Holly to Seaholm Transmission Line
Summary
In January 1995, in response to safety and environmental concerns voiced by
neighborhood residents, the Austin City Council passed a Resolution directing
the Electric Utility to retire the Holly Street Power Plant in phases after
"completing the electric transmission system improvements needed to retire the
Holly Power Plant." The Resolution also directed the Electric Utility to
"Exercise due care in selecting transmission line routes in a manner that
minimizes the effect of the transmission lines to the citizens living in the
affected area." One of the improvements to the transmission system which is
required to facilitate the phased retirement of the Holly Street Power Plant is
the upgrade of the transmission line between the Holly Street Power Plant and
the Seaholm Power Plant from 69kV to 138kV. To comply with the Council's
direction in the Resolution, it was determined that a portion of the
transmission line would need to be rerouted.
Status
All transmission line construction on related distribution lines at the Rainey
Street yard, along Festival Beach Road and on Bergman Drive is in progress.
Design work on landscaping plan along the transmission route is underway.
Description
The approved overhead transmission line will exit the Holly Street Power Plant
site and turn southwest at the intersection of Bergman Avenue and Robert T.
Martinez, Jr. Street. The line then crosses the southeast corner of the lagoon
at Fiesta Gardens and turns west and follows the north shore of Town Lake to
IH-35. The line then turns north and runs along the east frontage road of
IH-35 to Lambie Street. The line turns northwest, crossing IH-35 and extends
to the southeast corner of River Street and East Avenue. The line turns west
and runs along the south side of River Street to the north shore of Town Lake.
The line continues west along the north bank of the lake, crosses Waller Creek
and connects with the existing transmission line near the Four Seasons Hotel.
The existing line continues along the north side of Town Lake crossing Congress
Avenue, South First Street and Shoal Creek before turning north and entering
the Seaholm substation. Major components of this project will pole
replacements, capacitor bank and autotransformer installation.
