First Wind to Sell Solar Power From Utah to Buffett Unit

First Wind Holdings Inc., a Boston-based renewable-energy developer, has agreed to sell power from seven Utah solar farms to a utility owned by Warren Buffett’s Berkshire Hathaway Inc.

Four solar farms planned for Beaver County and three for Iron County will sell power to PacifiCorp, a subsidiary of Berkshire Hathaway, First Wind said today in a statement. Construction is expected to begin later this year and end by mid-2015.
