Las Vegas Strip Hits 100% Daytime Solar Power

The Las Vegas Strip just proved that even the brightest lights in entertainment can run on sunshine.

MGM Resorts International announced it now powers 100% of its daytime electricity needs across its Las Vegas properties with solar energy. The casino and resort giant reached this milestone in December 2025 when its new Escape Solar and Storage Project came online in Lincoln County, Nevada.

The project delivers 115 megawatts of solar power plus a massive battery system that stores 400 megawatt-hours of energy. Combined with MGM's existing 100-megawatt Mega Solar Array, the company more than doubled its renewable electricity access in a single leap.

Here's what makes this different: the battery storage system captures excess solar energy during peak sunlight hours and releases it during evenings and cloudy periods. That means the clean energy keeps flowing even when the sun doesn't shine directly on the panels.

"We are accelerating progress toward our goal of using 100% renewable electricity domestically by 2030," said Bill Hornbuckle, MGM Resorts' CEO and President. The company signed a 25-year power purchase agreement in 2024 to make the vision reality.

MGM operates some of the largest resort complexes in the world, where energy costs represent a major expense. The solar projects aren't just good for the planet but lock in predictable energy costs for decades, protecting the company from price swings in traditional energy markets.

The Ripple Effect

This move sends ripples far beyond the Nevada desert. When major energy consumers like MGM Resorts commit to renewable power at this scale, they prove that sustainability and business success can work hand in hand.

The company has been building toward this moment since 2016. Its Mega Solar Array features 323,000 panels, while Mandalay Bay's convention center hosts 26,000 rooftop solar panels generating 8.3 megawatts. Even T-Mobile Arena gets a boost from a 100-kilowatt rooftop array, and MGM Springfield in Massachusetts runs partly on 3,456 solar panels.

The battery storage component might be the most exciting part. As solar technology advances, the ability to store and deploy clean energy on demand solves one of renewable power's biggest challenges: intermittency.

For an industry built on spectacle and 24/7 operations, reaching 100% daytime solar proves that scale and sustainability aren't opposites.

Las Vegas may be famous for never sleeping, but now it's showing the world how to wake up to a cleaner energy future.
