POWER Engineers has been awarded a contract to design, route and manage the construction of a nearly 220-mile transmission line across north-central Nebraska for the Nebraska Public Power District (NPPD).
The new 345 kV transmission line aims to enhance reliability, reduce system congestion and provide opportunities for the development of additional renewable energy projects on NPPD’s electric grid.
The line will be constructed from the existing Gerald Gentleman Station, extending north to a new substation in or near Cherry County, Neb., and then east to a new substation near the eastern border of Holt County. The new line may also require re-routing up to two miles of an existing 345 kV transmission line into the new substation near the Holt County line.
POWER will provide NPPD services related to preliminary engineering, route selection, environmental surveying, right-of-way acquisition, permitting, design engineering, structure and foundation design, electrical systems engineering and studies, surveying, and construction management services.
The proposed line is part of a 10-year transmission expansion plan approved in 2012 by the Southwest Power Pool, which is responsible for ensuring adequate transmission infrastructure in a nine-state region that includes Nebraska.
