While gamblers might be inside tugging on one-armed bandits or rolling the dice at craps MGM Resorts’ Mandalay Bay in Las Vegas made a smart bet by installing the US’s largest rooftop solar array. The 8.3 megawatt behemoth rooftop solar array consists of 26,000 photovoltaic panels and supplies 25 percent of the power required to run the whole Mandalay Bay Resort & Casino campus.
"The expansion of our rooftop solar installation at Mandalay Bay significantly advances our resort's commitment to being a leading sustainable destination for conferences and conventions. Utilizing energy produced from a renewable resource is a cornerstone of our comprehensive strategy of sustainable operations,” asserted Chuck Bowling President and COO of Mandalay Bay.
It’s actually a doubling down on the technology for the resort and casino complex. The first, 6.2 megawatt phase, of the system was completed in 2014. Both the new and older system are owned and operated by NRG Energy, which is supplying the power produced by the arrays to MGM under a 25-year power purchase agreement.
"MGM Resorts International has a long history of integrating environmentally responsible practices throughout our operations to help preserve the planet's limited resources," stated Cindy Ortega, senior vice president and chief sustainability officer of MGM Resorts International. "Our continued partnership with NRG is a source of pride and inspires our desire to continually implement innovative solutions that promote renewable energy.”
The new, 2.1 megawatt project consists of 4,644 Ten K Solar solar panels and uses 180 inverters. It also uses a non-penetrating roof tacking system with 3M’s Cool Mirror Film that the company said reflects specific light wavelengths for the photovoltaic cells allowing the panels to capture more light from the reflections.
"Companies like MGM Resorts are driving an evolution in America's energy mix as they seek cleaner sources of power that provide more certainty over energy costs," said Craig Cornelius, senior vice president of NRG Energy. "The solar array atop Mandalay Bay is stunning in its scope and functionality, and we're thrilled to have MGM as a partner."
Still don’t expect MGM to retain the title for too long. Already bigger rooftop solar projects are underway like the 16.4 megawatt rooftop solar project on Los Angeles warehouses that will cover 2 million square feet of space—a rooftop solar project that might be the biggest in the world when completed.Tweet
