2 Outline 1. Basic modelling assumption Northern Europe scenario development 3. Simulation results 4. Transmission investment analysis 2

3 Modell development Objective: Develop a data model set for EMPS, which takes into account the hydro system characteristics in the Nordic as well as the thermal characteristics in continental Europe. The data model shall be suited to assess the (economic) outcome of the prospective integration of variable renewable energy sources in the Northern European power system. under development in: PhD in the project "Balance management in multination power markets" EU FP7 Twenties Transmitting wind Implementation of the investment analysis in EMPS 3

4 Geographic overview Denmark, Finland, Norway, Sweden, Belgium, Germany, the Netherlands, Great Britain

5 Basic assumptions 56 areas (including neighbouring countries) 8 corridors (including HVDCs) (39 busses for Norway / 3 busses for Sweden => Samnett /NVE dataset) 75 climatic years (temperature, hydro, wind, solar) Series simulation (34 sequences per week / 52 weeks per year) thermal power plants with start up costs (marginal production costs / start up costs based on fuel prices) Operational (spinning) reserve requirements District Heating Max. calculation time => 1.5 days in Version 9.3 (using CPLEX) (2.5 weeks in Version 8.4) 5

6 Fitted generation mixes (per country) ENTSO-E 21: EMPS 21: Differences due to load definition (transmission system load vs. total system load) 6

9 Future scenarios updates Generation portfolio: 11 GW increase in hydro generation capacity in Southern Norway (including pumping), small scale hydro in Norway and Sweden Adapted thermal capacity - commissioning and decommissioning of (individual) thermal power plants Constant fuel cost / CO 2 emission cost increased Increased WPP (up to 191 GW throughout the modelled area) Transmission capability: Internal (Norway west coast, Sweden north-south, Germany north-south) Cross-border (HVDCs subsea cables, AC interconnectors) North-Sea offshore grid in 23 (according to OffshoreGrid project) Consumption increase by 5-9

15 Power production Profitability of generation assets Thermal Significantly reduced operating hours => reduced income and profitability of thermal power plants => will thermal capacity be decommissioned? Hydro Reduced annual profitability from 18 /kw to about 135 /kw due to increased hydro generation capacity => is building new generation capacity profitable? 15
