As the world’s leading independent power producer, ENGIE combines hydroelectric power, onshore and offshore wind, solar, nuclear, geothermal, biomass and natural gas. This low-carbon energy mix meets the variety of uses and expectations of the Group’s customers, ensuring a continuous and sustainable power supply.
BREAKDOWN OF ENGIE GENERATION CAPACITY BY TECHNOLOGY

Enhanced monitoring of wind performance with LIDAR
LIDAR (Light Detection And Ranging) provides precise measurements of wind speed and direction up to 400 meters from wind farms. LIDAR is a remote sensor system that uses optic technology to measure the properties of a target. Wind measurements that use traditional methods are often distorted by the turbine’s blades. To avoid this problem, LIDARs can be installed next to the traditional anemometer located on wind turbine platforms. With this technology, measurements can be taken before wind reaches the turbine blades, providing precise calculations of wind speed and direction from a distance of up to 400 meters. In January 2012, Laborelec installed its first LIDAR at a Belgian wind farm operated by Electrabel. Wind measurements are then crossed with other measurements (power, blade speed, etc.) in order to improve the performance of ENGIE wind turbines.
The CSP (Concentrated Solar Power) project in Chile
Concentrated solar power (CSP) offers a new form of renewable energy technology. CSP uses mirrors to concentrate sunlight on photovoltaic cells or sensor tubes to produce steam or electricity. The goal of ENGIE’s Research & Innovation project is to develop and operate a CSP pilot project using the Linear Fresnel model, which produces steam without a heat transfer fluid. The steam will then be injected into the high-pressure turbine at the Mejillones coal plant in Chile.
