Summary
Development and implementation of an enhanced modeling system for electricity market analysis is explained. The relevant geographic areas that must be used for accurate supply and demand modeling and analysis are defined. There is no national market for electricity in the United States. Surplus hydroelectric capacity from the Pacific Northwest cannot be made available in Florida. Any model of U.S. electricity consumer and producer interaction that does not differentiate by region would produce misleading results. The expected natural gas-dominated capacity expansion phase in electricity markets is described. Natural gas fired technologies provide the lowest busbar cost for many regions' intermediate and peaking dispatch roles. Environmental concerns over acid rain compliance due to the Clean Air Act Amendments of 1990 and proposed global warming stabilization measures favor natural gas fired technologies. The results of the enhanced modeling system are used to identify the size, timing, and composition of the expected capacity expansion. The study also examines the effects of this future capacity expansion on electricity prices.
