Constellation Energy and Denver International Airport (DIA) have completed a 4.4 MW, 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 MW, making it the biggest installed solar capacity at a commercial airport in the US.

DIA’s three solar array systems now produce around 6% of the airport’s total power requirements. The system is expected to supply approximately 7000 MWh 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 5000 tonnes of carbon dioxide, according to US Environmental Protection Agency data.

Constellation Energy structures its solar projects as power purchase agreements and currently owns and operates approximately 95 MW of solar installations either completed or under construction in the US.
