The model uses key inputs (baseline demand, renewable potentials, weather, existing capacities, political targets, and fuel prices) to optimize a least-cost, constrained energy system by minimizing the net present value of total system costs. It balances supply and demand across regions, years, and time steps while considering sector-coupling options, and outputs key parameters including primary energy demand, sectoral demands, technology investments, renewable generation, fossil-fuel phase-outs, and emissions.
