Strain on the counties power grids are expected as the week's hot temperatures are to drive up people's use of air conditioners.

The California Independent System Operation Corporation (ISO) issued a statewide Flex Alert on Monday, asking California residents to voluntarily conserve electricity through Wednesday evening as a heat wave sweeps through the state.

Cal ISO, the state's power grid operator, is asking residents to voluntarily conserve electricity between 2:00 p.m. to 9:00 p.m. on Tuesday and Wednesday.

With temperatures reaching triple digits through Borrego Springs and surrounding towns, San Diego Gas and Electric (SDG&E) are encouraging customers to conserve energy despite stating that they do not anticipate having issues meeting the energy demand over the course of the week.

SDG&E is also offering the following tips to help conserve energy...

Set thermostat at 78 degrees when home

Use fans instead of A/C

Unplug TV, cable, DVD, or gaming devices when idle or use smart power strip

Turn off unnecessary lights

Hold off on doing laundry and using dishwater until after 9 p.m.

Use compact fluorescent lamps or LEDs

Close blinds, shades, or drapes during hottest part of the day

Check weather-stripping around doors and caulking around windows

If you have a pool, check pool pump
