MidAmerican Energy Company is a subsidiary of Berkshire Hathaway Energy.
MidAmerican Energy was formed in 1995 by the merger of the Iowa-Illinois Gas and Electric Company with Midwest Resources. Midwest Resources in turn, was formed in 1990 by the merger of Midwest Energy and Iowa Resources. Midwest Energy was the holding company for Iowa Public Service company (IPS), the main power provider for northwestern Iowa, while Iowa Resources was the holding company for Iowa Power and Light Company, the main power provider for central and southwestern Iowa.
Walter Scott, Jr. Energy Center
MidAmerican Energy is the developer and operator of the Walter Scott, Jr. Energy Center, a four-unit coal-fired power plant based in Council Bluffs. It produces more than 1,600 megawatts of electricity.
In addition to traditional power plants, MidAmerican Energy began investing in green energy generation in 2004. As of March 2014, approximately 2,285 megawatts, or nearly 30 percent, of MidAmerican Energy’s total owned generation capacity came from energy generated by the company’s 1,267 wind turbines. In May 2013, MidAmerican Energy announced plans to invest up to $1.9 billion to expand its wind generation fleet and add up to 1,050 megawatts of wind generation in Iowa by year-end 2015. Siemens Wind Power, the manufacturer of the turbines, states that at the time (December 2013) this was the largest single order of onshore wind power turbines that any company had ever received. Components for the turbines are manufactured at two different sites in Iowa and Kansas, and all turbines are to be sited in Iowa. Once the expansion is complete, approximately 3,335 megawatts, or approximately 39 percent, of MidAmerican Energy’s total owned generation capacity will come from wind-powered generation from 1,715 wind turbines. MidAmerican Energy projects that wind power will supply one third of its energy generation by 2020.
