A load having a peak value of 50 MW and 45% load factor is to be supplied by a steam power station in conjunction with a hydro-power station, the latter supplying 60 million units of energy per annum with a maximum output of 20 MW. (i) Capital cost Steam: Rs 2000 per kW installed Hydro: Rs 3000 per kW installed (ii) Cost of fuel Coal Rs 150 per metric ton; consumption being 0-5 kg per unit generated (iii) Maintenance charges Steam: 0-7 paise per unit Hydro: 0-5 paise per unit (iv) Interest and depreciation Steam: 10% per annum Hydro: 9% per annum Calculate the average cost of energy
