W-A083018-03 Implementation of system change to correct error related to NOGRR174


NOTICE DATE: August 16, 2019

NOTICE TYPE: W-A083018-03 NOGRR

SHORT DESCRIPTION: Implementation of system change to correct error related to NOGRR174

INTENDED AUDIENCE: ERCOT Market Participants

DAY AFFECTED: August 28, 2019

LONG DESCRIPTION: The full implementation of Nodal Operating Guide Revision Request (NOGRR)174 resulted in violation notices for Automatic Voltage Regulators (AVR) and Power System Stablilizers (PSS) tests being erroneously displayed for Generation Resources in the Net Dependable Capability and Reactive Capability (NDCRC) application. ERCOT intends to correct this issue by implementing a system change on August 28, 2019, to prevent violation notices for AVR and PSS tests from being displayed in the NDCRC application.

NOGRR174 was fully implemented on June 1, 2019, as described in the previous Market Notice linked to below.

ADDITIONAL INFORMATION: NOGRR174 and associated documents can be found on the ERCOT website.

Please review the ERCOT website for previous Market Notices related to this subject.
