NAESB Update Kathy Anderson October 2015 MIC Meeting

August 18, 2015 WEQ EC Meeting Request was to develop, modify, or delete business practice standards to support Request R14002 (NERC Project ATC Revisions (MOD A)) NAESB WEQ preserving NERC rejected ATC standards

August 18, 2015 WEQ EC Meeting The Business Practice Subcommittee’s recommendation contained two controversial standards, as follows: XXX-1.4 Each Transmission Service Provider shall not grant a request for Firm Transmission Service on an ATC Path that serves as an interface with another BA if the net of the Firm Transmission Service transactions into and out of the Transmission Service Provider’s BA would exceed the sum of the Facility Ratings of Tie Facilities to which Transmission Service Providers mutually agree they have the right to use the Tie Facilities that comprise the ATC Path, between the two BAs.

August 18, 2015 WEQ EC Meeting XXX Each Transmission Service Provider shall limit the Interchange Schedule (both Firm and non-Firm) of the reservations on an ATC path into and out of Transmission Service Provider’s BA on an interface with another BA such that the net Interchange Schedule does not exceed the sum of the Facility Ratings of Tie Facilities to which Transmission Service Providers mutually agree they have the right to use the Tie Facilities that comprise the ATC Path, between the two BAs.

August 18, 2015 WEQ EC Meeting The Independent Grid Operator (IGO) segment does not like these two standards and tried to get them removed. That attempt failed, so a compromise was crafted. Recommendation finally passed by the EC with agreement to form a new EC task force to address more fully these two standards.

Corrected WEQ for Resale off OASIS by eliminating the “no later than 24 hours prior” to confirming requirement. – The Assignee must execute a service agreement with the Transmission Provider that will govern the provision of reassigned service no later than twenty-four hours prior to the Assignee confirming the Resale on OASIS. the scheduling deadline applicable for the commencement of the reassigned service.

One conference call – Evident that non-consensus still exists Still waiting for FERC staff guidance Earlier this month, NAESB received word that internal to FERC, consensus on how to handle the conditional parent scenario has not been reached and was unlikely based on our informal request. As such, NAESB staff and WEQ leadership will proceed with preparing a filing of Version 3.1 of the WEQ standards. It is intended that the filing include a concise request for guidance regarding the conditional parent scenario. NAESB WEQ Firm Redirects from Conditional Parents Task Force Update
