HC Deb 25 April 1967 vol 745 c258W
112. Mr. Walters

asked the Minister of Power what is the estimated cost per kilowatt hour of meeting the unrestricted space-heating load at today's prices on accepted accounting principles, and on principles of long-range marginal costing, respectively.

Mr. Freeson

There is no single accepted accounting principle for expressing the cost of a part of the electricity load. The estimate of the long-range marginal cost of the unrestricted space-heating load made by a Working Party of the Electricity Council in 1964 was 1.65 pence a unit, subject to a number of qualifications. There are too many uncertainties for a meaningful recalculation to be made at the present time.
