
Banding Review due 2013, consultation open now.
– Proposing 2 ROCs in 2013 – 14
– Degression of 0.1 ROC per year thereafter
EMR post-2017, details yet to be published

Feed-In-Tariff
Feed-in Tariffs (FITs) provide a guaranteed price for a fixed period to small-scale (< 5MW)
electricity producers;
– Generation Tariff – the generator is paid for every kWh of electricity generated.
– Export tariff – for electricity exported onto the National Electricity Grid.
[Generators can opt in or on an annual basis, deciding whether to claim this or
the market value for the electricity.]

Renewable Heat Incentive
• The Renewable Heat Incentive is intended to provide financial support to encourage
a switch from fossil fuel heating to renewable sources.
• England, Wales and Scotland
• Two-phase approach:
2011: non-domestic sector e.g. from large-scale industrial heating to SMEs and
community heating projects.
2012: domestic sector and perhaps additional technologies (bioliquids, air-source
heat pumps, etc)

RHI Structure
• Tariff levels are intended to provide a rate of return of 12% on the additional capital
cost of renewables over conventional heat systems.
• Opened for applications Monday 28th November 2011 (delayed since 30th September)
• Payment period is guaranteed for 20 years from installation.
• Payments will be made quarterly.
• A review of tariffs is scheduled every four years, from 2014;
– Interim adjustments will take into account inflation –RPI linked annually
– Degression will apply

Conclusion
• The UK has come a long way in just a few years,
• But, barriers to development remain in place.
• To see a “huge increase” in AD we need;
Long-term security
- Policy
- Incentives
- Feedstock supply
Confidence
Investment
Strategy & planning
Regulatory framework
