Increasing commodity costs, the weakening U.S. dollar and government mandates spurring demand all have driven up construction costs of wind farms, the Northwest Power and Conservation Council was told Tuesday.
Costs for other kinds of power plants also increased, said Jeff King, a senior resource analyst for the council.
In addition, representatives from two Northwest utilities and the Bonneville Power Administration reported that Northwest dams don’t have enough flexibility remaining to supplement and smooth the intermittent power supplies generated by new wind farms.
