Industrial process models of electricity demand. Volume 4. The aluminum industry. Final report

The National Center for Analysis of Energy Systems at Brookhaven National Laboratory has developed a process model of the US aluminum industry. The model consists of the major process steps in the manufacture of milled and cast aluminum products and is designed to select modes of operation and energy consumption characteristics that minimize the cost of meeting projected demands for the industry's products. Domestic refineries and primary smelters are represented individually in the model. Industry structure in terms of plant ownership and allowed transfers of aluminum-bearing materials is explicitly modeled. With a growth in product demand of 4.2% per year, model results show a decline in electricity intensity of primary production.
