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.
