Edison

Early history

Founded in 1884 by Giuseppe Colombo in Milan, Italy, as "Società generale italiana di elettricità sistema Edison", it served the purpose of introducing and applying Thomas Edison's inventions to Italy. Indeed, Colombo, an engineering professor, was a great admirer of Edison, whom he had met in the United States in 1881, securing an exclusive licence for some of his patents for Italy and hiring some of his collaborators. Edison operated Santa Radegonda power plant, Europe's first power plant. In the following decades Edison continued growing, especially in hydroelectric power, and came to control power distribution in most of northern Italy. In 1962 the centre-left coalition government of Christian Democrats and Socialists decided the nationalisation of the electric sector in Italy, in order to break the oligopolistic power of the four dominant electric companies that then dominated all the national market. With the compensation money it obtained from the state, Edison, then headed by Giorgio Valerio, invested heavily to diversify its activities, primarily in the petrochemical sector and by buying Standa supermarkets chain, continuing producing power only for self-consumption. However, this strategy was unsuccessful, as competition with both state-owned Enrico Mattei's giant Eni and Montecatini, a large private chemical company, proved too hard, so in 1965 Edison was eventually forced to merge with Montecatini, forming Montedison, the largest chemical company in the country.

Montedison era

Montedison initially was doing well, dominating about 80% of the national chemical market and 15% of the European Community market. However, the 1973 oil crisis proved disastrous for the company that was forced to seek state intervention in order to avoid bankruptcy; by the mid 1970s the Italian state came to own about 17% of Montedison, becoming its largest single shareholder, but its effective control was even greater as state-owned banks held shares. The company became increasingly an arm of state social policy and employment goals were favored over profits.In 1980 Mario Schimberni became chairman and negotiated the sale of the state-owned shares to Gemina, a consortium of banks and private companies, in order to free Montedison from government interference. Through a rigorous cost-cutting plan and joint-ventures with Mitsui and Hercules Inc. Schimberni transformed the money-losing manufacturer of commodity chemicals and plastics into a profitable diversified holding company.In 1985 Raul Gardini, an agri-business tycoon, started buying into Montedison, and by 1987 he came to own 40 per cent of the company's shares, thus taking over the company and forcing Schimberni to leave. Gardini wanted to reorganize and integrate the company into his sugar and fertilizer empire, but the debt burden he incurred during the takeover rapidly brought Montedison on the threshold of bankruptcy, forcing Gardini to seek state aid. In 1988 a new joint-venture was formed with Eni, called Enimont, in which both companies had 40 per cent of the shares, while 20 per cent was sold on the market. In 1990 Eni bought all Montedison's shares in Enimont, and Montedison withdrew from the chemical sector to pursue a role as an energy company.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.

As Edison S.p.A.

In 2001 a successful hostile bid to acquire Montedison was launched by Italenergia S.p.A., a consortium set up by Fiat, Electricité de France, Sanpaolo IMI, Banca Intesa and other investors. Following the takeover, Montedison was reorganized by selling all its non-energy assets. In 2002 Montedison was merged with Edison, Sondel and Fiat Energia under the name of Edison S.p.A. In 2005, Transalpina di Energia, a consortium set up by Electricité de France and A2A, purchased 63.3% of the common shares of Edison from Italenergia. In 2012, Electricité de France finally bought 99.5% of Edison's shares and delisted it from Milan stock exchange.
