Regular remote monitoring of your solar or wind power system

To prevent the power grid from becoming overloaded, grid operators must be able to control solar and wind power plants as needed and, if necessary, reduce their output. This may be necessary, for example, when too much solar power is fed into the grid on a sunny afternoon.

The water traffic light has turned yellow!
SWK is calling for people to use water sparingly.

SWK’s water traffic light provides early warning of the status of the drinking water supply. It will turn yellow on 26 June! The flow from the Lauterspring spring, the groundwater and the water treatment process are not yet causing any problems. However, water consumption is currently at its annual peak, at 30,000 m³ per day. The ongoing heatwave is expected to lead to further peaks in consumption, which is why SWK is asking people to use drinking water sparingly.
