CERA Week and smart grid “thought leadership”

March 14, 2011

Lynne Kiesling

As you energy gurus know, CERA is one of the leading consulting firms in the energy space, and hosts an increasingly popular event called CERA Week — rather like the Davos of the energy world! In support of the event this past week, CERA has splashed out for two large advertising sections in the Wall Street Journal. Wednesday’s special advertising section (pdf) includes an article from Larry Makovich entitled “What Really to Expect from a Smarter Power Grid.” I recommend reading his high-level analysis, although I find his logic and his thinking limited in some important respects.

He starts by identifying the promise of smart grid, but cautions against being too optimistic:

Many see the smart grid as a disruptive technology ready to transform the power sector. According to this view, the smart grid will unleash pent up efficiency, integrate distributed renewable generation, enable electric vehicles, reduce greenhouse gas emissions and, in the process, lower consumer power bills. But this vision in its entirety is too good to be true.

Both Mike and I fit into that “many” who see smart grid as a disruptive technology that can enable private individuals to create value, but I think we each have our doubts about how many regulatory and cultural barriers will limit that value creation and will make it more incremental. Let’s see if Makovich concurs …

He then goes on to point out that the grid isn’t as “dumb” as it might appear, and as evidence for this claim he offers the fact that “integrated control centers … employ real time data and sophisticated software”. While this claim, and his subsequent claim of the use of virtualization to simulate the grid, do indicate evolution and the use of digital technology, much of what he’s describing there is quite limited to transmission and high-level distribution. Once you get below that in the network, his argument fails. Control centers may be technologically up-to-date, but they see mostly aggregates. Some of the most crucial elements in the network for reliability and for end-user value creation are below the control centers — substations, transformers, and end users are technological black holes. Those are precisely the areas where smart grid technologies can be beneficially disruptive, but Makovich’s glossing over of where in the network the intelligence already exists allows him to dismiss the potential benefits of distribution automation and intelligent end-use technologies.

And that’s where Makovich goes next:

At the heart of the current narrative about the smart grid is a conviction that power customers want to be able to manage their consumption in response to different power prices at different times of the day. The idea is that consumers could adjust their usage to take advantage of lower prices during periods of slack power demand. But it is not very likely that varying pricing over the day—what is called “dynamic power pricing”—will be the hoped for killer app of the smart grid.

Makovich is creating and taking down a shaky straw man here, and omitting some of the most important reasons why smart grid technology could be beneficially disruptive but is not. Not even the most breathy enthusiasts for dynamic pricing (self included) would categorize it as having “killer app” potential — but what does have such potential is the set of possible end-use technologies for home energy management and digital home integration that reduce the transaction costs to consumers of choosing dynamic pricing while still enabling them to save money at an ambient comfort level they choose. Makovich spends almost half of his article on why dynamic pricing isn’t the be-all-end-all and why consumers don’t want it … without even mentioning one single word about such potentially game-changing customer-facing technologies! As we have seen repeatedly in several pilot demonstrations, customers are more enthusiastic about dynamic pricing when

  1. They get to choose it rather than having it foisted upon them by bureaucratic fiat
  2. It accompanies digital end-use technologies that consumers can use to respond to prices for them

Makovich addresses neither of these topics in his article, which is a substantial omission that undermines his argument considerably.

Finally, he also fails to discuss one of the primary drivers of the slow, incremental adoption of smart grid technologies: regulation and regulatory incentives. He comes close when he notes that “… smart grid technologies will likely reinforce the traditional industry structure …” because of focusing investments in the power supply portion of the network. But he leaves the elephant in the room, and doesn’t discuss how regulation makes regulators and firms risk-averse in the face of new technologies, even when said new technologies would improve our ability to provide desired reliability along with a host of other value propositions that their top-down control culture and mindset cannot imagine. He doesn’t discuss how regulation defines market boundaries and stifles the discovery of other value propositions beyond plain-vanilla electricity service. In fact, he’s missing the role that regulation plays in deliberately preventing smart grid technologies from being beneficially disruptive.

A reporter with an in-home energy monitor and a blog

November 5, 2010

Michael Giberson

After months of paying a ‘smart meter’ surcharge on his power bill, Houston Chronicle energy reporter Tom Fowler finally had a smart meter installed by CenterPoint Energy several weeks back and more recently an in-home energy monitor. He’s blogging the revolution:

When the word gets out about toasters, they may be relegated to museums and history books. One wonders what other changes this slow motion revolution may bring.

Building a “passive house”

October 2, 2010

Michael Giberson

Many critics of smart grid-related ideas for saving energy object that consumers won’t want to sit around watching energy prices, flipping light switches and delaying the dishwasher when prices spike now and again to save a few bucks. Of course the critics are right on this point. The best smart grid energy saving ideas are mostly in the realm of “fix it and forget it” devices. You set the dial and let the device do the work.

Perhaps the ultimate “fix it and forget it” device for home energy saving is a passive house – a house that is designed and built to require minimal amounts of energy. This isn’t a smart grid kind of thing – these designs are so smart that they can be dumb; they don’t need to know the price of electricity.

Or rather, because a passive home design requires additional upfront effort and expense, the smarts need to be exercised mightily up front. As discussed in an article in the New York Times describing a passive house being built in suburban Boston central Vermont (edited, see comments), such homes are more expensive to design and build. After that, it is mostly “fix it and forget it.”

What the Maryland PSC’s rejection of BG&E’s smart grid proposal reveals about regulation

June 28, 2010

Lynne Kiesling

Last week the Maryland Public Service Commission rejected Baltimore Gas & Electric’s proposed project to install over 2 million digital electric or gas meters, change the retail electricity rate structure to incorporate time-of-use pricing and peak-time rebates, and recover the meter capital costs through a surcharge on residential retail bills. BG&E’s ambitious and thoughtful project had undergone extensive pilot project testing and had generated economic and physical results similar to those seen in other such projects (customer savings, reduction in peak energy use and in peak strain on system infrastructure, reduction in peak wholesale prices due to the transmission of retail price signals). Their recommended technology and rate designs are not unusual relative to evolving practice in other states (although they are much, much less than I personally would like to see). Despite those promising results, the Maryland PSC rejected BG&E’s business case for structuring their cost recovery from the project as they did.

Although I am pretty familiar with the BG&E pilot, I am not sufficiently informed or expert in rate case matters to have an intelligent opinion on whether the PSC took the correct position. Their position, though, reveals some of the most important and pressing reasons why traditional economic regulation is incompatible with economic dynamism, with technological change, with innovation, and ultimately incompatible with widespread consumer well-being.

1. Traditional economic regulation is based on cost recovery, not on expected value creation, and therefore does a poor job of “standing in for the market” as it is (incorrectly) supposed to do in theory. Whether it’s enshrined in the legislation giving the regulatory agency its mission or in the deeply-embedded Populist culture and history of regulation, traditional regulatory procedures focus regulators and the regulated on providing a narrowly-defined, generic, highly reliable service at the lowest possible long-term cost. As long as you’re in a static environment, the static model from which this theory and culture emanate will do a decent job of providing that generic service. That’s the context in which regulators have developed a norm and a culture of ignoring value creation — focusing narrowly on the provision of generic electricity service and scoping your efforts accordingly fits with that static world. But regulatory models premised on cost recovery fail miserably in a more dynamic context, with pervasive economic and technological change and Schumpeterian creative destruction. That dynamism characterizes the economic and technological context of the early 21st century, and the reason that dynamism and creative destruction become so pervasive in human society is that they create value — value for consumers, variety for consumers, product differentiation for consumers, and value for the risk-taking and opportunity-seeking entrepreneurs who risk private capital to create that value.

If the regulatory institutions and the regulatory culture constrain the electricity value proposition to the provision of generic service to the exclusion of other product/service/pricing bundles, and if they constrain the business model to one of cost recovery instead of value creation, then the regulators will reject the types of projects that are most likely to create value for consumers and entrepreneurial producers. This rejection shows precisely why regulation cannot “stand in for markets”, because the most important function that market processes perform is the pathways for this new value creation. The static, price-determining, resource allocation function of markets is not the most important function of markets, and the formulators of static natural monopoly theory at the end of the 19th century got that wrong. Our current regulatory institutions are built on that incorrect, static natural monopoly theory.

2. Traditional economic regulation stipulates that the regulatory agency controls price determination on behalf of consumers, and regulators are loath to relinquish such power once they have had it for a century. This point is a political economy corollary to the first point. Legislation requires regulators to represent the interests of consumers, and they do so through administrative procedures to control both costs and prices, as well as controlling the profits that the regulated firms are allowed to earn. Control, control, control. Take, for example, this quote from the New York Times/Climatewire story linked above:

The Maryland commission took a fists-up stance toward its powers and prerogatives to rule on utility rates. “For one hundred years, since this Commission was created by the General Assembly in 1910, one of our primary functions has been to establish the rates that public service companies can charge their customers,” the commission said. Currently, it faces a growing trend by regulated companies to cover costs in advance through surcharges rather than subjecting costs to review after they have been incurred.

While it has approved such surcharges in some limited cases, it drew the line on BG&E’s current proposal, it said. “Surcharges guarantee dollar-for-dollar recovery of specific costs, diminish the Company’s incentive to control those costs,” and put those costs outside the commission’s reach, the commission said.

Ironically, Maryland is at least nominally a state that has retail competition and retail choice available for its residential consumers. If they were actually serious about competition and were willing to relinquish this control over prices and costs, then the regulation of prices and costs would occur through the decentralized market processes of firms making retail product/service bundle offerings to consumers, and consumers using their choice and autonomy to say NO. But if you are deeply steeped in regulatory culture, you do not believe that this decentralized process can work effectively for consumers, even though it does so in other markets and industries … even ones that have high infrastructure costs and are considered essential to daily life! You, therefore, believe that your power to control is a salutary intervention, even though the dynamism of economic and technological change are proving you wrong on a daily basis. So you make decisions that reinforce your power and control, believing them to be in the best interest of consumers while you deprive those same consumers of the opportunity to make their own autonomous choices.

3. Traditional economic regulation entrenches the political and economic power of easily identifiable, politically active special interests. Which leads us to the third lesson from this episode for the political economy of regulation. The legislative mandate for regulation, and the stated mission of every regulatory agency, is to control prices and allow the firm to recover costs for the provision of a generic service at a highly reliable level in a way that benefits all consumers. But in the time that I have been involved in regulation, and in debates over smart grid investments and policy, it is abundantly clear that Mancur Olson was correct, and that regulation actually represents the interests of easily identifiable, politically active interests, not the interests of consumers as a whole. On the consumer side, this means that decisions get made frequently based on the organized, coordinated political actions of so-called consumer advocates (who really represent low-income consumers, not all consumers) and groups like the AARP, who perceive their interests as being best served by the perpetuation of the traditional regulatory model — generic service provided at high reliability, controlling price through strict cost recovery.

Take, for example, this quote from the excellent Ahmad Faruqui in the New York Times/Climatewire story above:

While some state utility commissions are willing to back smart meter deployment, they are reluctant to approve new “dynamic” electricity rate plans that allow prices to rise during the day when power demand peaks and fall when demand is slack. Such real-time pricing plans are essential to prompt customers to shift energy usage to slack times and reduce overall consumption, he said.

“There is no doubt in my mind that without state commissions approving the business cases for advanced meters and the smart grid, this is not going anywhere. They control the dollars; they set the rates for the customers,” said Faruqui, an economist and principal with the Brattle Group. Faruqui testified before the Maryland commission in support of the BG&E plan and declined to comment on the commission’s decision in that case.

But he said that around the county, commissions are heeding warnings from state consumer advocates and retiree organizations about possible cost impacts on customers if electricity rates are linked to actual generation costs, hour by hour.

“Most of the state commissions are frozen in time. They are being subjected to these very, very pessimistic, worst-case arguments,” he said.

What’s missed in that calculation is the unseen, lost value that could be created for both these vulnerable groups and for other consumers by moving away from that model. When regulators are already predisposed, by legislation and by culture, to constrain the value proposition of the regulated firm and focus on a generic service and cost recovery, the political action of those who seem to visibly benefit from that constraint will find a big foothold. In that environment, the value proposition based on the idea of better service provision (such as, for example, bundling home health care monitoring services in with a “senior care” electric service contract for the AARP constituency) is going to fight an uphill battle. In open markets with low entry barriers, that type of service bundle would be able to compete, and would sink or swim, fail or profit according to the value it creates for consumers and the ability of the provider to control costs.

In brief, traditional economic regulation is incompatible with economic dynamism, with technological change, with innovation, and ultimately incompatible with widespread consumer well-being because of the enormous extent to which traditional economic regulation stifles experimentation. The really valuable function that market processes provide is this ability for consumers and producers to experiment. Traditional economic regulation is almost reflexively anti-experimentation, and that reflex is the source of lost value creation opportunities from smart grid technologies.

A historical example illustrates why I think these points are important. In the medieval period, China was one of the most forward-looking, open, technologically creative and vibrant societies in the world. Chinese inventions became the foundation of many important technologies, machines, and industries. Yet by 1600, China’s backwardness was obvious to all observers; China had closed herself off from knowledge, had become technologically stagnant. Western Europe and then the young United States surged ahead of China in technology, in economic productivity, in per-capita income, and in living standards for most of the population (China’s elite, of course, continued to enjoy luxury). Economic historians credit this stagnation (or, what Needham argues was “homeostasis”, not stagnation) and worsening of living standards for most of the Chinese population to conscious technocratic policy decisions in China to look inward (growing through population growth and increasing intensification of agriculture), to be backward-looking, and to make strong top-down rules based on status quo bias. Writ large, the dynamic driving the stultification of China had at its core many of the same policy drivers and incentives as we seen in play in electricity regulation in the 21st century.

Cogeneration vs. monopoly electric utility service, circa 1909

May 21, 2010

Michael Giberson

The Isolated Plant magazine published “A letter from a New York Correspondent,” in their August 1909 edition:

Mr. Editor:

From the viewpoint of one of the “common people,” the recent issues of your magazine have been striking fire with every telling blow…  The following incident is mentioned as a bit of local history.

Two downtown office buildings adjoining each other on the same side of the street, and carrying the same class of tenants, were not operating under sufficiently even costs.  One of them had its own electric power plant and the other used Edison service.  The man who operated his own plant even had a little power to spare and closed a two years’ contract with the other agent to supply the latter’s building with light at a rate considerably lower than the street service.  A contractor installed a 3 inch loricated conduit carrying three double braid conductors between the generator switchboard through the foundation wall to one side of a three-pole double-throw service switch previously installed.

This switch had been used to supply Edison break down service when the building operated its own plant.  The wiring was installed in full accord with the National Code as adopted by the N. Y. Board of Fire Underwriters, and a certificate of approval was received from the city department.  The contractor received a “violation,” however, from the Fire Underwriters, and any attempt to secure a committed statement from the latter board as to the code rule violated was futile.  This was evidently somewhat peculiar, the contractor had performed his work according to the rules of the board as publicly printed and circulated, yet a certificate of approval was withheld, and he could not receive his payment for the work.  The inspector was called on, he was non-committal … the Chief Inspector was non-commital … [The] Superintendent … quite abrubtly stated that his board would not approve the running of an electric power service through a party line; this ruling being the result of an agreement between his board and the N. Y. Edison Co.

Neither contractor nor agents could understand how any such mutual agreement could affect the fire risk….

The N. Y. Edison Co. also got busy after the contractor and threatened to send him to jail for “interfering with their meters,” which of course was not the case and the contractor was not molested; threat was also made to discontinue the [Edison Co.] service to the elevators, but it also passed over.

Both buildings secured independent insurance, the contractor got his money, and each agent fulfilled their two years’ agreement.

C. J. H.

At a time when cogeneration, smart grids, and decentralized energy resources are creating challenges around the fringe of standard regulated retail power service, it is interesting to see how the battled played out a century ago, when state regulation of monopoly regulated utilities was new and competition between central station power and the isolated plant was ongoing.

The Isolated Plant magazine has been digitized by Google Books.  See also the related post of a week ago, “The central station and the isolated plant.”

“The central station and the isolated plant”

May 14, 2010

Michael Giberson

H. S. Knowlton said, “In the establishment of many kinds of modern business the question of cheap power is one of fundamental importance, and in not a few cases the industrial manager finds it a most difficult problem to decide between installing an isolated plant and contracting for central station service.” That’s from Knowlton, “The central station and the isolated plant,” Cassier’s Magazine, 32 (August 1907).  Here are a couple of quotes I liked:

To the modern central station man it seems preposterous that scores of small installations, often poorly operated, with wretched load factors, inferior supervision and an oft-times reckless disregard of fixed charges, should be tolerated by keen business men.  Duplication of generating capacity seems to him an idle waste of capital.  But the incubus of distribution cost sets the limit to the minimum profitable power rate, and far too often there is a lack of exact information as to the cost of distribution to particular customers.  The problem of ascertaining it is one of the utmost difficulty, as far as making its influence felt on specific rates is concerned, but it is one of the most fascinating questions in the field of modern electrical engineering.

I’d say that possibilities for distributed energy resources linked with smart grid capabilities makes this question once again “one of the most fascinating questions in the field of modern electrical engineering,” at least within the sub-field of power systems engineering.  Here’s another quote:

No one dreams of the extinction of the central station; it stands upon the solid foundations of maximum potential generating economy and minimum inconvenience to the customer, and even in the face of complex distribution charges and rate making processes which a none too friendly public finds difficult to understand, there will always be a large clientele for the commercial company to supply.

As history has it, the superior economics of the central station approach helped it dominate the electric power industry.  But superior economics in general doesn’t mean superior in every specific case, and changing technologies and energy prices means that all large power consumers should ask themselves the “make or buy” question from time to time, or as Knowlton puts it: central station or isolated plant?

NOTES: The Knowlton article was found via a footnote in John Neufeld, “Price discrimination and the adoption of the electricity demand charge,” Journal of Economic History, Vol. 47, No. 3 (Sep., 1987).  Cassier’s Magazine volumes are available online via Google Books (link to the Knowlton article in volume 32).

Interested readers might also check out The Isolated Plant magazine, first published in December 1908.  The lead article in volume 1, issue 1: “The central station vs. the isolated plant: their respective fields,” by Percival Robert Moses.  (Moses begins, “Has the isolated plant any logical right to exist at present, and if so, is it’s right only a passing one of a few years duration?”)

The smart grid and the advance of civilization

May 13, 2010

Michael Giberson

Scientific American has an article on the start-up pains associated with smart grid development:

Only one thing is worse than the lights not coming on when the switch is flicked—and that’s the lights going out right afterward. The fact that the problem is most often a burned-out lightbulb is testimony to the reliability of what’s sometimes called the world’s largest machine—the U.S. transmission and distribution grid for electricity.

This made me laugh:

“If Alexander Graham Bell returned to Earth today, the progress in telecommunications over the last 125 years would be mystifying,” said Robert Catell, chairman of the New York State Smart Grid Consortium, at a smart grid event in New York City at New York University (NYU) in February. “If Thomas Edison came back today, not only would he recognize our electricity system, he could probably fix it” when problems arise.

Probably not true. After all, most of the grid is based on alternating current (AC) technology, but Edison was a proponent of and best understood direct current (DC).  Now if Catell would have said Nicolai Tesla, that would have been both funny and true.

The article mentions many trials and early advanced metering programs, emphasizing the costs and uncertain benefits.  Catell is quoted again, saying, “An educated and informed consumer is the best weapon in the war against energy demand, and the smart grid is the best way to educate the consumer.” Some of the examples in the article have benefits coming from having consumers act in response to information provided (via the meter, email and even an in-home orb that glows different colors depending on the price of power).

But engaged, immediate consumer response to changing prices is likely only to play a small part within the bigger energy picture.  People (who are not energy policy geeks or early adopters) have too many other things to do.  As Alfred Whitehead said of civilization generally, consumer engagement in the electric power industry will advance “by extending the number of important operations which we can perform without thinking about them.”

More smart grid insight

April 21, 2010

Michael Giberson

According to Accenture, 46 percent of consumers surveyed said they didn’t want smart grid-based energy management systems if it leads to higher electricity bills.  My guess is that the other 54 percent of consumers didn’t understand the question.  The summary distributed by Accenture contains several other bits of should-be-obvious information – consumers are concerned about data privacy, consumers want to be compensated if utilities can remotely turn off appliances, consumers want to be able to locally reverse remote utility cut-off instructions – but even as many of the results seem obvious, it still adds up to some more-than-obvious insight into what consumers want. The FT Energy Source blog also comments on the report.

At the Searching for Insight blog, Gary Hunt offers a consumer’s perspective on smart grid developments informed by years working in energy and information technology businesses.  See his:

Two stories about integrated utility smart grid programs

April 20, 2010

Michael Giberson

Obviously the electric utility industry is very much in the experiment and learning phase (also known as “trial and error”) of the smart grid.  Two examples are provided by PG&E in California and Xcel in Colorado.  It is tempting to rush to judgment on the impossibility of an efficient, well-run, customer-centric smart grid project implemented by rate-regulated, vertically-integrated electric utilities.  I’ll resist that temptation for now, but in the meantime consumers ought to ensure that whatever their local regulated monopoly is doing for (to?) them on the smart grid front doesn’t impede their ability to benefit from the rapidly coming consumer-centric smart grid future.

To that end, consider Toby Considine’s remarks in “Punch and Judy and Energy Usage“:

The real contest is over control of the customer interface, and thereby of the customer. Today’s Google Energy and Microsoft Hohm pose no threats to the control of the customer by the utility. The utilities still can gate access to the back-end energy markets. Control of energy information prevents both intermediation and disintermediation in the energy market. Utilities also are desperate to justify their AMI investments at a time when many are calling for moratoriums and delays in deployment; AMI is part of a seamless model that includes control of the customer’s home as well as of access to information.

[...] The challenge for today is to ensure both backward compatibility with OpenADE and today’s infrastructure and forward compatibility with the unimagined future. That future will support disruptive business models as well as technologies. And that’s why the fights are so fierce over something that appears so simple.

A lot is skipped in the “[...]” so read the whole thing if you want to know more.  An important issue for consumers is that regulated utilities and their regulators do not do “disruptive business models” very well.
