The grants are being awarded by the National Lottery's New Opportunities Fund, which is supporting seven clusters of smaller bioenergy heating installations, and the Department of Trade and Industry, which is supporting four industrial heating installations with a heat capacity of over 0.5MW each.
Almost all of the projects will use wood and forestry residues as fuel.
The biggest grant of £0.88 million will go to Rural Energy to provide an integrated production and supply network for wood fuel and a cluster of some 800 small heating systems in the East Midlands. Boilers with an output ranging from 40 to 4,500kWh will be used.
One of the smallest grants of £0.19 million will go to Countryside Properties for a combined heat and power unit burning wood chip to supply a new development of 200 homes.
