System Integration of Wind Power – Experiences from Denmark

Integration of variable renewables into the grid is sometimes and misleadingly presented as an invincible task. The Danish case proves this wrong with around 30% wind in the power supply – planning for 50% in 2020.

Long-term planning

In Denmark, long-term planning has ensured timely and relevant investments in the power grid in parallel with wind power deployment.


Strong interconnectors to a wider grid area allow electricity to be easily transferred from one area to another and provide flexibility and security of supply.

The role of the power exchange

A well-functioning market based on a power exchange ensures a transparent and cost-efficient transfer of power, and provides power producers with clear incentives to adapt production to the market signals.

Independent Transmission System Operator

Unbundling of generation and transmission creates a level playing field for all power producers. A strong and independent Transmission System Operator has proved to be very operational for a successful system integration of wind power.


The policy tools and measures are not unique to Denmark. The tools and measures may be applied by all countries, when adjusted to specific national circumstances.
