§ Mr. Gordon Wilsonasked the Secretary of State for Energy how many studies into utilisation of waste heat from power stations were conducted by the Combined Heat and Power Group; what current research is proceeding; what applications for use of waste heat have been approved; and what has been the cost of the exercise.
§ Dr. John CunninghamMembers of the Combined Heat and Power Group have carried out a range of generalised strategic studies on the use of waste heat from power stations and these have been published in Energy Paper No. 20. The group has also commissioned several studies on various aspects of the subject and the results will be made known when the group's report is published. Specific studies which have been made by the electricity supply industries and their consultants on the use of waste heat from power stations in Glasgow, Peterborough and Central London have been examined by the group. Research is at present proceeding on determining the heat load densities in various cities of the country in order to establish the maximum potential application for the technique in the United Kingdom. In February, the Secretary of State approved a new power528W station to be built for the Midlands Electricity Board in Hereford to supply electricity to the grid and also steam and hot water to neighbouring fims. The total cost of the group's work is not known, since many individuals and organisations have made major contributions without payment.
