More than 8 Megawatts of Solar Now Supplies 6 Percent of DIA’s Total Electricity Needs

DENVER--(BUSINESS WIRE)-- Constellation Energy (NYSE: CEG) and Denver International Airport (DIA) today announced the completion of a 4.4-megawatt, ground-mounted solar power system. Constellation Energy built, owns and maintains the solar installation, and DIA will purchase the electricity produced by the system over a 20-year period. It is the third large-scale solar project for DIA, bringing the airport’s total amount of hosted solar power to more than 8 megawatts – the most solar generation at a commercial airport in the United States.

In honor of the solar project’s completion, a celebration and ribbon-cutting were held today at DIA. Business and community leaders, as well as representatives from state and local government were on hand for the event, including Colorado Gov. John Hickenlooper, former Colorado Gov. Bill Ritter and Denver Mayor Michael Hancock.

“With the addition of this solar facility, Denver International Airport’s three solar array systems now produce approximately six percent of the airport’s total power requirements,” said Kim Day, aviation manager for DIA. “We support alternative energy applications at DIA because these projects are good for the environment while positively impacting our bottom line; they are financially sustainable. This airport was built with a goal of being green, and with this additional solar array, Denver International Airport now has one of the largest solar installations in North America.”

The system is expected to supply approximately 7,000 megawatt-hours of electricity to DIA each year, utilizing approximately 19,000 Yingli Solar photovoltaic panels. Generating the same amount of electricity using non-renewable sources would result in the release of more than 5,000 metric tons of carbon dioxide, according to U.S. Environmental Protection Agency data.

'Constellation Energy congratulates DIA for its continued commitment to clean energy,” said Michael D. Smith, senior vice president of green initiatives for Constellation Energy’s retail business. “Thanks to the shared commitment of federal, state and local government, along with private business, more businesses are able to rely on solar power to achieve environmental goals and control electricity costs. Constellation Energy thanks the public and private partners who worked with us in bringing this newest solar installation online for DIA.”

Denver-based solar development firm Oak Leaf Energy Partners originally developed the project; its third at DIA. Oak Leaf has developed 27 commercial and utility scale solar projects in Colorado, totaling over 35 megawatts of production. Quanta Services (NYSE:PWR) Intermountain Electric, which installed and manages DIA’s 2 MW and 1.6 MW solar facilities, installed the 4.4 MW project. Yingli Green Energy (NYSE: YGE) supplied the photovoltaic panels for the project.

Constellation Energy currently owns and operates approximately 95 megawatts of solar installations that have been completed or are under construction for customers throughout the United States. By structuring its solar projects as power purchase agreements, Constellation Energy requires no upfront capital from its customers and is able to provide power at a fixed cost that is less than projected market rates.

Commercial customers, universities, school systems, hospitals and government agencies interested in on-site solar installations of 1 megawatt or larger may contact Constellation Energy at or 1-877-427-2005.
