Abstract :
A proposal is put forward to divide consumers into two classes, viz. those requiring a supply for 7 days a week and those requiring a supply for 6 days a week; and a method is shown for obtaining a separate fixed charge, on the Hopkinson principle, for each group. The advantages of dividing consumers as suggested are then considered, and an improved method of ascertaining the value of a coal clause is given. Proposals are put forward to add a fixed-charges clause, varying automatically with the price of coal, and to record the percentage of output to plant kilowatt-hours run, for statistical purposes.
