ENGIE Acquisitions
ENGIE pursued strategic acquisitions to expand its global footprint and strengthen its position in high-growth energy markets. The company focused on power generation capacity and energy infrastructure assets.
The acquisition of International Power between 2010 and 2012 represented a transformative deal. The company initially acquired 70% in 2010, creating the world’s largest independent power producer. The enlarged entity retained International Power’s London Stock Exchange listing while GDF SUEZ held controlling interest.
In 2012, ENGIE completed the acquisition of the remaining 30% stake for full ownership. This transaction gave the company control of International Power’s development pipeline in emerging markets, representing approximately 13 GW of generating capacity under construction. The acquisition added over 66 GW of power generation across regions including South America, the Middle East, and Southeast Asia.
The purchase of Balfour Beatty WorkPlace in 2013 expanded ENGIE’s energy services capabilities in the United Kingdom. Operating under the Cofely brand, this acquisition created a business with over 15,000 employees and nearly £1 billion in turnover. The deal consolidated the company’s position in energy services, technical services, and facilities management across commercial, industrial, and public sectors.
In 2019, ENGIE acquired 90% of Transportadora Associada de Gás in Brazil for €7.7 billion. This represented the largest acquisition since International Power, giving the company control of Brazil’s largest natural gas transmission system. TAG operates 2,800 miles of pipeline, comprising 47% of Brazil’s gas infrastructure.
