ERCOT warns it may delay CPS Energy from closing gas-fueled power units

The operator of Texas' power grid — you know, the one GOP politicians keep assuring us is completely reliable — is warning that CPS Energy's plan to shut down some of its older, gas-fired power units could have a "material impact" on the grid's ability to deliver electricity. The Electric Reliability Council of Texas (ERCOT) raised the concern in Monday filing made in response to CPS Energy's plans. In the document, ERCOT officials said the San Antonio's city-owned utility would cut 859 megawatts of power output by closing the three oldest units at its Braunig Power Station, potentially threatening the grid's reliability.
