What fixed vs. flexible retail power rates in Texas tell us about wind power in the ERCOT market

January 13, 2009

Michael Giberson

Electric power consumers in (the ERCOT portion of) Texas have many choices when it comes to the electric power retailer they wish to enroll with, and typically each retailer offers a handful of different plans.  Historically speaking, this is a crazy cornucopia of consumer choice not seen anywhere else in the world. Or, seen from another point of view, a lot of data for economists interested in retail electric power not available anywhere else. This post dissects a few bits of that data and offers a preliminary conclusion.

One choice available to many Texas power consumers, but rare elsewhere, is between rates that are variable from month-to-month and rates that are fixed for a longer term.  Typical terms for fixed rate offers are six months and one year, but terms as long as five years are offered.

The primary difference between a variable rate and a fixed rate is whether the customer or the retailer is exposed to the risk of adverse price movements.  A little simple economics leads one to expect that if the retailer is to take on the risk of adverse price movements, the customer will have to pay the retailer to take on the risk. So we’d expect that fixed rate contracts would tend to be higher than variable rate contracts.

And that is just what we see in the offers listed at www.powertochoose.com, the State’s online list (just comparing average offered fixed rate deals to average offered variable rate deals). For example, in the Houston area the average rate for fixed price offers was 14.04 cents/kwh and the average rate for variable price offers was 13.60.  In Dallas, fixed price offers averaged 13.35 cents/kwh and variable price offers averaged 13.03.

But elsewhere in north Texas, specifically the AEP North Texas distribution service territory, the average rate for fixed price offers was 12.7 cents/kwh and the average rate for variable prices offers was 12.8 cents/kwh. So, apparently in parts of north Texas, electric retailers in effect are willing to pay consumers a little bit in exchange for taking on price risk.

Crazy, right?

Well, not exactly.  A fixed rate offer transfers the exposure to both adverse and beneficial price movements.  If a retailer expects prices to fall (relative to the current market expectations), then it would want to encourage customers to lock in at current rates; if the risk of a price movement down is larger than the risk of a price movement up, and retailers are less risk-averse than individual consumers, then retailers would be willing to pay consumers to take on the risk.

And why might retailers in certain parts of north Texas expect prices to fall? Might it be access to large quantities of wind power that sometimes can’t reach Dallas or Houston due to transmission limits – sometimes such large amounts of wind that prices in the ERCOT west region go negative?

I think so.

Admittedly, simple averages of offered fixed and variable rates provide only the coarsest of indicators of what is going on. Maybe more sophisticated analysis makes the anomaly disappear. But at first glance, it looks like another market indicator of the temporary excess supply of subsidized wind power in west Texas.

Cass Sunstein, OIRA, and nudging

January 13, 2009

Lynne Kiesling

On Thursday President-elect Obama named law professor Cass Sunstein to head the Office of Information and Regulatory Affairs, an executive-branch office with the mission of analyzing and coordinating federal regulation. Most recently, Sunstein is known for his work with Richard Thaler on “choice architecture” and behavioral public policy, including their book Nudge.

Others have already opined about Sunstein’s appointment, including Saturday’s editorial from the Wall Street Journal and this Forbes column from Glenn Reynolds. Matt Welch helpfully aggregates several commentaries on Sunstein’s appointment in his Reason post. The consensus seems to be that Sunstein’s approach to regulation is not premised upon bureaucratic imposition and control, that his primary focus is to improve markets and competition, not to stifle them through government regulation, and that much of this is likely to be irrelevant because OIRA is a politically impotent office, so his efforts will have little effect.

Most observers will be watching to see what form Sunstein’s focus on “choice architecture” and behavioral public policy will take when and if it gets implemented. The premise of this behavioral approach to what I (and Elinor Ostrom) would call institutional design is Sunstein’s and Thaler’s so-called “libertarian paternalism”. Sunstein and Thaler draw their normative policy implications from behavioral economics research that suggests that real-world decision-making does not always result in individuals making the decisions that theoretical models suggest would be optimal, or rational. In his review of Nudge, Will Wilkinson cites some examples:

If a cafeteria puts its key lime pie a bit out of the way, fewer people will succumb to delicious temptation. If employees are not required to fill out confusing paperwork to enroll in a savings plan, more of them will enroll.

One area where this behavioral issue comes up in electricity instutional design is the design of fixed-price default service contracts, and whether the default contract should be opt-in or opt-out. Those who argue it should be opt-in base their argument on consumer inertia and status quo bias — if the heretofore-regulated incumbent is the default service provider and the default contract is opt-out, innate consumer inertia would predispose them to stay on the default contract, even if competing suppliers could now enter the market and offer services that would likely be appealing to those customers. Thus by reinforcing existing inertia and status quo bias, the opt-out default contract reduces competitive entry into new retail electricity markets, and stifles retail competition. This opt-in/opt-out design dimension is relevant for health care plans, retirement plans, any sort of contractual choice situation with a status quo option.

In some ways this approach is a refreshing change from regulation that is informed by traditional, neoclassical economic modeling of individual choice, which is devoid of any formal attention to the real cognitive constraints that individuals face daily when bombarded with information and making choices in the face of budget constraints, information constraints, and (to use the Austrian phrase for it) radical ignorance — some of what individuals need to know to make the decisions that they would in our formal theoretical models is simply unknowable. Note here that the ideas I am using originate in the work of Herb Simon on bounded rationality and the use of heuristics in individual decision-making, and of Michael Polanyi on tacit knowledge and the extent to which we know stuff that we don’t know we know, and our brains subconsciously make choices constantly, which enables us to function in our information-rich environment without being overwhelmed. This behavioral approach to institutional design takes into account two important aspects of reality:

1. Individuals do face cognitive limitations on their decision-making, and have evolved adaptation mechanisms to deal with them.

2. To live together in civil society, we do have to engage in collective action, which requires institutional design.

In other words, take people as they really are, and when we have to engage in collective action, design institutions that take into account those cognitive realities. Yes. But here’s where my skepticism about the Sunstein-Thaler libertarian paternalism kicks in. Much of what is important in public policy is shaping incentives and future behavior. If we take Simon and Polanyi, and Hayek, seriously, then it’s crucial to acknowledge that a lot of what shapes incentives and future behavior is not just unknown — it’s unknowable. We don’t know our own preferences completely — we discover them through market processes, and through the process of making decisions. We don’t know what future choice sets will look like, let alone what our preferences over those choices will be. These things are simply unknowable, and therefore designing institutions to affect those unknowable incentives and outcomes is almost always likely to end up in failure. This approach to choice architecture cannot overcome the knowledge problem. So I think the best that we can hope for from such a so-called “libertarian paternalism” approach to regulation is small, local changes in design parameters that are well-known and relatively non-controversial.

Another aspect of the challenge to this approach to institutional design is indeed the elitist-paternalist critique: how will the regulator know in every situation that Choice B actually would make the individual better off than Choice A? What makes you think that you know what is better for me than I do? Seriously? Again, the unknowability of preferences until presented with a real choice situation, even to the person possessing them, makes it highly unlikely that any third party can know that one outcome would be better for a person than another outcome. This is old territory that has been covered elsewhere, including this April post from Will Wilkinson, so I will stop here, except for one observation: just because we face cognitive limitations to decision-making, that does not necessarily mean that the ultimate outcomes of decision-making are inefficient, or irrational, or “anomalies”, to use one of Thaler’s favorite linguistic tropes. Again, taking Simon and Polanyi and Hayek seriously, we devise conscious and subconscious adaptations to these cognitive realities, we use technology to help us filter and to make decisions that better reflect our preferences as we perceive them. Who are you to say that the outcome of that process is irrational or inferior?

Another question to ask when thinking about the process of institutional design and behavioral economics: why would these “Nudge” rules be any less prone to political manipulation, lobbying, and rent-seeking than more traditional top-down institutional design? The electricity default contract is an example; the traditional “consumer advocate” community generally uses its political and advocacy power to argue that opt-in default would expose consumers to too much unwanted price volatility and too much effort to avoid that price volatility, so the default should be everyone going on a fixed-price contract unless they want something else. “Nudge”-based institutions are still institutions of collective action, and thus are still going to have the same incentives for manipulation, lobbying, and rent seeking.

Finally, while I do think that the process of institutional design, including regulatory institutional design, can benefit from thinking about these choice architecture questions, I do think the “libertarian paternalism” nomenclature does a disservice to the language. “Nudge” applied to regulatory policy is not strictly libertarian, because regulation is still ultimately grounded in coercion. The “choice architecture” language does a much better job of communicating what this idea is about — incorporating behavioral and cognitive reality into institutional design. At least the “Nudge” approach to regulatory policy is more respectful of individual autonomy and choice than the likely bureaucratic alternatives.

In devising OIRA policy I’d like to hear Sunstein invoke another of his former Chicago colleagues, Ronald Coase, and state that in promoting and facilitating open, transparent markets, the most important role of economic regulatory policy is to reduce the transaction costs that prevent private parties from engaging in mutually-beneficial exchange. That means using OIRA to evaluate the entry barriers and other transaction costs that federal regulation can create. OIRA does cover other areas of regulatory policy where the ideas of transaction costs are not as strictly relevant, but thinking in terms of reciprocal benefit, reducing transaction costs, and the alignment of, for example, environmental and economic incentives through the reduction of transaction costs and better-defined property rights transcends economic regulation.

Russia and Ukraine natural gas disputes illustrate the bilateral monopoly problem

January 12, 2009

Michael Giberson

At the Streetwise Professor, Craig Pirrong writes that the periodic interruptions in natural gas flows from Russia across Ukraine present a “classic bilateral monopoly situation.”

Bottom line–there are no saints involved in this episode.  There is a classic bilateral monopoly situation.  Each side is using its leverage to try to extract as much from the other as possible.  There is a substantial rent to be had, and Ukraine and Russia/Gazprom are using every lever they can to get the lion’s share of that rent.

More:

In essence, Ukraine is using the market power inherent in its control of the pipeline between Russia and Europe in exactly the same way Russia/Gazprom has used the market power inherent in its (government granted) monopoly over the pipeline between Turkmenistan and Europe.  And which it also uses, by the way, to stifle competition from other Russian producers of gas.

His prognosis:

This conflict is inherent in the dysfunctional market structure upstream and midstream.  State mandated monopolies over transportation in Russia and Ukraine, with no system of open access and common carriage, distort markets.  When these monopolies are back to back, rent seeking battles are inevitable.

Absent some regime of open access, or common carriage at regulated rates, the distortions in the Eurasian gas market will persist.  The second best alternative is to create additional pipeline routes connecting other sources of gas (Turkmenistan, Kazakhstan) with consumers downstream.  Importantly, these additional routes must not be in control of the incumbents–notably Gazprom–so Nord Stream and Blue Stream South Stream don’t help.  An additional, non-Gazprom pipeline would create additional competition (though far from anything resembling perfect competition) both for the gas, and for the transport of gas.

This is not likely to happen anytime soon, given the difficult economics of Nabucco, the dynamics of the new Great Game in Central Asia (and Russia’s strong strategic hand in that game, and its ruthlessness in playing it), and the pathetic dithering of the Europeans.  Which means that the gas wars will remain as regular a New Years event as the Rose Bowl and hangovers.

Low entry barriers in electric car market

January 12, 2009

Lynne Kiesling

Very interesting story in today’s Wall Street Journal about BYD, a Chinese firm manufacturing electric vehicles. One of the most interesting points in this article: despite the global economic downturn, BYD is increasing its operations, first in China and then planned for US and Europe, because entry barriers are lower in the electric vehicle market than in the internal combustion vehicle market.

Mr. Wang’s strategy: capitalizing on the electric car’s low barriers to entry. Few products are as complex to develop and produce as gasoline-powered automobiles, which are assembled with thousands of precisely engineered parts. But electric cars use only basic motors and gearboxes, and have relatively few parts. Aside from perfecting the battery itself, they’re far easier and cheaper to build — and that makes for a level playing field.

“It’s almost hopeless for a latecomer like us to compete with GM and other established auto makers with a century of experience in gasoline engines,” said Mr. Wang in an interview, pacing and juggling calls in BYD’s headquarters on the outskirts of Shenzhen. “With electric vehicles, we’re all at the same starting line.”

BYD has other factors working to their advantage — low labor costs, innovations in battery technology — but the demand for electric vehicles is still not particularly large or particularly intense. The article also discusses the constraint that battery technology presents, and some of the innovations that BYD and others are doing to relax those constraints.

My predictable comment on the NFL playoffs

January 11, 2009

Lynne Kiesling

I have one thing to say today: GO STEELERS! I will be sportin’ my black and gold swag at home today, and watching the game.

I like watching the Steelers, but I have to admit that the thing I really like most about watching the Steelers is seeing the cityscape photography of Pittsburgh during home games. Makes me a wee bit homesick … even though I haven’t lived there since 1979!

Culinary notes: foods that are good for you, including … duck fat?

January 9, 2009

Lynne Kiesling

A couple of nifty food notes have crossed my path today. First, an incredibly handy list of places to find duck fat french fries around the US, including the fabulous Hot Doug’s in Roscoe Village in Chicago. Yummmmm, encased meats! Interestingly, the hat tip for this article goes to John Hodgman’s Twitter feed. I love when Twitter is substantive!

On a related note, at New Year’s Eve dinner one of my friends claimed that duck fat has similar health benefits to olive oil and other unsaturated fats. I was skeptical but hopeful, as I am a huge fan of duck. Turns out she’s right, and I’ve even found a 1991 New York Times article on the French (quelle surprise!) research substantiating the claim:

In a paper presented to a convention of duck and goose producers in France last spring, Dr. Renaud suggested that goose and duck fat may improve cardiovascular health. Only clinical studies can determine the benefits of the fat from web-footed birds, but chemists agree with Dr. Renaud, who said in a recent telephone interview, “Goose and duck fat is closer in chemical composition to olive oil than it is to butter or lard.”

A more recent New York Times article, from June 2008, lists some of the foods that are relatively easily accessible that you should be eating but probably aren’t. These include beets (YUM), swiss chard (yum), frozen blueberries (YUM!), canned pumpkin (YUM), and sardines (yuck). The article also helpfully lists ways to prepare these foods. After first reading this article over the summer I bought a tin of sardines, and they still sit in my pantry, awaiting the appearance of my steely nerve to get me to try to choke them down. I think I’ll follow the article’s advice and mulch them into a purée with mustard, onions, and lots of pepper. My idea was to grill them, but it got to be winter before I steeled my nerves to do so.

My benchmark oil price is better than yours

January 9, 2009

Michael Giberson

The WSJ’s Environmental Capital blog notes that the price for “WTI”, which is to say the price for West Texas Intermediate grade of crude oil, a commonly used benchmark for quoting crude oil prices, has been drifting out of the usual relationships with other commonly used benchmarks, like Brent crude. (Here is Wikipedia on WTI and Brent.)

The post cites opposing views from FT’s Alphaville blog and Platt’s The Barrel. At Alphaville, the changes indicate that WTI is losing touch with reality:

Essentially that means once Cushing storage nears capacity WTI will become increasingly depressed versus other crude grades and therefore disconnected from real oil supply/demand fundamentals. As a result it will no longer be a good indicator of US crude prices.

While at The Barrel, the WTI price movements are reflecting reality:

So it’s WTI that’s reflecting what is going on in the world: the collapse in demand, oversupply and a resulting enormous contango that is encouraging storage. On this one, WTI is ahead of the curve, not behind.

Why the difference?

Maybe where you sit affects what you see.  Should I say more clearly that the U.K.-based Alphaville blog favors the local Brent benchmark, while the U.S.-based The Barrel thinks that WTI is all right.

My view, from here in Lubbock: West Texas Intermediate is A-OK.

What model for the financial system breakdown? Falling dominoes? Cascading outages?

January 9, 2009

Michael Giberson

Simon Johnson reviews and provides a summary of a paper by Daron Acemoglu on the current financial crisis.  Johnson summarizes one of Acemoglu’s points as follows:

The seeds of the crisis were sown in the Great Moderation (the low inflation, relatively stable last 20 years or so).  Everyone who patted themselves or others on the back during that time was really missing the point (p.3).  The same interconnections that reduced the effects of small shocks created vulnerability to massive system-wide domino effects.  No one saw this clearly.

This kind of model – in which greater resistance to small shocks can create vulnerability to large system-wide effects – has been employed to understand the relationship between reliability in electric power systems.  It seems to be the case that at least many of the things that a local electric transmission system does to improve reliability work to push the larger system of interconnected local systems to a state in which it becomes more vulnerable to severe reliability failures – cascading blackouts.  There seems to be a kind of frontier, given the current state of the transmission system, where we can choose to have more frequent small blackouts and a very low risk of a huge blackout, or we can choose to have infrequent small blackouts with a slightly higher risk of a huge blackout.  (See, for example, work on cascading blackouts by Ian Dobson, Benjamin Carreras, David Newman and others, collected here, especially this paper.)

Of course, not every system shows this kind of interrelationship – making individual automobiles more reliable doesn’t increase the probability of a widespread automotive system failure, making telecom components more reliable doesn’t increase the probability of a cascading outage of phone services – and it is an open question whether this kind of model can be well employed to describe risks in the financial system.

To be fair, it is also an open question whether more conventional kinds of economic models can be well employed to describe the recent turns in the financial system.

Aviation biofuels tested

January 8, 2009

Michael Giberson

The Houston Chronicle, among others, report on a Continental Airlines test flight relying in part on biofuels.

On Wednesday, a Continental Airlines Boeing 737-800 became the first U.S. commercial jet to fly on a mix of conventional jet fuel and biofuels….

“The airplane performed perfectly,” test pilot Rich Jankowski said. “There were no problems. It was textbook.”

The plane burned 3,600 pounds of a 50-50 jet fuel-biofuel mix in one engine and roughly 3,700 pounds of traditional fuel in the other, meaning the test batch was somewhat more efficient, he said….

The biofuel blend is noteworthy because it is “drop-in” fuel, noted Larry Kellner, Continental’s chairman and chief executive. That means neither the aircraft nor the engine need to be modified to fly, he said.

The biofuel blend included components derived from algae and jatropha plants. Both are sustainable, second-generation sources that don’t have an effect on food crops or water resources, according to Continental.

The algae oil was provided by Sapphire Energy, and the jatropha oil was provided by Terasol Energy. Other partners with Continental on the project were Boeing, CFM International, a joint company of General Electric and Snecma, and refining technology developer UOP, a Honeywell company.

Sustainable biofuels for aviation are a real near-term option, Jennifer Holmgren, general manager of UOP Renewable Energy and Chemicals, said Wednesday.

“We believe production levels could reach hundreds of millions of gallons per year by 2012,” Holmgren said.

Last week Air New Zealand conducted a similar test, also using a blend of conventional jet fuel and a jatropha-based product. These tests and others are part of a concerted industry effort to collect data on biofuel performance.  In the Continental Airlines test, only about 2.5 percent of the biofuel was from algae and the rest was from jatropha.

The United States produces nearly 18.6 billion gallons of aviation fuel annually (approximately 600 million barrels), so a mere added “hundreds of millions of gallons” annually would be a just a few percentage points. Still, diversifying sources of fuel supply could be useful, and of course environmental benefits are the intended target of the efforts.

Aviation fuel proponents are keen to avoid the food-vs.-fuel backlash that has hit ethanol. One reason for the attraction to jatropha is that is will grow on what would be low-quality or non-arable lands.  But of course if it will grow on low-quality lands, it will likely do well in high-quality lands, too. Part of Terasol Energy’s role in providing the jatropha oil was to certify that the source jatropha was grown on land that was not mechanically irrigated, and that the land was neither forest land nor virgin grassland within the previous two decades.

Aviation biofuels do have their critics, and WIRED’s Autopia blog conveys the concerns of Jeff Gazzard of the Aviation Environment Federation:

“For us, the jury is still well and truly out as to whether either synthetic or biofuels are yet capable of being either entirely fail-safe for aviation use or environmentally sustainable in the longer term,” Gazzard writes in his report, Bio-Fueled or Bio-Fooled.

… Gazzard is underwhelmed by the high-profile alt-fuel tests we’ve seen to far. Like others, he dismisses as a publicity stunt Virgin’s much-ballyhooed test flight of a Boeing 747 that flew from London to Amsterdam with one of its four fuel tanks carrying a 20 percent mix of biofuel. The plane, which used a mixture of coconut and babassu oils, would have needed some 3 million coconuts had it made the flight entirely on biofuel, he says.

… Gazzard argues the aviation industry and governments are more interested in appeasing critics than finding alternatives to oil.

[Link in source.] No doubt it is true that both companies and governments are interested in appeasing critics, but I certainly do believe that airlines would be happy to find an alternative to petroleum-based fuels, at least if it were not much more costly that petroleum while at the same time seen as better for the environment.
