A subsidiary of Warren Buffett’s Berkshire Hathaway Energy has unveiled its plans to spend $3.5 billion to bring hundreds of new wind turbines online across the West over the next three years. PacifiCorp, which operates utilities that serve customers in six states from California to Wyoming, announced the plan as part of the 20-year resource plan for its subsidiary, Rocky Mountain Power. The company said the move was made to take advantage of federal tax credits for renewable energy development that are set to sunset in 2020. PacifiCorp’s resource plan includes bringing 1,100 megawatts of new wind power online in Wyoming by 2020, and replacing more than 900 MW of existing wind turbines in Wyoming, Oregon and Washington with newer, more powerful models. It also includes adding more than 1,000 megawatts of solar power. The projects will roughly double its renewable energy capacity. Construction for the upgrades and new transmission is expected to provide between 1,000 and 1,400 jobs in Wyoming and $80 million in tax revenue. Subsequent taxes for the new fleet will bring in $11 million per year starting in 2021, and state taxes on wind generation will kick in an additional $3 million annually by 2025, according to the company.
