Deregulation of the electric power industry in the United States is the process of replacing traditional regulated monopoly structures for generation, transmission, and distribution with competitive markets and new institutional arrangements. Reform efforts have sought to introduce competition among generators, establish independent transmission operators, and separate utility functions to improve efficiency, investment, and consumer choice. Policy design has varied across jurisdictions, producing a patchwork of outcomes involving federal actors like the Federal Energy Regulatory Commission and state actors such as the California Public Utilities Commission.
History and Background
Early electric service in the United States developed under local franchise monopolies managed by companies such as General Electric-linked utilities and municipal systems like Los Angeles Department of Water and Power. The regulatory model matured under state public utility commissions including the New York Public Service Commission and the California Public Utilities Commission, guided federally by the Federal Power Act and the PURPA. Beginning in the 1990s, influenced by privatization trends in the United Kingdom and restructuring in the European Union, scholars and policymakers from institutions like Harvard University and Massachusetts Institute of Technology advocated market-based reform implemented by actors such as FERC and state legislatures.
Federal and State Regulatory Framework
The federal-state split centers on jurisdictional authority: the Federal Energy Regulatory Commission oversees wholesale sales and interstate transmission under the Federal Power Act, while state public utility commissions regulate retail rates and distribution, exemplified by the New York Public Service Commission and the Texas Public Utility Commission of Texas. Federal actions, including FERC Order 888 and FERC Order 2000, promoted nondiscriminatory access and formation of Regional transmission organizations like PJM Interconnection, MISO, and the CAISO. State statutes such as the PURPA and state restructuring laws—e.g., the California Assembly Bill 1890—shaped retail choice models in jurisdictions like Texas and Pennsylvania.
Restructuring Models and Market Mechanisms
Restructuring created diverse models: full retail competition as in Texas under Senate Bill 7, partial competition with rate freezes like California Assembly Bill 1890, and retained vertically integrated utilities subject to wholesale competition. Market mechanisms included energy-only markets (e.g., ERCOT), capacity markets administered by PJM Interconnection and NYISO, day-ahead and real-time markets, and ancillary services markets. Vertical unbundling, independent system operators such as ISO New England, and market monitoring by entities like the North American Electric Reliability Corporation sought to mitigate market power problems highlighted in the Enron era.
Major Reform Waves and Key Legislation
Key federal actions included FERC Order 888 (1996) and FERC Order 2000 (1999), which required open transmission access and encouraged Regional transmission organization formation. Congressional actions such as debates over the Energy Policy Act of 1992 and later Energy Policy Act of 2005 influenced market development and reliability standards. State reforms in the 1990s and 2000s—California's restructuring under Gray Davis, Pennsylvania's restructuring law, and Texas liberalization—constituted major waves. The collapse of merchant entities like Enron and the California electricity crisis prompted legislative and regulatory responses emphasizing market oversight and consumer protection.
Impacts on Prices, Reliability, and Investment
Empirical assessments show mixed outcomes. In some regions, wholesale price competition lowered marginal costs and stimulated entry by independent power producers such as Dynegy and NRG Energy, while in others prices spiked during events like the California electricity crisis and the 2000–01 California energy crisis. Reliability outcomes varied: institutions like NERC and regional entities addressed blackout risks after events including the Northeast blackout of 2003. Investment patterns shifted toward gas-fired combined-cycle plants and, later, renewables using tax incentives like the Investment Tax Credit and regulatory constructs such as renewable portfolio standards in states like California and New Jersey.
Notable State Cases and Regional Experiences
California’s restructuring culminated in the California electricity crisis, with market manipulation by corporations including Enron and emergency interventions by Governor Gray Davis. Texas’s model under ERCOT emphasized retail choice and an energy-only market that produced fast entry but also vulnerability during extreme events like the February 2021 Texas power crisis. The Northeast and Mid-Atlantic region, coordinated through PJM Interconnection, developed sophisticated capacity markets. New England’s experience under ISO New England showcased integration challenges for renewable integration and transmission planning coordinated with entities like the New England Governors and Eastern Canadian Premiers.
Criticisms, Challenges, and Future Directions
Critics point to market manipulation, inadequate capacity signals, and misaligned incentives highlighted by cases involving Enron and crises in California and Texas. Ongoing challenges include integrating variable renewable resources promoted by policies in California and Hawaii, ensuring transmission investment across regions such as MISO and PJM, and aligning federal and state objectives amid debates in forums like FERC and state legislatures. Future directions emphasize capacity reform, market design for storage and distributed resources, grid resilience against storms like Hurricane Sandy, and regulatory innovation spurred by companies such as Tesla, Inc. and NextEra Energy and research institutions including National Renewable Energy Laboratory.
