Netherlands, Amsterdam: DNV conducted an extensive power failure investigation after an incident in an HV substation, and the summary is now publicly available.
The investigation was commissioned by the Dutch national electricity transmission system operator TenneT after the incident that occurred at the 150 kV Dronten Olsterpad substation in Flevoland on 2 September 2022. The incident caused by a prolonged short circuit led to arcing and overheating the feeding overhead transmission lines.
Overall, DNV concluded that the incident is considered an extraordinary situation and provided recommendations that would help enhance safety procedures and their application. The full report summary is available on TenneT’s website.
Although no people were injured, the incident had wide-ranging consequences –a power outage in the region, a temporary closure of the A6 motorway and the N309 regional road and a long-lasting interruption of train traffic on the Hanzelijn railway track between Dronten and Lelystad.
“For many decades, DNV has built comprehensive expertise, covering the complete range of power components and power systems, and is a respected, fully independent reference in the forensics of energy systems. As stated in our purpose to “Safeguard life, property and the environment”, safety is at the core of our commitment to the energy industry, which we continue to help be ever more secure and efficient,” declared Prajeev Rasiah, Executive Vice President for Energy Systems, Northern Europe at DNV.
