Officials have marked the completion of a solar energy farm that covers nearly 75 acres at Indianapolis International Airport.
The ceremony was held Friday at the site next to the Interstate 70 exit to the airport's passenger terminal.
Indianapolis Mayor Greg Ballard said the project was a sign of the city taking a national leadership role in promoting alternative energy.
The project's private developers are leasing the land from the airport and selling the electricity generated from the 44,000 panels to Indianapolis Power & Light Co.
IPL President Kelly Huntington said the airport solar farm will help the utility reach its goal of having wind and solar sources make up 10 percent of its electricity by 2017.
Additional land at the airport also could become a solar farm.
