Rotterdam’s waterfront is part of the area protected by Stedin’s self-healing solution.
Stedin dramatically cuts re-energizing time with self-healing network
The Dutch utility is protecting its customers with an innovative network solution from Schneider Electric
As one of the largest utilities in the Netherlands, Stedin bears a lot of responsibility. Over 2 million customers depend on it for electricity, including government offi ces, major fi nancial and industrial customers, and the Port of Rotterdam, Europe’s largest port.
Driven by the desire to better serve its customers, Stedin looked for a solution that would signifi cantly reduce the duration of potential power outages. The challenge was to come up with a high-quality, cost-effective means of quickly re-energizing the MV network in case of a fault.
“We needed more monitoring in our system and to combine that with the reduction of customer minutes lost, we came up with an idea to install a self-healing grid,” said Edward Coster, an expert in Stedin’s SM Management Department.

Overcoming the challenge After considering its options, Stedin turned to Schneider Electric™
. The two companies
already had a relationship, having worked together on various projects, and the Schneider Electric team was able to foresee and avoid a number of technical problems. What resulted from this partnership was a decentralized, underground self-healing network, the fi rst of its kind in Europe.
The self-healing solution is based on an existing product — the Easergy T200 Remote Terminal Unit — which could be deployed with only minor reconfi guration, signifi cantly simplifying the project and speeding up the return on the investment. In addition, thanks to the fl exibility of the Easergy T200, the solution is scalable and replicable in other locations.
30
seconds is the approximate time to re-energize the unaffected area in the self-healing network.
