asked the Secretary of State for Energy (1) what percentage of the heat wasted in generating plant is used in district heating systems;(2) what action has been taken since October 1973 to increase the use of waste heat from power generation; and by what percentage the heat waste has been reduced.
The supply industry is actively seeking opportunities for providing heat from power stations and both my Department and the CEGB are carrying out studies on combined heat and power. The proportion of heat from power stations used for district heating is at present very small. It is estimated that about 7 per cent. of total generation, public and private, is linked to some form of heat recovery. I have no information on the change that has occurred over the last year.
