just get a copy of the old tnb bill (or from neighbour) and it is stated in the bill which tnb office to go. just fill in a form and pay rm20 stamp duty to change account to your name. but they will ask u to settle the old bills b4 change to new owner. i dun think u can create a new account since it is an old prop. (ok for new prop or rumah setinggan ). otherwise, everyone can go to change account and owe tnb thousands of arrear. eg husband change name to wife etc

as i said, sure u can change to new account, but u may need to settle ex owner old bills.. as stated in POS that hte new bidder need to pay for the outstnding utilities bills etc
