MidAmerican Energy Moves Forward with New Transmission Line Construction in Humboldt and Kossuth Counties

DES MOINES, Iowa – (Sept. 11, 2014) – Preparations are underway on a new transmission line being constructed by MidAmerican Energy Company. On Aug. 19, the Iowa Utilities Board approved an approximate 120-mile 345-kilovolt transmission line that will run from O’Brien to Kossuth to Webster counties in northwest Iowa, much of which will follow an existing 161-kilovolt transmission line route.

Residents in Humboldt and southern Kossuth counties will begin to see construction activity on the new transmission line as early as mid-September. Excavating equipment, boom trucks and other construction equipment will be seen on roads and along transmission line easements while crews begin foundation construction for the new, self-weathering steel 345- and 161-kilovolt structures. The new single-pole structures will replace the existing two- or three-pole structures, which means there will be fewer poles per mile resulting in more land being available for farming. Construction of two new substations will begin in Kossuth and O’Brien counties, in addition to work that is already underway to expand an existing substation in Webster County that is located at the end of the line’s route. Construction activity is estimated to be complete by November 2016, and the transmission line is anticipated to be in-service by year-end 2016.

“As we begin work on the project, we remind residents and landowners in the area to stay safe and be aware of construction activity,” said Jeff Gust, vice president of compliance and standards for MidAmerican Energy. “We also want to thank everyone involved in the planning process, including landowners, county officials and the communities welcoming the project – thank you for your support.”

The project is designed to improve the electric grid system reliability by helping relieve transmission congestion, allowing for regional delivery of renewable generation, like wind, and ultimately helping lower the cost of delivered energy. In addition to the grid system improvements, the project will create economic benefits to local communities, including landowner easement payments, an increase in annual property tax payments to local counties, construction jobs, and future renewable energy possibilities.

In 2011, the Midcontinent Independent Transmission System Operator, Inc. board of directors unanimously approved the organization’s Transmission Expansion Plan 2011. The plan is a comprehensive long-term regional plan for the electric grid that will benefit energy consumers throughout the Midwest. MidAmerican Energy will assist with the construction of four of 17 Multi-Value Projects included in the MISO plan. The transmission line being constructed in Humboldt and Kossuth counties is part of Multi-Value Project 3.
