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:

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.
