Power Systems of the Future
How does the Electricity System benefit from
Power-to-Gas Coupling?
The European energy transition
Production
SunPV
Wind
EU Goals 2050:
Power sector decarbonized.
2050: 80-95% CO2 reduction.
Challenges: Support schemes | renewables goals | national focus
TenneT at a glance (Gridmap)
8 x 700MW
• 700 MW AC
• Standardized
• Borssele
Alpha (NL)
2 GW the new standard?
• World first 2 GW platforms
• 700 MW AC 2 GW DC
• 525 kV cabling
• IJmuiden Ver wind area (NL)
Climate agreement in NL

SUN PV HYDROGEN
Increasing system dynamics
Generation of 2030 projected on historical actual weather
North Sea infrastructure Three main functions
• Connection of countries: price convergence
• Transmission of offshore wind energy
• Enhance system security and stability by allowing the
exchange of power
No consumption at sea
Impact of failures differs
• Cost of onshore failure 200 x cost of electricity not delivered
• Cost of offshore failure 1 x cost of electricity not delivered
Solution: the Wind Connector
The ‘wind-connector’: wind infrastructure and interconnector combined
in one function
