What is the name of Berkshire Hathaway's energy utility holding company?

Berkshire Hathaway's energy utility holding company is Berkshire Hathaway Energy.

The business was formerly known as MidAmerican Energy Holdings Company. Berkshire Hathaway acquired control of MidAmerican in 1999, making energy one of the conglomerate's major operating areas alongside insurance, railroads and manufacturing.

The company changed its name to Berkshire Hathaway Energy in 2014. Its portfolio includes PacifiCorp, MidAmerican Energy Company, NV Energy, Northern Powergrid, natural-gas pipelines and renewable-power businesses. That makes it broader than a single electric utility: it is a collection of regulated utilities, transmission operations, pipelines and energy projects.

A common mix-up is confusing Berkshire Hathaway Energy with one of its subsidiaries, especially MidAmerican Energy or PacifiCorp. NextEra Energy, Duke Energy and Dominion Energy are separate publicly traded energy companies, not Berkshire Hathaway's utility holding company.
