Measurements create
added value in the
low-voltage grid

Digitalizing grid operations is essential to the success of the energy transition. The data that our SMIGHT Grid solution obtains from the low-voltage grid helps to identify and understand typical load profile patterns. On this page you can find out how our customers are already using this data.

What you can do with data from the distribution grid:

SMIGHT Grid allows you to create transparency at low-voltage grid level. The data that we collect doesn’t end up in the archive, but is immediately processed, analyzed, and made available to you in graphic form. This gives you quick and easy insights into the load history of individual feeders and helps you to understand, for example, the specific impact of electric vehicle charging and PV feed-in. The behavior of new consumers such as heat pumps can also be viewed. You can identify anomalies and their frequency. Use these insights to digitalize your operations:

  • Base strategic grid planning on real-time data
  • Better prioritize the renewal of assets
  • Handle load management with precision
  • Process grid connection inquiries more quickly
  • Locate cable breaks and faults more quickly
  • Back up operational decisions with data

Application: Strategic grid planning at ED Netze


ED Netze, a grid operator in south-west Germany, wants to drive the energy and mobility transition and gear its grid planning towards this. To this end, it needs to know whether and where bottlenecks caused by charging points and PV systems will occur over the long term. That is why up to 20 percent of the 4,000 local transformer stations will be equipped with SMIGHT Grid sensor technology in a gradual rollout. ED Netze can use the measurements to produce accurate load profiles for each feeder. These make grid models and forecasts much more precise. As the loads are progressively ramped up, the models can be verified and continuously improved with the aid of live data.

The process of planning and carrying out the grid expansion measures is thus more efficient and precise. ED Netze can significantly optimize costs for the building measures and the renewal of operating resources. Furthermore, the timing for both aspects can be more accurately determined.

Application: Detecting cable breaks at Stuttgart Netze


Locating cable breaks in an intermeshed low-voltage grid is a challenge. They often remain undiscovered for long periods of time and only become noticeable when the second supply cable fails. Many consumers are then generally affected. To prevent this from happening, Stuttgart Netze uses more than 500 SMIGHT Grid sensors in local transformer stations and distribution cabinets.

The measurement data feeds an AI algorithm that can identify and locate cable breaks. The ability of the systems to be interlinked is important for integrating the measurement data into the AI tool. This can be done simply and reliably with SMIGHT Grid. Stuttgart Netze can now react more quickly to faults and thus guarantee continuous security of supply and a high level of customer satisfaction.
