Time to switch

In the energy sector, electric power grid operators need reliable, future-proof systems that can adapt to ongoing changes more than ever before. This is where digital technology plays a key role.

Digitalization ushers in a new day for the electric power industry around the world. The digital substation lies at the cornerstone of the evolving digital utility. It is the heart of an infrastructure that must be able to withstand the evergrowing amount of data that will be generated and consumed by digital substation equipment in the coming years. To achieve this, operators must streamline the information and data exchanges in the electrical grid and supporting communication networks.

The new rugged Ethernet switches from Siemens are key additions to the essential building blocks of a powerful industrial communication network in a digital substation.

Providing secured, real-time communication with large bandwidths and high system availability, these new products pave the way for utilities to deploy enhanced networking solutions for digital substations. With our solid expertise in the electric power industry we understand industrial network design for digital substations better than anyone else. Our network solutions shape up the future of digital substations. From design to implementation: Siemens experts are there every step of the way to make digitalization a reality for utilities worldwide.
