Private equity and private debt infrastructure targeting sustainability and the energy transition



Clean energy and greenfield specialists, investing in essential new infrastructure that accelerates the transition to net zero.

Sosteneo specialises in private equity energy infrastructure with a dedicated focus on greenfield projects related to the energy transition.

Sosteneo’s pure-play strategy targets essential new infrastructure projects in OECD Europe and Asia Pacific that accelerate the transition to net zero. Sosteneo invests in a wide range of technologies with a focus on infrastructure that produces clean energy, such as solar PV and wind, as well as infrastructure that enables clean energy use, such as battery storage and networks. There is also the potential to explore other investments in clean energy infrastructure on an opportunistic basis through bespoke solutions with partners.

An experienced, global team of specialists that can provide direct access to the market opportunity

The growth of net-zero commitments, the cost competitiveness of renewables, and an increased emphasis on energy independence are all supportive of the energy transition, which the Sosteneo team considers to be fundamentally a greenfield opportunity. This transition represents a major global buildout of infrastructure and substantial investment in new projects that offer the potential for stable, contracted income. The Sosteneo team has decades of experience in managing the unique risks associated with greenfield-stage investing and an established reputation with a network of industrial partners. The team is based in Milan, providing a platform for long-term investing across both Europe and Asia Pacific.
