Reducing waste and conserving energy are both parts of MGM Resorts International’s strategic plan for environmental responsibility. Our design for the rooftop solar array at the Mandalay Bay Resort Conference and Convention Center creates a striking presence along the Las Vegas skyline and visible proof to both hotel guests and Las Vegas residents of MGM’s commitment to sustainability.

Designed for Fortune 500 company NRG Energy, the 21,325 module array provides a functional solution to the demands on the southern Nevada electrical grid. As one of the first utility-scale rooftop arrays ever designed, the project covers 11 acres of roof area and producing over 6,400 kW of clean energy. The array provides over 20 percent of the hotel and casino’s power demand by utilizing a state-of-the-art monitoring and control system. The project is estimated to displace approximately 6,300 metric tons of carbon dioxide, which is the equivalent of taking more than 1,300 cars off the road. The project won the Silver Award: Energy – Engineering Excellence from the American Council of Engineering Companies (ACEC) Washington. Our firm provided electrical and structural design services for the project.
