Flattening The Curve

This chart shows a typical day of electricity demand in Ontario on July 5, 2010. It is provided by the IESO website at this link:  http://www.ieso.ca/default.asp

Notice that lowest actual demand for the day was at 5:00 a.m./~14,000 megawatts and the project high will be at 5:00 p.m / ~23,800 megawatts. The difference between the projected high and the low is 9,800 megawatts.

Here’s a graph showing the weekly demand from Aug. 23 – Aug. 29. Notice the weekly low on Aug. 28/~12,000 megawatts and the weekly high on Aug. 29/~20,000 megawatts. The average available demand capacity is ~ 27,000 megawatts. The above graphs are typical of electricity demand throughout most parts of North America. The actual numbers will be different but the shapes of the graphs are consistent.
