Texas electric grid seeks conservation amid spring weather

DALLAS (AP) — The electric grid manager for most of Texas issued an electricity conservation watch Tuesday, appealing to customers to conserve electricity despite weather conditions typical for spring.

The Electric Reliability Council of Texas, which previously came under fire after it was accused of mismanaging its resources in preparing for the historic freeze in February that killed more than 100 people, issued the watch Tuesday, one step below emergency action. It blames “a combination of high generation outages typical in April and higher-than-forecasted demand from a stalled cold front over Texas,” in a statement Tuesday by Woody Rickerson, vice president of grid planning and operations.

Most afternoon temperatures ahead of the front Tuesday were in the upper 70s and 80s and the 50s and 60s behind it — seasonable temperatures for the time of year, according to the National Weather Service in Fort Worth, Texas. Temperatures in a typical Texas summer often top 100 degrees, straining the state's power supply.

No power outages were expected, Rickerson said, but he wanted to alert customers as a precaution in the wake of the state’s deadly February cold wave.

Rickerson said ERCOT expected a cool front that stalled across Central Texas to have instead continued its progress across the state, lowering temperatures as it did. The fact that the front stalled resulted in higher demand than expected, he said, adding that demand eased as the afternoon sun faded but could repeat conservation appeals over the next three to four weeks.

However, 32,000 megawatts of generating capacity had been taken offline, accounting for about 25% of the systemwide capacity, Rickerson said. Whatever damage caused by the deadly February cold wave has been repaired, he said.

“Those outages are maintenance outages that plants have...
