MENA-EDS is a large-scale energy demand and supply model that simulates the formation of prices in energy markets, estimates the quantities demanded and supplied by the main energy system actors in an exhaustive manner, and incorporates energy related CO2 emissions, environmentally oriented policy instruments and emission abatement technologies. The model is designed for medium-term and long-term projections and produces analytical quantitative results in the form of detailed energy balances for each country.
