“The world needs 100% renewable power by 2050. Electricity grids are the enablers of the energy transition”
Supply driven system
The energy system was demand driven, when demand increases, more electricity is produced. Now it moves to a supply driven system, when there is a lot of electricity production demand should increase (and vice versa). This should be done whilst still continuously and perfectly matching demand and supply just as before.
Managing grid congestion
The grid was originally not designed for a doubling of electricity demand and decentralized electricity production. This causes congestion and wear on grid components.
Getting the work done
Upgrading and expanding the electricity grid requires work. A lot of work. This work needs to be carried out whilst at the same time the number of skilled technical personnel is becoming even more scarce.
