The Electric Reliability Council of Texas (ERCOT) on Jan. 29 self-reported to the Public Utility Commission of Texas that it accidentally violated rule that require it to provide daily public disclosures of certain ancillary service offers.
ERCOT also notified the commission of its violation of a section of the ERCOT Protocols which requires ERCOT to promptly notify the market upon receiving notice that the owner of a mothballed Generation Resource expects to return the unit to commercial operations.
As for the mothball notice issue, ERCOT wrote: “On October 6, 2014, CPS Energy submitted a Notification of Suspension of Operations to ERCOT for Braunig Unit 2 (BRAUNIG VHB2), an ERCOT-registered Generation Resource, placing the Resource on mothballed status beginning January 4, 2015. On January 6, 2015, ERCOT received a Notification of Change of Generation Resource Designation (NCGRD) stating that CPS Energy intended to return Braunig Unit 2 to operational status on February 10, 2015.”
ERCOT said it didn’t issue the proper notices about this and has updated its NCGRD procedures to ensure this error does not occur again.
The GenerationHub database shows Braunig Unit 2 as a gas-fired steam unit with a net summer capacity of 230 MW.
