Paris, December 17, 2025 – French oil and gas giant TotalEnergies SE has announced the sale of 50% of its 424-megawatt (MW) renewable energy portfolio in Greece to Spanish investment firm Asterion Industrial Partners for 254 million euros ($297.36 million). The transaction values the portfolio at 508 million euros, roughly 1.2 million euros per megawatt installed, underscoring the growing interest in renewable energy investments in Europe.

Under the agreement, TotalEnergies will retain a 50% stake and continue to operate the Greek wind and solar assets. The company plans to market and sell most of the electricity generated once the current regulated tariffs expire, positioning the assets for potential growth in merchant power sales.

TotalEnergies’ Global Renewable Strategy

TotalEnergies currently owns 32 gigawatts (GW) of gross installed renewable capacity worldwide, placing it ahead of many other oil majors in the clean energy sector. However, the company often relies on partial divestments of minority stakes in operational wind and solar farms to unlock capital and boost returns. These assets typically earn fixed government-set tariffs, providing stable and predictable cash flows, making them attractive to investors seeking low-risk renewable energy exposure.

This strategic divestment aligns with TotalEnergies’ broader approach to balancing renewable expansion, debt reduction, and shareholder returns. Following a series of acquisitions in early 2025, the company’s debt-to-equity ratio more than doubled, prompting investor pressure to accelerate asset sales and reduce overall leverage.

Significance for Greece and European Renewable Markets

The deal highlights Greece’s growing role in European renewable energy development, particularly in wind and solar power. TotalEnergies’ continued operation of the assets ensures ongoing technical management and efficiency, while Asterion Industrial Partners’ investment brings additional capital for operational and growth initiatives.

Analysts note that such partial stake sales are becoming common among energy majors seeking to fund new renewable projects without overextending their balance sheets. By selling minority stakes in mature renewable assets, companies like TotalEnergies can maintain operational control while freeing up cash to invest in next-generation green energy technologies.

Future Outlook

As Europe accelerates its transition toward sustainable energy, transactions like TotalEnergies’ sale reflect the dual pressures of investor expectations and strategic growth in renewable capacity. The French energy company is likely to continue leveraging minority stake sales, partnerships, and joint ventures to expand its renewable footprint while managing financial risk.
