TEAC Reviews Market Efficiency Timeline, Final for AP-South Endorsement

The Transmission Expansion Advisory Committee July 14 heard a number of forward-looking proposals and the final recommendations on the long-standing AP-South project.

Market Efficiency

During the Market Efficiency presentation, PJM presented the timeline for the 2016-2017 24-month market efficiency timeline.

The PJM Board will review the market efficiency input assumptions at its August meeting, and PJM will present the first draft of the 2016-17 base scenarios shortly afterward.

PJM plans to revise the assumptions after incorporating stakeholder feedback and input and publish the final versions in October, in time for the November Regional Transmission Expansion Plan window.

The presentation also included the final recommendations on the AP-South market efficiency project. The proposal from Transource Energy, LLC (an affiliate of AEP) is designed to alleviate congestion across the Pennsylvania and Maryland border.

The TEAC reviewed and discussed the AP South project at its May and June meetings. With the recommendation, PJM closes out the 2014-15 RTEP window. PJM will make its recommendation on AP-South to the PJM Board at the August meeting.

Reliability Analysis

The Reliability Analysis update included information on anticipated needs in the PSE&G zone and updates to several existing Dominion projects, among others. The update also included information regarding the current open window in the RTEP. The window opened late June with proposals due at the end of July.

Other TEAC presentations

PJM updated stakeholders on its presentation at the recent Southeastern Regional Transmission Planning meeting, noting that the presentation’s information had been presented to the TEAC previously.

Planning Committee Meeting

At the Planning Committee meeting earlier Thursday, stakeholders endorsed the load model to be used in the 2016 Installed Reserve Margin study.

PJM recommended an IRM-study load model that is consistent with the model used to produce the PJM load forecast each January.

Another factor in the selection was how accurately the load model reflected the historical load diversity between PJM and neighboring regions. The external regions included in the study model are MISO, NYISO, NEISO, the Tennessee Valley Authority and the VACAR South region (as defined by the North American Electric Reliability Corporation).

The committee also endorsed the periodic review of Manual 20: Resource Adequacy Analysis.

PJM presented an overview of details of the expiring PJM/NYISO Wheel Agreement. PJM has apprised the Operating Committee, Markets Implementation Committee and Planning Committee of the agreement’s status in their respective areas. PJM will continue to update stakeholders as the process progresses.
