SUSI Partners

SUSI Partners

SUSI Partners was founded in 2009 by Marco van Daele and Tobias Reichardt, two former energy finance professionals who saw a gap in dedicated energy-transition investment vehicles. The firm is headquartered in Zug, Switzerland, with additional offices in Milan and Berlin, and operates as an independent asset manager rather than a family office. The firm's strategy spans the full capital structure of energy-transition projects. SUSI runs equity funds focused on renewable energy infrastructure (solar, wind, biomass) alongside a private credit platform that provides project finance and mezzanine debt for decarbonization initiatives. Its geographic focus covers Western Europe and select North American markets, with confirmed investments in solar portfolios in Italy, wind farms in Sweden, and district heating networks in Germany. The firm also manages a dedicated energy-efficiency fund targeting industrial companies. SUSI Partners has deployed over €2 billion since inception, according to public records. The firm's team of roughly 55 professionals includes engineers, finance specialists, and legal experts. In early 2025, SUSI closed its second energy-transition credit fund at €450 million, exceeding its original target (per pv magazine, February 2025). The firm also maintains a research arm that publishes sector reports on renewable energy markets. The firm's structural differentiator is its independent, sector-specialist model — it is not a captive arm of a larger financial group or a family office. It competes alongside generalist infrastructure funds but operates with a narrower mandate and deeper technical expertise, which it argues produces better risk-adjusted returns in the fragmented mid-market energy-transition space.
