Vestas Wind Systems A/S, one of the world’s biggest wind turbine makers, said it has shut down IT systems across multiple business units and locations to deal with a cyber security incident. The incident occurred Nov. 19 and the company is working on recovering its systems, according to a statement from Vestas on Saturday. The shutdown may affect “customers, employees and other stakeholders,” the Aarhus, Denmark-based company said.
On the manufacturing side, it’s too early to say if they will be impacted, but some of the IT systems are used at our factories,” Anders Riis, vice president of communications, said by phone. The incident comes as Vestas and other wind turbine manufacturers struggle with rising commodities prices and supply-chain disruptions. The company — a bellwether for the wider industry — earlier this month cut its profit outlook for the year as higher steel prices boost production costs.
While the cyber security issue may affect production, so far it hasn’t impacted turbines already being operated by Vestas customers, nor the company’s ability to service those machines.
