Texas Public Utility Commissioner Shelly Botkin resigned Monday, leaving the three-person body with just one member, Chair Arthur D’Andrea.

The Texas PUC declined to reprice $16 billion in market transactions that may have been incorrectly priced during the February winter storm.

The names of potential successors to ERCOT CEO Bill Magness have already begun to circulate after the grid operator’s Board of Directors fired him.

Under heavy fire from state politicians over her response to the massive Texas blackouts, DeAnn Walker resigned as the chair of Texas’ PUC.

Texas lawmakers took their shots at ERCOT as they tried to grasp the complexities of a system that failed during an “unprecedented weather event.”

ERCOT CEO Bill Magness detailed for the Board of Directors the events that led up to last week’s near collapse of the grid during a severe winter storm.

Five out-of-state members of ERCOT’s Board of Directors, including new Chair Sally Talberg, told the Texas PUC they will resign Feb. 24.

With the ERCOT system back to normal operations, Texas politicians and regulators are taking initial steps to ensure a similar crisis doesn’t happen again.

ERCOT said that enough generation had returned to service to stop the rotating outages that began Feb. 15.

ERCOT leadership made it clear that it is fully committed to restoring power to the millions of Texans spending their fourth night shivering in the dark.
