For much of the history of the electric power industry, power generation plants were built by utilities, paid for by ratepayers and incorporated into the utility ratebase as a result of approvals from state regulators.
The past decade has witnessed the development of a large fleet of unregulated, merchant-power generation resources in the United States (see Figure 1). More than one-third of all generation no longer is owned under the traditional vertically integrated electric utility model,1 and these unregulated assets face various markets and a wide range of risks. The revenue expectations for these assets often are divided into two categories: energy and capacity. These concepts frequently are used without a precise definition.
