As Dallas-Fort Worth prepares for triple-digit temperatures this week, the Electric Reliability Council of Texas registered its peak usage of the year so far.
Only four days into summer and Texans have already racked up a yearly peak for electricity usage, according to the Electric Reliability Council of Texas.
ERCOT reported Monday that electricity demand topped 60,000 megawatts for the first time in 2013. The grid has a maximum output of more than 64,000 megawatts, according to ERCOT.
Temperatures reached the mid to high-90s in North Texas, and they're expected to hit triple digits by the end of the week.
The sweltering summer of 2011 set the standard for electricity demand - with a record-breaking 70 days of 100 degrees or higher in Dallas, according to the National Weather Service.
ERCOT manages electricity for 23 million Texas customers, which represents 85 percent of the state's electric load.
