SWEPCO: Controlled Power Outages

SWEPCO has prepared a Fact Sheet (SEE DOCUMENT BELOW) to better explain the recent Controlled Outages (Rolling Blackouts) ordered by our regional grid operator, Southwest Power Pool (SPP).

This was an extraordinary event, ordered to protect the integrity of the grid and eliminating larger long term outages.  Our grid includes 14 states and stretches from Louisiana to the Canadian Border.  Correct management of our grid eliminated the issues we are seeing our neighbors in Texas experience with their in-state grid managed by ERCOT.  SWEPCO’s Texas Service Areas in Texas are part of the SPP Grid and excluded from ERCOT.

One thought on “SWEPCO: Controlled Power Outages

  1. Its awfully concerning that through all the hurricanes,tornadoes and other disasters we have been through we have never had to go through a “rolling blackout”. Why now? Why do this when we have senior citizens who can’t help themselves by getting to someplace that has power. In the most important time we need power ever this happens. Seems kind of strange to me this is going on now. Never in my 45 years here has this happened.
