Creating transparency | mastering change

North of Stuttgart, Stadtwerke Ludwigsburg-Kornwestheim with its 440 employees is an all-round supplier of electricity, gas, water, district heating and fiber optics as well as energy-related services. Like many other municipal utilities, SWLB is also seeing changes coming to its distribution grids. After many wallbox applications last year, interest in heat pumps is currently on the rise. PV installations and thus feed-in are also continuing to increase. The grid operator was therefore faced with the challenge of making these changes visible by means of data in the low voltage. The aim of Stadtwerke Ludwigsburg-Kornwestheim's digitalization strategy is therefore to ensure grid security in the low voltage 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 – irregularly and selectively – current peaks that went well over 200 amperes. One thing is certain: without permanent measurements, this phenomenon would probably have remained undetected.

Outlook& Conclusion

Logo

Stadtwerke Ludwigsburg-Kornwestheim feared many hurdles, complexities, costs and an enormous amount of time when they started the digitalization project in 2020.

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 utilities are always informed about the load on the grid and can detect changes at an early stage.

Since October, Stadtwerke has been in the process of equipping more stations with sensors by the beginning of next year. By the beginning of 2023, 100 stations are to be equipped with sensors. And Stadtwerke is already planning the expansion of a further 100 grid stations for 2024.
