 In 1991 Montedison revived the name Edison to rebrand SELM, a spin-off company in which all its energy assets had been put in 1978.In 1999, the Bersani decree liberalized the Italian energy market and reintroduced competition in the electric market, and later the Letta decree opened up the natural gas market, allowing Edison to begin supplying electricity to eligible customers and expanding its downstream presence in the natural gas sector.In 2001 a successful hostile bid to acquire Montedison (that controlled Edison as a subsidiary) was launched by Italenergia S.p.A., a consortium set up by Fiat, Electricité de France, Sanpaolo IMI, Banca Intesa and other investors.
