The fraying of support for wind power’s PTC subsidy

Michael Giberson

The coalition in support of  wind power’s Production Tax Credit has always had a bit of a “Baptists and Bootleggers” flavor: environmentalists making a clean and green argument in favor of wind power and the multinational wind power development corporations funding the political muscle needed to get things done. The coalition has proven durable even as wind power took a few environmental hits, but now the business side of the coalition is beginning to fray. The Production Tax Credit will expire at the end of 2012 unless Congress acts to extend it.

One example: The Chicago Tribune reports that Exelon Corp., a large electric power company that owns a significant amount of wind power and a member of the American Wind Energy Association, is opposing efforts to renew the tax credit (reg. required).

“The (production tax credit) has been in place since 1992, I believe,” Exelon Chief Executive Christopher Crane said in a conference call with investors and analysts Wednesday. “And I think that’s enough time to jump-start an industry, 20 years.”

The economic logic behind Exelon’s position is clear: “with nearly half of its profits coming from its nuclear fleet and low-cost wind power cutting into its margins, Exelon is in Washington leading a fight to kill a tax credit the wind industry says is crucial to its survival.” Note that “low cost wind power” is referring to the low marginal cost of production, not the total cost per MWh of energy produced. Most of Exelon’s generating assets are in markets with energy prices driven toward the marginal cost of production, and additional wind power in these markets tends to push average prices down.

It isn’t just the nuclear fleet that sees its profitability pushed down, either. Wind on wind competition is also becoming an issue. If additional wind power comes online near existing wind power, it naturally produces more output at the same time that existing wind power plants produce more output. The profit-suppressing effect of new wind is thereby intensified for existing wind assets.

Wind power project owners contemplating PTC extension have to weigh the benefits from anticipated new projects against the price suppressing consequences for their existing wind power and other generation assets. It is a cost-benefit weighing that is increasingly turning against continued support for the PTC among owners of wind power assets. Of course, on the other hand, manufacturers of wind power turbines and towers, and those developers who build but don’t own wind power projects benefit only from the construction of new projects. Wind power coalition dynamics should see these players taking a bigger and bigger role over time.

The Chicago Tribune article contains more good stuff. They found someone willing to claim that wind power needs the subsidy because it is “on the cusp of seeing real price declines,” and “In three to five years wind energy will be cost competitive … without the subsidy.” The claimant doesn’t explain why we shouldn’t just wait three to five years and build wind power when it is actually competitive.

(Research efforts do seem to be making progress in improving wind power productivity. That progress justifies maybe a few million dollars for continued research, not a few billion dollars to build more not-quite-cost-competitive wind power projects now.)

  1. “wind power … is “on the cusp of seeing real price declines,” and “In three to five years wind energy will be cost competitive … without the subsidy.” ”

    I call bull$#;+. Wind power has no technological upside. None. There can be no source of cost reductions. NONE.

    Worst of all the real cost of wind is the 70% of the time that the capital is sitting not generating electricity or revenue, and the cost of the back-up fossil fuel systems that are necessary to allow the grid to function and be stable.
