Stakeholders Gather to Discuss How Time-Variant Electricity Pricing Can Work in New York

Originally posted on EDF's Energy Exchange.

new-york-540807_640Last week, Environmental Defense Fund (EDF) co-hosted a successful forum on residential time-variant electricity pricing – which allows customers to pay different prices for electricity depending on when it is used – within the context of New York’s ‘Reforming the Energy Vision’ (REV) proceeding.’

Co-hosted with the New York Department of Public Service and New York University’s Institute for Policy Integrity, the full-day forum, “On the REV Agenda: The Role of Time-Variant Pricing,” brought together more than 150 regulators, utility executives, academics, and other stakeholders to explore how residential time-variant pricing works, what it can accomplish, and how best to implement it. Below is a recap of some of the high-level takeaways from the forum.

How time-variant pricing (TVP) works

One of EDF’s objectives has been to improve the efficiency of the electricity industry by pursuing a market-based approach to electricity pricing. In most well-functioning markets, the cost of making a product and its relative scarcity is reflected in the price. For example, a door is more expensive than the wood with which it is made in order to reflect the labor costs involved. Similarly, strawberries are more expensive during the winter because they are less abundant during that time. Customers understand that prices vary with production costs and over time, yet neither of these elements gets reflected in how residential customers currently pay for electricity.

We can get better biodiversity outcomes from environmental markets

This post was co-authored with Sara Snider and Stacy Small-Lorenz. 


Join us in Washington, DC on December 8 for a pre-ACES Conference workshop- “Getting Better Biodiversity Outcomes from Coordinated Environmental Markets.”  We welcome anyone interested in exploring the space where environmental markets, including habitat markets, interact with each other and conservation programs. Come investigate with us how biodiversity can benefit from the optimal design and coordination of markets.

Getting Better Biodiversity Outcomes from Coordinated Environmental Markets is a free pre-conference workshop for ACES Conference attendees.

Monday, December 8, 2014


Washington, DC

Register here for the ACES Conference and sign-up for this workshop!

Aligning Incentives to Maximize Environmental Benefits

Environmental markets have the potential to enhance and conserve key elements of ecosystems; however, this requires coordinated and informed decision-making. During the workshop, we will explore the evolution of habitat markets and how such markets should be designed to achieve the greatest net benefit, covering both biological and regulatory considerations of habitat market design. We will also discuss scenarios in which it could be appropriate to combine habitat markets with other markets (e.g. water and air quality) to create added-value incentives.  We will emphasize topics such as the interface of markets with federal conservation programs, the challenge of establishing baselines for landowners enrolling in habitat markets, as well as the economic and legal challenges of stacking.


Engage with Environmental Market Experts around Case Studies

Environmental markets experts will lead us through an engaging discussion of the challenges and opportunities for biodiversity markets and stacking in moderated panel and breakout discussion format. Confirmed panelists include:

  • Jessica Fox, Senior Project Manager, Electric Power Research Institute
  • Kevin Halsey, Senior Consultant, EcoMetrix Solutions Group
  • Chris Hartley, Environmental Markets Analyst, USDA Office of Environmental Markets
  • Rene Henery, California Science Director, Trout Unlimited
  • Alex Pfaff, Professor of Public Policy, Economics and Environment, Duke University
  • Morgan Robertson, Assistant Professor, University of Wisconsin
  • Jeremy Sokulsky, Chief Executive Officer, Environmental Incentives
  • David Wolfe, Director of Conservation Strategy, Environmental Defense Fund
  • Stacy Small-Lorenz, Senior Scientist, Environmental Defense Fund (Moderator)

Workshop participants will have the chance to discuss basic and complex questions around these topics by working through real-life scenarios. We will touch upon potential pitfalls, such as double-dipping, legal inconsistency, and market incompatibility, as well as the challenge of establishing baselines for landowners.  As environmental markets move forward to incentivize better biodiversity outcomes, we must be ready to collaborate and coordinate with fellow ecosystem service professionals to achieve real success.  Let’s get started at the ACES Conference!

Enter the Conversation

EDF has a long history of creating innovative market-based solutions to our environmental challenges, including the historical trading program in the 1990s that dramatically decreased acid rain and reduced exposure to harmful pollutants. Now, we continue to develop multiple markets in order to maximize environmental benefits, such as habitat restoration and carbon sequestration. A Community on Ecosystem Services’ (ACES) Conference this December provides an in-depth forum for exploring these topics with representatives from government, academia, conservation NGO’s and the private sector.

Gross Domestic Product: Grossly incomplete, but we can fix it

Via EDF Voices. This first appeared online in an article posted at

Gross Domestic Product (GDP) is broken. Robert F. Kennedy said as much in his first major presidential campaign speech. Simon Kuznets, the father of GDP, acknowledged its shortcomings. GDP is an imperfect indicator of human well-being at best, and outright misleading at worst.

Still, we shouldn’t scrap GDP and start over.

Up to a point, GDP does tell us important facts about people’s lives, livelihoods and aspirations. Living on a dollar a day is miserable no matter how you look at it.

Choking on economic growth, of course, is equally bad. There are a few simple, well-established steps we ought to take to bring GDP closer to where we should be. That, by the way, isn’t “Green GDP” or “green accounting.” It’s honest accounting.

Start with accounting for the true value of natural assets still in the ground. We don’t “produce” coal. We extract it. And the fact that the ton of coal extracted today is no longer there for the taking tomorrow should show up in our national income accounts. A ton of West Virginian coal adds about $30 to GDP. Honest bookkeeping would decrease that amount to $15. The same holds for oil, trees, water and all the other valuable natural assets that fuel our economy but are largely treated as free in our GDP accounting.

Then quickly move on to pollution. Every ton of coal, every barrel of oil causes more in external damages than it adds value to GDP. Properly measured GDP ought to reflect that fact.

In the end, policy makers should expand their horizon and look at a dashboard of indicators to get a fuller picture of the true state of the economy, society and the planet. Yet when it comes to GDP itself, the name of the game is fixing it rather than scrapping it. We know how to do that. The U.S. Bureau of Economic Analysis is at the ready. Let’s have a go at it.

The Nuts and Bolts of California’s First Greenhouse Gas Auction

This article was originally posted at California Dream 2.0.


Following today’s California Air Resources Board’s (CARB) board meeting, the next major milestone in California’s efforts to reduce greenhouse gas (GHG) emissions is on November 14th, when California will hold the first auction of carbon allowances for the Global Warming Solutions Act (AB 32) cap-and-trade program. EDF has closely followed the steps CARB has taken to prepare, including participating in their successful “practice auction” this past August.  In order to shed some light on the nuts and bolts of how these auctions will work and the process going forward, we’ve put together an Auction FAQ factsheet to help answer some basic questions.

Why is CARB Auctioning CO2 Allowances?

In terms of allowance distribution, the AB32 program includes a combination of free allocation and auctioned allowances.  While it is the cap that ensures that the targeted quantity of emission reductions are achieved – regardless of the choice of type of allowance distribution – there are important differences between auctioning and free allocation relating to issues such as transaction costs, market power, price certainty, and distribution of allowance value.

Perhaps most importantly, auctioning allowances creates proceeds that can be invested in a variety of ways to further the goals of AB32 – for example, financing emission reduction projects in either capped or uncapped sectors, keeping energy prices down, or preparing for the impacts of global warming.  In addition, twenty-five percent of proceeds are actually required to be used in ways that benefit disadvantaged communities.

Another advantage of auctioning CO2 allowances is that it guarantees that all regulated entities have access to allowances on an equal footing. By holding an auction, California ensures that both large and small companies have access to allowances under the same terms, thus reducing the risk that the market becomes dominated by a few big players.

How the Auction Works

The California auction will be using a single-round, sealed-bid, uniform-price format. Under this format, companies submit confidential bids for a specific amount of allowances at specific prices (also called a bid schedule). The highest bidder is allocated their requested quantity of allowances first, then the second highest bidder, etc., until there are no more allowances.  Winning bidders receive the quantity of allowances they bid for at the uniform settlement price, which is determined as the value of the lowest winning bid – or more simply, the price at which the market clears. Regardless of their original bids, all winning bidders pay the same price. This auction format creates a clear market price, which is crucial for investors.

Using Auction Revenue to Further Emissions Reductions

There are abundant opportunities to invest the auction proceeds into sectors that deliver greenhouse gas reductions in California – from clean energy to clean transportation, energy storage and clean tech finance and investment. Not only do these investments further California’s greenhouse gas reduction goals, they can also provide considerable economic benefits, as well as substantial health co-benefits, while helping set California’s path towards sustainable economic growth. To learn more about investing AB32 auction proceeds to grow California’s clean economy, read the EDF Invest to Grow report.

Auctions will play an important role in California’s cap-and-trade program; they encourage a more stable market and create proceeds that can be used to make California’s efforts to cut climate change pollution even more effective. For more details about how the auctions are designed, how the bidding process works and what to expect on November 14th, see EDF’s Auction FAQ factsheet and the California Air Resources Board’s website (here).

All Systems Go for California’s Carbon Auction!

By Emily Reyna. This article was originally posted at California Dream 2.0.

Last Thursday, California took an important step towards finalizing a major component of the state’s effort to cut climate change pollution, an economy wide cap-and-trade regulation that establishes a price on carbon pollution.  Along with an expert from EDF’s economics team, Jonathan Camuzeaux, I had the opportunity to participate in the first ever public “practice” auction for the Global Warming Solutions Act cap-and-trade program – and it was a runaway success.

The goal of yesterday’s practice was to test the new online exchange where users will be able to bid on "carbon allowances" starting in November of this year.

EDF decided to submit the paperwork to be among the first users to test the new auction system since there is a lot riding on the cap-and-trade program working. Once fully operational, California’s cap-and-trade market will introduce the most cost-effective way to reduce climate pollution, protect public health, and spur clean tech innovation.

Here's how it worked:

During the practice auction we walked through a checklist of 33 tasks EDF designed to test the functionality of the system. What we found was that the auction system run by the California Air Resources Board (CARB) works much like other secure websites, such as that of an on-line bank or retailer.  Users sign in with a secure username and password and during the pre-determined open hours (bidding window), bidders place an order for as many emissions allowances as they want to buy, though only a certain number will actually be sold.  Bids from other organizations are rightfully kept private and hidden from view – making this a “sealed-bid” auction platform that is based on the system designed and currently in use in North America’s other cap-and-trade program for greenhouse gas (GHG) pollution in the Northeast.

During the bidding window, users were free to modify or rescind bids.  Once the bidding window closed all bids were final.  Since yesterday was only practice though, no money was actually exchanged or allowances sold once the bidding ended.

Our assessment:

From top to bottom, the AB 32 cap-and-trade auction system was easy and straightforward to use. Though we witnessed a few minor annoyances – such as being able to upload multiple bids at one time but only being able to delete one at a time – all of the market critical aspects were running well from our vantage point.  The next step will be for CARB to evaluate the bids and determine which are accepted and rejected based on the publically available market rules.

In all, after three hours of testing, our consensus is that the system works, and works well. California is ready to launch a new era of innovation, job creation, and economic stability. It is inspiring to see California taking climate action, and we believe success here will inspire other states, regions, and nations to develop similar climate programs.

Spinning facts to suit industry interests: New California Manufacturers & Technology Association report is full of holes

By Jamie Fine, PhD and Ruiwen Lee

Jamie Fine is EDF’s Senior Energy economist, and a graduate of UC Berkeley’s Energy Resources Group; Ruiwen Lee is an economics fellow and graduate of Princeton University’s Woodrow Wilson School of Public and International Affairs. Originally posted on EDF's California Dream 2.0 blog.

California’s energy and climate change policies have saved the state over one hundred billion dollars and dramatically reduced levels of environmental pollution since the early 1970’s. Yet these policies have been in the crosshairs of industry for decades, despite their demonstrated success. It’s not surprising that the latest study sponsored by the state’s main manufacturing lobbying group, the California Manufacturers and Technology Association (“CMTA”), ignores the achievements of these landmark policies while attempting to downplay the benefits of new laws that protect human health and the environment.

EDF’s team of economists looked behind the curtain of CMTA’s most recent tirade against clean air laws and found cherry-picked assumptions, secret modeling calculations, and confusion over basic economic principles. Accordingly, while CMTA’s new report maintains that it modeled the impacts of California energy and climate policies on the state’s economy, the results more closely resemble CMTA members’ manufactured products than actual economic analysis.

Cherry-picked data – CMTA’s report is based on the impact of seven different policies currently underway in California:  The 1) Low Carbon Fuel Standard (“LCFS”), 2) Pavley II car standards, 3) SB 375, 4) the Renewable Portfolio Standard (“RPS”), 5) Combined Heat and Power (“CHP”) standards, 6) new efficiency measures, and 7) the Global Warming Solutions Act of 2006 (“AB32”).

Though these policies have been carefully designed and the economic impacts studied, modeled, re-studied, re-modeled, and peer reviewed, the report’s analysis assumes significantly lower benefits and higher costs than nearly every other peer-reviewed analysis that currently exists.  With these new assumptions, each described in a mere sentence or two, the goal seems to have been to engineer a flimsy model that puts AB32 into a bad light.

Even more subtle assumptions are not immediately obvious at first glance. For example, in the electricity model, the report uses a simplistic “average change in electricity demand”, based on the ten-year historical decline in electricity use per unit of state output, to project future electricity demand.  However, this model does not consider the reduction in electricity demand from the energy efficiency measures that have only recently been implemented, or yet to be imagined by innovators – meaning the modeling output undercounts savings from day one.

In addition, this model is posing extremely pessimistic assumptions about new transportation fuels and the California LCFS.  These same assumptions are at the heart of a recent oil industry report, and fail to take into account policy-inspired innovation that will lead to newer transportation fuels in adequate supply.  As previously discussed here,  here and here, these pessimistic assumptions aren’t grounded in the reality of market incentives for innovation, making the CMTA report eerily similar to other oil industry “sky-is-falling” reports – this one just has a different cover.

Finally, like other faulty anti-AB 32 analyses that have been debunked, this newest CMTA piece fails to take into account the full range of benefits that can be achieved by implementation of California’s regulations.  For example, the analysis only calculates the costs to carbon-intensive commodities, ignoring the positive demand impacts on clean products and services.

Secret modeling calculations – The output presented in this new paper is based on an internally designed model that claims to weave together “24 interacting models that measure the combined impacts of AB 32.”  However, nothing more is presented than a few spreadsheets of model output and some graphs.  This amounts to a clear admission that the model simulated the operations of an entire economy and then offered the output as fact, without any discussion of range or uncertainty.  Simply put, CMTA’s new report says, “trust me” even though the findings are vastly different from prior, peer-reviewed scholars.

Confusion over basic economics – The principles that underpin cost analysis, though complex, are fundamental to the accuracy of the overall output of economic models.  In this report, CMTA has apparently gotten some of those basic principles backwards, meaning that the modeling results are likely to be fundamentally flawed.

For example, in the description of their direct cost estimation model for electricity, the report wrongly concludes that, “the cost of electricity is decreased by efficiency measures, which drives up demand.” In fact, it is the other way around – efficiency measures shift the demand curve down (given any electricity price, consumers use less electricity than before efficiency measures are implemented), so the cost of electricity is decreased, even as the quantity of electricity consumed is further reduced.

Model inconsistencies – In another area of the report, where it separately modeled electricity and natural gas price and demand impacts, it appears there is double counting and inconsistent assumptions due to confusion over the linkages between commodities markets. For example, even as the report predicts electricity generation from natural gas will decrease by 40% from 2012 to 2020 (Appendix D-6), overall natural gas demand will increase by 6% over the same period (Appendix E-1).  A simple question underpins the potential error of these inputs: when so much electricity is currently made using natural gas, how can the state reduce its use in the power sector by 40% while using so much more in the aggregate?

In yet another example, the report purportedly uses a simple summation of impacts (Appendix C-2) from modeling outputs to calculate policy “costs”.  However, since at least some of the commodity markets that have been analyzed are substitutes for one another, a simple summation method will almost certainly result in double counting. The report doesn’t make clear which commodity markets were modeled based on direct cost estimations, and which were separately modeled based on aggregated data – a wholly separate problem from the one described above.

The bottom line is, this report is deeply flawed in its analysis and its presumptions. If your summer reading list includes fiction, then by all means take the time to read it. But if you are looking for a well-documented and peer-reviewed examination of California’s anti-pollution laws, this report doesn’t make the grade.
