A tornado tested one utility’s private wireless network. When the clouds cleared, communications built for the grid clearly demonstrated their value.
By itself, a private wireless communications tower is only infrastructure. Its real value is the traffic that moves across it: The dispatcher telling a crew where to go next. The telemetry showing operators what is happening across the grid. The voice connection to a line worker 40 feet in the air, working in darkness and dangerous conditions.
When a utility loses a tower, it does not simply lose coverage. It can lose visibility into its own system, the ability to coordinate its workforce, and precious time during restoration.
When a severe tornado outbreak swept across one utility’s service territory shortly after its broadband network was deployed, operators knew the communications system was facing a serious test: would it remain available while the storm passed, and could the utility continue relying on it to operate and restore power to impacted customers.
The answer was clear. Across the utility’s private broadband network, only two communications sites of their dozens were affected. At one, the disruption was little more than a blip as battery backup engaged and service continued. Even with another site temporarily offline, the utility retained the communications capability it needed to understand conditions across its system and to respond safely and efficiently.
Severe weather cannot be controlled. Utilities know that better than anyone.
What they can control is how their critical infrastructure is designed to withstand it. Private wireless broadband gives utilities the ability to engineer and operate communications around their own operational requirements. Sites can be hardened. Backup power can be designed for utility restoration scenarios. Redundancy can be built where the grid requires it. And, as risks and challenges evolve, the network can evolve with them.
Most importantly, the utility owns the path forward when conditions deteriorate. That ownership mattered during the storm. While the sky was still clearing, operators could see their system, identify damage, and direct crews where they were needed most. Communications remained an operational asset rather than another uncertainty to manage.
The impact extended far beyond network availability.
It meant smart grid devices could continue operating to help prevent customer outages. It meant more than 2,000 restoration personnel could be coordinated across a heavily impacted service territory to replace nearly 1,000 poles with 100 miles of damaged electric lines.
It meant restoration estimates could be based on real operational visibility rather than incomplete information. Those are not simply network statistics. These are grid outcomes that affect people's lives.
Public commercial wireless networks can face a very different challenge. Capacity is consumed by thousands of customers calling and texting to check on family and friends.
That is not a failure of commercial networks. It reflects what those networks are designed to do: serve everyone. Utility private broadband networks are designed for a different mission. They are engineered around the communications requirements of the electric grid, giving utilities greater control over coverage, resiliency, priority, restoration, and long-term network evolution.
When severe weather arrives, communications becomes part of the restoration system itself.
Because when the weather is at its worst, utilities need more than connectivity. They need communications they can see, control and depend on to restore service safely and quickly.
