Sarlux, the world's largest IGCC power plant, was completed in 2000 by a consortium including Snamprogetti SpA (Milan) and GE Power Systems. This facility began producing electricity from syngas in September 2000. The project is located on the Italian island of Sardinia at the Saras Oil Refinery in Sarroch (the second largest European refinery). The plant gasifies 1.1 million metric tons per year of the tar-like residue produced by vacuum visbreaking at the refinery. It produces: 551MWe (net) of electricity; 285 metric tons of process steam for the refinery; and 20 million standard cubic feet a day of hydrogen. The electricity is sold to ENEL, Italy's state-controlled electric company.
