IEP has detected a trend on Brighton 6A 500kV CB loss of Brighton T1 500/230kV transformer is exceeding 90% of LTE. Study opening Brighton 6A and 6C 500kV CB for contingency control. Coordinate implementing the switching solution if it does not bring up thermal constraints on other parallel paths.  Prior to implementing the switching, study opening each breaker individually to not switch into an actual on the Brighton 6A or 6B CB. 

To control the loading on the Juniata - Cumberland 2355 230kV line, study and consider implementing the switching solutions listed below:

The Prince George 230/115kV TX1 is trending on post-contingency basis. Dominion can SCADA switch the Prince George - Poe 115kV line though the switching is limited to a 4 hour duration without opening the line disconnects. If the switching is required for an extended period of time, discuss the option of sending switch personnel and opening line disconnects. Dominion will evaluate the feasability of the long term switching, which will include evaluating increased risk to load loss. If the Prince George - Pie 115kV line is opened, whether for 4 hours or for extended duration, Dominion will need to submit an eDART ticket or the EMS Trip Ticket will need to be converted to a Pre-Contingency Switching ticket.
