ABSTRACT
This chapter explores a systematic method devised to translate national energy price projections by fuel type and sector into regional and state-level prices. It describes the methodological premise and basic design features of Argonne Regional Energy Price Simulator (AREPS). Detailed price projections were needed as input to energy models representing each fuel-consuming sector. The means to disaggregate the projected fuel price trends to the regional and state level is incorporated in the second aspect of the methodological premise. A number of procedures were investigated; most were dismissed as impractical or infeasible, given the study's constraints. The AREPS system was developed as a computer model that systematically produces price projections at the regional level by fuel type and end-use sector. Regional fuel price projections are produced in AREPS by applying a generic regionalization algorithm.
