Abstract
THE Central Electricity Board in conjunction with the National Consultative Technical Committee has prepared a form of tariff laying down the principles under which electricity will be supplied directly to authorised undertakings. This form of tariff applies to the whole of the supply given to undertakings which do not own ‘selected’ stations. It applies also to that part of the supply to selected stations which they do not generate for themselves. The new tariff consists of three parts. The first is a service charge in respect of each point of connexion to the grid, the second a fixed annual power charge based on the maximum demand for power during the year at each point of connexion, and lastly, a running charge for each kilowatt hour supplied. No service charge is made for the first point of supply. The kilowatt charge is based on the maximum demand for the year. This maximum demand is taken to be twice the largest number of kilowatt hours supplied during any half-hour in the months of January, February, November and December. This tariff has been agreed with the District Committee for mid-east England and the central Scotland tariff will be decided shortly. The tariff system, although at first sight complicated, is based on sound principles and should prove practical. Various modifications have to be applied when the energy supplied is less than the product of the volts and amperes, that is, when the power factor of the load is low. The application of the Act has necessitated the evolution of instruments which will measure both kilowatts and kilovolt amperes respectively. Accurate instruments of this type are now available. It will be interesting to see the magnitude of the reductions in price to the consumer in mid-east England.
