ERCOT says a 400 megawatt CPS Energy plant may not be be fixed until mid-August. That could put state grid at risk.

An aging gas-fired generating unit in San Antonio, crucial for Texas grid stability, is facing significant delays in repairs, potentially remaining offline for up to 12 months. The Electric Reliability Council of Texas (ERCOT) had previously ordered CPS Energy to keep the unit operational past its planned retirement due to concerns over transmission line congestion. However, recent inspections have revealed unexpected issues, including the need to replace a critical component, which could push the unit's return to service to mid-August or later.

The escalating repair costs are also a concern, with estimates rising from $34 million to $46.5 million. ERCOT is working on deploying a fleet of portable generators to alleviate congestion in the San Antonio area, which may become increasingly necessary if the Braunig Unit 3 repairs are further delayed. Despite challenges, ERCOT is focused on ensuring these additional resources are available during peak summer demand to maintain grid reliability.
