There is acertain critical point, however, to which the firm purchasedpower line may be raised before the total cost (which is ofprime importance) of combined purchased power and steampower will commence to increase. In raising the firm line ofpurchased power to this point the total cost will be decreas-ing. It is hardly possible to evolve an ex
