    • Stedin turns to EcoStruxure™ to optimize a self-healing grid

    The Dutch utility protects its customers with EcoStruxure

    Dutch utility develops cost-effective way to prevent and recover from power outages

    Stedin is one of the largest utility companies in the Netherlands, with more than two million consumers and business customers relying on it for dependable electricity. In an effort to meet growing demand, Stedin aimed to find a better way to ensure power outages don’t hinder its customers.

    The challenge

    Stedin turned to Schneider Electric to create a decentralized, underground self-healing network, the first of its kind in Europe. The self-healing solution is based on an existing product — the Easergy T200 Remote Terminal Unit – which is both scalable and replacement for use in other locations.

    Once installed at the main MV substations in an open-loop network, Easergy T200 units establish peer-to-peer communication using a virtual private network. If a fault occurs within the network the control center is notified, with no need to wait for operator response.

    An EcoStruxure-based solution

    Instead, the Easergy T200 units leverage EcoStruxure to communicate with one another, identifying fault locations and causes, then isolating and repairing the problems.

    Now, in the case of an outage that might otherwise have lasted two hours, the system cuts the time of re-energizing the unaffected parts of the grid to under 30 seconds. This translates to greater power availability for important commercial customers, as well as vital government offices. 

    Also, by automatically isolating the affected area, it takes less time to find, diagnose, and fix the problem.

    “I believe that we have to serve our customers better and better, so we put the self-healing network — and also more intelligence — in our grid,” said Marko Kruithof, Grid Coordination Manager at Stedin.
