In a strategic move to bolster grid resilience and reduce storm-related outages, Ameren Illinois and Ameren Missouri are installing composite utility poles manufactured by Trident Industries at their Granite City facility. These fiber-reinforced polymer (FRP) poles, branded as TridentStrong™, are engineered to withstand extreme weather conditions while offering a safer and more efficient alternative to traditional wooden poles.

The initiative comes amid growing concerns over aging infrastructure and the increasing frequency of severe weather events. Unlike conventional wood poles, Trident’s composite poles are designed to bend without breaking, significantly reducing the risk of cascading failures during storms.

"By installing these stronger composite poles at key locations, Ameren is able to enhance reliability for our customers, especially when severe weather strikes," said Ben Lynch, director of distribution operating for Ameren Missouri. "This strategic approach helps minimize disruptions by limiting the scale of damage and making restoration much quicker.”

Ameren strategically installs composite poles every fifth pole, alternating with four wood poles, to storm-harden its power lines. Their multi-layer construction provides superior strength and flexibility, making them ideal for high-risk areas across Ameren’s service territory. Ameren has set more than 7,000 composite poles across its service territory.

“Ameren’s adoption of TridentStrong poles reflects a forward-thinking approach to grid modernization,” said Riley Adams, senior manager of electric programs for Ameren Illinois. “These poles are not only more durable but also easier to install and maintain, thanks to factory pre-drilled holes and internal ground wires that deter copper theft and simplify setup.”

The Granite City facility plays a pivotal role in this transformation. With manufacturing capabilities tailored to meet utility demands, Trident Industries ensures rapid deployment of poles in various profiles and diameters.

This partnership also aligns with broader industry trends. Creative Composites Group, which acquired Trident Industries in 2024, has been expanding its footprint to support utilities nationwide in their grid-hardening efforts.

As Ameren continues to invest in infrastructure upgrades, the use of composite poles marks a significant step toward a more resilient and sustainable energy future for communities across Illinois and Missouri.
