Construction Commences on New MidAmerican Energy Transmission Line in Black Hawk County

DES MOINES, Iowa – (Sept. 11, 2014) – Progress is being made on a new electric transmission line being constructed by MidAmerican Energy Company in Black Hawk County. On June 26, the Iowa Utilities Board approved a 345-kilovolt transmission line from Waterloo to Dunkerton in northeast Iowa, much of which will follow an existing 161-kilovolt transmission line route.

Construction crews have started installing the foundations for the new, self-weathering steel 345-kilovolt 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. The assembly of steel poles will begin in late September. In addition, an expansion of an existing Black Hawk substation is underway, and electrical equipment will continue to arrive at the substation until year-end. MidAmerican Energy expects to complete work on this section of transmission line by the end of the year.

“As the project progresses, 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 Black Hawk County is part of Multi-Value Project 4.
