Ludwigsburg-Kornwestheim municipal utilities

Creating transparency | Mastering change

North of Stuttgart, Stadtwerke Ludwigsburg-Kornwestheim (SWLB) is a full-service provider of electricity, gas, water, district heating, fiber optics, and energy-related services with 440 employees. Like many other municipal utilities, SWLB is anticipating changes to its distribution networks. After many wallbox applications last year, interest in heat pumps is currently on the rise. PV expansion and thus feed-in are also continuing to increase. This presented the grid operator with the challenge of making these changes visible in the low-voltage grid using data. The goal of Stadtwerke Ludwigsburg-Kornwestheim's digitalization strategy is therefore to ensure grid security in the low-voltage range through transparency. With SMIGHT Grid2, they found a solution that was quickly implemented and continuously provides them with data from the grid as a sound basis for planning and decision-making. 

Measurement data show
unexpected phenomena

Thanks to the SMIGHT solution, interesting insights were quickly gained. These show that theory and practice do not match. Although the station was classified as non-critical, there were irregular and sporadic power peaks that significantly exceeded 200 amps. One thing is certain: without continuous measurements, this phenomenon would probably have remained undetected.

Outlook & Conclusion

When Ludwigsburg-Kornwestheim municipal utilities began their digitization project in 2020, they feared many hurdles, complexities, costs, and an enormous amount of time.

Many things that were originally planned were discarded, changed, or rewritten. What remained was a simple and quick-to-implement solution.

With SMIGHT Grid2, the municipal utility company is always informed about the load on the grid and can detect changes at an early stage.

Since October, the municipal utility company has been in the process of equipping additional stations with sensors until the beginning of next year. By the beginning of 2023, 100 stations are to be equipped with sensors. And for 2024, the municipal utility company is already planning to expand another 100 network stations.
