We've heard from people this morning saying they are receiving calls from someone claiming to be with Rochester Public Utilities.   The person on the phone tells them they have 30 minutes to pay their bill or their power will be shut off.   If you receive a call like this please beware that it is a scam.  Do NOT give out your credit card information.  If you are uncertain about the status of your bill you should hang up and call RPU directly. Their number is 507-280-1500
