Satellite Outage Knocks Out Thousands of Enercon’s Wind Turbines

Germany’s Enercon on Monday said a “massive disruption” of satellite connections in Europe was affecting the operations of 5,800 wind turbines in central Europe. MarketScreener reports: It said the satellite connections stopped working on Thursday, knocking out remote monitoring and control of the wind turbines, which have a total capacity of 11 gigawatt (GW). “The exact cause of the disruption is not yet known. The communication services failed almost simultaneously with the start of the Russian invasion of Ukraine,” Enercon said in a statement.

Enercon has informed Germany’s cybersecurity watchdog BSI and is working with the relevant providers of the satellite communication networks to resolve the disruption, which it said affected around 30,000 satellite terminals used by companies and organisations from various sectors across Europe. “However, no effects on power grid stability are currently expected due to redundant communication capabilities of the responsible grid operators. Further investigations into the cause are being carried out by the company concerned in close exchange with the responsible authorities,” BSI said. There was no risk to the turbines as they continued to operate on “auto mode,” the company said. The report also notes that Viasat was “investigating a suspected cyberattack that caused a partial outage in its residential broadband services in Ukraine and other European countries”
