ISO Issues Statewide Flex Alert

Electricity conservation needed due to natural gas shortage curtailing fuel supplies to power plants

FOLSOM, Calif.--()--A shortage of natural gas triggered by extreme cold weather in much of the United States and Canada is impacting fuel supplies to Southern CA power plants and reducing electricity generation. The California Independent System Operator Corporation (ISO) is issuing a statewide Flex Alert for today, February 6, 2014.

While the natural gas shortage is only impacting Southern California power plants, statewide electricity and gas conservation will help free up both electricity and gas supplies for Southern Californians. Customers in both Southern and Northern California are asked to reduce their energy use between 1:00 p.m. until 10:00 p.m.

Today Thursday, February 6, is a Flex Alert Day!
