California power grid declares emergency amid record-breaking heat wave
Driving the news: "We need 2 to 3 times as much conservation as we've been experiencing to keep the power on with these historic high temperatures and demand," the grid's chief executive, Elliot Mainzer, said Monday.
- "We're looking at energy deficits at 2-4,000 megawatts, which is as much as 10% of normal electricity demand," he said.
- "The potential for rotating outages has increased significantly," he added, noting that the forecasted demand for Monday and Tuesday is at "all-time record levels."
The big picture: The sustained heat wave in California is likely to intensify throughout the week, threatening monthly and all-time temperature records beginning today and lasting until next weekend.
- The operator of the electrical grid has already called on residents to conserve energy, particularly from 4pm and 10pm local time.
Our thought bubble, via Axios' Andrew Freedman: The California grid is under stress in part due to a long-lasting, extreme drought that has reduced hydroelectric power output, and the ongoing heat wave that is itself record-breaking.
- Officials are warning that rolling outages are likely to be necessary as demand exceeds supply, particularly during peak times of the day.
- Given the persistence of the heat, and the fact that it is hitting nearby states that could otherwise export power to California, continued challenges await throughout the week.
