Dallas-Fort Worth International Airport is planning to renovate the control room at its energy plant this year as it continues to celebrate its 50th anniversary.

“The Energy Plaza within the Central Utility Plant provides cooling and heating services to approximately 7,000,000 square feet of space including terminals, hotels, and other support facilities,” a DFW spokesperson said in an email to The Dallas Express. “The system provides heating and cooling to the terminal jet bridges and docked planes. It is also used to monitor and control other airport public utilities such as potable water and sewer.”

According to a state filing, the work includes demolition and renovation of existing space inside the control room, providing a “handicap accessible kitchen” and updating technology. With an estimated construction cost of $3.5 million, the project has an anticipated delivery date of November 15.

Meanwhile, the airport plans to begin a construction project by the end of the year involving the renovations of ramp and concourse levels, a baggage claim carousel, and modifications to ramp level spaces, as reported by The Dallas Express.

The airport has been working on other infrastructure projects, including the Terminal D South gates expansion, the High C gates renovation, the opening of its Integrated Operations Center, and upgrading runways and taxiways. The projects, spanning about 850,000 square feet of terminal space, will be completed in phases, with an anticipated delivery date of June 2026.

In March, the airport plans to replace 20 elevators it uses to move customers among its five terminals to improve its Skylink system, The Dallas Express reported.

DFW opened on January 13, 1974, becoming the second-largest airport by land size in the country and the second busiest in the world, according to its website.
