RES Integration
1. Large-scale integration entirely feasible
2030:
• “missing links”
• offshore wind grids
• first step onshore
supergrid
230 000 km
€ 74-98 bn
280 000 km
€ 150-170 bn
2050 regional scenario:
RES close to demand
2050 import scenario:
60GW import (North Africa)
500 000 km
€ 530-680 bn
3. Necessary grid upgrades

Overview: Grid investments of € 70-98 bn by 2030 and €
149-679 bn by 2050
1. Promote flexibility and a balanced regional spread
• Stable and differentiated renewables support
• Market design to reward flexibility
• Reward “capability” & system services
• Intra-day rescheduling to take into account
all generators
• Congestion charges to reflect inefficiencies
from inflexible generation
3. A truly European network & management
• EU-wide approach for best use of capacity
cross-border day-ahead & intra-day trading
exchange & accounting of reserve capacity
• Long-term perspective in grid planning
anticipate RE-developments
reflect climate objectives
• Financing tools to overcome bottlenecks
User/beneficiary pays
financial tools for strategic investments
4. Transparency and public acceptability
• Transparency of network data
• Respect environmental & public concerns
