ENGIE achievements and projects of 2025

Renewable energy

Renewable energies are the key to meet the energy challenges of the future while respecting our planet.

This is why ENGIE is developing sustainable and innovative solutions to provide cleans and renewable energy.

As an innovative producer of green electricity in Belgium, ENGIE has high ambitions in the field of renewable energy. By 2030, we intend to increase our onshore wind power to 1,000 MW and also our offshore wind power to 1,000 MW.

Finally, our hydroelectric plants provide clean, renewable energy to thousands of homes and businesses.

Flexible generation

ENGIE is actively involved in flexible generation projects to meet the needs of our customers, contribute to the continued security of energy supply, and help combat climate change.

Flexible production involves the use of technologies such as battery and pumped energy storage systems, gas-fired power plants and hydrogen production technologies.

These technologies can be used to meet fluctuations in energy demand, compensate for the intermittency of renewable energies, and ensure the stability of the electricity grid.

By 2030, ENGIE wants to guarantee 5,500 MW of flexible capacity in Belgium to account moments of low renewable production.

Client solutions

ENGIE supports its customers in reducing their carbon footprint by offering tailored and high-performance solutions adapted to their needs.

Our services help both residential and industrial customers optimize their energy consumption, benefit from flexible and cost-efficient solutions, and accelerate their transition towards low-carbon energy.

Through smart tools, innovative solutions and proven expertise, ENGIE positions itself as a trusted partner, supporting customers in achieving their sustainability goals while ensuring comfort, accessibility and performance.

Nuclear energy

Belgium has 7 nuclear power plants: 4 in Doel and 3 in Tihange.

ENGIE is responsible for the safe and professional operation of the two most recent reactors, Doel 4 and Tihange 3.
