SHORT DESCRIPTION:
Proposal to disable the Whitney SPS
INTENDED AUDIENCE: ERCOT

DESCRIPTION: ERCOT has received a request to permanently disable
the Special Protection System (SPS) at Whitney. This SPS is intended to
relieve loading on the Whitney 345/138 kV Autotransformer for the loss of the
Bosque – Elm Mott 345 kV Line. The exit strategy for this SPS was
the installation of a second 345/138 kV Autotransformer at the Whitney
substation. The second autotransformer has since been installed. The
owner of the SPS believes it can be permanently disabled and ERCOT is
currently reviewing this proposal.
Further details of the Whitney SPS can be found in the
“Special Protection Systems Information” section of the ERCOT
