The energy system – shift of paradigm
Present
Future
2011 – 25 % wind power in the electricity supply 2025 – 50 % RES – most wind power - equals 18 TWh wind power a year for Denmark But 50 % wind power is just a step stone – The Danish goal is non-carbon energy supply 2050 – 100 % RES in the energy supply – calls for electrification The high penetration of wind power calls for balancing and storage facilities The non-carbon future calls for coherent solutions electricity and gas partnership

Demand
Wind power covers the entire demand for electricity
In the future wind power might exceed demand
in 200 hours (West DK)
in more than 1,000 hours
Effective Wind power integration using:
Robust Transmission grid – with strong interconnectors Coherent energy system with high flexibility Intelligent control using Smart Grid applications
Energinet.dk strong prioritizing for 2025 Production
Means and solutions
+ 50% ? 50% Wind
+
Robust transmission grid, strong interconnectors and market integration
Flexibility in demand and production – cooperation with the heat- and transportation sector Smart Grid for efficient control and market based regulation of the power system – integrating of all local DER many based on gas
Smart Grid is the future
Smart Grid – puzzle to the future RES electricity system
CHP and gas for balancing the power system CO2 neutral Input resources Municipal waste Biomass Solar heat Geothermic heat Agricultural waste The Gas system Biogas Biogas – upgrade Thermal gasification RE-Gas Hydrogen
Heat system RE-Heat District heat CHP - flexibility Poly Generation Bio fuels High value Storable
Electricity grid Grid connection Marked participation Prosumer facility Ancillary services Fast regulation
2025 Strategic goals for the coherent energy Wind power as the major non-carbon RES supply - Calls for other sources of flexible and regulation power
Existing power plants with fossil fuels (coal) are closing down - The electricity grid need ancillary services from CHP units
Surplus of electricity in 900 – 1.200 hours a year - Calls for new consumption – Heat and Transportation (EV)
No wind production in many hours a year - Calls for strong interconnectors to neighboring countries
Intelligent use of Biomass – biogas and other bio resources - Bio resources must be utilized with maximum benefit - Electricity production - District heat production - Storable Bio fuel and RE-Gas
CHP units with Poly Generation is the future

Key messages; Utilization of Electricity and gas cooperation Competitive peak-load capacity from RE-Gas conversion- Turbines, FC or CC Will contribute to the integration of fluctuating RES – Wind power Optimal use of bio resources Substantial storage capacity in the gas sector at low costs
The future is already tomorrow – in Denmark The Climate agenda is unchanged -
The EU and Denmark will reach ambitious goals by 2020
30 % RES in the energy system ≈ 50 % RES electricity in Denmark 2025 -
The Danish focus is primary on Wind power and Biomass
50 % RES from electricity is just a step stone -
Denmark is aiming at reaching 100 % RES by 2050
Intelligent power system is one of the corner stones -
Electricity as the primary energy carrier – cooling, heat and transport
-
Strong Interconnectors and Market integration on European scale
-
Smart Grid allows integration of mutual RES
-
Gas fired CHP units for fast reserves and ancillary services
-
RE-Gas production and large storage facilities for the gas system
Energinet.dk strategy:
The worlds best RES based power system by 2025 - step stone towards non-carbon energy system by 2050
