Electric Transmission


In December 2011, the Midcontinent Independent 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 bring more than $2 billion in annual benefits to energy consumers throughout the Midwest.

The projects in the MISO plan are primarily designed to deliver reliability to the Midwest region and provide effective and efficient transmission solutions to meet expected growth in renewable energy generation.

MidAmerican Energy Company will assist with the construction of four of the plan’s 17 transmission projects. MidAmerican Energy’s portion of the project will affect 12 Iowa counties and four Illinois counties.
