Regional Overview Renewable ElectricitY • The survey identified 215 grid connected renewable electricity projects in the South West. An additional 64 projects have been identified since the last survey was undertaken in March 2006, 47 of which have been installed in the last year. The others are existing schemes which have been identified due to better reporting, and include two sewage gas schemes, one at Netheridge in Gloucestershire and one in Swindon, Wiltshire. • The installed capacity for renewable electricity now stands at 137 MW, up 14.4 MW since the last survey. The vast majority of this increase is due to changes in generator capacity at the region’s landfill gas sites, and the identification of two sewage gas sites in Wiltshire and Gloucestershire. Only approximately 300 kW of this increase is due to new installed electricity capacity – other than landfill gas. • Renewable electricity schemes in the region are now producing enough electricity to supply the equivalent of 119,828 homes, avoiding the production of 423,031 tonnes of carbon dioxide a year. • There are 31 landfill gas schemes making up 51.8% of total installed capacity, 16 sewage gas schemes making up 7.9%, 32 onshore

wind projects, 31.3%; 47 small hydro schemes making up 6.2 %; 87 solar PV schemes making up 0.6% and 2 schemes dealing with advanced treatment of waste making up 2.1%. • Planning remains a large barrier to the development of renewable energy in the South West. The region has a very long way to go to achieving its 2010 renewable electricity target of securing 11-15% of generating capacity from renewable sources (approximately 597 MW). • In the last 12 months only two large schemes have been approved at committee, a 2 MW biomass plant in Wiltshire and a 7 MW pyrolosis plant in Somerset. Two further schemes totalling 20 MW have been approved planning permission on appeal. In the last 12 months 3 schemes equating to 9.1 MW have been refused planning permission at appeal. There are 3 further schemes in the region awaiting appeal totalling 58 MW and a 66 MW Section 36 application currently with the DTI. • The region has approximately 40 MW of projects that have been approved in the last couple of years, waiting to be built. This includes a 6 MW wind farm at Avonmouth where construction has begun, and an 18 MW wind farm at Den Brook, Devon, where construction is due to start next year.

1 a. Energy generated has been estimated using typical factors for different renewable energy technologies:

LFG 80%, wind 30%; sewage gas 60%; small hydro 25%; advanced technology 80% and PV 30%. b. The number of equivalent homes powered is based on the assumption that an average house consumes 5,000 units of electricity (kWh) a year. c. Carbon savings are based on a DTI figure that the average carbon dioxide emission per kWh of electricity generated in the UK is 0.598 kg.

Regional Overview Renewable Heat • The survey identified 419 renewable heat projects in the South West. The installed capacity of these projects is 27.85 MW. This is an increase of 7.42 MW since the last survey in March 2006. • The largest renewable heat scheme installed in the last year was a 3 MW biomass thermal boiler in Cornwall, at a plant nursery in Kernock. • Heat pumps make up 4.38 MW or 15.7% of total renewable heat capacity, solar thermal 1.24 MW or 4.5% of capacity, biomass thermal 10.07 MW or 36.2% of capacity, and Sewage Gas CHP makes up 12.15 MW or 43.6% of installed capacity. • Although the installed capacity of renewable heat projects is still small in the South West, the carbon reduction benefit is likely to be significant because many projects are installed off the main gas network, and displace heating oil which has a high carbon content.

Former Avon • The four unitary authorities which make up the former Avon area have increased their installed renewable electricity capacity to 11.47 MW, making up 8.4% of the region’s installed capacity. Avon’s renewable electricity schemes now generate the equivalent electricity needs of 10,048 homes. Avon’s largest scheme is a sewage gas scheme at Avonmouth sewage treatment works which produces heat and electricity, with 5.75 MW installed electricity capacity. • Avon should increase its capacity in the next year as construction on a 3 turbine, 6 MW wind farm at Avonmouth is currently underway. • Bristol City is the top-ranking local authority area in Avon, in terms of installed capacity with over 6 MW installed, and six projects installed. This capacity is largely due to its sewage gas scheme at Avonmouth.

• The former Avon area has the largest renewable heat capacity in the region at 8.01 MW. Some 7 MW of this heat capacity is from the Avonmouth sewage gas combined heat and power site. • Bristol City Council has the highest renewable heat capacity of any local authority area in the region, due largely to the heat capacity from its sewage gas site. • Bristol City Council won a South West Green Energy Award in 2006 for a 400 kW biomass boiler which provides heat to a series of nurseries at the Blaise Nursery site. The boiler is the first of its kind in Bristol. The council has also built a wood fuel depot next to the boiler where aboricultural arisings can be stored for the nursery boiler and other future wood heating boilers around the city.

Cornwall & the Isles of Scilly • Cornwall remains the leading county in South West England for installed renewable electricity capacity with 52.79 MW, making up 38.6% of the total installed capacity for the region. Cornwall’s capacity generates power for the equivalent of 46,244 homes. • Cornwall is awaiting the construction of a 1.8 MW wind cluster at Roscrow Barton, which was approved in 2004. • North Cornwall is the leading local authority both in the county and in the whole region. This is due to the district having four wind farms, making up 23 MW of installed capacity. Kerrier District Council and Carrick District Council take second and third place in the region for installed renewable electricity capacity.

• Cornwall has the second highest installed renewable heat capacity in the region at 7.5 MW, and the highest number of renewable heat schemes in the region with 158 schemes. • In 2006 a 3 MW biomass boiler at Kernock Nurseries was installed. This is the largest biomass project installed to date in the region. • In 2006, Carrick Housing Association won the South West Green Energy Award for Best Housing Scheme. The Housing Association has installed some 200 GSHP’s in social housing in the last year.

DEvon • Devon has the largest number of renewable electricity projects in the region with 68 installed projects and the second highest installed capacity at 28.93 MW, or 21.1% of the regional capacity. Devon’s installed renewable electricity capacity generates the equivalent electricity needs of 25,343 homes • Devon has the potential to significantly increase its renewable electricity capacity in the next few years, and become the leading county in the region in terms of installed capacity. An 18 MW wind scheme at Den Brook, West Devon has

recently been given planning permission on appeal, and there are two large wind schemes currently in the planning system in North Devon, totalling some 84 MW. If approved, Devon would be close to meeting its 2010 target of 151 MW, and North Devon would be at the top of the district rankings across the region. • Torridge District has the highest installed renewable electricity capacity in Devon, due to a 3 MW wind farm at Bradworthy, the 2.7 MW Holsworthy Bio-Gas plant and a landfill gas site.

Somerset •

Somerset has 9.34 MW of installed renewable electricity capacity, making up 6.8% of the region’s total capacity. Somerset’s renewable electricity schemes generate enough power for the equivalent electricity needs of 8,181 homes.



Somerset’s first wind turbine was approved on appeal in 2006. This is a 2 MW turbine at Shooters Bottom. Somerset has the potential to significantly increase its installed renewable electricity capacity, due to an initiative by the County Council which is looking into installing up to 12 MW of wind turbines on Council owned land.



South Somerset District has the highest installed capacity of the local authority areas in the county at 5.19 MW. This is due largely to two landfill gas schemes in the area (Dimmer and Odcombe).
