4 Workshop II - Integrated Modelling of Environment and Energy Policy TIMES_PT Structure, Inputs and Outputs, Information Sources

5 Workshop II - Integrated Modelling of Environment and Energy Policy Dynamic model of linear optimization, that configures the energy system in such way as to minimize the net total cost of the system, while satisfying a number of constrains of the demand TIMES Model Objective function – maximization of total surplus (the step function it allows the optimization through linear programming) Analyze the system behaviour over a certain period of time and assume that the energy markets are in perfect competition and the agents have a perfect knowledge of his evaluation Assume a linear behavior between the outputs and inputs (However, does not mean that production functions behave in a linear fashion)

6 Workshop II - Integrated Modelling of Environment and Energy Policy Objective Function (Minimization of Total System Costs) Discounted sum of the annual costs minus revenues: + Investment costs + Costs for sunk material during construction time + Variable costs + Fix operating and maintenance costs + Surveillance costs + Decommissioning costs + Taxes - Subsidies - Recuperation of sunk material - Salvage value NPV: net present value of the total costs ANNCOST: Total annual cost d: general discount rate REFYR: reference year for discounting YEARS: set of years for which there are costs (all years in the horizon + past years if costs have been defined for past investments + a number of years after the life time of the technology if some investment and dismantling cost are still being incurred, as well as the Salvage Value
