NV Energy says phone scammers are posing as NV Energy employees, calling both home and business customers threatening to cut off power if their bill isn't paid. 

NV Energy says they do not call customers to demand immediate payment "for any reason." The utility says the scammers are also using phone numbers that appear to be connected to NV Energy. 

It says customers who may be at risk of having their power disconnected because of nonpayment will receive a 10-day notice on their NV Energy bill and 48-hour notice via U.S. Mail.  

If customers receive a call asking for an immediate payment, they should refuse and call local law enforcement or NV Energy if they have additional questions. Customers may also call NV Energy's customer service department in northern Nevada at 775-834-4444. 

The utility says NV Energy employees or contractors will show a badge and employee number when contacting customers in the field. Employees are never authorized to receive payment in the field.
