A proposed station has the following daily load cycle:
| Time in Hrs. | 6-8 | 8-12 | 12-16 | 16-20 | 20-24 | 24-06 |
|---|---|---|---|---|---|---|
| Load in MW | 20 | 40 | 60 | 20 | 50 | 20 |
Plot the load curve and load duration curve. Find the load factor of the plant and the energy supplied by the plant in 24 hours.
