For two reasons. First, we made a commitment to double our renewable energy capacity from 5% to 10% in 2007 as part of a 25-year Balanced Energy Plan to the Michigan Public Service Commission for meeting the energy supply requirements of our customers. Second, in 2008, Michigan passed a renewable energy standard requiring 10 percent of the state’s energy supply to come from renewable sources such as wind by 2015. We tapped our renewable energy portfolio because it’s the most economical approach, and offers the most value to customers. We’re also developing Cross Winds® Energy Park, a 250-megawatt project in the Thumb area and have contracts to buy about 300 megawatts of renewable energy capacity from third-party suppliers, the majority of which comes from wind.
