We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).
The energy transition and economic growth are demanding more and more capacity from the electricity grid. In sparsely populated areas, for example, there are many requests for solar parks. Data centers and market gardeners are also requesting additional transmission capacity. As a result, the maximum capacity is being reached. This leads to a shortage of transport capacity in the electricity network. We call this congestion.
With congestion management, we allocate the limited space on the electricity grid. We do this at times when the demand for electricity transmission is higher than what the grid can handle. Is this demand too high at any given time? If so, customers will temporarily use or supply less electricity. The space that becomes available is distributed among other users of the electricity grid. This creates more space on the electricity grid.
