Summary

The commission authorized GWA to solicit design‑build services for phases 1 and 2 of a SCADA control‑center project, an estimated $4.8 million procurement intended to centralize monitoring for roughly 420 remote sites and improve operational reliability and cybersecurity.

The Guam Public Utilities Commission authorized the Guam Waterworks Authority to solicit design‑build services to create a centralized SCADA (Supervisory Control and Data Acquisition) control center and to integrate existing site‑level systems in an initial two‑phase effort.

Legal counsel told commissioners the solicitation covers phases 1 and 2 of the project at an estimated $4,800,000, which triggers PUC review because individual contracts exceeding $1,000,000 require authorization. Counsel said GWA currently operates multiple, disparate SCADA hardware and software solutions across roughly 420 remote sites (wells, reservoirs, pump stations, valves and master meters) and lacks a centralized SCADA station.

GWA representatives, including Lisa Rojas and acting General Manager Thomas Cruz, said phase 1 would build a SCADA control center and phase 2 would integrate an existing site‑level SCADA center into the new central station. They emphasized operational benefits including improved training, simplified licensing and spare‑parts management and reduced cyber risk. GWA indicated the project would be funded in part with bond proceeds and that the procurement term contemplated an initial three‑year contract with two one‑year options.

Commissioners moved and approved authorization for GWA to issue the solicitation; the transcript records the motion, a second and an affirmative vote.

Next steps: GWA will issue the solicitation and respond to proposals; because bond funds are implicated the PUC’s authorization to solicit was required before issuing the request for proposals.
