Models to Estimate Energy Requirements for Iron and Steel Industry: Application Case for Electric Steelworks

Nowadays the price of electricity depends on many factors; the introduction of renewable energy sources has changed the basics of electricity production and the determination of energy price. Iron and steel industries have the necessity to forecast the power amount they are going to spend: today production planning is performed without taking into account that the difference in electricity price between night and day can overcome 500%. The aim of this work is to create a model able to estimate energy requirements for iron and steel industry; the model correctness is assessed, for both energy and power analysis, by comparison with real data. The provisional planning tool is employed to provide data to a computer platform able to assess, on the basis of required energy, the best market on which power can be purchased in view of a money saving for the Company.
