Though the overall summer outlook calls for adequate electricity supplies, the transmission system could get congested on hotter than normal days when air conditioning use goes up significantly. In response, calls for energy conservation may go out. There are several types of energy conservation alerts. These include;
- Demand Response events like Reduce Your Use days and Critical Peak Pricing call for reducing or shifting electricity use during peak periods. Notification for these events happens through My Account and is also posted on SDG&E’s website. If you aren’t signed up to receive event notifications, log on to sdge.com/MyAccount and click on alerts and subscriptions to follow the prompts for enrolling.
- Flex Alerts are issued by the California Independent System Operator (ISO). The ISO manages the flow of electricity across the high-voltage, long distance power lines that make up 80 percent of California’s and a small part of Nevada’s power grid. Flex Alerts can be triggered by heat waves, when electricity demand exceeds supply. Flex Alerts are posted on the ISO website, sent by emails and texts to people who sign up for notifications, and are posted to Twitter and other social media outlets. The ISO notifies the media when a Flex Alert is issued.
