Market Forces

Originally posted on EDF’s Energy Exchange.

Last 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.

Two quick questions:

Do you think climate change is an urgent problem?

Do you think getting the world off fossil fuels is difficult?

If you answered “Yes” to both of these questions, welcome. You’ll nod along, occasionally even cheer, while reading on. You’ll feel reaffirmed.

You are also in the minority. The vast majority of people answer “Yes” to one or the other question, but not both.

If you answered “Yes” only to the first question, you probably think of yourself as a committed environmentalist. You may think climate change is the issue facing society. It’s bad. It’s worse than most of us think. It’s hitting home already, and it will strike us with full force. We should be pulling out all the stops: solar panels, bike lanes, the whole lot.

You’re right, in part. Climate change is an urgent problem. But you’re fooling yourself if you think getting off fossil fuels will be simple. It will be one of the most difficult challenges modern civilization has ever faced, and it will require the most sustained, well-managed, globally cooperative effort the human species has ever mounted.

If you answered “Yes” only to the second question, chances are you don’t think climate change is the defining problem of our generation. That doesn’t necessarily mean you’re a “skeptic” or “denier” of the underlying scientific evidence; you may still think global warming is worthy of our attention. But realism dictates that we can’t stop life as we know it to mitigate a problem that’ll take decades or centuries to show its full force. Look, some people are suffering right now because of lack of energy. And whatever the United States, Europe or other high emitters do to rein in their energy consumption will be nullified by China, India and the rest catching up with the rich world’s standard of living. You know there are trade-offs. You also know that solar panels and bike lanes alone won’t do.

You, too, are right, but none of that makes climate change any less of a problem. The long lead time for solutions and the complex global web of players are precisely why we must act decisively, today. Read More »

Smart meters, which provide detailed electricity use data throughout the day, are a critical piece of a smarter, more resilient 21^st century energy system. But they are not a cure-all for modernizing our antiquated power grid.

In Matthew Wald’s recent New York Times article, entitled “Power Savings of Smart Meters Prove Slow to Materialize,” he argues that smart meters have failed to produce measurable savings. And we agree – but not because smart meters themselves have failed. Rather, most customers with smart meters don’t have access to people-powered, or time-variant, electricity pricing, which creates opportunities to save money. This is a missed opportunity for customers, utilities, and the environment.

Time-variant pricing better reflects electricity costs

Throughout most of the country, the price paid for residential electricity is the same regardless of the time of day when it’s consumed. This arrangement is a byproduct of an earlier era, one in which electricity information was difficult to convey and the actions of individual customers was impossible to gauge in real time. In practice, electricity is actually dirtier and more expensive to produce and transmit at certain times of the day, particularly when everybody wants it – for example, at 6pm during a heat wave when customers are cooling their homes. Also, during this high-demand time, energy prices spike and electric utilities flip on expensive and dirty fossil fuel “peaker” power plants to meet energy demand. From an economic point of view, it would be more efficient for electricity used at these peak demand times to have a higher price. Read More »
