MidAmerican Energy Holdings Co., the power unit of Warren Buffett’s Berkshire Hathaway Inc., agreed to buy wind turbines valued at more than $1 billion from Siemens AG for five projects in Iowa, in the supplier’s biggest order to date for land-based wind equipment.
Siemens will provide 448 of its 2.3-megawatt turbines with total capacity of almost 1,050 megawatts, enough to power about 320,000 households, Munich-based Siemens said today in a statement.
