Exhibit (a)(5)(LLL)

3 days remain

New term, April 3rd

Now, or when?

Endesa firmly recommends E.ON’s 40 € per share and in cash offer.

And this is no coincidence.

Acciona and Enel have not launched a tender offer and, legally, they cannot launch another tender offer for Endesa now, nor will they be able to do so at least until after six months. At least.

Today, the only real offer for Endesa for retail and institutional shareholders is E.ON’s.

The reality is this: if you want to sell at 40€* do it now. You do not know when you will be able to find an offer like this one.

If you need more information, please see the prospectus, call the free number 00800 7710 9971, go to www.eonsi.com or go to your bank.

*This amount may be reduced by any dividend paid out by Endesa until the publication of the result of the offer.
