In December 2000 Enel S.p.A. set up a Medium Term Note Programme allowing it to issue Eurobonds in either the Public Market or in the Private Market, in the form of 'Private Placements', using the same documentation.
The initial maximum amount of the Programme was Euro 3 billion.

This amount was subsequently amended in May 2001 raising the limit for bonds issued to Euro 7.5 billion, and including Enel Investment Holding B.V. as an issuer (guaranteed by Enel S.p.A.) In November 2003 the programme was again amended raising the limit for bonds issued to Euro 10 billion.

In November 2005, due to the reorganization of foreign companies of Enel Group, Enel Investment Holding BV was replaced with Enel Finance International S.A. (guaranteed by Enel S.p.A.).

In May 2007, the amount of the programme was raised to Euro 25 billion while in November 2011 the programme has been raised up to Euro 30 billion. In January 2013 the  amount of the programme has been raised up to Euro 35 billion.
