Wind and solar power

Wind power

Wind power is an essential technology to the energy system’s transition to using larger shares of renewable energy and to the reduction of green house gasses. The developments in technology in recent years have meant that land wind power is able to compete with other types of production at market terms, and the costs of offshore wind power have been greatly reduced as well.  

Integration of wind power into the energy system has several challenges though, since production from wind power is as the wind blows. An optimal use of wind power therefore requires a good interaction between production and consumption.  

Important topics are design of wind turbines, flexibility in the energy system (other power plants and consumption), transmission lines, sector links, and energy storage. 

In recent years, Ea Energy Analyses has carried out studies of integration of wind power in both Denmark and Europe, but also globally, for instance in Vietnam, Mexico and China. As well as more technical analyses, we have carried out a number of projects with focus on policy strategies for the most efficient integration of wind power.
