Determine the load factor of the power station.

5.(a) Explain the different schemes for energy conservation in lighting.
"Minimizing idle and redundant running of a motor saves energy." Justify this statement.

6. Discuss in brief the roles and responsibilities of the Energy Auditor.
A power station is to supply for regions of load whose· peak loads are 10 MW, 5 MW, 8 MW and 7 MW. The diversity factor of the load at the station is 1.5 and the average annual load factor is 0·6. Calculate: Maximum demand on the station
Annual energy supplied from the station
