Bad Wildbad municipal utilities

Facing the future | Securing supply

The Bad Wildbad municipal utility company is also observing the increase in e-mobility in the state and discussing the challenges that network operators will face as a result of the energy, mobility, and heating transition. What remained unanswered until now was the question of actual network utilization and what impact an increasing number of electric vehicles, heat pumps, and PV systems will have. The impetus for the project came from a meeting with managing directors of other grid operators from Baden-Württemberg. During the exchange, Peter Buhl, managing director of Stadtwerke Bad Wildbad GmbH & Co. KG, learned about the SMIGHT solution and how other municipal utilities are already using it in their distribution grids.

PV feed-in
creates imbalance

The SMIGHT measurement data from the low voltage system is available to the grid operator in graphical form and can be accessed at any time via a secure web portal. This gives Stadtwerke Bad Wildbad a good overview of the status of its grid. And if, as in this example, the threshold and fuse values are exceeded due to excessive PV feed-in, employees can react quickly.

The data we receive from 15 selected transformer stations gives us greater security. We now have excellent insight into our network, can identify changes at an early stage, and respond accordingly.

Peter Buhl Managing director Stadtwerke Bad Wildbad

We don’t want to take any unnecessary risks and want to maintain the high level of supply security we have enjoyed to date. That’s why we are already using SMIGHT Grid at this early stage of the energy transition to digitize our grid and collect meaningful data.

Outlook & Conclusion

Stadtwerke Bad Wildbad

SMIGHT’s smart power grid sensors are now continuously collecting data in the local distribution grid of the spa town of Bad Wildbad. Fifteen of the 85 local grid stations are equipped with sensors. The measurements show that the load on the grid is currently still within the normal range. The municipal utilities can detect changes in the grid at an early stage and respond accordingly.
