TotalEnergies pursues growth in electricity by launching six new battery storage projects

TotalEnergies has announced investment decisions for six battery storage projects in connection with the company’s integrated development in Germany’s electricity sector. In total, these projects amount to 221 MW of new storage capacity and an investment outlay of €160 million, TotalEnergies said in a statement.

The projects were developed by Kyon Energy, a TotalEnergies affiliate acquired in 2024, and most will use next-generation batteries supplied by Saft, a TotalEnergies affiliate and leader in advanced battery technology. Construction began at the end of 2024, and commissioning is planned for early 2026, the company said.

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 commercialisation 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.

TotalEnergies expands integrated power operations in Germany

The battery projects round out TotalEnergies’ German electricity portfolio, which consists of:

• 7 GW of onshore wind and solar in development and 200 MW¹ installed or under construction
• 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
• 6,900 developed and operated charge points, including 1,100 with high-power charging.

“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,” said Patrick Pouyanné, Chairman and CEO of TotalEnergies.

Energy storage plays a key role in offsetting the intermittence 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 maximise the value of TotalEnergies’ portfolio, especially through its trading activities.
