Company profile

MidAmerican Energy Company is an American energy company headquartered in Des Moines, Iowa. Formed in 1995, it is a subsidiary of Berkshire Hathaway Energy, which is, in turn, a consolidated subsidiary of Berkshire Hathaway Inc. As a rate-regulated utility, MidAmerican Energy employs approximately 3,400 people. The company serves over 1.6 million electric and natural gas customers across Iowa, Illinois, Nebraska, and South Dakota.

The company's operations involve the generation, transmission, and distribution of electricity and natural gas. MidAmerican Energy maintains a diverse energy generation portfolio, incorporating renewable resources such as wind and solar, alongside on-demand sources like coal, natural gas, and nuclear power. It claims to operate more wind generation capacity than any other investor-owned utility in the United States, with over 3,500 turbines in Iowa by the end of 2025. Additionally, the company provides various energy efficiency programs to its customers.

In terms of patent litigation, MidAmerican Energy Company appears as a defendant in its single tracked case. This posture indicates the company is an operating entity defending against an assertion, rather than an entity primarily engaged in patent assertion. The case is filed in the Southern District of Iowa.

The company's sole tracked litigation, Midwest Energy Emissions Corp. et al. v. Berkshire Hathaway Energy Company et al., lists MidAmerican Energy Company as a defendant alongside its parent company, Berkshire Hathaway Energy Company. This suggests the litigation may relate to broader operational or technological aspects within the Berkshire Hathaway Energy family of businesses.
