European Swiss TIMES Electricity Model

European Swiss TIMES Electricity Model (EUSTEM)

Model description

The European Swiss TIMES Electricity Model (EUSTEM) is a multiregional electricity model of Europe. The model was developed by the Energy Economics Group at PSI using the TIMES modelling framework – a least cost optimization framework, i.e. EUSTEM identifies least-cost combination of power plants and electricity generation mixes to satisfy exogenously given electricity demands. The model has long model horizon (2010-2070) with high intra-annual detail at seasonal and weekly levels to account for variations in electricity supply and demand at an hourly time resolutions. This high temporal resolution combines capacity expansion and ad-hoc dispatch in a single framework.

EUSTEM has 11 regions encompassing 20 of the 28 EU member states (plus Switzerland and Norway) (see Figure). It covers 90% of the total installed capacity and 95% of the total electricity generation of EU-28. Each of the regions are connected though an aggregated interconnectors, which enable electricity trade between regions based on long run marginal cost of electricity suppl. The model is calibrated to the 2010 electricity statistics by including all existing power plants aggregated by plant type and fuel mix; and a wide range of new and emerging electricity generation technologies. For each of the region, renewable energy resource potential and carbon capture and storage (CCS) potentials are implemented. All input data and assumptions are well documented (Pattupara, 2016).

The model can be used for a long term electricity supply scenarios analysis. The figure below shows electricity supply for Europe and electricity dispatch pattern for Germany on a Summer and winter week day in 2050.
