Flex Alerts? What Are They and How Can I Help?


Summer heat waves combined with natural gas curtailments may cause rolling blackouts in Pasadena and the surrounding areas. Caltech and Pasadena Water and Power are working together to help minimize the impact to the Caltech community this summer.

Over the summer Flex Alerts may be declared as a call to conserve. If a Flex Alert is declared, please do your part to help by turning off unnecessary lights, appliances and other devices that consume electricity. Voluntary reductions during a Flex Alert can help us avoid blackouts.
