A generating station has a maximum demand of 75MW and a yearly load factor of 45%. Annual Generating costs inclusive of station capital costs are 1200 Dinars/kW demand plus 80 Dinars/kWh transmitted. The annual capital charges for transmission system are 40 million Dinars and for distribution system 30 million Dinars ; the respective diversity factors being 1:3 and 1:4. The efficiency of transmission system is 90% and that of the distribution system inclusive of substation losses is 85%. Find the yearly cost per kW demand and cost per kWh supplied : (1) at the substation (2) at the consumers premises.
