Total Energies BESS Strategy, €5.1 B EPH JV, 221 MW German Projects, and the 1 GW Mirny FID (2025-2026)

Industry Adoption, Total Energies BESS Strategy via Acquisition

In 2025, Total Energies executed an aggressive pivot from incremental project development to large-scale acquisition, rapidly scaling its battery energy storage system (BESS) footprint to establish a commanding market position, particularly in Europe. This marks a strategic acceleration from the 2021-2024 period, which was defined by more discrete project wins and organic growth. The company is now using its significant capital to buy entire project pipelines and operational assets, a “buy versus build” approach designed to accelerate its market entry and capture immediate revenue streams from grid services and flexible power generation.

Total Energies’ Shift to Portfolio Acquisition

The company’s strategy crystallized with several large-scale transactions in 2025, indicating a clear intent to acquire market share rather than build it project by project. This approach provides immediate scale, expert teams, and de-risked project pipelines.

• The most significant move was the November 2025 deal to acquire a 50% stake in a joint venture with Energetický a průmyslový holding (EPH) for €5.1 billion, which included gigawatts of battery storage assets and doubled the company’s European power production capacity.
• This followed the late 2024 acquisitions of Kyon Energy, a leading German battery storage developer, and VSB Group, which brought a substantial renewables and storage pipeline, immediately positioning Total Energies as a key player in the German market.
• In the UK, a June 2025 acquisition of a development pipeline from Low Carbon added 350 MW of solar and 85 MW of battery storage projects, securing future growth in another critical European market.

Integration of BESS with Renewable Generation

Beyond standalone storage, Total Energies is integrating BESS with its renewable energy projects to provide reliable, dispatchable power and capture higher value. This is evident in both new developments and strategic partnerships, moving storage from an ancillary service to a core component of its energy offerings.

• The Final Investment Decision (FID) for the 1 GW Mirny wind project in Kazakhstan, announced in April 2026, includes a large, integrated BESS component, demonstrating the company’s model for new large-scale renewable developments.
• In May 2025, Total Energies co-invested with Royal Golden Eagle (RGE) to develop a solar plant and associated BESS in Indonesia, part of a plan to export 1 GW of renewable electricity to Singapore.
• The company is also bundling storage with power purchase agreements (PPAs) for high-demand clients like data centers, as signaled in February 2026, allowing it to secure premium pricing for firm, low-carbon power.

€5.1 B in Deals, Total Energies Investment Strategy

Total Energies’ investment strategy is defined by a dual-track approach: funding its aggressive expansion into renewables and storage through its profitable legacy oil and gas operations while recycling capital through strategic divestments. The major acquisitions in 2025 were balanced by a disciplined capital expenditure plan and asset rotation model, ensuring financial sustainability while pursuing ambitious growth targets. This contrasts with the more cautious investment profile of peers like Equinor.

Total Energies’ Landmark Capital Deployments

The company made several multi-billion-dollar investments to secure its position in the flexible generation and storage market. These moves were not speculative but were aimed at acquiring established assets and pipelines with clear paths to revenue.

• The cornerstone transaction was the €5.1 billion ($5.9 billion) investment for a 50% stake in the EPH flexible power generation joint venture in November 2025, which significantly expanded its presence across Europe.
• In Germany, a €160 million ($172.7 million) investment was announced in March 2025 for six new BESS projects totaling 221 MW, demonstrating a focused effort to dominate Europe’s largest power market.
• To support its long-term growth, the company set a target to develop between 5 GW and 7 GW of battery storage capacity by 2030, signaling a sustained, high-level capital commitment to the sector.

Total Energies’ Capital Recycling Model

To fund its expansion, Total Energies employs a “develop and sell-down” model, divesting partial stakes in mature renewable portfolios to recycle capital into new growth projects. This allows the company to maintain operational control and a significant stake while de-risking its balance sheet.

• In September 2025, Total Energies sold a 50% stake in its 1.4 GW North American solar portfolio to KKR for a valuation of $1.25 billion, freeing up capital while retaining half ownership and operational duties.
• A similar deal occurred in December 2025, with the divestment of 50% of its 424 MW wind and solar portfolio in Greece to the investment firm Asterion.
• Following its major acquisitions, Total Energies revised its annual net capex guidance down by $1 billion per year to a range of $14-16 billion for 2026-2030, reflecting a disciplined allocation strategy that balances large-scale M&A with sustainable investment.

Europe vs. Global, Total Energies Geographic Expansion

Total Energies’ geographic strategy for energy storage is heavily concentrated on Europe, with Germany as the clear epicenter of its BESS development, while selectively entering high-growth markets in North America, the Caribbean, and Asia. This European focus intensified dramatically in 2025 through major acquisitions, shifting from the more globally distributed, project-based approach seen between 2021-2024. The company is leveraging its established presence in European power markets to build a leadership position in grid flexibility, a strategy different from the US-centric approach of competitors like Chevron.

Dominance in the German Market

Germany has become the primary target for Total Energies’ battery storage ambitions, driven by the country’s rapid renewable energy expansion and the resulting need for grid stabilization. The company has used a combination of direct investment and acquisition to build a formidable presence.

• In March 2025, the company committed €160 million to build six new BESS projects totaling 221 MW, adding to a portfolio that already had 100 MW under construction.
• By November 2025, Total Energies further solidified its German position by partnering with Allianz GI to develop another 800 MW of battery storage projects, a move designed to capture a significant share of the grid services market.
• The acquisition of Kyon Energy in late 2024 was a foundational move, providing a ready-made pipeline of 770 MW of advanced-stage projects and a team with deep expertise in the German regulatory environment.

Selective Expansion into New Markets

While Europe is the core, Total Energies is making strategic entries into other regions with favorable regulatory frameworks and growing demand for renewables and storage. These moves are typically executed through joint ventures or portfolio acquisitions with established local players.

• In July 2025, the company entered the Caribbean market by acquiring a 50% stake in AES Dominicana’s renewables portfolio, gaining a share in over 1 GW of contracted assets including wind, solar, and BESS.
• A framework agreement was signed in February 2025 with Masdar and EPoint Zero to explore clean energy projects, including energy storage, in India, signaling a potential major expansion into one of the world’s fastest-growing energy markets.
