AI generated summary
ERCOT's request for must-run alternatives (MRAs) in San Antonio to address congestion issues did not receive any responses by the deadline, jeopardizing the solicitation’s future. The Texas grid operator announced on Dec. 31 that due to the lack of inquiries regarding the request for proposals, it will not be releasing answers or updates to the solicitation by the subsequent deadline on Jan. 8.
Seeking cost-effective solutions, ERCOT is exploring options beyond using CenterPoint Energy's mobile generators or committing to CPS Energy’s Braunig Units 1 and 2 through a reliability must-run (RMR) contract. Despite a previous response for the Braunig units, ERCOT is now considering an RMR contract with Braunig's largest gas resource, Unit 3, as staff work to address reliability concerns in South Texas. There are discussions about potentially relocating generators from Houston to San Antonio to provide a more economical alternative to maintaining the Braunig units.
