Rolling blackouts can be caused by a variety of circumstances such as extreme high heat or interruption from one of the state's major power supplies. This summer, the primary concern for rolling blackouts may be due to natural gas curtailments from SoCalGas related to the Aliso Canyon Facility gas leak. Aliso Canyon provides the natural gas needed to operate the electric generators for much of the utilities in the Los Angeles Basin region, including Pasadena. As a result of the subsequent reduction of natural gas supplies, SoCalGas has worked with local utilities to conserve natural gas, especially during peak hours of high heat where customers rely on electricity to cool down their homes.
As this year's high heat season draws to a close, it is important to remember that rolling blackouts may still be a cause for concern next year. Aliso Canyon may resume normal operations in the future, but it is still imperative that PWP customers continue to conserve energy whenever possible, as rolling blackouts can occur from many other circumstances.
Remember: PWP will do everything possible to avoid interruption to your electrical service. In fact, Pasadena has made great strides to ensure our energy portfolio is diverse with renewable and traditional sources.
This winter, you may receive language encouraging you to reduce your usage of household items like water heaters and furnaces that rely on natural gas, which is provided to you by SoCalGas. Click here for tips on how to reduce your natural gas usage during the colder months.
It is imperative that everyone does what they can to reduce consumption, particularly during extreme heat. Follow these tips to help do your part:

A Flex Alert is a call for consumers to conserve electricity during heat waves when power use outstrips electricity supply. It also calls for conservation during other challenging grid conditions, such as when power plants or power lines are unexpectedly unavailable, making electricity deliveries difficult.

Pasadena, along with a number of other utilities in the Los Angeles, relies on natural gas to help generate local power supply. Pasadena is aggressively exploring alternative power sources to address the potential shortage of natural gas.
Providing you with safe and reliable power remains one of our top priorities. However, it is important to recognize that depending on weather conditions and the community's ability to conserve energy, anticipated cutbacks on natural gas supplies from the Aliso Canyon Natural Gas Storage Facility could lead to rotating outages (AKA "rolling blackouts") this summer.
PWP could also be required to participate in rolling blackouts when necessary to maintain reliability of the regional grid, even if all our generation resources are available and operating.
While PWP strives to keep customers informed about the possibility of rolling blackouts, system conditions can change quickly and unpredictably. Furthermore, we not publicly announce the specific location or boundaries of current or expected outages for your safety and security. To learn more, visit http://conserveenergysocal.com/
