A nearly 80-mile high-voltage regional transmission line that links southeastern Iowa and northeastern Missouri is now operational, including a 29-mile section that MidAmerican Energy constructed in three southeast Iowa counties.
The project provides a new major pathway for wind energy generation in areas along the route.
The 345,000-volt overhead transmission line, called Multi-Value Project 7, connects substations in Ottumwa, Iowa and Adair, Missouri, which is east of Kirksville. The line was energized on June 30.
On May 31, MidAmerican Energy completed its section of MVP 7, which runs through Appanoose, Davis and Wapello counties.
The 79-mile line was jointly constructed by MidAmerican Energy, ITC Midwest and Ameren Transmission Company.
In addition to improving transmission access for wind energy generation, the project helps relieve congestion on other high-voltage transmission lines and helps increase efficiency on the electric grid by reducing energy production costs.
“We expect that this transmission line will open up new channels for wind energy generation, lower wholesale prices for electric energy and help lower the costs of producing electricity to meet customer demand,” Dehn Stevens, general manager of MidAmerican Energy electric operations, said.
The transmission line projects create several economic benefits, including added grid interconnection and future interconnection options, landowner easement payments and county property tax payments. The projects, through modernized engineering, also reduce the number of poles and amount of needed land.
In 2011, the Midcontinent Independent Transmission System Operator Inc. approved a long-term regional energy grid enhancement plan, comprised of 17 multi-value projects. The MISO projects provide consumers with access to renewable energy and other low-cost electricity generation sources throughout the Midwest, and improve grid reliability and efficiency.
MISO is the independent transmission organization for all or parts of 15 U.S. states and Manitoba, Canada.
Since 2014, MidAmerican Energy has assisted with four projects, building approximately 252 miles of 345-kV transmission lines.
