Deux-Acren, in Belgium, hosts the largest energy storage plant in Continental Europe developed by Corsica Sole.

A dependence on fossil fuels

In Deux-Acren, the plant can store up to 100MWh of energy in lithium-ion batteries at a power level of up to 50MW. This power will be used to regulate the frequency of the European electricity transmission network. The commissioning of this plant is the culmination of several years of work in partnership with Tesla, Yuso and InnoVent.

Energy storage helps to stabilize electrical networks by ensuring the balance between production and consumption. Currently, oil or gas-fired power plants perform this function. Thus, the European network remains dependent on fossil fuels.

A strategic issue

It is vital today for the European Union to be able to control its energy production and therefore its costs. In addition to being economical, storage plants can be built in less than a year. In addition, they allow a rapid response to the energy crisis.

Michael Coudyser, General Manager of Corsica Sole, says:

“A pioneer in energy storage in France, Corsica Sole has been operating this type of plant in the French islands since 2015. This project is an important step for the development of electricity storage solutions in Europe. We financed this project with our shareholder Mirova Energy Transition 5 without any public subsidy. By demonstrating that large-scale battery deployment is economically viable, we are proving that we can build a world based on Renewable Energies coupled with energy storage. With this project, Corsica Sole changes scale and becomes one of the European leaders in the sector. The multiplication of this type of project is a strategic issue to guarantee Europe’s energy sovereignty.”

Corsica Sole’s ambition is to accelerate the energy transition to a world that is 100% renewable and 0% fossil fuel. Thus, the company seeks to help the territories to develop their natural resources to achieve their energy sovereignty.
