"Many wind projects are planning to come on line before the end of 2012, in advance of the possible expiration of a federal incentive, the wind production tax credit (PTC). It appears that wind developers are pushing to complete projects in 2012 to qualify for the PTC. Under current law, projects that begin operating prior to the end of 2012 are eligible to receive a 2.2-cent PTC for each kilowatthour of generation over a 10-year period. Similar behavior in the face of previous PTC expirations was discussed in an earlier Today in Energy article describing the history of the wind PTC. EIA collects monthly updates on modifications, retirements, and additions to the nation's fleet of power plants, including the planned date of commercial operation for new generators."
