As mentioned above, Italy gets the majority of its electricity supply from conventional thermal sources, the bulk of which are Oil-fired. The high cost of oil compared to other sources of thermal generation has caused Italian electricity consumers to pay some of the highest rates in Europe. In response, power generators have begun to switch to alternative fuel sources, especially Natural Gas and co-firing plants burning combinations of oil, natural gas, and Coal. Enel has announced that it would like to phase out all oil-fired power plants by 2008, though the current tightness of Italys electricity supply raises questions about the feasibility of this plan. Most new investment in electricity generating capacity in Italy has been in the form of gas-fired plants, specifically combined-cycle, gas-fired turbines (CCGFTs). In October 2005, Germanys E.ON announced that it would build a 800-MW CCGFT in Livorno. Also in 2005, Linate airport in Milan awarded a contract for the construction of a 24-MW, gas-fired cogeneration plant to supply electricity and heating. In 2004, Electrabel began construction of a 400-MW CCGFT in Rosignano. Eni power completed gas-fired power plants in Ravenna (780 MW) and Ferrera Erbognone (1,030 MW) in 2004; the company is also in the process of building plants gas-fired plants in Mantua (780 MW) and Brindisi (1,170 MW). Energia Italiana plans to build at least five new plants in Italy, each with a capacity of 780 MW and burning combinations of natural gas and coal. In 2004, Endesa spent some $690 million to convert several oil-fired plants into gas- or coal-fired.
