Case Study: Puget Sound Energy (PSE) achieves narrowband-compliant, scalable 75-position dispatch communications with Zetron's ACOM

75-position Zetron System Controls Operations at Puget Sound Energy

Puget Sound Energy (PSE), the utility serving more than 1 million electric and 750,000 gas customers across a 6,000‑square‑mile area in western Washington, needed to modernize its dispatch communications and comply with the FCC narrowbanding mandate. PSE selected Zetron’s ACOM console system (integrated with Tait Communications’ MPT 1327 trunked radio network) to replace legacy consoles and support its five centralized service groups for both electric and gas operations.

Zetron delivered two fully redundant ACOM systems with 75 console positions and deployed the solution in four phases—main center, backup center, 13 remote sites across nine locations, and final gas consoles—integrating with the new MPT 1327 infrastructure. The project met narrowbanding requirements, was completed on time and on budget, enabled immediate dispatcher adoption by mirroring existing screens, and provided measurable improvements in capacity and resilience (75 positions, 13 remotes) plus modular expansion, phone integration and remote command‑and‑control capabilities for future growth.
