Enel payments

Hi wonder if anyone can give me some quick advice?

I'm a Brit, temporarily living in Spain with a little house in Abruzzo. For some time I've been sending a neigbour money to pay Enel etc, but it's time I started to do things for myself. I need to do a bank transfer from Spain as I don't think I can use either my Spanish or British accounts to pay Enel directly.

I need to find the right IBAN/Bic code to make a payment to Enel urgently. Problem is I have found a webpage on the Enel site 'pagamento dall'estero' that gives the IBANs of several banks. Problem is whhich of them is correct for my area in Abruzzo or are any of them ok to use? I don't want to be paying the wrong account, because then i would have to get the bank to reverse the transaction.

The other problem is that I will have to change the name on the account, but that is another question.

Thanks in advance for any advice you can offer.
