Our Battery-Based Energy Storage projects and achievements

Feature

By 2030, TotalEnergies aims to develop 5 to 7 GW of battery storage capacity, mainly in Europe and the United States. TotalEnergies is developing stationary electricity storage, notably through its subsidiaries Saft Groupe (Saft) and Kyon Energy.

Why develop battery-based energy storage?

The storage of electrical energy in batteries is an essential complement to renewable energies, which are intermittent by nature. On a large scale, it is essential for promoting the growth of renewables and enabling them to represent a significant share of the electricity mix. To achieve its goal, the Company relies on the technological expertise of Saft, which develops batteries based on nickel, lithium-ion, and primary lithium technologies. These batteries offer several advantages:

  • They are an indispensable partner to renewable energies, which are intermittent by nature;
  • They are crucial for renewable energies to develop and acquire a significant share of the energy mix;
  • They represent an effective solution to the growing need for flexibility in the electricity system;
  • They can be deployed quickly, are highly responsive, and have a limited land footprint;
  • They help meet the new challenges facing power grids today, in terms of congestion and stability.

Our projects in Europe

In France, we have 129 MWh of battery storage capacity. The battery farms are mainly installed at the Company's industrial sites: Dunkirk (61 MWh), Carling (25 MWh), and Grandpuits (43 MWh). Our sites are equipped with lithium-ion battery containers designed and assembled by Saft, delivering some of the best energy performance on the market in terms of both density and longevity (up to 20 years of service life).

In Belgium, TotalEnergies has launched its largest battery storage project in Europe (75 MWh) at the Antwerp platform, and another project is also underway at the Feluy depot (75 MWh).

In Germany, TotalEnergies acquired KYON, a company specializing in the development of battery storage projects in that country, in 2024. The Company also launched the construction of seven projects representing more than 600 MWh, with the first sites scheduled to come online in early 2026.

Our projects in the United States

In the United States, our two solar power plants located in Houston, Texas, are equipped with battery energy storage systems: Danish Fields (150 MW / 225 MWh) and Myrtle (150 MW / 225 MWh).
