The tipping point in getting this measure on the ballot may have been NV Energy's biggest customers, who have tried to weaken the company's dominance in Nevada. Casinos MGM Grand and Wynn Resorts agreed to pay more than $100 million in exit fees between them to leave NV Energy's service in order to procure power on the open market. In July, data storage company Switch sued NV Energy and the Public Utilities Commission ( PUC ) for not allowing it to do the same and shop around for more favorable energy rates.
