Wisconsin utility Madison Gas and Electric (MG&E) kicked off its "green pricing" scheme on March 13 with a "wind expo" in Madison after hitting customers with direct mail promotion from February 25. Customers are being asked to sign up for blocks of clean electricity worth $5. The quantity of power in each block will range from 80 to 120 kWh, depending on whether the wind plant to supply the scheme is completed in time to take advantage of the federal Production Tax Credit. The MG&E scheme is to be supplied with about 25 million kWh a year by an 11.2 MW wind farm of Vestas turbines. MG&E hopes to fully subscribe the program by the end of the year. Already, with little marketing, 2150 blocks have been sold to 1310 customers. Construction of the $15 million wind farm is underway. MG&E is acting as general contractor. The project is expected on-line by June.
