NextEra Energy, North America’s largest wind and solar operator, expects wind turbine prices to continue dropping sharply in the years ahead, leaving the levelised cost of wind power at good US sites at a highly competitive $20-$25/MWh even after the production tax credit (PTC) expires for good.

In order to get there, however, NextEra says it will continue to lump pressure onto its turbine suppliers, asking them to pass along much of the corporate tax benefits they are likely to see from the recently passed US tax bill.
