MGM Resorts International – in partnership with NRG Renew, the nation’s largest solar energy developer – installed a 20-acre, 6.4MW solar photovoltaic array on the rooftop the Mandalay Bay Convention Center in 2014. The project is but one way MGM Resorts demonstrates its dedication to environmental sustainability. In its first year of operation, the solar array offset the peak electricity demands of the property by as much as 20 percent. That’s enough energy to power 1,000 average-sized homes for a year.
