HOUSTON, TEXAS (Editors at Energy Analytics Institute, 26.Mar.2025) — TotalEnergies, on the occasion of Patrick Pouyanné’s participation in the Europe 2025 conference in Berlin, and in connection with the company’s integrated development in Germany’s electricity sector, revealed investment decisions for 6 battery storage projects with 221 MW of new storage capacity and an investment outlay of €160mn.
Kyon Energy, a TotalEnergies affiliate, will develop the projects, which were acquired in 2024, the French energy giant said on 26 Mar. 2025 in an official statement.
“We are delighted with this significant step forward in the development of our integrated power activities in Germany, Europe’s largest electricity market. The implementation and integration of all these battery projects will allow us to supply our customers with clean firm power, contributing directly to our targeted 12% profitability in this activity,” TotalEnergies chairman and CEO Pouyanné said in the statement.
Most of the projects will use next-generation batteries supplied by Saft, another TotalEnergies affiliate and involved in advanced battery technology. Construction began in late-2024, and commissioning is planned for early-2026, according to TotalEnergies.
TotalEnergies expands integrated power operations in Germany
These batteries round out TotalEnergies’ German electricity portfolio, which consists of:
- 7 GW1 of onshore wind and solar in development and 200 MW installed or under construction, subject to the closing of the VSB acquisition;
- 6.5 GW net of offshore wind in development;
- 2 GW of storage capacity in development and 321 MW under construction;
- 9 GW of electricity aggregation capacity managed by Quadra Energy; and
- 6,900 developed and operated charge points, including 1,100 with high-power charging.
Energy storage, a key part of integrated electricity strategy
Energy storage plays a key role in offsetting the intermittency of renewable power. Their development is therefore necessary to enable TotalEnergies to offer Clean Firm Power to its customers, i.e. the continuous, stable supply of renewable electricity. Batteries also help to maximize the value of TotalEnergies’ portfolio, especially through its trading activities, the company said.
TotalEnergies leverages the expertise of its Saft affiliate for the supply of the best battery storage systems for its needs.
“The launch of these projects marks a major milestone in TotalEnergies’ development of battery energy storage capacity in Germany, where the company has operations in the production, trading, aggregation and commercialization of clean firm power. This storage capacity will allow TotalEnergies to contribute to the resilience of the German power system, by reducing congestion and adding flexibility in order to quickly boost the country’s renewables sector,” the company said.
