Project description

As one of the four transmission system operators in Germany, TransnetBW GmbH continuously optimizes its power grid in order to adapt it to changing requirements in a forward-looking manner. The energy transition poses new challenges, especially for energy transmission.

The answer to the flexible feed-in of different energy sources is an adaptable transmission grid. One component of such a flexible grid is weather-dependent overhead line operation. By collecting weather data, power transmission capacity can thus be adapted to the prevailing weather conditions.

To implement this, 270 weather stations will be installed on overhead line masts and 30 weather stations on masts in substations along the power lines. The weather data will then be evaluated centrally and show detailed utilization capacities.
