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).
Grid losses inevitably occur during power transmission and result from the difference between energy feed-in and withdrawal. They can occur, for example, in the form of ‘corona losses’ (electrical discharge with a luminous effect) or as heat losses in conductors or transformers.
Grid losses depend, among other things, on the current, the voltage, but also on the distance electricity has to be transported. As more renewable electricity is fed into the grid these distances are increasing, as wind and solar electricity is often generated in remote areas, far from where most people consume it.
Transporting electricity a long way can cause larger grid losses compared to smaller quantities of electricity, or when transporting it over a smaller distance.
Grid losses contribute to more than 90% of our CO2 footprint. We are increasingly working to reduce our grid losses while at the same time optimizing our carbon footprint.
