Critical WAN for power utilities

Build a converged network that supports all your critical applications

Nokia Critical WAN for Power Utilities lets you build a secure, reliable, and modern communications network that enhances control and monitoring. It provides the network components and expertise you need to:

  • Enable TDM migration while preserving the integrity of traditional SCADA and teleprotection systems
  • Support new Ethernet- and IP-based protection, SCADA, and video surveillance applications
  • Launch smart grid applications more easily and integrate renewables

Our solution helps you transition to a utility-grade converged IP/MPLS and packet optical network that’s ready for growing Ethernet and IP application traffic, digital substations, and evolving with IEC 61850 and cloud. It gives you the flexibility to carry IP/MPLS services over an optical or packet microwave transmission layer. And it supports traditional TDM and new IP/Ethernet traffic with the high availability and stringent latency required for applications such as teleprotection.

We customize our solution to address the business needs of the utilities industry. Read our whitepapers to learn about the use cases and applications we support:
