3. STUDY TARGETS To determine:
Required improvements in grid infrastructure
Integrating high shares of renewable energy source (RES) –based electricity
Maintaining security of supply
Impacts of:
Storage
Demand-side management (DSM)
Delayed phase-out of inflexible generation
Energy imports from North Africa
2/17

4. STUDY TARGETS Excluded: Distribution network
Economic power system optimisation and the economics of operating the power system
Required network upgrades and the cost of curtailed renewable energy are the only economic issues investigated
Further regulatory and policy implications
Voltage and dynamic issues
3/17

5. STUDY METHODS
Model the European electricity grid for the target year (2030 or 2050)
Estimate the energy utilisation characteristics applying hourly wind and solar data
Investigate the impact of different pathway scenarios
Optimise the grid to minimize curtailed renewable energy

6. 224 nodes across the Europe
Hourly data of a standard year in each node applied
Linear interpolation from 6-hourly data
Energynautics grid model (2010)

7. PATHWAY SCENARIOS
Three different levels (5%, 10% and 20%) of demand-side management
Inclusion of storage
Extended use of conventional power generation
European supergrid
High voltage direct current highways
Import from North Africa
Carbon capture and storage

9. STUDY RESULTS FOR 2030 Spain - France and Italy - Central Europe
20 GW
France
26 GW transfer capacity
North Sea offshore grid and surroundings
16 GW offshore
15 GW onshore
Support to Great Britain and Norway
15 GW
Balkans and Eastern Europe
40 GW transfer capacity
Nordic countries
10 GW transfer capacity
8/17

10. STUDY RESULTS FOR 2030 Storage inclusion Two different strategies
Large compressed air or pumped hydro storages
Large-scale electric vehicle distribution
Reduces offshore wind curtailment
High costs compared to grid upgrades
9/17

11. STUDY RESULTS FOR 2030 Curtailed energy
The role of DSM and storage seems to increase when increasing RES share (2050)
10/17

12. STUDY RESULTS FOR 2030
11/17

13. NORTH SEA OFFSHORE GRID
65 GW estimated to be available for harvesting
Large grid improvements required to reduce curtailment
HVDC (High voltage direct current) grid
More than 20 GW grid enforcements required
12/17

14. STUDY RESULTS FOR 2050 Regional scenario North Africa import scenario
Increased renewable energy production in Europe
High generation capacity increase costs
North Africa import scenario
60 GW import from North Africa via Spain and Italy
High grid investment costs

15. STUDY RESULTS FOR 2050
14/17

16. CONCLUSIONS Large grid upgrades required
Especially from North Sea and Southern Europe to the load centers in Central Europe
To ensure curtailment reductions (North Sea)
HVDC supergrid
Little impact from DSM and storage inclusion
But:
Reduce curtailment
Increased impact according to increased RES share
