Cyber Security Services for HVDC you can count on

Cyber threats are increasing with serious consequences for companies and communities worldwide. Critical infrastructure, such as power transmission systems, is increasingly becoming the main focus.

Today, IT systems are the foundation of critical processes for most companies. This leads to significantly increased risks of being attacked by hackers or viruses, and patching software weaknesses is not a onetime task but an ongoing endeavor throughout the system’s lifetime. For these reasons, Siemens Energy has developed a comprehensive cyber security service portfolio for HVDC to support you.

Basslink

Tasmania

HVDC system

The power of co-creation : Bringing energy transmission systems into the cloud

Digitalizing power transmission, they knew, would be a game changer for the industry.
But to make sure transmission system operators receive exactly the kind of added value which cloud connectivity and smart data analytics could bring to the business, Siemens Energy decided the customer should be an integral partner in the development process of a new digital service.
When the work began to bring the undersea Basslink Interconnector between Tasmania and mainland Australia into the Information Age, project lead Bernd Koppenhoefer, a specialist in digitalization and digital services for Siemens Energy, was at his apartment some 16,500 kilometers away in Nuremberg, Germany.
