The US Army has awarded a subsidiary of Duke Energy with a new contract to provide electric services at Fort Jackson in Columbia.
Under the 50 year contract, Dominion Privatisation South Carolina will purchase, operate and maintain the electric utility system for the US Army.
The contract is worth $142 million and will come in effect from April 2019.
Dominion will acquire the grid infrastructure and operations as part of the army’s move to upgrade on-base utility systems, by selling them to companies with expertise on how to maintain them.
With more than 52,000 acres of land, Fort Jackson is the Army's largest and most active training center with more than 36,000 potential soldiers attending basic training annually.
Robert M. Blue, executive vice president, Dominion Energy, said: "We have a long tradition of working with the military.
"Our company is consistently ranked among the top companies in the nation in helping veterans and their families find and keep jobs in the civilian workforce. This new contract to provide electric service gives us another layer of support we can directly provide to the men and women in the armed services."
The news follows Dominion investing more than $750 million in gas transmission and renewable energy growth projects in South Carolina since 2015 and it is in the process of receiving regulatory approvals in its proposed merger with Cayce, S.C.-based SCANA Corporation, which serves 1.1 million electric and gas customers in the Palmetto State.
