Energy Supply Model Message and Its Application to IIASA’s World Region V
The energy supply model MESSAGE (Model for Energy Supply Systems and Their General Environmental Impact) is a dynamic linear programming (DLP) model which minimizes total discounted costs of energy supply over a given time horizon. The main subject of the model is the balancing of demand for secondary energy and supply of primary energy resources via a menu of technologies. The most important model constraints reflect limits on the speed of buildup of technologies, the availability of indigenous and imported resources, and technological relationships. The model considers load regions for electricity demand, disaggregates resources into cost categories, and calculates environmental impacts of energy supply strategies. The model output is used to describe scenarios of energy supply. These scenarios account for the physical flows of energy between primary energy and end use; shadow prices of supply and demand constraints; and environmental impacts of energy supply paths, expressed as emissions and concentrations of pollutants.
