Work underway on South Sioux City transmission line

January 20, 2012

South Sioux City, Neb. – Foundation work is currently underway on the south route of Nebraska Public Power District’s South Sioux City 115,000-volt Transmission System Expansion Project.  The setting of poles and stringing of transmission lines will continue throughout the spring and summer.

The $20.5 million South Sioux City project consists of two transmission line segments – one known as the south line route and the other as the north line route. NPPD’s Board of Directors awarded the construction contract this past November to Brink Constructors, Inc, a third generation family-owned electrical contractor with over 60 years of experience in construction of high-voltage transmission lines.

The construction contract is for approximately $5 million dollars.  NPPD has worked with Brink on numerous projects in the past, including emergency storm restoration work and is currently constructing the Axtell to Kansas 345kV transmission line.

The south transmission line route will run from the existing Twin Church substation (located west of Dakota City) east to the new South Sioux City substation (located along C Avenue between South Sioux City and Dakota City), spanning approximately seven miles. The north line route, approximately 10 miles in length, will also start at the Twin Church substation and generally head north into South Sioux City, east across State Route 77, and then follow the railroad tracks south and eventually connecting up with the same new South Sioux City substation.

NPPD has obtained 100% of the easements along the south route and is now working to obtain easements on the north route over the next few weeks.

“Barring any major weather delays we anticipate construction to be completed and the system to be operational by the end of the year,” NPPD Senior Project Manager Craig Holthe said. NPPD will use 94 steel poles and 167 wood poles along the two new transmission lines.

“The cooperation of the many landowners we have worked with has been excellent. Success of all projects like this by NPPD includes all parties working together to build long term relationships,” Holthe commented.

As noted earlier, foundation work began this month and is expected to be completed in late April. Erection of poles for the project is scheduled to begin in February.
