Focus on ENGIE’s activities in Chile


By ENGIE - 05 March 2024 - 15:46

In line with its strategic objective of being net zero carbon by 2045, the Group has made the decision to close its coal-fired power plants in the country by the end of 2025. Instead, it's embracing renewables and batteries to inject more green energy into the Chilean grid.

  • ~1,200 collaborators

  • 4 operator in generation with 2.5 GW installed capacity

  • #3 operator in transmission with ~2,400 km of lines

  • 1,066 km of gas networks


Since 2018, ENGIE has made remarkable progress, shifting from just 1% renewable energy in its mix to over 30% today. And it's aiming even higher, with a target of hitting 60% by 2025-27. This means renewable capacities will surge from 800 megawatts to 2.1 gigawatts in just three years. To achieve this ambitious goal, the Group invests 1.8 billion euros between 2023 and 20271.


"We're all thrilled to be playing a part in the energy transition which is happening right before our eyes," says Rosaline Corinthien, CEO of ENGIE Chile.

As the fourth largest energy producer in Chile, ENGIE is aligning its efforts with the government's vision of achieving carbon neutrality by 2050. While solar and wind made up only 12% of the national electricity production in 2018, they now account for over 31%. When you add hydroelectric power into the mix, an impressive 65% of Chile's electricity is renewable.

The South American country enjoys some of the world's highest solar and wind exposure rates. However, its decarbonization ambitions face challenges due to limitations in its electrical grid...


Enter batteries: the key to stabilizing the electrical grid

In 2023, 10% of renewable energy production of Chile was lost, and there's a possibility “that figure could rise to 15% this year,” notes Rosaline Corinthien. Every day, between 10am and 3pm, there's an excess of supply over demand, causing the grid to become saturated. Despite ENGIE operating 2,400 km of high-voltage lines as the country's third largest energy transport company, Chile's infrastructure is still insufficient to transmit decarbonized electricity efficiently from the Atlantic coast and the Atacama Desert to major cities in central and southern regions. To address this issue, the national grid operator is currently constructing a second power line from north to south, slated to be operational by 2031.

In the meantime, ENGIE is leveraging flexibility. By integrating batteries with its solar parks, the Group can store surplus production during the day and release it at night. This approach have been implemented in several parks. 

Batteries are becoming increasingly indispensable, especially as ENGIE plans to shut down its remaining coal-fired power plants in Mejillones by 2025. These plants currently contribute 1 gigawatts of ENGIE's 2.5 GW production capacity in Chile. One of these plants is going to be converted to gas, offering a swift energy solution to stabilize the grid.

By the end of 2022, ENGIE had already closed the two remaining coal units in Tocopilla, located 130 km north of Mejillones, following a well-thought-out transition plan.

Phasing-out coal in Chile: How ENGIE is taking care of its employees

In 2021, ENGIE announced its exit from coal in Chile, with a phase-out starting in 2022 and meant to be completed by 2025. As this transformation has a significant impact on the local economy, the Group, putting its stakeholder at heart, implemented a Just Transition plan. The goal is to mitigate negative externalities and generate positive ones. Learn more


Flexibility: How ENGIE is Combining Renewables and Batteries in Chile

In northern Chile, the Group is building three battery storage systems to support Coya, Tamaya, and Capricornio solar power plants, representing a total of 1.1 GWh of daily storage capacity. These projects move the Group closer to achieving its target of installing 10 GW of battery capacity by 2030. Learn more
