The start of production for the Stillwater and Salt Wells plants will contribute to the state's goal of achieving a level of 20% power generation from renewable sources by 2015, the company said. With a total gross installed capacity of 65MW, the two plants will generate some 400 million kWh of electricity per year, enough to meet the energy needs of roughly 40,000 American households, while avoiding the emission of more than 300,000 tons of CO2 per year. Francesco Starace, head of Enel's new renewable energy division, said: "Backed by a century of experience in Italy, Enel today is a leading player in geothermal power in the US, as well, with one plant that is already operational and a portfolio of projects that are in advanced stages of development for a power capacity of more than 150MW in Nevada, California and Utah."
