Invenergy and an American Electric Power (AEP) subsidiary have begun commercial operations at the 100MW Mega Solar Array in Nevada that will supply up to 90% of MGM Resorts’ daytime power needs at its 13 Las Vegas Strip properties.

AEP Renewables owns 75% of the project sited in the desert north of Las Vegas with 25% held by developer Invenergy, which will provide operations and maintenance and balance of plant services.

MGM Resorts International is purchasing all the power over the initial 20 years from the facility which is projected to have a 35-year operating life. Financial terms were not made public.

“Invenergy is a leading partner to companies like MGM Resorts who are increasingly focused on sustainability, and we commend the company’s dedication to investing in clean energy to power its operations,” said Ted Romaine, senior vice president of origination, at Invenergy.

MGM Resorts claims the facility in the “largest directly sourced renewable energy project in the worldwide hospitality industry.”
