Denver International Airport’s (DIA) fourth solar array is now online, bringing the airport’s total solar generating capacity to 10 MW.
The Solar IV array is located on the north side of Colorado airport’s property, and is capable of generating up to 2 MW, or 3.1 million kilowatt-hours of solar electricity annually, the airport noted in a June 18 statement.
“DIA was designed to maximize sustainability, and we have embraced and expanded that legacy over the last 19 years,” said airport CEO Kim Day. “We continue to invest in initiatives that reduce our carbon footprint and preserve the natural assets of Colorado.”
The developer for the Solar IV project is Oak Leaf Energy Partners. The project cost of about $6m will be paid for by the owner, Denver Solar IV LLC. DIA will buy the electricity generated by the array over a 20-year period at a cost per kilowatt-hour that is less than the average cost DIA pays to Xcel Energy (NYSE: XEL) for electricity.
Some of the electricity generated by Solar IV will be used directly at DIA, while excess electricity will be sold to Xcel Energy’s grid. With the addition of Solar IV, DIA’s four solar arrays now have the capacity to generate 10 MW, or 16 million kilowatt-hours of electricity.
