Home » Power Systems » Power systems miscellaneous » Question

A consumer has a maximum demand of 60 kW at 0.50 load factor. If tariff is ₹ 750 per kW of maximum demand plus ₹ 1.20 per kWh, then overall cost per kWh, will be _________

1. 137
2. 1.37
3. 13.7
4. 0.137

Correct Option: A

Annual energy consumption
= 60 × 0.50 × 8760 = 262800 kWh.
Cost of annual energy consumption, C_E = (1.20) × 262800 = Rs. 315360
Fixed charge per year, C_F = Rs. 750 × 67 = Rs. 45000
Total annual charge = C_E + C_F = Rs. (315360 + 45000) = Rs. 360360

Overall cost per kWh =	360360	= 1.37
	262800
