Multi-Scenario, Spatially-Detailed Utility Steam Coal Forecasting for the Ohio River Navigation System

The Corps of Engineers, over many years, has pursued continual refinement in the development of the waterway traffic forecasts used in project economic analyses.  The multi-scenario spatial utility steam coal forecasting described in this paper, which is based on the work of Hill & Associates, Inc. (H&A), represents a substantial refinement over previous forecasting efforts.

H&A prepares 20-year steam coal forecasts based on the interaction of two major linear programming models, the National Power Model (NPM) and the Utility Fuel Economics Model (UFEM).  The NPM is a utility industry model that dispatches all electric generating plants in the U.S. (both coal and non-coal), producing forecasts of generation by fuel type within a context of transmission and environmental constraints.   The UFEM makes use of highly-detailed coal supply data (for approximately 98 coal types) to allocate fuels among plants and units.  These two models developed forecasts of coal demand, by type of coal, for electric generation, which were then “mapped” to the waterway.   

H&A prepared separate forecast scenarios based on three alternative environmental regulatory futures.  The first of these represents a continuation of existing law, which in this case is the National Ambient Air Quality Standards.  This scenario is referred to as the NAQ scenario.  The second H&A scenario (referred to as the BUS scenario) reflects implementation of the administration’s Clear Skies Initiative.  The final H&A scenario is implementation of the Clear Skies Initiative without the proposal’s severe mercury restrictions.  This scenario is referred to as the BNH scenario.
