• ENGIE’s BESS project for installed capacity of 100 MW has been selected in the 4th Capacity Remuneration Mechanism (CRM) auction in Belgium.
• With this new project, ENGIE reaches 500 MW of BESS capacity in Europe, either installed, under construction or at an advanced stage of development.

On 31 October 2024, Belgian grid operator Elia announced the result of the country’s 4th CRM auction and the selection of ENGIE’s Battery Energy Storage System (BESS) project in Kallo. This project for a new 100 MW lithium-ion battery farm, for which the permit application was submitted in March 2023, will be supported by a 15-year capacity contract starting in November 2028. Once operational, the batteries will supply energy for four hours, i.e. 400 MWh or the equivalent of 80,000 domestic batteries at 5 kWh, covering the equivalent electricity consumption of more than 48,000 households. This project will contribute to the region’s energy transition and the remediation of the site of the former Kallo power plant, which was fuelled by natural gas and fuel oil until its closure in 2011.

With the development of this new farm, ENGIE is strengthening its position in battery energy storage in Europe. The Group now has a portfolio of 17 projects in Europe, either in operation, under construction or at an advanced stage of development, totalling 500 MW of installed capacity. Located in Belgium, the United Kingdom, the Netherlands, France, Italy and Germany, these projects will help to ensure the reliability of the European energy system and its security of supply.

“This new project is an important step in our drive to increase battery energy storage capacity in Europe and demonstrates the effectiveness of the Capacity Remuneration Mechanism in developing these assets. This increased pace in battery deployment is part of a growing need for flexibility to ensure the balance of European electrical grids as the proportion of renewable energies increases, wind and solar in particular. As a major player in the development of flexibility assets, which are essential to the energy transition, ENGIE currently has more than 2 GW of battery capacity in operation worldwide, and is aiming for installed capacity of 10 GW worldwide by 2030,” says Sébastien Arbola, Executive Vice President in charge of Flex Gen & Retail
