DESCRIPTION: ERCOT has received a request to disable the Special
Protection System (SPS) at the Oncor Sandow Switching Station (Oncor SPS
#40 and #43). SPS #40 protects against overloads on the Sandow – Minerva
138 kV line. SPS #43 protects against overloads on Sandow – Taylor,
Sandow – Elgin and Elgin – Gilleland 138 kV lines. Oncor believes
that all transmission upgrades necessary to exit these SPSs will be completed
by the end of May.
The request to disable these
SPSs is being reviewed by ERCOT, as described in the SPS Approval Procedure.
Comments on the proposed SPS disabling are due by April 29, 2010, and should be
submitted to [log in to unmask] using the
attached comment form. Any questions or concerns raised during this timeframe will
be addressed by ERCOT staff or the entity submitting the SPS proposal.
Further details on these SPSs
can be found in the “Special Protection Systems Information”
section of the ERCOT Planning and Operations Information secure website: http://planning.ercot.com/login/login.
