Tutor Perini Lands $652M Grid Upgrade at Naval Base Guam
Scope includes underground feeders, four substation upgrades and grid-control improvements
U.S. Navy vessels are berthed at Naval Base Guam, where Tutor Perini has been awarded a $651.8-million contract to harden and modernize electrical infrastructure serving key military facilities.
Tutor Perini Corp. said June 11 it had been awarded a $651.8-million task order from Naval Facilities Engineering Systems Command Pacific to replace overhead electrical distribution feeders with underground systems at Naval Base Guam.
The project is intended to improve the resiliency and reliability of the base's power infrastructure by replacing primary and secondary overhead electrical distribution feeders with underground circuit conductors installed in concrete-encased duct banks. It also includes upgrades to substations, communications systems and grid-control equipment supporting electrical service at several Navy facilities on Guam.
Construction is expected to begin in April 2027 following a design phase scheduled to start in August. Substantial completion is targeted for June 2031. Tutor Perini will perform the work through a joint venture with its Guam-based subsidiary, Black Construction Corp., a longtime Guam contractor.

Electrical-system hardening projects have become a growing focus on the island because of Guam's exposure to severe weather, including typhoons.
By replacing overhead distribution infrastructure with underground systems and modernizing associated control, communications and protection equipment, the project is intended to reduce vulnerability to storm damage while improving power reliability for mission-critical facilities, according to the federal procurement.
Tutor Perini said the contract value will be added to its backlog during the second quarter of 2026.
