Located a few kilometers from the Belgian border, in Dahlem, North Rhine-Westphalia, the electricity storage site will have batteries with capacities of 200 megawatt hours and 100 megawatts of power.
They will be designed with lithium-iron-phosphate (LFP) technology, common in electric cars, in a system based on containers, developed by Saft, a subsidiary of TotalEnergies.
Two other companies, recently acquired by TotalEnergies, will participate directly in the project: Kyon Energy, purchased in February, developer of storage systems, and Quadra Energy, acquired in October, which will serve as an intermediary in the sale between the electricity producer and customers.
Commercial commissioning of the project is planned for the second half of 2026.
In February, the CEO of TotalEnergies refuted any "disengagement" of his company in renewable energies, after the sale of half of the group's stakes in certain projects, which he explained by the desire to achieve better profitability and better manage risks.
Presenting itself as the "largest French investor in renewable energies", the group had a total of 2023 gigawatts of renewable electricity capacity in 22,4, slightly above its objective, and is aiming for 100 gigawatts in 2030.
As in 2023, TotalEnergies plans for 2024 to allocate a third of its total investments to what it calls “low-carbon energies”, including around $5 billion in its “electricity” branch.
This brings together wind power, solar power, electricity storage by batteries, but also its gas-fired thermal power plants (thus based on fossil energy), which TotalEnergies presents as an essential link in the renewable energy chain. to compensate for their intermittency.
