Cranbrook DH & CHP breakthroughs 2010
• £4.1m HCA low carbon infrastructure grant • Private sector ESCo proposition• Renewable Heat Incentive (RHI) • Skypark commercial development included in scheme
Cranbrook & Skypark Energy Solution
Energy Centre• 1.4 MWe natural gas CHP units and five 4 MWth Natural Gas boilers • Two advanced thermal gasification units linked to two 1.4 MWe CHP engines• Thermal stores• Output Capacity when fully operational 4.2 MW electricity and 25.4 MW heat• c 13,000 t /year CO2 savings per year
