HMS Construction has completed many public infrastructure projects for various government facilities around the United States.

Castner Substation – FY13 AD Pkg

The scope of work for this project included 20MW of upgrades to the existing 46Kv substation.HMS was the turn-key subcontractor for the installation of 4-5MW transformers, switchgear, SF6 circuit breakers, air switches, metering equipment, and modifications to the existing steel support structure. Site work included concrete spill containment, transformer pads, underground duct banks, manholes, and primary cable installations.HMS also assisted with coordination between Hawaiian Electric and Base Facilities to minimize outages.

Kapolei Energy Storage Project-185MW/565MWh Tesla Megapack system

The Kapolei Energy Storage project, located on the industrial west side of Oahu, Hawaii, is a groundbreaking initiative aimed at replacing the state’s last coal power plant. This state-of-the- art facility features a 185MW/565MWh Tesla Megapack battery system, consisting of 158 Tesla Megapack 2 XL battery units. The system is designed for load shifting and fast-frequency response services, facilitating the transition from coal and oil to renewable energy sources such as solar and wind. Developed and operated by Plus Power, the Kapolei Energy Storage project represents a significant milestone in Hawaii’s commitment to achieving 100% green energy by 2045. It provides crucial grid services including fast frequency response, synthetic inertia, and black start capabilities, ensuring the stability and efficiency of the Hawaii Electric grid as the state continues to expand its renewable energy capacity

Fort Irwin Fiber Optic Outside Plant Network

This project was done as a sub to Science Applications International Corp. (SAIC). HMS installed over 350 miles of duct bank, vaults, and fiber optic cable, ranging from 12 counts to 432 counts, along with the termination shelters and end equipment. This installation was performed at Ft. Irwin, the Army National Training Center. The project enhanced training and communication capabilities at that installation. This contract was completed in 2008.
