Case Study: Great River Energy

Offering reliable utility services with Cisco IoT

Great River Energy (GRE) is the second largest electric power supplier in Minnesota. When the company needed to replace aging equipment on a mass scale without disrupting service, it turned to Cisco IoT-enabled routers and switches. Cisco's hardware ensures always-on connectivity, increasing operational efficiency and improving the customer experience.



  • Replace aging equipment on a mass scale without disrupting service.
  • Provide electric service to 28 co-ops serving 700,000 families, farms, and businesses.
  • Address extreme climates across 56,000 square miles of Minnesota, North Dakota, and Wisconsin.


  • Deployed nearly 1,000 Cisco routers and switches, enabling GRE to temporarily shut down a third of its network.
  • Crews operated solely on LTE while upgrading equipment.
  • Cisco switches deliver superior communications services to industrial applications in the field.

What they're saying

During a state-wide systems upgrade, having backup LTE was key. In one month alone, we gained an additional 10,000 hours of availability system-wide while electrical gear was being replaced.
