LONG DESCRIPTION: ERCOT
received a proposal from Brazos Electric for a new Special Protection System
(SPS) for the Whitney transformer. This SPS is intended to protect
against overloading on the Whitney 345/138 kV transformer that may occur with
the loss of the Bosque Switch – Elm Mott 345 kV Line and high dispatch of
345 kV generation at the Bosque Switching Station.
Upon completion of its review,
ERCOT has granted approval of the Whitney SPS. Information regarding SPSs
can be viewed on the ERCOT Planning and Operations Information secure
