a) 0-10%

b) 10-20%

c) 20-30%

d) 40-50%

e) More than 50%

The graph below show the load for a local Colorado electrical power plant in March. Focus on the light blue curve (Month to Date Peak Curve). Perform a simple numerical integration (find the area under the curve) to see what load for the day would be. The ideas in the Friedman article would allow for that peak demand to be spread through the day via a smart grid, smart appliances, and variable costs for electricity based on demand. If that daily load was spread through the whole day (i.e. the area was the same but the line was completely flat), what percentage could be saved? (For example, if the current energy produced by operating to meet peak load is 12, 000 MWh and it was reduced to 9, 000 MWh, that would represent a 25% savings [(12, 000-9, 000/12, 000])

Explanation / Answer

Saving percentage= (350 MWh- 300 MWh)/(350 MWh)

= 0.14

= 14%

Option b is correct
