"Electricity, like water, is something we need to preserve and need to use wisely," Steve Mild, San Angelo's Emergency Management Coordinator, said.
With cold temperatures and high electric use, most likely from heat in homes and businesses, an energy emergency alert was sent out warning emergency managers that if electricity use got much higher, brownouts might occur.
"That is done so that the generating equipment doesn't get overloaded and break down and then you have no electricity going anywhere," Mild said.
In just under 10 minutes, the warning was lowered to a watch, but electricity use is still high. ERCOT says you can reduce the energy usage during this time by unplugging non-essential lights and appliances and avoiding washing your clothes and using ovens during peak hours: 6 a.m. to 9 a.m. and 4 p.m. to 8 p.m.
"Also adjust your heat, preferably no higher than 69 degrees, and that way you are reducing the amount of electricity that is being used however you're still keeping a liveable temperature in the house," Mild said.
While a brownout is not expected during this cold-front, if one were to occur, Mild says it would not last more than 10 to 45 minutes.
