EKPC Spurlock Area Line Changes

The Spurlock–Renaker, Spurlock-Stanley Parker, Spurlock-Stuart, and Spurlock-Meldahl Dam lines in EKPC zone are scheduled to be out of service in March and/or April 2019 under eDART tickets 797401 and 797407. These outages, in conjunction with tickets 701460 and 701476, are needed for clearance to relocate and decouple the double-circuited Spurlock - Maysville Industrial Tap 138 kV & Spurlock - Flemingsburg 138 kV line segments. The upgrade is under RTEP b2614 which has a required in-service date of June 1, 2019.

eDART tickets 797401 and 797407 are currently not “on-time” due to the timing of the outage submittal. In order to meet the RTEP in-service requirement date of June 1, 2019, these two tickets are marked as emergency outages under Manual-03 Section PJM is approving the outage requests associated with RTEP b2614 upgrade in order to complete the upgrade by the required in-service date. 2019 RTEP Status

PPL Siegfried Configuration

PPL is in the process of upgrading the Siegfried substation. The work is under a supplemental project to install a new GIS bus. As part of the upgrade, the Siegfried 230/69 transformers are also being replaced with new transformers. Once the new transformers are in service connected to the new 230 kV bus, the old transformers will eventually be removed from service and retired. The work at Siegfried are under various outages posted on the OASIS Outage Information page


AEP Facilities De-rates

AEP has performed a comprehensive review of its transmission facilities ratings within the PJM footprint and determined that certain facilities should be de-rated. Please see the list of affected transmission facilities below. The revised ratings will be effective on October 3, 2018. Please refer to the Ratings Information page for the current ratings in effect for all facilities including these de-rated AEP facilities.

Spurlock - Stuart & Spurlock - Meldahl Dam 345 kV Line Outages
The Spurlock - Stuart and Spurlock - Meldahl Dam 345 kV lines are scheduled to be out of service from March 20, 2018 to June 12, 2018 under eDART tickets 714775, 715816 and 715014. These outages are needed to reconductor a portion of the Stuart - Spurlock 345 kV line and to replace a wave trap in order to increase the line ratings. The upgrades are under RTEP b2879.1 and b2879.2, which have a required in-service date of June 1, 2018. The projects are expected to provide the rating increases as shown below:

Normal Emergency
Current Ratings 1240 1374

The Killen and Stuart owners notified PJM on March 20, 2017 of their plan to deactivate both plants on June 1, 2018. As a result, PJM performed deactivation studies and determined that several system upgrades are required. These upgrades are listed in the RTEP plan with the driver as generator deactivation of the Killen and Stuart plants. The PJM Board of Managers approved these upgrade projects on July 25, 2017. EKPC accepted construction responsibility for project b2879.2 on August 25, 2018 and subsequently submitted the required transmission outages to PJM in September 2017.

Due to the timing of the generation retirement announcement and the development of the planning criteria violation mitigation plan, the required transmission outages could not have been submitted in accordance with PJM’s on-time transmission outage submittal rules as outlined in Manual 3, Section 4. Therefore, PJM is approving the outage requests associated with the Stuart-Spurlock 345 kV line to expedite these particular system upgrades.
