Denver International Airport's (DIA) fourth solar power array is now operational, bringing the airport's total solar capacity to 10-MW.
The solar array is located on the north side of the property, and is capable of generating up to 2-MW, or 3.1 million kWh of solar electricity annually. In addition, the array has the capacity to offset an estimated 2,200 metric tons of greenhouse-gas emissions each year.
The developer for the $6 million project is Oak Leaf Energy Partners, and will be paid for by the owners, Denver Solar IV, LLC. DIA will buy the electricity generated under a 20-year power purchase agreement.
Some of the electricity generated by Solar IV will be used at DIA, while excess electricity will be sold to Xcel Energy's (NYSE: XEL) grid. The electricity that is used at the airport will power the Denver Fire Department's Aircraft Rescue and Fire Fighting (ARFF) Training Academy.
In 2008, DIA installed its first solar array. Solar II came online in 2009, followed by Solar III in 2011. The airport now has a total of 42,358 individual solar panels spread across 55 acres of solar fields.
