The Mandalay Bay casino and convention center in Vegas is ginormous. MGM Resorts, who owns it, has installed 21,324 photovoltaic panels on twenty acres of convention center roof. Yes, twenty acres… The 6.4 MW system will provide 20% of power for the center, with an additional 2 MW coming when the convention center is expanded. Well done, MGM.
How big is Mandalay Bay? The main hotel is upscale. Delano, an even-more upscale hotel, is in a separate building. A super-upscale Four Seasons occupies five floors of the main hotel. The casino is 135,000 sq ft, The convention center is 1,000,000 sq ft. An events center has 12,000 seats. There are 30+ restaurants, shopping malls, multiple bars and other venues. Plus, Mandalay Bay connects to Luxor (semi-upscale) and Excalibur (low-end), which are also owned by MGM.
The project is being done in partnership with NRG Energy. Once it is complete, Mandalay Bay will buy from NRG the solar energy through a Power Purchase Agreement at prices below the peak rates on the traditional NV Energy electrical grid (Based in New Jersey, NRG is also a major partner in the Ivanpah solar plant that opened earlier this year near Primm, Nev.).
