EnergyPLAN (computer model)

The EnergyPLAN model is a computer model designed for energy systems analysis. It is a deterministic model which optimises the operation of a given energy system on the basis of inputs and outputs defined by the user. The main purpose of the model is to assist the design of national or regional energy planning strategies on the basis of technical and economic analyses of the consequences of implementing different energy systems and investments. The model encompasses the whole national or regional energy system including heat and electricity supplies as well as the transport and industrial sectors.
The model is a deterministic input/output model. General inputs are demands, renewable energy sources, energy station capacities, costs and a number of optional different regulation strategies emphasising import/export and excess electricity production. Outputs are energy balances and resulting annual productions, fuel consumption, import/export of electricity, and total costs including income from the exchange of electricity.
