Casino giant MGM Resorts says it plans to leave NV Energy in the fall, while Wynn Resorts is leaving its options open to do the same.
The companies filed documents with the Public Utilities Commission of Nevada this week after months of back-and-forth with regulators.
Wynn, MGM and Las Vegas Sands filed applications last year to leave and seek other energy providers on the wholesale market. They fought back when regulators imposed hefty "exit fees" as a condition of their departure.
But MGM said Thursday it will pay the $87 million fee, which covers costs the utility company incurred expecting that MGM would stay on board.
Sands effectively ended its effort by missing a deadline, but a spokesman told the Las Vegas Sun it will remain active on energy issues.
