MidAmerican Energy Holdings Company describes itself as a global leader in the production, transportation and delivery of energy from a variety of fuel sources, including coal, natural gas, wind, hydro, solar, nuclear, geothermal and biomass.

MidAmerican

It is the unlisted power arm of Warren Buffett’s Berkshire Hathaway Inc. (NYSE:BRK.A) (NYSE:BRK.B). The company was in the news yesterday for the huge order it placed on Siemens AG (NYSE:SI) (FRA:SIE) for the supply of 448 wind turbines, each capable of generating 2.3 megawatts.

The order, estimated to be worth over $1B, will enable MidAmerican to add over 1000 megawatts to its generation capacity, to be distributed across various locations such as the O’Brien, Webster, Grundy, Madison and Marshall counties.

Renewable energy business

MidAmerican Renewables is the arm that generates energy from renewable sources. According to the corporate brochure, MidAmerican Renewables has committed to invest over $7B in new wind and solar projects. It is building two of the world’s largest photovoltaic solar projects – Topaz Solar Farms and the Antelope Valley Solar Projects I and II, and has a total of 2,285 megawatts of owned wind-powered generation capacity.

Its MidAmerican Geothermal subsidiary owns a 50% interest in 10 geothermal facilities in California’s Imperial Valley that have the capacity to produce up to 327 megawatts. It also owns and operates or has a stake in several natural gas-fueled plants across the country.

The MidAmerican Hydro unit owns 50 percent of the 10-megawatt Wailuku hydroelectric generation project, which is located at the junction of the Wailuku River and the Kalohewahewa Stream on the eastern coast of the island of Hawaii. Electricity generated is sold to the Hawaii Electric Light Company, Inc.

Investment strategies

MidAmerican entered solar generation in 2011 when solar panel prices were at lows due to massive global oversupply. Warren Buffett also justified his foray into the solar business in a letter to shareholders as follows:

“MidAmerican will have 3,316 megawatts of wind generation in operation by the end of 2012, far more than any other regulated electric utility in the country. The total amount that we have invested or committed to wind is a staggering $6 billion. We can make this sort of investment because MidAmerican retains all of its earnings, unlike other utilities that generally pay out most of what they earn. In addition, late last year we took on two solar projects – one 100%-owned in California and the other 49%-owned in Arizona – that will cost about $3 billion to construct. Many more wind and solar projects will almost certainly follow.”

The Siemens wind turbine order we mentioned above is, similarly, savvy capex ordering. Markus Tacke, chief executive officer of Siemens Energy’s wind power division, said, “The U.S. is leading the way toward grid parity,” which is the cost point at which the cost of generation from a renewable source is the same as that from a non-renewable source such as coal.
