The U.S. Wind Energy Production Tax Credit – time for a change

Report summary

The wind energy Production Tax Credit (PTC) has driven expansive development of wind power in the United States.  However, more recently the PTC has skewed wind deployment into areas that probably didn’t need it, while shortchanging other areas.  In some areas excess wind power is disrupting power markets.  With tax policy support scheduled to decline for both the wind and solar industries, a reasonable joint extension policy should recognize that they do not need perpetual support.
