A small town with a demand of 800 kW of electric power at 220 V is situated 15 km away from an electric plant generating power at 440 V. The resistance of the two wire line carrying power is `0.5 Omega` per km. The town gets power from the line through a 4000-220 V step-down transformer at a sub-station in the town. Flow much power must the plant supply, assuming there is negligible power loss due to leakage?
