Deregulation Of Electric Industry Research Articles

Meeting the emerging transmission market segments

In this paper, the authors present an analysis of the components of the emerging deregulated electricity industry which provides a basis for structural classification, with a view toward defining the required support tools.

The Competitive Effects of Transmission Capacity in a Deregulated Electricity Industry

In an unregulated generation market, degree to which generators different compete with one another depends on capacity to transmit electricity between locations. We study impact of capacity on competition among generators. We show that there may be no relationship between effect of a line in spurring competition and actual that flows on line. We then investigate the equilibria that are likely to result as lines between previously unconnected locations are built and expanded. We demonstrate that limited capacity can give a firm the incentive to restrict its output in order to congest into its area of dominance. This analysis is applied to a model of California's forthcoming deregulated market. Our results indicate that at least one firm could have an incentive to strategically induce transmission congestion and that relatively small investments in may yield surprisingly large payoffs in terms of increased competition.

Applying planning models to study new competition: Analysis for the Bonneville Power Administration

An integrated electric utility planning model, the Resource Policy Screening Model (RPSM), was used to project acquisitions from independent power producers made by customers of a US power marketing authority. Bonneville Power Administration (BPA) markets power from dams in the Pacific Northwest to retail utilities. BPA's historical cost advantage has eroded and customers are evaluating more costly nonutility generation to meet future load growth. If some customers will pay a premium above BPA rates for power, how much load could BPA lose? Steps in the analysis are presented. RPSM is a system dynamics model used in energy policy studies since 1983. This study marked the first application for understanding effects of electric industry deregulation on BPA. RPSM was modified, potential nonutility supplies were forecast, and scenario simulations of acquisitions, loads and rates were performed for utilities in the region. Later, the study method was adapted for other uses at BPA.
