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.
