RECOMMENDATION:
Close out the emergency action approved at the November 18, 2020 Board Meeting
related to the emergency procurement of transformer bushings for Martis Valley Substation
in accordance with District Code Section 3.08.100.
DISCUSSION:
Under contract with the District, NorCal Power Services (NCPS) performed equipment
testing for the major electrical apparatus at Martis Valley Substation in early November.
Unfortunately, the 120kV bushing insulators on the power transformers failed testing.
NCPS recommended immediate replacement of these bushings as they can fail
catastrophically. The General Manager declared an emergency situation per District Code
Section 3.08.100 on November 11th to expedite procurement and replacement of these
transformer bushings. The Board ratified this action at the November 18 th meeting.
Replacement bushings were ordered on November 16 th, arrived December 3rd, and were
installed on December 8th. During initial switching to return the station to service on
December 14th, staff discovered additional repairs were needed on the high voltage switch.
These repairs were performed on December 18th and the station was returned to service
on December 21st. The energization of Martis Valley Substation completes the work
associated with the emergency procurement and repair action approved at the November
18, 2020 meeting.
