If the power bill presently is in your name at the home that your mother has, you need to immediately contact the utility company via telephone about the situation and confirm such in a written letter that you want the bill out of your name for the simple fact that you are no longer residing in the unit.As to having the bill paid off, I suggest that you consult with your mother as to getting the bill paid down if you do not owe on it. The longer it remains unpaid, the worse your credit rating will become. You can ask the utility company to transfer the bill to your mother, however the chances for such seem remote based upon my experience in such matters.
