The output means the project will be able to power 65 million square feet of buildings and more than 36,000 rooms for venues like the Bellagio, Mandalay Bay, MGM Grand and the Mirage.
The operator claims it is a “global leader in the battle against climate change” and has echoed this by rolling out the hospitality industry’s largest directly sourced renewable electricity project.
The array of solar panels is located in the desert north of Las Vegas, featuring 323,000 panels arranged across 640 acres.
The ‘Mega Solar Array project’ was developed with Invenergy, a privately held developer and operator of sustainable energy solutions; there is a 20-year Power Purchase Agreement in place.
MGM Resorts has a goal to reduce company emissions by 45% per square feet by 2025. By 2030, it hopes to reduce Greenhouse Gas emissions and source 100% renewable electricity in the US and 80% worldwide.
Bill Hornbuckle, MGM Resorts CEO and President, said: "With MGM Resorts' significant scale and resources, we're positioned to make a meaningful difference in the fight against climate change, and we recognise our responsibility to build a more environmentally sustainable future.
"Today we're marking a significant step forward in our environmental sustainability initiatives in Las Vegas, and our long-term vision to protect the planet and achieve an enduring, positive impact in our communities worldwide."
Nevada Governor, Steve Sisolak, added: "MGM Resorts has long been Nevada's largest private employer and has shown a clear commitment to using their size and scale to lead on important issues like climate change, renewable energy and sustainability.
“This solar array is among the most significant steps our industry has taken in terms of tackling climate change and promoting renewable energy. Powering so much of the Strip with clean, renewable energy sends a powerful message about Nevada's role as a national leader in renewable energy and our commitment to fighting climate change."
