Pitting Wind and Solar Against Nuclear Power

  • With US electricity demand stalled, expanding wind and solar power is increasing the economic pressure on equally low-emission nuclear power.
  • New state incentives for nuclear plants are facing resistance from the beneficiaries of renewable energy subsidies, as both battle for market share.
It's an old adage that a growth market has room for all participants, including new entrants. The US electricity market is now experiencing the converse of this, with increasing competition for static demand leading to headlines like the one I saw earlier this week: "Lifeline for Nuclear Plants Is Threatening Wind and Solar Power."

The idea behind that headline is ironic, considering that for more than a decade renewables have depended on government mandates and incentives to drive their impressive expansion. Along with recently cheap natural gas, they have made conditions increasingly difficult for established generating technologies like coal and nuclear power. In the case of coal, that was an entirely foreseeable and even intentional outcome, but for nuclear power it has come as a mostly unintended consequence.

Much as the slowdown in gasoline demand brought on by the recession created a crisis for biofuel quotas, stagnant electricity demand has hastened and  intensified the inevitable fight for market share and the resulting shakeout in generating capacity. US electricity consumption has been essentially flat since the financial crisis of 2008-9, thanks to a weak economy and aggressive investment in energy efficiency. More generation serving the same demand means lower prices for all producers, and fewer annual hours of operation for the least competitive of them.

At the same time abundant, low-priced natural gas from soaring shale production has made gas-fired turbines both a direct competitor in the 24/7 "baseload" segment that coal and nuclear power formerly dominated, and the go-to backup source for integrating more renewables onto the grid.

The US is essentially swimming in energy, at least when it comes to resources that can be turned into electricity. The only rationale left for the substantial subsidies that wind and power still receive--over $3 billion budgeted for wind alone in 2017--is environmental: mainly concerns about climate change and the emissions of CO2 and other greenhouse gases linked to it.

That's the same reason why some states have become alarmed enough by the recent wave of nuclear power plant retirements to consider providing some form of financial support for existing facilities. Nuclear power isn't just the third-largest source of electricity in the US; it is by far our largest producer of zero-emission power: 3.5 times the output of wind in 2016 and 22 times solar. A large drop in nuclear power is simply not compatible with the desire to continue cutting US emissions. Environmental groups like EDF are reaching similar conclusions.

Nuclear's scale is even more of a factor when it comes to considering what could replace it. For example, it takes the output of about 2,000 wind turbines of 2 megawatts (MW) each--roughly half of the 8,203 MW of new US wind installations last year--to equal the annual energy production of a single typical nuclear reactor. An infographic I saw on Twitter makes that easier to visualize:



I can appreciate why utilities and others that are investing heavily in wind and solar power might be convinced that providing incentives to keep nuclear power plants from retiring prematurely is "the wrong policy." After all, we have collectively pushed them to invest in these specific technologies, because it has been easier to reach a consensus at the federal and state levels to provide incentives for renewables, rather than for all low-emission energy.

As long as we are promoting renewables in this way, though, we should recognize that nuclear power is no less worthy. The biggest benefit of renewables is their low emissions (including non-greenhouse air pollutants,) an attribute shared with nuclear power. Yet because of their much lower energy densities, requiring much bigger footprints for the same output, and their lower reliability, incorporating a lot more renewables into the energy mix requires additional investments in electricity grid modernization and energy storage, along with new tools like "demand response." Nuclear power is compact, available about 90% of the time, and it works just fine with the existing grid.

By experience and philosophy, I'm a big fan of markets, so I would normally be more sympathetic to the view expressed by the American Petroleum Institute that states shouldn't tip the scales in favor of nuclear power over gas and other alternatives. However, we don't have anything resembling a level playing field for electricity generation, even in states with deregulated electricity markets. The existing federal incentives for wind and solar power, together with state Renewable Portfolio Standards, are already tipping the scales strongly in their favor. These subsidies will remain in place until at least 2022, consistent with the most recent extension by Congress. Why do renewables merit such subsidies more than nuclear power?

Wind and solar power are key parts of the emerging low-emission energy mix, and we will want more as their costs continue to fall, but not at the expense of much larger low-emission energy sources that are already in place. Less nuclear power doesn't just mean more renewables. It also means more gas or coal-fired power. That's the experience of Germany's "Energiewende", or energy transition.

As long as that is the case, and without corresponding incentives for equally low-emission nuclear plants, as well as for fossil-fuel plants that capture and sequester their CO2, we will end up with an energy mix in the next few years that is less diverse, less reliable, and emits more CO2 than necessary. I wouldn't consider that progress.

A Grand Compromise on Energy?

The idea of  a Congressional "grand compromise" on energy has been debated for years. A decade ago, such an agreement might have opened up access for drilling in the Arctic National Wildlife Refuge, in exchange for "cap and trade" or some other comprehensive national greenhouse gas emissions policy. By comparison, the deal apparently included in the 2016 spending and tax bill is small beer but still worthwhile: In exchange for lifting the outdated restrictions on exporting US crude oil, Congress will respectively revive and extend tax credits for wind and solar power.

Anticipation about the prospect of US oil exports seemed higher last year, when production was growing rapidly and threatening to outgrow the capacity of US oil refineries to handle the volumes of high-quality "tight oil" flowing from shale deposits. Just this week Michael Levi of the Council on Foreign Relations, citing a study by the Energy Information Administration, suggested that allowing such exports might now be nearly inconsequential in most respects.

Although little additional oil may flow in the short term, given the current global surplus, it's worth recalling that the gap between domestic and international oil prices hasn't always been as narrow as it is today. The discount for West Texas Intermediate relative to UK Brent crude has averaged around $4 per barrel this year, but within the last three years it has been as wide as $15-20. Oil traders will tell you that average differentials between markets are essentially irrelevant. What counts is the windows when those gaps widen, during which  a lot of cargoes can move in short periods.

No matter how much or little US oil is ultimately exported, and how much additional production the lifting of the export ban will actually stimulate, the bigger impact on the global oil market is likely to be psychological. Having to find new outlets for oil shipped from West Africa, for example, because US refiners are processing more US crude and importing less from elsewhere is one thing; having to compete directly with cargoes of US oil is going to be quite another. That's where US consumers will benefit in the long run, from lower global oil prices that translate into lower prices at the gas pump.

Finally, if OPEC can choose to cease acting like a cartel--at least for the moment--and treat crude oil as a normal market, then it's timely for the US to follow suit and end an oil export ban that originated in the same 1970s oil crisis that put OPEC on the map.

How about the other side of this deal? What do we get for retroactively reinstating the expired wind production tax credit (PTC), along with extending the 30% solar tax credit that would have expired at the end of next year?

We'll certainly get more wind farms, along with some stability for an industry that has been whipsawed by past expirations and last-minute extensions of a tax credit that has been a major driver of new installations throughout its 20+ year history. Wind energy accounted for 4.4% of US grid electricity in the 12 months through September, up from a little over 1% in 2008.

However, this tax credit isn't cheap . The 4,800 Megawatts of new wind turbines installed in 2014 will receive a total of nearly $2.5 billion in subsidies--equivalent to around $19 per barrel--during the 10 years in which they will be eligible for the PTC, and 2015's additions are on track to beat that. The PTC is also the policy that enables wind power producers in places like Texas to sell electricity at prices below zero--still pocketing the 2.3¢ per kilowatt-hour (kWh) tax credit--distorting wholesale electricity markets and capacity planning.

As for solar power, it's not obvious that the tax credit extension was necessary at all, in light of the rapid decline in the cost of solar photovoltaic energy (PV). In any case, because the tax credit for solar is calculated as a percentage of installed cost, rather than a fixed subsidy per kWh of output like for wind, the technology's progress has provided an inherent phaseout of the dollar benefit. Solar's rapid growth seems likely to continue, with or without the tax credit.

The big missed opportunity from a clean energy and climate perspective is that these tax credit extensions channel billions of dollars to technologies that, at least in the case of wind, are essentially mature and widely regarded as inadequate to support a large-scale, long-term transition to low-emission energy. I would have preferred to see these federal dollars targeted to help incubate new energy technologies, along the lines of the Breakthrough Energy Coalition announced by Bill Gates and other high-tech leaders at the Paris climate conference.

The current deal, embedded within a $1.6 trillion "omnibus" spending bill, must still pass the Congress and be signed by the President. It won't please everyone, but it is at least consistent with the "all of the above" approach that has been our de facto energy strategy, at least since 2012. It also serves as a reminder that despite the commitments at Paris to reduce emissions of CO2 and other greenhouse gases, renewable energy will of necessity coexist with oil and gas for many years to come.

A Cleantech Trade War with China?

While we wait to see whether the next big move in oil prices--and hence gasoline prices--is up or down from today's level of around $125 per barrel, two stories in today's Wall St. Journal highlight some of the challenges facing manufacturers of equipment used to produce renewable energy. One concerns the intention of the US administration to seek the World Trade Organization's assistance in easing China's restrictions on its exports of rare earth materials used in a wide range of devices, including wind turbines, hybrid and electric vehicles, and some solar panels. The other is an op-ed offering a solution to the looming trade war over solar panel and wind turbine tower exports from China, modeled on the 1996 Information Technology Agreement that lowered trade barriers in that industry. The two stories are related, reflecting major unintended consequences of the ways we have approached our transition away from fossil fuels and toward lower-emission sources of energy.

Trade wars are risky things, because you never know where they will lead. The classic example of this is the Smoot-Hawley tariff of 1930. It and the responses to it by other countries helped deepen and extend the Great Depression, and I have never seen any analysis of them that concluded they were a good idea. A major trade dispute now over renewable energy hardware and the ingredients needed to produce it looks doubly unwelcome, because none of the parties comes to it with clean hands. Much of China's output of rare earths is being consumed by China-based manufacturers producing permanent magnet wind generators, electric vehicle motors, compact fluorescent lights, and solar equipment, much of which is exported to global markets that owe their very existence to government interference in the form of manufacturing, deployment and consumer tax credits; government loans and loan guarantees; feed-in tariffs; and fuel economy and lighting efficiency standards. There's hardly a single aspect of the global cleantech industry that is the result of unaided market forces.

The US complaint about solar imports is a good example. I wouldn't be surprised if the US government can make a strong case that the Chinese solar firms in question benefited from government assistance in ways that constitute unfair competition under established rules of international trade. Yet the same US government has provided substantial assistance to US solar manufacturers in the form of direct R&D support and federal loans and loan guarantees, as well as indirect help in the form of solar investment tax credits, cash grants, and project loans and loan guarantees that helped create and sustain a domestic market for them. All of these were necessary, because despite the significant cost reductions these incentives facilitated, the output of solar panels is still substantially more expensive than electricity from conventional generation. If we win this round with China, do we open the door to a whole series of WTO complaints against us by others who could claim harm from our own renewable energy policies?

From my perspective, these trade issues are a symptom of the larger problem of global overcapacity in wind and solar equipment manufacturing that has been created by the complex interaction of a mare's nest of national and local incentives and support for the production and deployment of these technologies, amplified by the disruption caused by the global financial crisis and recession of a couple of years ago and the ongoing financial crisis in Europe. A vast industry was created out of nothing and handed a market through a set of policies that could not sufficiently fine-tune development to prevent the emergence of a boom-bust cycle, and that now appears to be unsustainable itself in light of developed-country deficits and debts.

Trade disputes are one possible mechanism for attempting to rationalize this overcapacity, but in my view they constitute a much less productive approach than the one suggested by Professor Slaughter, who if I understand his proposal correctly is urging the rationalization of the government subsidies that have caused this situation in the first place. My biggest concern about his advice is his choice of the UN climate negotiating process as the best body to pursue such an initiative. That might be an appropriate venue, but its recent history doesn't inspire much confidence that it is up to the task.

The Battle to Extend Wind Incentives

With the end of the year approaching, the annual Congressional debate over extending a variety of expiring federal tax credits and other benefits is gearing up again. Few of these measures are as high-profile as the payroll tax cut, but each has a vocal constituency, including renewable energy. The American Wind Energy Association (AWEA) has launched a major effort seeking inclusion of the Production Tax Credit (PTC) for wind power in this year's "tax extenders" package. That might seem premature, since the PTC won't expire until the end of 2012, until you realize that eligibility for the stimulus-funded Treasury renewable energy grants for which many wind project developers have opted over the PTC ends in a few weeks with little chance of a further extension. However, before simply tacking another year (or four!) onto a tax credit that began nearly 20 years ago, Congress should answer two basic questions: Is this still the most effective way to promote renewables like wind, and does wind power now require subsidies at all?

I don't blame AWEA for tackling this issue early, since the US wind industry has experienced significant volatility when previous PTC expirations went down to the wire, and in several cases lapsed for up to a year. At the same time, taxpayers deserve a more compelling rationale for continuing to subsidize wind power than the one now being offered. The "green jobs" argument is wearing thin, post-Solyndra, and it has become increasingly evident that helping to create a market for renewable energy technologies is a necessary but not sufficient condition to establishing a sustainable, globally competitive renewable energy manufacturing industry. Although more of the wind power value chain is now produced in the US than previously, too much of each wind subsidy dollar still goes offshore for this to be deemed an efficient way to boost to US jobs and manufacturing without reform.

In order to address the first question I posed, concerning the continued suitability of the PTC, it's important to understand how it works and how it compares to other renewable energy incentives. The current PTC provides wind project owners (or the parties to whom the tax benefit has been sold via a "tax equity swap") with an income tax credit of 2.2 cents per kilowatt-hour (kWh) of electricity actually generated and sold from the completed facility. Based on recent estimates of the levelized cost of electricity from unsubsidized wind power, that's over 20% of a typical wind farm's production cost. It's also equivalent to more than half of this year's average wellhead price of natural gas--a far larger subsidy per BTU than the controversial tax benefits currently provided to oil & gas firms.

The best thing about the PTC is that it is entirely outcome-based. You only receive the benefit when your project is completed, brought online, and as power is sold to customers. Mess up any of those steps and you get zilch. Put your project in a location with poor wind resource or limited access to transmission, and you won't get nearly as much tax benefit. So from that standpoint--ignoring the green jobs angle that arose mainly from expediency when the financial crisis and recession hit--we are getting what we pay for: actual low-emission energy. The structure of the PTC has cash-flow implications that are viewed as a problem by many wind developers but might be regarded as a useful feature by taxpayers. Smaller developers, in particular, have greater difficulty financing projects when the incentive must be deferred until after start-up, or they may lack sufficient taxable income to take full advantage of the credit. They complain about the need to transact swaps with bankers and other investors to realize the subsidy sooner, at a cost. But perhaps it's not such a bad thing for companies that small to have to convince an experienced third party that their project is really viable.

There are many alternatives to the PTC, including the 30% Investment Tax Credit (ITC), the same one received by solar and other technologies. The stimulus bill extended the ITC as an option for wind and allowed the Treasury Department to pay it as a cash grant, rather than waiting for subsequent tax filings. This certainly put money in the hands of wind developers much quicker--$7.6 billion since 2009 including $3.3 billion so far this year--and it has the added benefit of automatically scaling down as the cost of the technology falls. The solar feed-in tariffs favored in Europe didn't have such a feature, with the result that countries have had to cut them numerous times, but only after the fat tariffs gave birth to a huge export-oriented solar manufacturing industry in Asia. Similar competition is now emerging in the wind industry.

The main problem with the ITC is that when viewed from an outcomes perspective, which really gets to the question of effectiveness, the outcome being promoted is construction, rather than energy production. You would get the same tax credit for a project with the best wind resource as for one with the worst. (This has also led to a lot of solar installations in places that would never otherwise have been considered.) So of the two main policy tools the federal government has used to subsidize renewable electricity, the PTC is probably more cost-effective in delivering the result we should really want, which is more renewable energy. As it is, even with rapid growth over the last decade, wind accounted for just 2.8% of our power generation this year through August.

That brings us to the bigger question of whether wind should be subsidized at all after the current PTC term expires. I get emails practically every day from folks who have serious concerns about the health and environmental impacts of power, as well as its cost- and emissions-reduction effectiveness. Even if we ascribed all of these concerns to NIMBYism, it doesn't change the fact that the wind PTC, complete with annual inflation adjustment, is providing the same level of incentive as it did when the technology was much less mature and cost many times what it does today; AWEA cites wind costs having fallen by 90% since 1980. Other factors have also changed in the last twenty years. A majority of US states--and most of those with attractive wind resources--now have in place Renewable Portfolio Standards requiring utilities to include increasing proportions of renewable power in their supply. These mandates create a similar redundancy as the one between the ethanol blenders credit, which is also due to expire 12/31/11, and the biofuel mandates of the federal Renewable Fuels Standard. In the absence of the PTC, the state RPS system should provide a safety net--and more--for the industry.

There are two other key factors missing from AWEA's arguments for extending the PTC. The first is the economy, which is the main reason that US electricity demand has not been growing at a rate that would support large generating capacity expansions of any kind. New wind installations have been anemic for the last two years, in spite of last year's extension of the Treasury grants. Moreover, wind must now compete with the explosion of domestic natural gas production from shale, which when used in combined cycle gas turbines produces cheaper electricity than wind, with low emissions of the air pollutants that are of the greatest concern to most Americans, while still beating coal-fired power hands down on greenhouse gases.

Where all this leaves us depends on your priorities. If your main focus is on reducing greenhouse gas emissions and you see renewable power as a key strategy, then in the absence of a price on carbon you might support extending the PTC for at least a little longer. If you are concerned about climate change but more worried in the short term about the deficit, then letting the PTC lapse next year and relying on state RPS quotas to put a floor under wind looks reasonable. If boosting US cleantech manufacturing is your aim, you should prefer a more direct incentive than the PTC. And if your main worry is oil imports, then the PTC is irrelevant, since the US gets less than 1% of its electricity from burning oil, and most of that in remote and back-up power roles that wind can't easily fill. On balance, if after considering all the alternatives the Congress decides to extend the Production Tax Credit, it should be for an explicitly final period, at no more than the 1.1 cent/kWh rate that technologies like marine, hydropower and waste-to-energy now receive, and without the annual inflation adjustment that undermines the incentive to continue reducing costs.

Extend or Reform?

As the US Congress returns from its election recess to take up its "lame duck" session, one of many crucial pending items it will likely take up is the so-called "extenders" package: key tax provisions that are due to expire at the end of the year, unless extended by legislative action. From an energy perspective, this includes both the expiring ethanol blenders credit and the Treasury renewable energy grants issued in lieu of the investment tax credit (ITC) for renewables. Both incentives face a much more uncertain reception when the new Congress is sworn in next January, so the lame duck might just be their last gasp.

For the ethanol credit, that is as it should be; if 32 years of federal subsidies haven't made corn ethanol competitive with gasoline--particularly when its use is now mandatory--then nothing will. The situation for the renewable energy grants is more complicated. This is a relatively new benefit that, as I've noted in previous postings, was instituted as part of last year's American Recovery and Reinvestment Act--a.k.a. the stimulus--to substitute for a class of market transactions ("tax equity") that renewable energy developers could no longer access as a result of the financial crisis. Bridging that gap became all but essential for smaller companies without enough taxable earnings to take full advantage of the tax credit on their own, or lacking adequate working capital to afford to wait until their next tax filing to recoup the applicable ITC portion of the cost of a project.

If that situation still obtained, justifying the extension of the grants for another year or two would be easy. In the meantime, however, much has changed. Although not yet functioning at the same pace as before the financial crisis, the tax equity market is recovering. Banks and insurance companies have announced a growing number of tax equity deals in the last few months. This market might revive even faster if it weren't competing with essentially free money from the Treasury.

The other aspect of the situation that has changed is the growing dominance of large players in renewable energy project development, particularly for wind. Contrary to the perception that the Treasury grants mainly benefited small companies, more than half of the $5.4 billion in grants awarded to date went to just three companies, all of them large and profitable enough to have waited until tax time to collect their ITC benefits--though I don't doubt that getting cash up front improved the economics of their projects. For example, EDP Renovaveis, through its Horizon Wind Energy subsidiary, collected around $565 million in grants in the first half of 2010, after receiving "in excess of 685 million dollars" in 2009. Meanwhile, between its 3Q2010 earnings presentation and its 2009 full-year presentation Iberdrola Renovables claimed approximately $983 million in US renewable energy grants. NextEra Energy (the renamed parent company of Florida Power & Light) booked $556 million in grants in the first 9 months of 2010, on top of $100 million last year. All of this was entirely appropriate under the provisions of the stimulus, but it doesn't quite fit the picture of an emergency measure intended to help small, struggling firms.

Some have argued that in any case the grants are merely a matter of timing for the government: paying eligible developers cash now, or paying them the same amount later, via reduced taxes. That would only be true if every project that was eligible for a grant could (or should) proceed without one. Sparing wind farms, solar installations and other projects from the discipline of rigorous review by private investors risks allowing weaker projects to proceed, when they should either be rethought or cancelled. That was an unavoidable risk in early 2009, when the renewable energy industry was in peril of imploding, but overlooking it seems less justifiable today.

The Treasury renewable energy grants were instituted as an extreme step at an unprecedented time. It's hard to imagine that anyone intended them to become a permanent entitlement to replace the existing renewable energy tax credits, which were simultaneously extended through the end of 2012 for wind power and 2013 for most other technologies. However, if this program is to be extended for now, it ought to be reformed to exclude beneficiaries for which it constitutes merely a convenience, rather than a necessity. That would mean either capping the maximum payout for any recipient at something less than $100 million, or imposing a corporate income threshold. I'll be watching this issue with great interest between now and the end of the year.

A Wind Bubble?

New US wind turbine installations have slowed significantly this year, compared to 2009, and the decline is having consequences. Among other fallout, Suzlon is mothballing a four-year-old wind turbine factory in Minnesota and laying off the remaining 110 workers, due to a lack of new orders. While the industry pins most of the blame for the slowdown on insufficiently aggressive federal energy policies, it suddenly occurred to me to wonder whether wind power, like housing, might have been caught up in an investment bubble that has finally popped, somewhat belatedly.

The idea of a wind bubble goes against all conventional wisdom, including the importance of expanding electricity generation from low-emission sources in order to mitigate climate change; the desire to build a vibrant "new energy" economy in the US for energy security and competitive reasons; and the persistent mantra of the green jobs that are supposed to turn the economy around. Yet every bubble must have a compelling, plausible narrative, or it would never take off.

When you examine the charts of annual and quarterly US wind turbine installations on pages 2 and 3 of the "Third Quarter 2010 Market Report" from the American Wind Energy Association, there are at least two ways to look at them. The customary perspective would attribute the dramatic increase in wind installations beginning in 2006, which set records in each of the next three years, to the rapid scaling up of an industry that many envision supplying 20% of US electricity generation within two decades, up from its current level of around 2%. This growth has been supported by a variety of incentives and mandates, including the federal renewable production tax credit (PTC), the stimulus grants, and state renewable portfolio standards. But in this scenario it's hard to explain why installations would have fallen off so much this year, when all of these benefits are still in place, other than the imminent expiration of eligibility for the stimulus grants--which in another year might have been expected to trigger a mad rush for projects to get in under the wire, as we saw in 2008 when the PTC was due to expire at year end. How can we attribute this year's drop in installations to the absence of a policy--either a national renewable electricity standard or a comprehensive climate bill--that we've never had?

So turn this picture around and ask why wind might have been in a bubble, and why that bubble might have only popped now, roughly two years after the other bubbles for stocks, housing and possibly oil prices. Aside from the policies promoting wind and other renewables, which have not changed, wind power developers would have looked at two other indicators: credit and demand. Wind projects are capital intensive, and in the run-up to the financial crisis they benefited from the same kind of cheap and readily available credit as other businesses and homeowners did. At the same time, between 2000 and 2007 US demand for electricity was growing at about 1.3% per year. That might not seem like much, but at the scale of the US power sector, that translated into the need to add around 7,000 MW of new generating capacity each year. If all of that was from wind turbines, the required nameplate capacity would approach 20,000 MW, because of wind's lower average output per MW. Wind was also becoming a preferred technology, despite its intermittency, because coal was falling out of favor for environmental reasons and the price of natural gas, the fuel for the dominant incremental generation technology for the last 20 years, had spiked and become very volatile.

If wind was indeed being carried along either by its own bubble or by the froth from the other bubbles fueling the economy in the middle of the decade, why has it only now run out of steam, rather than popping in 2008 or 2009? After all, electricity demand growth evaporated when the financial crisis and recession hit, and demand has not yet recovered to its 2007 peak. For 2008, perhaps the dash to complete projects before the expected expiration of the PTC--it wasn't extended until October of that year--provides sufficient explanation. As for 2009, the charts show that installations did fall dramatically until the implementation of the Treasury stimulus grant program, which injected $1.7 B into wind projects last year and another $2.9 B this year. Moreover, the stimulus grants were more valuable to wind developers than the PTC they formerly received. That isn't just because developers got the money up front, rather than having to wait until a project started up and produced electricity, but also because the grants were based on the 30% investment tax credit (ITC). Using NREL's simplified calculator for the levelized cost of electricity, at a typical cost of around $2,200/kW of capacity the ITC could be worth at least 20% more than the 2.2¢/kWh PTC. In other words, just as the wind market was collapsing last year, the government increased its incentives and accelerated them into up-front cash. That might have been enough to keep a bubble going for a while longer.

Of course there's no way to know whether this scenario is more accurate than the standard explanation for what has happened to the US wind market this year. Nor does it doom wind power to the doldrums even after the economy resumes growing and creating jobs at a healthier rate, and electricity demand picks up. However, if there is a grain of truth in this view, then it might alter our perspective on providing more aggressive support for the wind industry based on the notion that installations should still be running at 10,000 MW per year or more, as they were in 2009, rather than at the lower rate of around 5,000 MW we see today.
