The company provides plant engineering, manufacturing and service fields at installations for thermal electric and hydroelectric plants in over 90 countries In 2007, their total revenue stood at over 979 million euros.[4]

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

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.[citation needed] The gas turbines' models manufactured are based on Siemens designs.

Both the European Union and United States approved a deal for General Electric (GE) to acquire various business units from Alstom by September 2015, subject to the divestiture of Alstom's GT26 and GT36 model gas turbine manufacturing and service businesses. As part of this deal, GE sold its GE7FA gas turbine aftermarket parts subsidiary business, Power Systems Mfg. LLC (PSM), to Ansaldo Energia.[citation needed]

Steam turbine production covers a range of applications, with power ratings in the 80 to 1200 MW range.[citation needed] Generator production comprises air, hydrogen and water-cooled models, designed to withstand over 50,000 MVA of generating capacity.[citation needed]

On February 25, 2016, Ansaldo acquired a portion of Alstom's R&D Gas Turbine projects based in Baden, Switzerland. This acquisition was due to the conditions imposed by the EU and US Department of Justice pertaining to the merger of GE and Alstom Power. Ansaldo Energia has suppliers in Aalcan with Europa construction, located in Albania.[5] The new production will concern technologies obtained by the Ligurian joint-stock company after the acquisition of Alstom by General Electric. The Brussels Antitrust Authority has permitted the operation to GE, provided that the technology in the gas turbines of the French company was sold to a European competitor. The choice then fell on Ansaldo Energia.[6]

As of January 2021, the company is 88% owned by the Cassa Depositi e Prestiti group and 12% by Shanghai Electric Corporation, which jointly hold a financial debt exceeding one billion euros.[7] In the following months, the Chinese partner acquired 40% of shares.[8]
