Guest Post: The importance of engaging electricity consumers

My partner at M.Cubed Steven Moss wrote this editorial for The Potrero View on how we need to engage consumers when developing a vision of how the electricity future might evolve:

Multiple corporate monopolies have emerged, thrived, and withered over the last hundred years. Railroads, telegram and telephone services, air transportation, network television and newspapers all had highly lucrative heydays, but were ultimately cut down to size by a combination of government anti-trust activities and new technologies. Today there’s a plethora of transportation, communication, information, and entertainment services, most offered at lower cost or with greater value than what was on the former cartels’ menu.
The societal conversation continues over how to best manage quasi-monopolies, like cable and Internet services. Water utilities are struggling with how to pay for themselves in an era in which reducing consumption is essential to addressing chronic scarcity. But the monopoly sector most ripe for rapid change is the almost a half-trillion dollar electricity sector.
Throughout the U.S. electricity is provided by a mix of municipal, cooperative, and investor-owned utilities (IOUs), each with a lock on delivering large aspects of the service in their home territories. In California the three large IOUs — San Diego Gas and Electric, Southern California Edison, and Pacific Gas and Electric (PG&E) — have carved up the lion’s share of the state’s monopoly electricity market. All of them face a business model that’s been buffeted by the rapid policy-driven onsite of renewables and the emergence of other technologies that aren’t as dependent on a large, capital-intensive spoke — fossil fuel or nuclear power plant — and wheels — transmission and distribution — system to operate.
Today, a home or business can install devices to capture sunshine or wind and cope with intermittent power flows by managing the timing of their energy consumption and installing a storage device, which could include harnessing the battery in the electric vehicle parked in the garage. These types of systems may work best when they’re combined at the multiple-neighborhood level, to create a portfolio of resources that can reduce the risk that the failure of one device will have catastrophic outage consequences. The optimal size for a next generation grid may be roughly half the size of San Francisco, a back-to-the-future system that mirrors the more than 100 small service providers that combined more than a century ago to create PG&E.
Institutional change is tricky, though, when it comes to electricity. Although rates are high in California, outside the Central Valley in the summer, household bills are generally modest as a result of the state’s mild climate. There’s solid service reliability, with the IOUs generally doing a fine job restoring post-storm outages. And, thanks to public policies, low-income families are provided substantial subsidies, while the grid has grown increasingly green. Outside San Francisco — and post natural gas-disaster San Bruno — where tilting at PG&E is an ideological battle rather than an economic one, these characteristics serve to mute the potential for widespread ratepayer revolt, and encourage consumer advocacy groups to protect the existing monopoly system.
Yet without change, electricity service is poised to get much more expensive, and probably less green. Renewable intermittency — production drops when the sun doesn’t shine — doesn’t match with the current system, creating gaps that could be plugged by costly and polluting fossil fuel power plants, eroding much of the environmental gains achieved over the past decade. Despite substantial technological innovation which should spur price competition, utility rates are consistently rising, in part because two competing paradigms — New Age renewables, and Industrial Age fossil fuels — are being simultaneously pursued for political reasons.
The seeds of a solution are in creating more knowledge. Consumers are almost entirely ignorant of how the timing of their electricity use influences costs. Electricity rates don’t reflect the underlying expense — to the environment or grid — of providing service in a given time and place. Since price-based feedback to the IOUs is significantly muted, the monopolies operate as if demand is largely immune to change, and must be met by increasing amounts of generation to ensure reliability.
The pathways we take as the grid wobbles in the face of renewable disruption will determine how much we pay, out of our pockets, and through dirtier air, for the next few decades. Fortunately, there’s a ready way to remold the monopoly electric utility industry: get the prices right. If rates reflected the true costs of service — including greenhouse gas and polluting air emissions — consumers and businesses would take action to change their consumption patterns, aided by high technology companies eager to solve profitable problems. The Internet of Things would become the Energy System of Things, with renewables, storage, and a host of communicating devices connected to optimize energy use in an environmental sustainable way.
Offering transparent electricity prices won’t solve all of the grid’s challenges. But not doing so walls off essential innovation. Renewables and emerging technologies, combined with clever tariffs, could help ensure that California never builds another fossil fuel power plant. The state can protect low-income households from onerous electricity bills, by directly paying for energy efficiency investments, or providing bill credits. A small is beautiful ethos can emerge to rival the large, reliable, monopolies in providing high-quality services. If we get the prices right.

For 100 years, California’s State Water Resources Control Board and its predecessors have been responsible for allocating available water supplies to beneficial uses, but inaccurate and incomplete accounting of water rights has made the state ill-equipped to satisfy growing societal demands for water supply reliability and healthy ecosystems. Here, we present the first comprehensive evaluation of appropriative water rights to identify where, and to what extent, water has been dedicated to human uses relative to natural supplies. The results show that water right allocations total 400 billion cubic meters, approximately five times the state’s mean annual runoff. In the state’s major river basins, water rights account for up to 1000% of natural surface water supplies, with the greatest degree of appropriation observed in tributaries to the Sacramento and San Joaquin Rivers and…

Understanding the Challenges of Modeling AB 32 Policy

A summary of the review of the AB 32 Scoping Plan we conducted in 2008 for EDF.

[From press release] A new study released today concludes that state-of-the-science economic models, including those used for the California Air Resources Board’s economic analyses of California’s Global Warming Solutions Act (AB 32), are not capable of simulating the fundamental changes in California’s economy that AB 32 measures are likely to cause. While critics of ARB claim that costs might be underestimated, this new study shows that many benefits also are not represented by models and more modeling isn’t as useful as consideration of lessons from prior policies and economics literature.

The study is timely because CARB will vote on the Proposed Scoping Plan to implement the Global Warming Solutions Act of 2006 (AB 32) on December 11, less than a week away.

In the new study, Dr. McCann reveals that current techniques…

Identifying the barriers to transportation fuel diversity

Tim O’Connor of EDF writes about the benefits of transportation diversification at EDF’s California Dream 2.0. I think that fuel diversity is a useful objective, but achieving that will be difficult due to the network externalities inherent in transportation technologies. Gasoline and diesel vehicles became dominant because having single-fuel refueling networks is more cost effective for both vendors and customers, and reduce the search costs for drivers to find those stations. Think of how many fueling stations someone might have to pass to reach their particular energy source. Investing in a particular fuel requires a certain level of revenue. Note how many local gas stations have closed because they didn’t have enough sales.

For a more recent example, we can look at cell phone operating systems. Initially each manufacturer had their own system, but now virtually all phones are driven by two systems, Android and iOS, while Windows 8 keeps trying to make inroads.

We need to be very aware of the fueling network economics when pushing for new transportation energy sources. Investing in a system is as much a set of business decisions as a policy decision. One approach might be to focus on using particular fuels in a narrow set of sectors and discourage broad sector-wide use. Another might be to use a geographic focus and to set up means of interconnecting across those geographies.

Yet another misconstrued view of “economics” in the climate change debate

Charles Mann wrote an interesting review of several books on climate change in The Atlantic Monthly. He portrays the debate as “Environmentalists” vs. “Economists.”  Unfortunately he describes economists as relying entirely on using central tendency expected values in standard cost-benefit analyses. And he fails to give economists full credit for creating the cap and trade system that he praises as an effective means of generating the change that is required.

The fact is that many economists are changing the debate on climate change to focus on deep uncertainty, to assess the costs of unlikely but catastrophic outcomes, to design effective technology subsidies, and to focus California’s climate change policies on global goals. All of these are important innovations that are affecting the debate over how to address the risks of potential climate change.

It’s important to recognize that we need to decide to act without full knowledge about whether climate change is driven by human activity or will it be of sufficient consequence to affect our civilization. If we live in a forest and there’s risk from a distant fire, we assess whether we need to buy insurance, clear brush around our house or evacuate. The fire may never come to pass–in fact the probability may be quite low, but we know the catastrophic consequences if it arrives. Is acting now to address climate change risk, both mitigation or adaptation, worth it? Economists have the tools to address this question–the problem is that key individuals in the media such as Charles Mann don’t seem to be aware of these, and so neither does the public or decision makers.

Distribution system operator rising

Two recent papers propose a new approach to managing the distribution grid by creating a “distribution system operator” (DSO). The DSO would control the local low-voltage grid between the substations and the customers’ meters, much as the independent system operators (e.g., CAISO, PJM, MISO, NEISO, NYISO) run the high-voltage transmission grid above the substations. The transmission and distribution system would be run as an open-access system, much as how many natural gas utilities are run now.

Lorenzo Kristov and Paul De Martini have written about this approach, focusing on the technical issues. They are agnostic on ownership, and talking with Kristov (frequently) he sees that the DSO can be either owned by the existing utility or spun off.

Former FERC Chair Jon Wellinghoff and James Tong of Clean Power Finance have addressed the ownership / management issue, proposing that the DSO be independent. They also have proposed that regulated utilities be allowed to own distributed generation on the customer side of the meter.

An important issue yet to be addressed in the creation of (I)DSOs though is transition and sustainability. The creation of ISOs has been politically traumatic, and creating IDSOs will face even more risk-averse political opposition, particularly in the West, after the energy debacle of 2000-01. We’ve also seen that ISOs are not particularly cost sensitive because they are largely insulated from direct cost regulation of the capital assets that they manage (a classic “agency” problem.) Since transmission is such a small portion of overall rates, the ISOs have been able to fly under the radar–but that may change soon.

Finally, it’s not clear how shareholders will view the change in asset ownership, management and returns. I wrote about this previously in the emergence of the “peer to peer” economy. Ensuring that shareholders don’t lose substantial value, even as the risk profile changes, will be key to easing the political process. There are alternative models for easing the asset management transition that is not threatening to current shareholders. There are better models than simply relying on regulated utilities to essentially do more of the same. Market forces are important in driving the innovation needed to transition the electricity system.  More on that another time.

Repost: Californians Can Handle the Truth About Gas Prices

Sev Borenstein writes about the two sides of the argument on whether transportation fuels should be rolled into the cap-and-trade program in January 2015.

I have an observation that that has only been alluded to indirectly in the debate. The main point of the legislators’ letter calling for a delay in implementation is that low income groups may be particularly hit. The counter argument that we need the inclusion of transportation fuels under the cap to incent innovation seems to pit the plight of the poor against the investment risk of wealthy entrepreneurs. We haven’t really done a good job of addressing affordability of the transformative policies that can change GHG emissions. The proposal to use carbon tax revenues to rebate to low income taxpayers has been floated at the national level, but of course that died with the rest of the national cap and trade proposal. A similar proposal was made to mitigate electricity price impacts.

Our state legislators are rightfully concerned about the impacts on those among us who have the least. Nevertheless, that problem is easily addresses with the tools and resources that are already available to the state. Those families and households who now qualify for the CARE and FERA electric and natural gas utilities rate discounts can be made eligible for an annual rebate equal to the average annual gasoline consumption multiplied by the amount of the GHG allowance cost embedded in the gasoline price. This rebate could be funded out of the state’s allowance revenue fund. For example, if the price is increased by 15 cents per gallon and the average automobile uses 650 gallons per year, an eligible household could receive $97.50 for each car.

About 30% of households are currently eligible for CARE or FERA. On a statewide basis, the program would cost about $650 million, which is comparable to the cost for CARE for a single utility like PG&E or Southern California Edison. Those legislators who are most concerned can coauthor legislation to put this program in place.

(BTW, I think the DOE fuel use calculator is outdated–on my many trips to LA I haven’t seen these types of fuel economy changes. My average MPG is pretty much the same no matter how much traffic there is on I-5.  But that’s just a fun fact aside…)

What is the true price for renewable energy power?

The renewable energy market has been in upheaval since the collapse of the financing sector in 2008. The withdrawal of easy money and uncertainty over federal tax policy has increased perceived risk.  Large firms have been shedding renewables subsidiaries and promising newcomers have dropped high-profile projects. Waste Management just sold Wheelabrator, exiting the waste-to-energy market. Brightsource suspended its Hidden HIlls solar thermal project. Much of this activity is driven by the perception that wholesale electricity market prices are falling and the underlying fundamentals will lead to further declines.

This perception is misplaced, however. Short run electricity market prices are falling as natural gas becomes cheaper, and more importantly, fossil fuel generation is squeezed out by increasing renewables and falling demand. However, the electricity marketplace hasn’t yet adjusted to the fact that natural gas generation is no longer the only marginal generation resource. In California, the renewables portfolio standard (RPS) makes at least 33% of the marginal generation from renewable resources. When capital costs are correctly figured in, and more long-term contracts are offered to match those deferred resources, power purchase agreement (PPA) prices for the right types of resources should increase, not decrease.

The problem is that the industry hasn’t been able to adjust its procurement model to reflect this new reality. I think this is coming from a combination of utilities continuing to maintain their monopsony (single buyer) position, risk averse regulatory agencies still relying on an obsolete procurement regulatory process, and those agencies enforcing the monopsony power of the utilities in the name of protecting ratepayers. This may not change until there is public acknowledgement that this situation exists. The difficulty is finding the right stakeholders with enough sway to raise the issue.

What we might expect for diffusion of new decentralized energy technologies?

Technologies and policies that enhance the development of decentralized energy resources have generated increasing interest over the last couple of years.  I’ll write more in the future about what are the underlying drivers, both technological and institutional.

I’ve been interested in the question of where do we stand, and how long might it take for diffusion of these new technologies. We can look back and see how technology transformed lives in just a couple of decades. Compare kitchens from 1900 and 1930; if we walked into the earlier kitchen, most of us would be lost, but we could whip up a meal in 1930.

Or the rapid adoption of autos. In 1909, people could stand in the middle of Pike Street in Seattle and talk:

File:Seattle - Pike Street 1909.jpg

Not so safely in 1930:

Do we stand today at a point just at the onset of a new technological evolution?

One question to be answered is whether our institutional settings will allow these new technologies. In one case, it appears that Germany has already chosen its road. But in the US, whether we rely on central power stations using transmission lines may still be a question in play. That deserves a separate post of its own.

If we assume that we choose the decentralized path, what might we expect in when these technologies are adopted widely. A couple of graphics illustrate historic diffusion rates. This is one from VisualEconomics via The Atlantic:

Another one from Forbes via The Technium shows the parallel development paths (however, I don’t like starting at the year of invention instead of a threshold adoption level):

One might interpret the upper graph as showing accelerating adoption rates. But I interpret the lower chart as illustrating at least two factors that drive diffusion: the relative importance of network infrastructure and the expense relative to individual wealth.  Autos, telephones and electricity all required construction of a large network of roads or wires, often funded with public investment. Individuals can’t choose to adopt the technology until a larger public decision is made to facilitate that adoption.  As to expense, refrigerators and dishwashers were large household investments for many years, and cars are still a large single expenditure. On the other hand, cell phones, radios and televisions quickly became inexpensive which lubricated diffusion. We need another graphic showing how diffusion rates relate to these two different axes.

We are still unsure where decentralized energy technologies will fall among these characteristics. They may seem small and inexpensive, but enough solar panels to power a house will still be several thousand dollars for the foreseeable future. And the how much electric network investment is required to integrate these resources is the center of the debate over technology policies.

Too often studies making forecasts and policy recommendations don’t consider what adoption rates are feasible or probable. However a study comes along and incorporates this concept as its centerpiece. A good example is the Clean Energy Vision Project’s Western Grid 2050 report. Lead by a former colleague Carl Linvill, who’s now at the Regulatory Assistance Project, it looked at several different scenarios for technology diffusion. Such studies give us a better understanding of what’s actually possible rather than what we wish for.
