The Story II Wind Energy Center, which began operation in December 2009, has an installed capacity of 150MW. The company will begin power deliveries to Google Energy on July 30, 2010 and will supply the remaining 36MW from the Story II Wind Energy Center to the city of Ames, Iowa.

According to EPA estimation, the company’s North American wind fleet that includes nearly 700 wind turbines in operation in Iowa with a nameplate capacity of more than 1,000MW and more than 9,000 wind turbines in operation at 77 wind farms in 17 states and Canada, has saved approximately 14 million tons of carbon dioxide emissions in 2009.

Mike O’Sullivan, senior vice president of development at NextEra Energy, said: “We are thrilled to welcome Google Energy to our growing list of customers and appreciate their support of emission-free, renewable energy.

“With the support of customers like Google Energy, we’ve built our wind fleet from fewer than 500MW a decade ago to more than 7,600MW – the largest fleet in North America today.”
