Beto O'Rourke knocked Gov. Greg Abbott on Sunday night after the state's grid operator appealed to Texans to "voluntarily conserve electricity" during a statewide heat wave.

The governor of the world's ninth largest economy can't guarantee the power will stay on tomorrow. Change is needed.

The Electric Reliability Council of Texas (ERCOT) issued a "conservation appeal" on Monday asking people to cut back on electricity use during the evening hours. The need for this important action by customers was driven by the record high electric demand during the heat wave.

Texans were urged to turn down their thermostat and not use pool pumps during the six hour period.

In May, the grid operator made a similar request after six power plants shut down during a heat wave.

When it's hot, we can't rely on the grid. The grid can't be relied on when it's cold. Greg Abbott can't be relied on. It's time to vote him out and fix the grid according to O'Rourke.

O'Rourke will face Abbott in the general election in November. According to the Texas Politics Project at the University of Texas at Austin, Abbott leads O'Rourke by 6 points.

The former congressman has used the Lone Star State's energy grid as a talking point on the campaign trail.

He was a fierce critic of Abbott and other lawmakers for a major grid outage that left thousands of Texans without power for days.

"We now know that the Texas government's repeated failure to modernize our energy systems killed over 700 Texans in February's winter storm."

In light of the ERCOT appeal, a Dallas Morning News headline was posted by Texas Democrat Julin Castro, who was in the ring with O'Rourke.

Life in Texas these days. He said thanks to Greg Abbott.

The Hill reached out to Abbott's office and ERCOT for comments on O'Rourke.
