The Disconnect in Electricity Pricing
There is a significant disconnect between the cost of generating electricity and the flat rates that consumers pay, leading to inefficiencies in energy use. During low demand, only the cheapest power plants operate, resulting in low wholesale prices, while high demand requires the use of more expensive plants, which drives wholesale prices up. However, consumers pay a fixed rate and lack the incentive to reduce or shift their electricity usage during peak hours, thus exacerbating the strain on the grid. This inefficiency leads not only to higher overall costs but also to the construction of unnecessary power plants that ultimately drive up retail rates for consumers.
Advantages and Challenges of Time-Varying Pricing
Time-varying pricing models, such as time of use and critical peak pricing, seek to align consumer prices with the true cost of electricity generation, incentivizing users to shift their energy consumption to off-peak times. Time of use pricing involves predetermined rates for peak and off-peak hours, while critical peak pricing provides notifications for specific high-demand events when prices spike. Although these models can help reduce peak demand and improve efficiency, challenges exist, particularly with real-time pricing, which exposes consumers to significant price risks during extreme market conditions. As demonstrated during Winter Storm Uri in Texas, consumers participating in real-time pricing faced exorbitant bills due to sudden price increases, highlighting the need for careful design in rate plans to ensure affordability.
The Importance of Simplicity in Pricing Models
Research indicates that simpler pricing programs can yield more reliable savings compared to complex models that introduce numerous pricing tiers. Utilities often face the risk of 'overfitting' when attempting to predict electricity prices based on historical data, resulting in a mismatch between past and current pricing patterns. As a result, simple models, such as having just two or four pricing tiers, tend to provide more stable and predictable incentives for consumers to adjust their usage. This suggests that instead of complicating pricing structures, utilities should focus on maintaining clarity and predictability in their pricing programs to effectively encourage efficient energy use.
Time-of-use electricity rates can save consumers money and optimize renewable power. But they can backfire if not carefully designed.

A notable feature of the U.S. electricity system is the disconnect between the cost of generating electricity and the prices most consumers pay for power at any given time. Flat-rate pricing, where consumers pay the same rate for power regardless of demand, discourages efficient electricity use, leading to increased strain on the grid. As concerns about reliability, cost, and climate impacts grow, efficient electricity use is more important than ever.
Kleinman Center Faculty Fellow Arthur van Benthem explores time-varying electricity rates, where prices change with demand, as an alternative to flat rate pricing. Van Benthem, a co-author of new research on the topic explains the potential of time-varying pricing to reduce grid costs and enhance renewable energy. He also explores the potential downside to such rates, which can fail to deliver expected benefits or even backfire if not designed with a focus on simplicity and usability.
