DONG Energy has developed advanced control systems that allow our power stations to rapidly adjust thermal energy production to the power output from our wind farms.

Increasing the share of renewable energy
Integrating wind power with the power grid
Advanced operating systems for ramping thermal energy production up or down

In Denmark renewable energy has first priority in the energy ranking system. Wind turbines generate power when the wind is blowing, and the power must be used as it is produced as it cannot be stored on a large scale.

Balancing production and demand
In order to use wind power as part of a reliable energy supply, power stations must be capable of ramping thermal energy production up or down in response to the power output from wind farms and overall power demand. Power stations must consequently be able to take over power generation during low wind periods or when demand exceeds the electricity generated by renewable energy sources.

Modernising power stations
Most of DONG Energy’s thermal power stations were built before wind power became widely used. They were originally designed to generate a steady and almost constant power output.

Over time we have consequently modernised our power stations and developed advanced operating systems that efficiently adjust the stations’ thermal energy production to the volume of wind-generated power. Some of our power stations can be ramped up from low to full load in only 15 minutes.
