To ask the Secretary of State for Energy what are the latest estimates from the Energy Technology Support Unit of the potential kilowatts that could be contributed from combined heat and power; by how much such potential would raise the overall thermal efficiency of electricity generation; and what percentage contributions this could make to a reduction in greenhouse gas emissions.

The latest estimate is that a potential of 25 billion kilowatt-hours annual generation from small scale CHP, operating at an efficiency of around 80 per cent. could reduce United Kingdom carbon dioxide emissions by 4 per cent.This level of output equates to about 10 per cent. of present United Kingdom electricity demand or the output of about four large power stations.


To ask the Secretary of State for Energy if he will make a further statement on combined heat and power schemes.

I refer the hon. Member to the replies I gave to him on 18 December 1989, Official Report, column 8, and 29 January 1990, column 83.
