ERCOT summer reserve margins lowered to 7.4%, vs reliability target 13.75%
Gibbons Creek 470 MW coal generation plant notified ERCOT that it will mothball plant prior to summer 2019.
Gibbons Creek attributes;
- ~22 miles east of College Station
- Built 1983, 36 years old
- ERCOT Houston zone
- Operated summers only since 2016
- Been for sale since 2016
- Owned by Texas Municipal Power Agency who is owned by Cities of Bryan, Denton, Garland, and Greenville, TX
This will lower ERCOT summer reserve margin from 8.1% to 7.4%, as compared to ERCOT reliability target of 13.75%.
Subject to changing ERCOT market rules, summer power prices are going to be volatile.
