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

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.

Smart Meters Need Effective Electricity Pricing to Deliver Their Full Benefits

Co-authored by Kristina Mohlin, Economist

walletSmart meters, which provide detailed electricity use data throughout the day, are a critical piece of a smarter, more resilient 21st 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 »
