Central Lincoln Reliability Project 17th & Holdrege to 21st &

Project update
The Central Lincoln Reliability Project remains on track, with design of
the overhead and underground portions completed and construction underway.
Here's an update on the project:
- To accommodate work on the city of Lincoln’s Antelope Valley Roadway
Project – and minimize the amount of new pavement that must be removed
and replaced to install the project's underground
duct
bank – LES last
fall expedited installation of a portion of the duct bank on 19th Street
between N and P streets. LES will install the rest of the duct bank as
originally planned in 2012.
- General Cable was awarded the contract to construct the underground
portion of the lines. To ensure coordination of
all entities affected by the project's construction, LES held a
preconstruction meeting with representatives of General Cable, the
University of Nebraska-Lincoln and City Public Works in February.
- Two local subcontractors were selected to construct the project's
underground
ducts. King Contracting will install the
bore under
Antelope Creek near 17th and Y streets. K2 Construction will install the
remainder of the underground ducts and
manholes.
- Construction of the underground line is scheduled to begin at three
locations in April: Antelope Park, north of 19th and Q streets, and 17th
and Y streets. Throughout the project, property owners will be notified
in advance of construction.
- The existing 12-kV lines have been placed underground on South
Street from Winthrop Road to 40th Street.
- The underground duct system is scheduled to be completed by fall
2012. General Cable will return in spring 2013 to install the 115-kV
cables in the duct.
- The contract for the overhead lines along South and 56th streets has
not been awarded. Construction on that portion is scheduled to begin
late July 2012.
- LES expects the Central Lincoln Reliability Project line to be
energized in fall 2013.
Overview
The project’s 115-kilovolt
line replaces an underground line installed 36 years ago and will connect
four
substations:
17th and Holdrege streets, a new substation at 21st and N streets, 30th and
A streets, and 56th and Everett streets. (See the map below.)
The new line is necessary to...
- Replace aging
cables.
- Meet the growing demand for electricity in central Lincoln.
- Improve system
reliability.
Approximately 63 percent of the route will be buried cable, and 37
percent will be overhead power lines. In
association with the 115-kV line being placed overhead along South Street,
the existing lower-voltage lines will be placed underground.
The
transmission line route was approved by the LES Administrative Board in
November 2010 after extensive input was gathered via three public open
houses, a customer survey, conversations with customers and numerous
meetings with public agencies and other stakeholders.
