per kWh.

Capital cost = Rs. 70,000

Interest and depreciation = 10%
ii) Private oil engine generating station.

Capital cost = Rs. 2,50,000

Fuel consumption = 0.3 kg per kWh

Cost of fuel = Rs. 70 per tonne

Wages = 0.4 paise per kWh

Maintenance cost = 0.3 paise per kWh

Interest and depreciation = 15%.
