NOTICE DATE: November 16, 2017

NOTICE TYPE:  W-A092717-03 Operations

SHORT DESCRIPTION: Supplemental NSO Received for Barney M Davis Unit 1 (B_DAVIS_B_DAVIG1)

INTENDED AUDIENCE:  ERCOT Market Participants

DAY AFFECTED:  December 31, 2017

LONG DESCRIPTION:  On September 27, 2017, ERCOT received a Notification of Suspension of Operations (NSO) for Barney M Davis Unit 1 (B_DAVIS_B_DAVIG1) indicating that the Generation Resource would be decommissioned and retired on December 31, 2017. On October 19, 2017, ERCOT issued its initial and final determination pursuant to ERCOT Protocol Sections 3.14.1.2(3) and (5), indicating that the Generation Resource was not necessary to support ERCOT transmission system reliability, and that the Generation Resource could be decommissioned according to the schedule in the NSO (i.e., on December 31, 2017).

On November 16, 2017, Barney M Davis LP submitted a Supplemental NSO stating that the Generation Resource will be mothballed indefinitely, rather than decommissioned, according to the schedule set forth in the original NSO. This change in suspension status does not affect ERCOT's initial and final determination, and B_DAVIS_B_DAVIG1 may be suspended on December 31, 2017, in accordance with the supplemental NSO.

ADDITIONAL INFORMATION:  A copy of the supplemental NSO is posted under the Notice of Suspension of Operations portlet on the Grid/Generation<https://mis.ercot.com/pps/tibco/mis/Pages/Grid+Information/Generation> page of the ERCOT Market Information System (MIS) Secure Area.  An ERCOT Digital Certificate is required to access the MIS.
