A Stage One Electrical Emergency is expected to be issued today, August 30, 2007, in California. A Stage Two Emergency could follow this afternoon. This is the second day in a row that the California ISO issued a "Flex Alert" requesting that customers conserve energy.
The California Independent System Operator Corporation (California ISO) is expected to access its seven percent reserve margin. In the event they must access the reserve, a Stage One Emergency will be declared. Experts are forecasting the peak demand power for today to be at 49,500 megawatts. The record peak demand ins 50.270 megawatts.
A Stage Two Emergency is declared when the energy reserves fall below five percent. Large commercial customers that have previously signed up to voluntarily restrict their power usage will be asked to do so at this level. In the event that the operating reserve is expected to drop below and and a half percent, Stage 3 is initiated. Stage 3 is what is commonly referred to during "rolling blackouts" that involve involuntary curtailments of power to customers.
There are two factors that are contributing to the concerns of energy reserves. The first being a regional heat wave, and the second is a low hydroelectricity level throughout the state, due to the dry winter.
Conservation Tips!
- Set your thermostat to 78-80 degrees when possible, and turn it off when the home is unoccupied.
- Turn off all unnecessary lighting, and avoid using major appliances during peak usage hours 4 to 6 pm.
- Shut off your sprinklers and pool pump during peak hours.
