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
RTEP b2879.1 1240 1532
RTEP b2879.2 1466 1710

Background

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.

For questions, please email Transmission Operations or call (610) 666-8289.

February 4, 2015 - Keystone #3 500/230 kV Transformer
Keystone #3 500/230 kV transformer was out of service due to a relay operation on 11.3.2014. The transmission owner is still assessing the cause of the relay operation. For the duration of Keystone #3 transformer outage, PJM will take the following actions:

  1. Increase reserve requirement to cover the potential loss of Keystone #1 and #2 units (loss of the Keystone #4 500/230 kV transformer will result in the loss of both Keystone units);
  2. Activate the single contingency loss of Keystone #4 500/230 kV transformer, Keystone #1 unit, Keystone #2 unit, Juniata-Keystone (5004) 500 kV line and Conemaugh-Keystone (5003) 500 kV line.

The Keystone #3 transformer outage may impact the off-cost operation of BED-BLA transfer interface. Transmission owner has identified the cause for the relay operation which took out or service the Keystone #3 500/230 kV transformer. Required repairs and testing to restore the Keystone #3 transformer are expected to be complete by Thursday, February 5, 2015.

On Friday, February 6, 2015 Keystone #3 500/230 kV transformer has been fully restored back in service; and hence single contingency simulating loss of Keystone #4 500/230 kV transformer, Keystone #1 unit, Keystone #2 unit, Juniata-Keystone (5004) 500 kV line and Conemaugh-Keystone (5003) 500 kV line was disabled.
