Hartsfield-Jackson Atlanta International Airport in the US will receive an investment of around $100m from Georgia Power and the Atlanta Airlines Terminal Company (AATC).

The invested amount will be used for the airport’s infrastructure, ensuring improved reliability with a resilient power system.

The investment will cover both the cost of the new power generator system and its installation.

Georgia Power will offer the infrastructure while AATC will pay for the provided back-up generation services.

Through this long-term investment, both firms will provide constant back-up power generation service to all terminals and concourses at the airport.

Georgia Power chairman and CEO Paul Bowers said: “We are dedicated to ensuring we provide safe, reliable energy for the long-term needs of Hartsfield-Jackson Atlanta International Airport as it continues to grow with our city and our state.

“We are working hand in hand with our partners at the Atlanta Airlines Terminal Company and the City of Atlanta to invest in the airport’s power infrastructure to help ensure the highest reliability for our customers today and their future growth.”

Georgia Power, in partnership with AATC, will run and maintain the generator systems, which will be supplied by PowerSecure.

The new power back-up system will be deployed over the next two years and will substitute the airport’s current back-up system.

AATC CEO Dr Kofi Smith said: “Atlanta Airlines Terminal Company, the City of Atlanta and Georgia Power have all been working together as one team to help ensure that our passengers who travel daily through Hartsfield-Jackson Atlanta International Airport continue to have a safe, world-class experience.

“Our long-term investment in the airport will help continue to position Atlanta at the forefront of commercial air travel serving passengers from our region, the country and across the globe.”

The investment was actualised through a three-way agreement in which the City of Atlanta recognised the joint plans of both firms to improve the airport’s utility infrastructure.

Hartsfield-Jackson Atlanta International Airport general manager John Selden said: “This investment will not only benefit the City of Atlanta for the long term but will also help ensure Hartsfield-Jackson Atlanta International Airport continues to serve passengers safely and reliably as the world’s busiest airport.”

In a separate development, Southwest Airlines has officially initiated flights out of Chicago’s O’Hare International Airport (ORD) in the US.

The airline has started nonstop flights to Baltimore, Phoenix, Dallas, Denver and Nashville.
