Regional transportation options and costs of transmitting present and future energy sources influence selective choices. A multi-regional model permits energy policies to be addressed at a regional level of disaggregation. A multi-regional linear programming model of the nation's energy system is currently being developed at the National Center for Analysis of Energy Systems, Brookhaven National Lab. The two essential components providing the analytical power to such a model are: (1) an adequate representation of the regional cost structure of energy transportation, and (2) region-specific resource-supply functions. In support of these modeling activities, the Logistics Management Institute (LMI) has derived the volumes and transportation unit costs of coal, crude oil and natural gas shipped between the Nation's Census Regions. LMI has also provided regional supply functions in these same resources. The volumes and costs are based upon the 1985 Reference Case of the Federal Energy Administration's Project Independence Evaluation System (PIES) Model. Results in terms of volumes and unit costs of fossil fuels moved between Census Regions are shown in matrices. Coal movements are covered in Chapter I, crude oil in Chapter II, and natural gas in Chapter III. Coal supply curves are presented in Appendix A, oil supply curves in Appendix B, and natural gas supply curves in Appendix C. (MCW).
