    Does the U.S. still face a severe natural gas supply crisis during the remainder of this decade?

    If there is any remaining doubt regarding this issue, it should be thoroughly dispelled by the National Petroleum Council’s recent Report to Secretary of Energy Spencer Abraham.

    The Council’s Report, entitled “Balancing Natural Gas Policy – Fueling the Demands of a Growing Economy,” presents the results of the most comprehensive assessment of supply and demand of natural gas in the North American market undertaken in many years. To date, it has received surprisingly little attention – despite Alan Greenspan’s warning last May regarding the potential threat to the U.S. economy posed by tighter-than-expected natural gas supplies. Anyone who reads the Council’s Report carefully, however – and I would urge everyone who reads this article to do just that -- can’t help but come away from the experience shaken. (The Report is available on the Council’s web site at www.npc.org.)

    The Council’s last assessment of the U.S. market, completed in December of 1999, was one of the few government or privately-sponsored studies that offered any substantial basis for believing that it would be possible to significantly expand North American supplies of natural gas above 1999 levels. It also provided the basis for many of the assumptions used by the Energy Information Agency (EIA) in its subsequent annual forecasts of supply and demand in the U.S. market. As such, it played an important role in justifying decisions by power plant developers to build more than $ 100 billion in new gas-fired generating units over the past four years – foregoing the opportunity to construct a more diversified portfolio that relied more heavily on coal-fired generation and renewable energy.

    Soon after the Council’s 1999 Study was published, however, production from some of the most important natural gas basins in the U.S. and Canada (particularly the Near Shelf region in the Gulf of Mexico and Canadian fields in Alberta) began to decline at an alarming rate. This in turn raised significant questions regarding the continued validity of many of the assumptions on which the 1999 Study was based.

    As a result, in March of last year, Secretary of Energy Spencer Abraham asked the Council (an advisory group the sole purpose of which is to advise the Secretary on issues pertaining to supply and demand of petroleum and natural gas) to undertake a comprehensive new assessment of the North American market. To help improve the accuracy of this assessment, the Secretary and other participants provided substantially greater funding and stronger technical support than had been made available in 1999. The Council’s new Study, which reflects the results of 18 months of intensive effort, includes a comprehensive, region-by-region assessment of likely future production for every major basin in the U.S. and Canada. This assessment, in turn, is based upon intensive interaction with the producers in each basin, to attempt to develop realistic estimates of future production for each field.

    The results of this reassessment are stunning and warrant urgent attention at the national level. They give notice of a potentially severe crisis during the next 10 years that will not be eliminated even if Congress immediately enacts the federal energy legislation about to be sent to the floor of both Houses. In its new Study, the Council begins by noting that, by 2002 (i.e., less than 36 months after the 1999 Study was issued), North American production already had fallen 6 BCf/day below the Council’s forecast for 2002.

    The Council concludes, however, that this inability to achieve the production levels previously forecast by the Council will not be a one time event.

    Instead, it reflects the inevitable result of the maturation and increasingly rapid aging of most major fields in the U.S. and Canada. This rapid aging has resulted in flat or declining production in many of the most important basins in both the U.S. and Canada and, as a practical matter, can not be reversed.

    As a result, the Council concludes that, with each passing year, North American production is likely to fall increasingly further behind the Council’s earlier projections. The Council’s new Report estimates that, by 2015, North American production from “traditional U.S. and Canadian sources of supply” (defined by the Council to include every basin south of the Arctic Circle) will fall an almost unfathomable 21 BCf/day short of the levels the Council had concluded would be necessary to meet the needs of the U.S. market when it issued its earlier Study less than four years ago.

    This equates to a drop in expected production, compared to the Council’s earlier estimate of expected production by 2015, of more than 7.5 Trillion Cubic Feet per year – i.e., a downward revision of more than 22% in less than 48 months.

    In BTU equivalent terms, the effect of this steep reduction is to create a hole in expected U.S. energy supply equivalent to more than 1.5X the amount oil the U.S. currently imports from Saudi Arabia (which is currently averaging a little over 1.8 million barrels/day).

    The Council bases this unprecedented downward revision in its earlier forecast on a combination of:

    • A significant reduction in its estimate of reserves in the U.S. and Canada that are technically capable of being developed;
    • A far more rapid than-expected drop-off in production from existing fields in both the U.S. and Canada; and
    • A dramatic decline in the size of new wells in both the U.S. and Canada.
    Based upon these factors, the Council concludes that even at prices as high as $ 8.00/MMBTU ($ 2002) there is only very limited potential to expand production in most major fields in the U.S. and Canada; production from many basins inevitably will decline.

    While the Council’s focus is principally on long-term supply and demand, the implications of its findings for the adequacy of natural gas supply in the North American market during the next 10 years are deeply disturbing.

    Even if the proposed Alaskan natural gas pipeline ultimately goes forward, it will not be completed for at least a decade; further, as much as the additional supplies it brings are needed, if and when it goes into service, it still will offset less than 21.5% of the shortfall in production identified in the Council’s Report.

    Further, the Council’s new estimates do not include any contingency factor to allow for the potential that its new estimates will prove to be too optimistic.

    This, too, should give cause for significant concern.

    As a result of the rapid aging of most U.S. and Canada fields, the Council already has been forced to reduce its estimate of future production levels by more than 22% in less than 48 months. Given the trend line, there obviously can be no guarantee that this year’s downward revision will be its last.

    Instead, if anything, given the continued declines in production that have been occurring during the past year (despite higher than expected prices and a high rate of drilling of new wells) further downward revisions in expected North American production may be likely to occur – with the potential that the decline rate could accelerate rapidly over the next several years.

    The Council did find that, under some scenarios, assuming much higher prices than the Council previously had thought would be necessary, it might be possible after an extended period to achieve a modest increase production from the lower 48 states compared to this year’s sharply reduced levels. To do so, however, would: i) require prices well above $ 5.00/MMBTU in $ 2002; (ii) take several years to achieve; and (iii) require a series of policy changes and other heroic measures that are relatively unlikely to occur (e.g., opening up for development areas that currently are restricted for drilling, significant speed-up in deepwater drilling in the Gulf, etc.). Further – and just as significantly -- even if all of these conditions are met, the Council estimates that, at most, these efforts would be unlikely to expand U.S. production to a level more than 1.0 BCf/day higher than the levels of U.S. production achieved three years ago, before production began to rapidly decline. (During this same period, the Council expects production from Canada at best to be flat.)

    This miniscule increase in U.S. production, even if achieved, will offset only a small portion (i.e., less than one year) of the growth in power sector demand for natural gas expected to occur over the same period.

    The Council also concluded that assuming that: (i) construction of the proposed Alaskan pipeline goes forward on an all-out, fast track basis with no impediments to prompt completion; and (ii) a number of other significant policy changes are adopted (e.g., fast-track permitting for new LNG terminals), by some time during the next decade, the massive supply deficit identified in the Report can be partially offset by bringing natural gas from the Arctic Circle into the lower 48 states and by major increases in the amount of Liquefied Natural Gas (LNG) imported into the U.S.

    In addressing these longer-term solutions, however, the Council’s focus was primarily on long-term supply and demand. This focus on long-term solutions is consistent with the Council’s mandate from Secretary Abraham, which was to examine supply and demand of natural gas through the year 2030. In the interim, as the Council emphasizes in its Report, North American demand still is expected to grow at a rapid rate, due primarily to the expected increase in the amount of natural gas used to generate electricity in the U.S.

    This expected increase is likely to be particularly steep starting in 2004 and continuing throughout the next 7 to 10 years, since natural gas-fired generating units are currently the only source of supply available to meet the incremental electricity needs of the U.S. economy during this period.

    Even if the Alaskan pipeline is started immediately and LNG imports ultimately become one of the primary sources of energy supply for the U.S., therefore (as the Council’s Report envisions), a huge gap still will remain between the maximum supplies that realistically are likely to be available to the U.S. market during the middle and later part of this decade and the projected needs of the U.S. economy over the next 7 to 10 years.

    A Decade of Crisis
    We believe that this near-term supply deficit is potentially the most serious problem facing the U.S. economy during the remainder of this decade.

    A Study recently completed by our firm, to be released in December, attempts to quantify the size of this supply deficit and identifies steps that can be taken to respond to this deficit. The Study concludes that, absent prompt implementation of the specific steps proposed in our study, for the U.S. economy to continue growing, it will be necessary to increase supplies of natural gas available to generate electricity by at least 3.39 TCf/year by 2010 and by at least 5.19 TCf/year by 2014:

    Table 1
    Increased Power Sector Consumption of Natural Gas

    * This estimate assumes normal summer temperatures in both 2003 and 2004 and normal growth in the economy. Given the mild weather that occurred this past summer (discussed in the text below) and the recent high growth rate of the economy, a much larger year-over-year increase in power sector consumption of natural gas is nearly certain to be required over the next 12 months compared to this year.

    Taking into account potential growth in residential and commercial demand for natural gas, the total increase in the amount of natural gas per year needed to meet the needs of the U.S. economy could be even greater – viz., as high as 5.3 TCf/year by 2010 and 6.4 TCf/year by 2014.

    The National Petroleum Council Study demonstrates beyond a shadow of a doubt that the supplies required to meet these projected needs won’t be available. Instead, absent aggressive steps to reduce the amounts of natural gas needed to meet the needs of the U.S. economy during this period, a massive shortfall is inevitable.

    Indeed, in the very near term (i.e., between now and 2006 or 2007), it has become increasingly clear that there is not likely to be any net increase in the supplies of natural gas available to the U.S. market (i.e., zero growth in net supplies, after taking into account the net impact of flat or declining U.S. production, modest near-term increases in imports of LNG, declining imports from Canada and expanding exports to Mexico). This is a startling prospect, since the increased supplies of natural gas needed to sustain the growth of the U.S. economy over the period between now and 2007, including likely increases in residential and commercial demand, could easily reach 1.5 to 2.0 TCf/year.

    This is an unprecedented shortfall in supplies. And it is likely to last not just for one or two years. Instead, as the amount of natural gas needed to generate electricity continues to grow every, the deficits will continue to mount, since we are unlikely to be able to ramp up imports of LNG rapidly enough to keep pace with growing power sector and residential demand for natural gas until, at the earliest, the mid to later part of the next decade.

    The basic contours of the crisis we’re facing, therefore, are unmistakably clear.

    Why then is there still no sense of urgency regarding the potential threat to the U.S. economy posed by this huge shortfall in expected supplies of natural gas over the next 7 to 10 years?

    Flaws in the Convention Wisdom
    Part of the reason there isn’t a greater sense of urgency regarding the crisis we face clearly is that, even though severe price spikes have occurred in two out of the past three winters, the period in which the supply crunch is likely to be most severe – with the most extreme prices – has yet to occur (although it could begin as early as next year).

    As a society, we’re seldom very good about addressing serious problems in advance – even when the dimensions of the problem are crystal clear and go straight to the core of our economy.

    A second reason is that the most powerful segments of the oil and gas industry, in their public advocacy efforts, have tended to focus primarily on supply options addressed to our long-term needs (e.g., the proposed Alaskan pipeline, expanded offshore drilling and steps to increase imports of LNG).

    This, too, is understandable, since at this point in the maturation of the industry opportunities for development in the lower 48 States are limited. The most attractive opportunities for new development, therefore, typically involve more distant sources of supply that often require government approvals to go forward and will take many years to develop. A third, equally important factor, however, is that (at least in my judgment) many of the best private forecasters and Wall Street equity analysts specializing in the oil and gas industry – bright people whose work often can be very helpful – aren’t yet interpreting properly the sweeping changes that have occurred in the natural gas market and instead continue to publish every week analyzes of what is happening in the U.S. natural gas market that are far off the mark.

    The result of the continued dissemination of these mistaken analyzes (however well intentioned) has been to perpetuate – and, over the past few months, perhaps even intensify – three pervasive myths regarding the natural gas market:

    Myth # 1: The near universal belief that the larger-than-expected injections into underground storage that occurred this summer were due to large-scale reductions in industrial demand that occurred this spring and early this summer.

    Myth # 2: The closely-linked belief that last summer’s experience demonstrates that natural gas prices above $ 6.00/MMBTU are not sustainable and instead will quickly result in large reductions in industrial use – which in turn will rapidly bring prices back to more “normal” levels.

    Myth # 3: The belief that, as long as the amount of working gas injected into underground storage exceeds 3,000 Billion Cubic Feet (BCf) (a benchmark that now has been substantially exceeded for this coming winter) reserves in storage are likely to be sufficient to meet winter needs and severe price spikes are unlikely to occur.

    These three beliefs are the cornerstone of the how many observers still look at the natural gas market. As recently as 1999 or even 2000, there still was a substantial basis for holding these views.

    As we’ll see momentarily, however, despite the frequency with which these claims are repeated, they clearly and demonstrably are no longer true today, in a market the fundamentals of which have irrevocably changed over the past 36 months.

    Instead, all of the larger-than-expected injections into storage that occurred this summer can be explained based upon decreases in the amount of natural gas used to generate electricity compared to the same months last year, not fuel switching by industrial users or other industrial demand destruction as so many analysts contend.

    Much of this reduction in the use of natural gas to generate electricity is weather related – and therefore not likely to be repeated.

    Further – and just as importantly – over the next 12 months, as the population continues to grow and the economy continues to expand, the amount of natural gas consumed to generate electricity is nearly certain to continue to increase dramatically – and then to continue increasing every year for at least the next 7 to 10 years (i.e., the minimum lead-time necessary to build new coal-fired capacity and/or to ramp-up imports of LNG sufficiently to begin to offset the increased natural gas requirements of the power industry).

    Contrary to the assertion that is often made, therefore, there was no structural change in the natural gas market this summer that “eliminated” or even materially reduced the likelihood of a natural gas crisis in future years. Instead, to the contrary, as we’ll discuss below, we dodged the bullet this summer far more narrowly than most of us realized at the time.

    If temperatures this summer had been more like the summer of 2002 and/or the resurgence in the economy that began in August had begun just 60 or 90 days earlier, we might well have seen $ 8.00 to 10.00/MMBTU natural gas prices this summer (i.e., during the time of year when natural gas prices historically are at or near their lowest point for the year).

    Further, while the sharp drop in the use of natural gas to generate electricity that has occurred over the past six months and the continued mild weather this fall have made it possible to build up larger storage reserves heading into this winter than might have been true under other circumstances, and thus reduced the risk of severe price spikes this winter, depending upon the severity of the weather this winter, before the winter is over, we still could see price spikes this winter that are just as severe as last winter, if not worse.

    How could this be? How could the conventional wisdom be this far off? And how could so many well-intentioned analysts have missed almost entirely the huge reduction in power sector consumption of natural gas that occurred over the past several months?

    And if the evidence of a long-term crisis is so overwhelming, why have natural gas prices softened significantly since they reached the $ 6.00/MMBTU level this past June? Quite frankly, as we’ll see, the issues involved are not subtle and are not difficult to assess fairly definitively. Instead, to the contrary, the relevant facts are obvious and indisputable.

    Why then do the three myths persist?
    At least part of the reason may be that all three myths have a certain seductive quality: they suggest that there is no crisis or, alternatively, that if there is it will “solve itself” painlessly, with higher prices quickly driving sufficient industrial demand out of the market to bring prices back down to levels consumers can tolerate.

    This seductive quality, however, is as dangerous as it is appealing.

    As long as the three myths continue to be treated as credible, we are likely to continue to delay taking the specific actions required to reduce the threat we face during the remainder of this decade as a result of drastically-lower-than-expected supplies of natural gas.

    Delay, however, is a luxury we can not afford. The costs ultimately will be far too high: literally tens of billions of dollars of avoidable energy costs over the next 10 years, hundreds of thousands of lost jobs and the potential to seriously retard the growth of the U.S. economy. It may be fairly important, therefore, to understand why each of these myths is false, since until we do we are likely to continue putting off actions that are essential to preserve the health of our economy over the next 10 years.

    Man, this is EXACTly my worst fear. I've been watching BP's anual evaluations of world petroleum resource status for several years now (a group I have a lot of respect for), and their predictions match this exactly. I've got a brother who contract managed gas fields in northern Alberta for years, a nephew who's an engineer for TCPL, a friend who does wildcat gas well drilling in Alberta. This matches what I've been hearing anecdotally between the lines all along. My gut reaction is I believe this about 80 - 90% certainty. The '99 spike in supply was just a blip caused by the new TCPL north-south line into the US midwest, but they've already got pipes up into the Cdn artic. They're looking hard and not finding it easy.

    So what now? What odds something like offshore gas hydrates could do it? Any other unconventional supplies? One group has proposed a bridge across the bering straight using the ice-bridge technology on the PEI - New Brunswick bridge . Looks like it should work, and Russia's got 2/3 the remaining world resources.

    At US$10+ / MMBTU, my present house isn't woth a nickel in Canada. People will walk away from such inefficient homes. Others up here will freeze to death.

    Any odds southern US would shut down their Air Conditioning to help out?

    Looks like we'd better start figuring out how to replace gas electric gen with Coal / Wind / Nuclear right away. How does a Nat. Gas turbine operate on coal gassifier ouput? Let's start that one right away fast, then make it illegal to burn Nat. Gas for electric gen, buy out the investors, convert what can be to producer gas or water gas now. Before we have to start figuring out how to pump carbon monoxide into homes as heating fuel. Yech.

    Actually, there was no need to wait this long for the "rebuttal" to the NPC's original study. The EIA, sponsored by no less than 6 industry trade groups, did a study of its own immediately following the release of the NPC's original "30 Tcf by 2010" forecast. The trade groups were concerned about the acceleration in decline rates which had become more pronounced over the latter half of the 1990's.

    The resulting study was titled "Accelerated Depletion: Assessing Its Impacts on Domestic Oil and Natural Gas Prices and Production". In it, the EIA ran at least a dozen cases using varying assumptions around price, decline rates, access to areas that were currently off limits to drilling, technology advances, etc. In only one instance did it conclude that the 30 Tcf scenario was realistic. In that one, drilling activity had to ramp up and remain strong, technology had to drive finding and development costs down at an increasing rate, and off limits areas had to be opened up to development by now. So, basically, there was ample reason not to accept the original NPC base case as gospel when it was issued 4 years ago. Keep in mind that it was a report produced by a committee of very powerful companies, not an independent, unbiased look at the industry.

    The EIA had its own political reasons for downplaying the issue - gas was the fuel of choice and considered the one petroleum based product the environmentalists would accept.

    Those who use scenario planning when developing business strategy, especially those in the petroleum industry who owned the wells that were depleting so rapidly, definitely considered the likelihood that the bullish forecasts weren't real. That's one of the reasons why they were lukewarm about investing millions in expanding gas plants and pipelines. The power developers had their own agenda, other people's money, and a consultan'ts forecast that gas would be $2 forever.

    So the warning signs were there back in 2000, but as was said a long time ago, "there is none so blind as he who will not see".

    I definitely agree with the article, and with Mr. Gould's thoughts about using gas for power generation.

    At a minimum, we should not be using gas for centralized, baseload power generation. Continuing to use gas for peaking power makes sense, because this is a task that only gas (or oil) does well, due to practical as well as economic issues. Also, using gas for "more intelligent" applications like distributed generation or co-generation should also continue (indeed, be encouraged) because, once again, these are appliations that only gas does well. These applications also have additional benefits, like relief of the grid and enhanced overall efficiency (due to the use of waste heat). In fact, increasing gas costs may actually encourage the use of gas in these applications.

    On the other hand, simply using gas for large-scale, centralized, base load power generation, when other sources like coal or nuclear are well suited to the task, is simply a waste of a precious resource. This is especially tragic when one consideres all the applications that require gas and nothing else (such as chemical feedstock applications, in addition to the peak power, distributed generation, and co-generation applications discussed above).

    One would hope that this problem is one that would resolve itself through economic feedback. Even at current prices of ~$5/MBTU, using gas for base load is already uneconomic. On the other hand, we seem to have an excessive short term focus problem on Wall Street, which seems to lead to bizarre economic decisions (such as continuing to choose gas for base load).

    Whereas I agree with the article in general, I was disappointed that Mr. Weissman only mentioned coal (and perhaps renewables) as an alternative, and did not mention nuclear. Another option, as an alternative to conventional coal, is IGCC coal (i.e., a gas turbine plant run on gassified coal). Both of these alternatives (nuclear and IGCC coal) are somewhat more expensive (~1 cent/kW-hr) than conventional coal, but their environmental impacts are a tiny fraction of those from conventional coal plants. I'm assuming that the (somewhat) higher cost is the reason why Mr. Weissman did not consider these two alternatives.

    As the article suggests, future gas supplies will be limited, and we will not be able to continue to rely on gas for most of our new generation. Whereas we've reached the point where renewables (especially wind) are ready to make a significant contibution, they are limited by their intermittant and diffuse nature, and are also not able to provide all (or even most) future power. Thus, a significant fraction of our future generation will have to be conventional coal, IGCC coal, or nuclear.

    Whether we choose conventional coal, or the other two (much cleaner) alternatives boils down to how much we care about environmental/public health issues. I personally believe that the extra one cent per kW-hr is clearly worth it. This is especially true given that most studies that quantify the external costs of conventional coal plant pollution estimate the costs (of premature deaths, medical costs, ecological effects, etc...) to be on the order of several cents per kW-hr. And those cost estimates do not even include the greenhouse effect issue.

    I have some additional philosophical remarks concerning the article, and my above comment.

    In the comment above I discussed "external costs" of energy options. I also stated, that given the external (environmental) costs of conventional coal, both nuclear and IGCC coal are superior (i.e., lower "overall" cost) options, despite their somewhat higher economic cost. With respect to public policy, I favor pollution taxes, based on scientific estimates of the external (i.e., social, environmental) impacts of each emitted ton of the pollutant in question.

    The effect of such a policy is that the economic price (i.e., the price charged) for a given energy option would actually represent the true, overall cost of that energy option. One these "correct" prices are set, we can rely on the free market to make the energy choices, the result being a convergence on the minimum overall cost approach. The market would choose to make pollution reductions then they are "worth it" and would not choose reduction techniques when they are not. This approach results in a perfect balance of economic and environmental considerations.

    Mr. Weissman discussed the possibility of jobs moving off-shore as a result of higher energy prices. I expect this argument will often be used in opposition to any policies that weigh environmental costs, such as the one outlined above.

    For example, would policies like the one I described above cause utilities to shift to (or at least cling to) using gas instead of coal for a much longer time (and to a much greater extent) than they otherwise would? Yup. Would it result in the price of gas going higher (before the "equilibrium price required to drive a shift to coal is reached) that it otherwise would? Yup. Would this result in higher gas costs for other, competing applications for gas, such as home heating? Yup. (My guess is that the price of gas would rise until it reaches the point where nuclear and/or IGCC are cheaper than gas plants, as opposed to merely rising until conventional coal is competative (i.e., about 1 cent/kW-hr equivalent higher)).

    My answer to all these issues is simply this. "I'm afraid that that's what the energy actually costs." None of the above issues constitutes a reason to simply deny the external costs of various energy options (e.g., conventional coal). That is, to simply pretend they do not exist. These costs do exist, and no logic can justify not having them be reflected in the energy price. I also have faith in the general market concept, and generally believe that the market (undistorted by subsidies) finds the lowest overall cost solutions. For example, the market response to an overall (external) cost policy will yield the lowest overall societal cost even though it will result in higher gas costs for non-power generation applications (e.g. home heating), as well as for power plants.

    Concerning job loss issues, the issue is whether or not we should subsidize energy costs (keeping them artificially low) in order to keep industry (espeically energy-intensive industry) in this country. I'm not giving an opinion on this; stating if it is right or wrong. I'm just saying that it is a decision we'll have to make. Are we willing to subsidize energy costs, thus paying for some fraction of the energy cost through our taxes, as opposed to through rates, in order to keep these jobs. Another option is subsidizing industrial rates through increased residential rates (it's done all the time).

    Whatever we decide, we should at least be clear on what we are doing, and call a subsidy a subsidy. We should just admit, we are subsidizing energy costs to keep various industries in this country. Anything that reduced the price charged for power, versus is true, overall cost, is a subsidy. Thus, subsidizing any power source (through govt. largesse, tax breaks, loan guarantees, royalty breaks, etc...) is a subsidy. Lax pollution standards are a subsidy. More generally, not including the external costs of power generation is a subsidy (the effective subsidy rising in proportion to the pollution effects of the source in question). Such policies all reduce the price of power, but we (society) pay for it elsewhere, either through our taxes, through our medical bills, or (in some cases) with our very lives.

    Getting back to the specifics, many (including the author) would recommend a return to conventional coal, as opposed to using gas. This would be done to "help the US economy", and prevent those jobs from moving overseas. True, but it will also result in higher public health and environmental costs, costs which are not weighed by our current economic system (a system that features lax requirements on coal pollution, and no economic penalties for pollution).

    I'm not saying I prefer to continue using gas for baseload (I strongly state otherwise in my first comment). I do, however, strongly prefer using nuclear (or perhaps IGCC coal) over using

    I'm not saying I prefer to continue using gas for baseload (I strongly state otherwise in my first comment). I do, however, strongly prefer using nuclear (or perhaps IGCC coal) over using conventional coal, despite the (~1 cent/kW-hr) cost increase. I'm also saying that if insisting on these somewhat more expensive options results in somewhat higher gas usage and gas costs (before the power industry is finally goaded into switching over from gas), so be it.

    Re nuclear: for what it's worth, my personal view is that one of the decisions we're likely to most regret over time is the decision to move away from nuclear in the early '70's.

    And I believe it is critical that we begin reviving the nuclear option as rapidly as possibly.

    The reason I put even more emphasis on coal, however, is that I see our most urgent priority as being to focus on steps that can reduce the shortfall in our energy supply in the relatively near term.

    As important as I personally believe it is to start expanding our nuclear fleet, using next generation plant design, realistically it is likely to be many, many years before the first new commercial reactor goes into service and even longer before a return to nuclear is widely-enough accepted to significantly affect our overall generation mix.

    We face huge supply deficits, starting potentiallly right now.

    At least in my judgment, therefore, its critical that we discipline ourselves by starting every policy discussion of what we should due next by focusing on the steps that will have the greatest impact in the relatively near term.

    This clearly should include energy efficiency; there are huge energy (and cost) savings that can be achieved, for example, by improving efficiency of energy utilization in existing commercial office buildings and retail shopping malls (perhaps the best source of "low hanging fruit" from an energy efficiency standpoint).

    It also certainly should include a role for renewables.

    Its hard to see how we can possibly close the gap over the next 5 to 7 years, however, without it also including a major role for coal.

    Gassification also may be particularly important, given the $ 100 billion + we've sunk in new gas-fired generating equipment over the past 4 years, expecting expanded fuel supplies we now know will not be forthcoming.

    This debate will go on for some time--more Nuclear or Clean Coal, Renewables and the topic -Natural Gas. Storage of NG is mentioned, but not the storing of Energy from the baseloaded plants that must be turned down at night and during periods of low use.

    Bulk Energy Storage can be achieved with Pumped Hydro or Compressing Air during low utilizatioin periods and storing this in underground caverns(resevoirs) and released to NG fired Expanders during demand periods . ( only 2.5% of the US installed generation base is Energy Storage primarily in the form of Puimped Hydro) This technology(CAES) readily available , would best utilize efficient generating plant, keep older polluting coal plants off line, reduce natural consumption, as well as reduce emissions. More than that, the low capacity factor on Wind Generation could be improved, storing Energy when the wind blows at the wrong time, or blows too much( excess energy) when other baseload plant meet the demand efficiently.

    Energy Storage systems , provide load management, regulation-frequency and voltage, and ancillary services of VAR generation, spinning reserve etc.At the Substation level Flo-Batteries, as now being demonstrated by PacifiCorp and VRB Power Systems, is one option and Small CAES systems using pipestorage of air could also be employed. At the distributed level batteries have always fulfilled the need, however hispeed flywheels are now being introduced using less space and suitable for hi-cycle use vs batteries, and can be "boxed" in multiples of 10 to provide One MW output-such units are also mobile.

    Bulk Energy Storage from 100's to 1000's of MW to smaller systems15MW to 100kw can help the Generation Industry become more efficient, increase reliabilty , reduce NG consumption and reduce emissions as well. Storage caverns, resevoirs as in the case of NG can be developed over a wide section of the continental US and Canada. Such geological sites with Salt domes, hard rock or saline aquifers or depleted gas wells are well distributed for the Bulk Storage of Electricity in the form of compressed air, and should not be a deterent to the technology and the benefits that will accrue to the Power Generation and Transmission Industry.

    Good, thought-provoking article ... hopefully it can be action-provoking ...

    Expanding upon James Hopf's first comments on 11.25.03 regarding the call for more strategic gas usage in local, more efficient cogeneration applications, the notion that natural gas has become the “crack cocaine” of the power industry' rings more true each day.

    Consider the facts that (a) 40-60% of gas used by properly "right-sized" Combined Heat & Power systems is already consumed at industrial and commercial sites for heat production only, and (b) readily transportable natural gas is obviously ideal for load-centered applications (especially in comparison to the remote usage tendencies of various solid fuels ideal for central power stations), and (c) engineering integrity verifies that sub-5,500 btu/kW-hr, HHV heat rates achievable by custom CHP designs should be promoted over the good, but inferior, 6,500-7,500 btu/kW-hr, HHV achieved by modern CCGT systems.

    Indeed, these 3 foundations substantiate the tragedy that our society continues to get blindsided by an irresponsible power industry that refuses to place business and commercial needs over the relentless pursuit to site increasingly larger and less efficient CCGT systems as close as possible to "trading hubs" (a.k.a. Ivory Towers) with no consideration for what our country really needs.

    Don't let the utility and IPP community keep getting away with the Economy-of-Scale alibi, either: existing incentives, combined with decreasing first costs and increasing efficiencies (value) offered by global CHP major equipment leaders like GE/Jenbacher, make for even sub 5 MW systems that are being installed for total costs in the $1,000 per kW range.

    In closing, don't let the promoters of emerging (and undoubtedly important) technologies like fuel cells and microturbines get away without rebuke as they play their role in propagating myths and confusion about fuel optimization: despite decades of global proof about the proven merits

    The point is that, as a whole, the energy sector is letting America down. Basic engineering philosophy defines applied sciences in relation to how those applications serve society. If lack of research about commercially available and proven technologies, short-term thinking, apathetic plant siting, and an unwillingness to roll up our collective sleeves and help provide energy in forms and locations that are truly useful are any indication, our philosophies are more void than valid.

    Mr. Weissman's diligent work should not be in vain. Regardless of how abundant we might think our resources are (and I am as grateful as anyone for what this great country has been blessed with), there is never a good excuse for poor stewardship.

    Andrew Weissman is one of the few analysts of this sector that consistently cuts through the wishful thinking, political rhetoric and distorted perspectives of special interest advocates to offer a clearer view of our energy future. It is notable that there has been to substantial rebuttal to Mr. Weissman's presentation.

    I am not a prolific writer, but I have been an analyst of energy and regulatory policy issues for more than 30 years. I have been expressing similar views of our national energy future for at least the past five years, but few have listened. The natural gas "bubble" is long gone, but as a society we are still responding to natural gas and overall energy supply issues as though it still exists. I strongly encourage Mr. Weissman to continue his efforts to "puncture" these myths.

    Furthermore, as a participant in the analytical efforts that supported the "Project Independence" endearor of the mid-1970's, I find the shortness of our societal memory appalling. We learned in the 1970's that natural gas was not well used in large stationary sources (e.g., power plants), but since the early 1990's it has been neither policially nor economically expedient talk about building anything other than gas-fired generators (and renewables). A high national priority should be to back as much natural gas as possible out of electric generation.
