For the capacity charges for directlyconnected supply points and Cseps these costs are the total costs detailed in 3.2.7b above.Functions are fitted to the data points such that the error term is minimised. The functions found tobest fit the underlying average cost data are in the form of a power of the peak daily load (SOQ) withstraight-line elements for the domestic (
