Hot Weather Puts Pressure on California's Energy Grid

The non-profit that manages the state's energy grid said Sunday that conservation was needed to avoid straining the system.



    Valley Bakes Under Late-Summer Scorcher

    Southern California continued to bake under triple-digit temperatures as a late-summer heat wave gripped the region. Ted Chen and Fritz Coleman report for the NBC4 News at 6:30 p.m. on Aug. 12, 2012. (Published Sunday, Aug. 12, 2012)

    Despite hopes that the region’s high heat would abate by the weekend, temperatures Sunday started climbing early.

    The hot day followed a night that never really cooled down – just the kind of situation that can cause problems for the state’s power grid and put strains on the aging infrastructure that delivers electricity to millions of California homes.

    Examples of the hot temperatures include the cities of  Livermore, Pleasanton and Fairfield hitting 105 degrees on Saturday.

    Sunday is shaping up to be similar, according to NBC Bay Area meteorologist Rob Mayeda.

    Another Hot Day on Tap

    [BAY] Another Hot Day on Tap
    Our uniquely Bay Area summer microclimates are in full swing this weekend, though our inland valley temps are running hot by our standards. Examples included Livermore, Pleasanton and Fairfield near 105 on Saturday! Sunday is shaping up to be very similar, expept we will have a slightly earlier onset of the afternoon sea breeze coupled with a deepening marine layer late in the day. This should mean a little bit of cooling for the inner bay and bayside valleys, yet valleys further inland especially near the Tri-Valley and areas south of San Jose will see temps rise well into the 90s to near 100 again. Slow, but steady cooling will drop inland temps a few degrees each day through midweek which will bring some heat relief inland and better air quality as well for the entire Bay Area.

    Mayeda says there will be some relief in the afternoon  when a sea breeze coupled with a deepening marine layer moves in. 

    The beaches up and down the state were expected to be a good 20 degrees cooler than the hottest parts of the valleys.

    The continued heat will lead to high demand for energy as people try to keep homes and businesses cool, the non-profit company that manages the state’s energy supply said Sunday.

    The California Independent System Operator (Cal ISO) predicted that Californians would use 41,309 megawatts of power during the day. There’s enough energy in the system to meet that demand, the company said, as long as residents conserve.

    Conservation on Sunday, while not mandatory, is needed to keep electricity flowing in the state, the system operator said on its website.
