Killeen Regional Airport Deploys Solar

Killeen Regional Airport in Texas announced the successful completion of a solar-integrated covered parking project. 

In partnership with energy solutions provider Ameresco, the airport added the solar arrays to the short-term parking and rental lots along with an LED retrofit throughout the airport. 

The 1.2-MW project features a solar array serving the terminal, a solar array for the rental lot, and a solar array for the short-term parking lot. Additionally, it encompasses a comprehensive terminal lighting retrofit, replacing interior and exterior lights with energy-efficient and longer-lasting LEDs. A covered pedestrian walkway was also constructed to seamlessly connect the terminal to the rental lot.

“This is a day that we have looked forward to for many years,” Mike Wilson, Executive Director of Aviation for the City of Killeen, said in a statement. “The full project includes a complete LED retrofit of the entire airport campus. I am very proud of this project because not only will it decrease the airport’s operating budget by lowering our energy costs, but it will also provide a much-needed upgrade to the customer experience.”

The project was made possible through a competitive grant process with the Federal Aviation Administration (FAA) Airport Terminals Program (ATP). The final scope of the project amounted to over $7 million, with a grant award of $5 million. This investment is estimated to offset 68% of the airport's purchased electricity, showcasing a significant step toward energy efficiency and sustainability.
