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

to 30th & A to 56th & Everett
Project update
The Central Lincoln Reliability Project remains on track, with design of
the overhead and underground portions completed and construction underway.
See the progress map.
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.
Throughout the project, property owners will be notified
in advance of construction.
LES expects the Central Lincoln Reliability Project line to be
energized in fall 2013.
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.
