Ansaldo Energia, an Italian power engineering company. It is based in Genoa.


The parent company, Ansaldo, started in 1853. It was taken over by Finmeccanica in 1993. In 2011, Finmeccanica (since 2016 Leonardo-Finmeccanica) sold 45% stake in Ansaldo Energia to First Reserve Corporation. In 2013, the Fondo Strategico Italiano acquired a 85% share of the company. It then sold a 40% share to Shanghai Electric Corporation.[2]


Ansaldo Energia is a producer of thermoelectric power plants, operating on international markets for customers ranging from Public Administration to Independent Power Producers and Industrial Clients. Ansaldo Energia covers the entire power generation spectrum with a combination of plant engineering, manufacturing and service activities. It has an installed capacity exceeding 166,000 MW in over 90 countries for thermal electric and hydroelectric plants. Revenues in 2007 stood at 979 million euros.[3]

The production centre is located in the Genoa - Campi area and is split into three product lines: gas turbines, steam turbines and generators.

Gas turbines

Ansaldo Energia manufactures gas turbines in the range from 70 to 280 MW, with more than 140 units delivered for a total installed capacity of more than 23,000 MW. The gas turbines models manufactured are named: AE64.3A, AE94.2, AE94.2K, AE94.3A and are based on designs by Siemens AG.

Because of the fusion with General Electric both European Union and United States competition regulators approved the deal by September 2015, subject to the divestiture of Alstom's large and very large gas turbine (GT26 and GT36 models) manufacturing and service business; and its GE7FA gas turbine aftermarket parts subsidiary business, Power Systems Mfg. LLC (PSM), to Ansaldo Energia
