Utility regulators frequently focus as much or more on the distributional impact of electric rate structures as on their efficiency. The goal of protecting low-income consumers has become more central with recent increases in wholesale power costs and anticipation of significant costs of...

Since the 1970s, high volumetric (per kilowatt-hour) electricity prices have been justified in many policy discussions as encouraging more efficient use of electricity and placing more of the cost burden on those who are less prudent in their use. The argument has been used in support of...

This study examines a field experiment in Texas that includes pricing and informational interventions to encourage energy conservation during summer peak load days when the social cost of generation is the highest. We estimate that our critical peak pricing intervention reduces electricity...

Recent efforts to restructure and partially deregulate electricity markets have renewed interest in understanding how consumers respond to price changes. Several interrelated problems complicate demand analyses of these markets, including nonlinear pricing, heterogeneity in households' price...

Future electricity systems with tight constraints on carbon emissions will rely much more on wind and solar generation, with zero marginal cost, than today. We use capacity expansion modelling of Texas in 2050 to illustrate wholesale price distributions in future energy-only, carbon-constrained...

In electricity markets, generators are rewarded both for providing energy and for enabling grid reliability. The two functions are compensated in separate markets: energy markets and ancillary services markets. We provide evidence of changes in the fuel mix in the energy market that is driven by...

One of the most critical concerns that customers have voiced in the debate over real-time retail electricity pricing is that they would be exposed to risk from fluctuations in their electricity cost. The concern seems to be that a customer could find itself consuming a large quantity of power on...

Adoption of real-time electricity pricing -- retail prices that vary hourly to reflect changing wholesale prices -- removes existing cross-subsidies to those customers that consume disproportionately more when wholesale prices are highest. If their losses are substantial, these customers are...

We study price convergence between the two major markets for wholesale electricity in California from their deregulation in April 1998 through November 2000, nearly the end of trading in one market. We would expect profit-maximizing traders to have eliminated persistent price differences between...

This paper argues that the market rules governing the operation of the England and Wales electricity market in combination with the structure of this market presents the two major generators National Power and PowerGen with opportunities to earn revenues substantially in excess of their costs of...
