Our history
ENGIE’s history spans more than a century. From one generation to the next, we have written our industrial story in time with transformations in the world and in energy, so we can always evolve to better meet the needs of economies and society.
Multiple origins
ENGIE’s history begins in the early 19th century, at the dawn of the industrial revolution. With diverse roots, we helped shape the European energy landscape very early on, which explains our footprint today in France and Belgium, and our global reach.
In Belgium, Société Meeûs & Cie, one of our ancestors, was among the pioneers of electricity and gas as early as 1862. It became Tractebel in 1986, then created Electrabel in 1990, establishing itself as the leading producer and supplier of electricity in Belgium. Tractebel rapidly expanded internationally, particularly in Latin America with several major hydropower plants.
In Egypt, in 1858, Ferdinand de Lesseps founded the Compagnie Universelle du Canal Maritime de Suez, a visionary project opening a direct route to the Middle East and Asia. We would retain the Suez name as part of our heritage for many years.
In France, Société Lyonnaise des Eaux et de l’Éclairage (SLEE) played a key role in gas distribution and the rise of electricity during the Belle Époque, transforming cities by democratizing public lighting.
These three trajectories converged in 1997: Lyonnaise des Eaux merged with Compagnie Financière de Suez, which took control of Tractebel and Electrabel, establishing itself as a major energy player in Europe.
Energy for all
In the aftermath of the Second World War, under the impetus of the French government, which decided to nationalize the energy sector as part of a major reconstruction plan, we were called upon to play a key role for decades to come by becoming Gaz de France (GDF).
On 8 April 1946, the French government nationalized the energy sector and created Gaz de France (GDF) and Électricité de France (EDF). Their mission was to support the country’s reconstruction by ensuring a reliable and efficient energy supply.
In the 1950s, GDF supported the rise of natural gas, which gradually replaced town gas. The discovery of the Lacq field in the Pyrénées-Atlantiques in 1957 led to the rollout of a national network of exceptional density.
Faced with growing demand, GDF reinvented itself in the early 1970s by signing import contracts with the Netherlands and Algeria, and by developing storage and transmission infrastructure.
In the early 2000s, the opening of the energy market to competition transformed GDF. Distribution and transmission activities were separated, giving birth to GRDF and GRTgaz (renamed NaTran in 2025).
The merger of giants: GDF SUEZ
2008 marked a major milestone in our history. The merger of GDF and Suez brought together complementary expertise, from natural gas to electricity, from nuclear to renewable energy, as well as energy services. A new path opened up for a global energy player.
The merger of GDF and Suez in 2008 made our Group a major player in the global energy sector. As the leading gas supplier in France and the leading infrastructure operator in Europe, it rapidly expanded its activities in electricity production and supply.
Our portfolio diversified: engineering, management of electrical installations, district heating and cooling networks, water management and waste treatment. In 2012, the acquisition of International Power propelled the Group to the rank of world leader in independent electricity production and opened new markets in South America, the Middle East and Southeast Asia.
The first renewable energy projects emerged, paving the way for the energy transition. In 2017, the sale of exploration and production activities in hydrocarbons marked a decisive turning point: we committed fully to decarbonization. The transformation was underway.
A new brand to champion the transition: ENGIE
2015 was a historic year for the climate, with the signing of the Paris Agreement. We also committed to tackling climate change. It was a new chapter in the history of energy, and in our own history: GDF SUEZ became ENGIE.
From day one, ENGIE is mobilized to support the energy transition. We committed to phasing out coal by 2027 and significantly scaling up renewable energy. In 2020, this commitment became our purpose: to act to accelerate the transition towards a carbon-neutral economy.
In 2021, we adopted an ambitious strategic plan targeting Net Zero Carbon by 2045. ENGIE refocused on its core energy businesses, accelerated in renewables and invested in batteries and energy storage. Between 2017 and 2024, we reduced our CO₂ emissions by 41% and increased our renewable capacity by 88%.
The 2022 energy crisis, triggered by the invasion of Ukraine, confirmed our vision: to develop local renewable energy to guarantee Europe’s energy sovereignty.
Today, drawing on more than 150 years of history and thanks to our 90,000 employees, we invest an average of 10 billion euros per year to build a decarbonized, reliable and affordable energy system.
