Pricing Interface Definitions

The Eastern reactive transfer interface definition will be revised on 5.19.2017 to coincide with the completion of eDART transmission ticket 620476. The revision will include the addition of the new Lauschtown-Hosensack 500 kV line and the removal of the TMI-Hosensack 500 kV line from the definition. The change is necessitated by the planned energization of the new Lauschtown 500 kV substation along the existing TMI-Hosensack 500 kV line.

The AP South reactive transfer interface definition will be revised on 10.7.2016. The revision will include the addition of the Bismark-Doubs 500 kV line and the removal of the Mt. Storm-Doubs 500 kV line from the definition. The change is necessitated by the planned energization of the new Bismark 500 kV substation along the existing Mt Storm-Doubs 500 kV line. The new AP South interface definition will be composed of:
  1. Bismark – Doubs 500 kV line  (previously Mt. Storm – Doubs 500 kV line)
  2. Greenland Gap – Meadow Brook 500 kV line
  3. Mt. Storm – Valley 500 kV line
  4. Mt. Storm – Meadow Brook 500 kV line

Special Protection Scheme (SPS/RAS) Installation/Removal

New North Hampton SPS/RAS
The new North Hampton SPS/RAS in Dominion zone (as discussed at the 1.10.2017 Operating Committee Meeting) will be implemented operationally on 4.16.2017.
Temporary Dominion RASPDF
Please see the following TEAC presentation (slides 9-27) for more information on the related Surry-Skiffes Creek project. TEAC Reliability Analysis UpdatePDF
Jenkins SPS/RAS Retirement
The Jenkins SPS/RAS has been retired due to the Jenkins 230 kV substation re-configuration; specifically Jenkins-Mountain 230 kV line was re-routed and is now the Jenkins-Mountain 230 kV line. Re-configuration work was performed as part of eDART transmission outage tickets 652451 and 652448. The SPS/RAS was originally installed to mitigate loading on the Susquehanna-Jenkins 230 kV line.
Bath County Stability SPS/RAS for Dooms-Lexington Outage
The Dooms-Lexington 500 kV line returned to service starting on 12.20.2016. As a result, the SPS/RAS is disarmed. The Dooms-Lexington line outage started on 10.23.2016 to complete the last phase of the line rebuild. The stability SPS/RAS was originally installed to address the impact of the long term Dooms-Lexington outage occurring in 2014 and 2015. The SPS/RAS will remain available for future use during emergent and planned outages.
Bath County Thermal SPS/RAS Retirement
The Bath County Thermal SPS/RAS to control for a contingency thermal overload on the Cloverdale 6A & 6B transformers will be retired on 12.1.2016. The scheme is no longer required and will be removed from service. Operationally, the SPS has not been used since 9.17.2016 coinciding with the start of the Cloverdale-Lexington 500 kV line outage to facilitate the retirement and replacement of the Cloverdale 6A & 6B transformers.
Cordova SPS/RAS Retirement
The Three-Phase Fault Unit Trip Scheme portion of the Cordova Energy Center SPS/RAS is planned to be retired by 12.15.2016. The Multi-Phase scheme, which trips the CTs, is no longer required and will be removed from service.
