The debate on US energy policy continues to rage. The reminder from Japan that nuclear reactors can, and sometimes do, have accidents is merely the worst of a number of examples in recent years about the risks and potentialities of various energy pathways. Coal mine and oil rig accidents do kill people and harm the environment; large scale biomass production for energy takes land and water from other uses (including baseline carbon sequestration), and can compete with food consumers as well; there is more natural gas than we thought, but there might be some negative surprises when we fracture bedrock to get it. In short: there is no free lunch, complicated systems break down, and what seems the best way forward can change quickly.
Against this backdrop, politically-directed subsidies to most forms of energy continue to escalate. To map the distortions, the U.S. Energy Information Administration is presently at work on an update to its earlier review of subsidies to the US energy sector. Their updated analysis is supposedly due out later this spring. Given that the EIA is the most respected government source of energy data, their subsidy data will again we widely read and cited.
Unfortunately, few specifics on the new analysis have been made public at this point. I've been told that Senator Lamar Alexander (R-TN) has again put in the request for the study and set the research terms. However, attempts to confirm this, and to get a copy of his actual request, have been met by a wall of silence from Conrad Schatte, Alexander's energy point person.
Past EIA Subsidy Numbers Have Suffered from Limitations in Their Research Mandate
I have been critical of past EIA reports (see here and here). Some of the Administration's simplifying assumptions and definitional rules have led them to exclude very large subsidy programs and to understate the magnitude and uncertainty of some of those they have included. As illustrated in the table below, this is not a small problem. Appropriate adjustments to their research scope and methods would have increased EIA's aggregate subsidy estimates by billions of dollars per year and greatly altered the relative subsidy shares to different fuels. Both absolute subsidies and relative shares of total support to oil, coal, nuclear would rise substantially. Absolute subsidies to wind would likely have been substantially higher as well, though aggregate support would have remained much lower than for conventional fuels.
One of the problems here is that at least some of these large omissions seem to have been driven by the allowable scope of research. These terms were set by Senator Alexander in his letter to EIA.
Because Alexander holds strong preferences for some forms of energy and animosity for others (hates wind, loves nukes, for example - see discussion after the table), there is some risk that the scoping of the research mandate can be shaped to support his desired outcomes rather than to neutrally assess the impact of subsidies. Because of this potential risk, the research mandate for EIA's current subsidy work be made public now, rather than just published along with the final study. Should there be gaps in their allowed work program that would again skew their results, at least there would be time to fill them without undue delays in the report's timeline.

' Going to War in Sailboats' and Lamar's other thoughts on our nation's energy future
Too often the federal government seeks to pick energy sector winners via targeted subsidies to favored fuels and industries. This approach is not one likely to achieve robust or efficient solutions, but appears to be a central element in the way Senator Alexander approaches energy markets.
The Senator is not shy about his preferences. Wind energy is "going to war in sailboats" according to a 2010 compilation of five addresses Alexander has given in recent years outlining his energy vision. True, the cover graphic is amusing, what with the brave soldier using his dulled sword to fight the bombers and all (Lamar couldn't even give the guy a musket?) But as a road map for our energy future, it leaves much to be desired.
The preface, written in early 2010, cites the numbers from EIA on the relative subsidies to nuclear versus wind based on the research criteria that Alexander himself crafted. The document notes:
At current rates of subsidy, taxpayers would shell out $170 billion to subsidize the 186,000 wind turbines necessary to equal the power of 100 reactors. While federal government loan guarantees should jump-start the first few reactors, the subsidy cost to taxpayers of building 100 reactors would be one-tenth as much.
A striking phrase contrast, to be sure -- if it weren't flat out wrong. EIA's study ignored all subsidies to new reactors if they weren't yet costing the treasury money (none were). Yet the 100 plants the Senator is pushing to build would clearly tap into that support in a big way. Alexander may believe that only the "first few" reactors would need loan guarantees, but there has not been any evidence to support such a conclusion, though much evidence to refute it. Lobbying expenditures spiked when loan guarantee programs were being formulated; and nuclear projects have been regularly cancelled when reactors were culled from the loan guarantee finalist list or term sheets came out that actually required appropriate premiums for default risks.
Alexander's research mandate to EIA also excluded an array of other important supports such as favorable accelerated depreciation schedules and caps on nuclear liability.
Specific clauses of concern in the 2007 research mandate include:
Look only at "energy-specific" energy subsidies..."Broad policies or programs that are applicable throughout the economy need not be considered." EIA interpreted this to exclude a wide range of energy-specific asset classes receiving special depreciation schedules if the Treasury didn't present those subsidies in a separate line item in its tax expenditure budget. Billions in tax-exempt bonds widely used for energy-related purposes were ignored as well since the same instruments were used for non-energy purposes. Subsidized bulk water transport, heavily used to move oil and coal, was also excluded. As noted in my critique, there are few bright lines here, and many of the provisions EIA included are also used by non-energy sectors.
Look only at subsidies "that provide a financial benefit with an identifiable federal budget impact." If all that one cared about here were budget outlays, this strategy might make sense. But Alexander clearly has a much bigger energy mission: to expand conservation and build 100 new nuclear plants. EIA, as well, is concerned with the impact of federal policy on broad energy market trends. Alexander notes that construction of his reactors should go ahead even if the government needs to make it happen "because conservation and nuclear power are the only real alternatives we have today to produce enough low-cost, reliable, clean electricity to clean the air, deal with climate change, and keep good jobs from going overseas."
There's no mention of using competitive energy markets, the price system, or pursuing the lowest carbon abatement strategies first. Rather, we should proceed based on the Senator's view of the optimal path. But political beliefs do not a vibrant market make, and others -- hardly anti-nuke partisans -- do not share his optimism for nuclear as the primary greenhouse gas abatement strategy. Exelon CEO John Rowe, for example, despite operating the largest fleet of merchant reactors in the country, found in 2010 (see PDF page 8) that new nuclear power plants were the fifth most expensive option. By last month -- though before the Japanese earthquake and tsunami -- new reactors had fallen further still in attractiveness, becomming their third most expensive option (see PDF page 11).
The limitation to "identifiable federal budget impact" excludes the large intermediation value of federal loan guarantees on high risk energy investments (valuable even if they don't default because they allow high risk enterprises to tap large amounts of low cost debt); increasingly large consumer subsidies triggered by the Renewable Fuel Standards; outlay equivalent values of tax breaks where the tax breaks themselves are not taxed; the provision of very expensive, high risk energy services (such as nuclear waste management) by taxpayers on a break-even basis at best, and with no built-in return on investment; and assuming energy-related trust funds that are running operating surpluses but actuarial deficits are not conveying subsidies.
Stipulation of what types of subsidies to include. The list of program types to review, provided by Alexander to EIA, included tax expenditures, direct expenditures, federal R&D, and federal electricity programs. It did not include federal credit and insurance programs not linked to federal electricity programs; government-owned energy service organizations other than electricity generators; tax-exempt organizational structures; and regulatory mandates such as the Renewable Fuel Standards that force consumers to buy specific goods and services at above-market prices. While EIA did touch on some of these categories, the report authors did not cover them systematically or in-depth last time around. The challenge is that some forms of support are very important for one type of energy and irrelevant for another. Thus, without systematic capture of all subsidy mechanisms, the relative subsidies by fuel will be highly inaccurate.
"The report should include an estimate of the size of each subsidy over a recent, representative year." This phrase may have been one factor in the decision for EIA to look at energy-related trust funds in terms of their operating balance rather than their long-term actuarial adequacy. Subsidized insurance programs or caps also need to be viewed over a long time horizon.
"If a valid methodology can be developed, a forecast of subsidy impacts would be very informative at well." This sentence seemed to give an opening to evaluate how subsidies now on the books are affecting marginal investment decisions; however, there was little detail in this area in EIA's 2007 report. Stan Kaplan, who did a great analysis of this issue while at CRS, is presently at EIA. This may be a sign that the distortionary role of subsidies on the country's energy path by skewing marginal investment decisions will be systematically addressed this time around. That would be a good thing.
Like favorite sports teams, affinity for particular energy types seems to run deep. Geography clearly plays a role: it is not surprising that Senators Tom Harkin (Iowa) and Richard Lugar (Indiana) have long been staunch supporters of biofuels, and corn ethanol in particular. The two have proposed increasing renewable fuel mandates to 60 billion gallons per year, a move that would result in more than a trillion dollars in subsidies to the biofuels sector over the policy's tenure. For wind energy, there is T. Boone Pickens who has proposed a surge in wind energy to free up natural gas for use in the transport sector (albeit not in our current vehicles which are unable to use natural gas), thereby eliminating the need for much of our imported oil.
Thus, it is hardly unexpected that nuclear power also has its cadre of boosters. What is interesting, however, is how often these folks tip their hats to France as the model for what the US should do. Senator Lamar Alexander (Tennessee) points to France as he advocates for building 100 new reactors in the country. Alexander, no fan of wind energy, refers to federal supports to the energy resource as "subsidizing sailboats," though assumedly all of his 100 reactors would sport shiny federal loan guarantees on their cooling towers in order to be able to attract financing.
Moving beyond generalities of energy independence through nuclear into actual data on the French program is not easy. There is much overlap between military and civilian operations, and the country has not had the degree of transparency on nuclear fuel chain economics necessary to evaluate the cost-efficiency of their nuclear bets. A handful of reports have begun to squeek out providing a broader picture of the French program. Turns out, the model has some flaws that ought to be taken seriously by the US boosters of adapting the approach here.
The most extensive body of work I've seen on the topic has been assembled by Mycle Schneider, an independent consultant and founder of WISE-Paris. His recentreports include a number of interesting findings. First, the French decision to complete reactors when other countries stopped construction due to poor economics led to overcapacity of baseload power in France. To boost usage, the French then subsidized electric heating -- a strategy that boosted aggregate demand, though exacerbated demand swings with heightened demand peaks. Because nuclear power plants must run fill tilt, following a variable demand curve was not something this fleet of reactors did well. As a result, France has had to export nuclear baseload cheaply, while importing peak energy at a much higher cost. The country has also brought back online a number of very old and polluting oil-fired generation stations to provide peak energy.
A second important finding from Schneider's work is that the impact of the nuclear power program on final energy demand has been quite modest, and that the bulk of final demand continues to be met by fossil fuels. He questions the idea that nuclear power was a useful strategy to deal with the issue of oil security, pointing out that only 12 percent of oil consumption in the country in 1973 was used in the electricity sector.
Schneider's "Beyond the Myth" paper also provides a useful review of the institutional framework for the French program, and highlights a number of circumstances where institutional structures have served to restrict rather than enhance program transparency. This history of opaqueness may be one reason why the recent relevations of potential safety problems have caused such a stir.
A second interesting paper, written by Arnulf Grubler of the International Institute for Applied Systems Analysis (October 2009), looks at the costs of the French nuclear program using previously unanalyzed cost data. Grubler finds that France reactor construction times lengthened considerably from an average of 63 months for the 1971-79 period (PWR Westinghouse license reactors) to 126 months for the 1984-1999 period (PWR new French design). He notes that the construction time for the Flamanville-3 EPR reactor submitted by French authorities to the IAEA (p. 16) was "entirely implausible," as it was a shorter time frame (and for a new design) than what had been achieved by nearly all prior reactors built in the country. He also finds that despite standardization, learning, and other factors that in theory can bring down unit construction costs, the French program instead showed real cost escalation over time (p. 25). Between 1974 and 1984, the real cost escalation was 5% per year. This increased to 6% per year from 1984-1990. The latest reactors in the period analyzed were roughly 3.5 times as expensive as the reactors built at the outset of the French program.
An important caveat is that these numbers pick up the cost of fuel chain facilities only through the price of fuel. In fact, however, the French government is itself a major player in those facilities, and these less visible portions of the fuel chain are believed to be heavily subsidized. This would further weaken cost trends from the French nuclear program.
A key justification of massive subsidies to reactor construction in the US is that they are merely transitional supports to help the industry through "first of a kind costs," but will no longer be needed once learning brings reactor costs down. The fact that not even the French saw declining real costs over time is indeed sobering.
A final critique of the French program worthy of mention was put forth by Yves Marignac, the current Executive Director of WISE-Paris, and another long-time analyst of the French program. In recent presentation in New York, Marignac points out that, similar to their US counter-parts, the French have not figured out a long-term solution for managing their nuclear waste; and that very substantial portions of the real costs of nuclear power remain hidden due to state involvement in the sector.
Will a less airbrushed view of the French program make Alexander, Graham, or McCain rethink the most appropriate policies for US energy strategy? Probably not. But it should.
