A total of L4 million is available overall under Round 6 of the Bio-energy Capital Grants scheme, with grants up to L500,000 on offer to individual projects. These would pay for up to 40 per cent of the difference in cost between a biomass boiler and its fossil fuel alternative. Launching Round 6, Energy and Climate Change Minister Lord Hunt said: „As the world works towards a global deal on Copenhagen, back in Britain we are continuing to find greener ways to do business. We expect bio-energy to supply a third of our renewable energy by 2020 and these grants will help support that. „By March 2011 we plan to have 200 additional boilers installed, generating 87MW of biomass heat and over 72,000 tonnes of annual carbon savings.” The Bio-energy Capital Grants scheme will make up funding available to organisations who wish to install biomass boilers or Combined Heat and Power systems, including anaerobic digesters. These create energy from biomass such as wood chips and miscanthus, or from waste. The scheme has already assisted the installation of 458 biomass boilers in a wide range of buildings in both the private and public sectors. Nottinghamshire County Council have installed biomass boilers in over 50 schools in the county under the scheme. There was also a grant to support the 2MW biomass installation at Stansted Airport.
