Integration of renewable energy

The Danish government has set a goal that, in 2025, half of the Danish electricity consumption must be covered by renewable energy (particularly from wind power). This requires a more flexible and intelligent power system that can handle the fluctuating generation from wind turbines. Today, wind power makes up 21% of our electricity consumption. At the end of 2008, there were 5,101 wind turbines with a total capacity of 3,163 MW.

The integration of renewable energy into the energy system must be flexible and economic. Effective integrated planning of the electricity, gas, heat and transport sectors is important to meet this goal. Energinet.dk has identified a number of means of integrating wind power into the power system and integrating electricity from renewable energy sources into other sectors.

Integration of wind power into the power system:
• International connections
• Demand response/production
• Electricity storage
• Negative spot prices on the electricity market
• Geographical spread of offshore wind farms
• Disconnection of wind turbines

Integration of RE electricity into other sectors:
• Electricity for transport
• Electric vehicles
• Hybrid cars
• Hydrogen/fuel-cell vehicles
• Electricity for heating
• Heat pumps
• Electric boilers
• Micro CHP
