SUSI Partners

SUSI Partners is a specialist investment manager focused on mid-market energy transition infrastructure, directing institutional capital into assets and businesses that support a lower-carbon energy system. Now part of Gresham House, the firm draws on deep sector expertise and a track record spanning sustainable energy infrastructure. Its investment strategies cover equity, credit and Southeast Asia. Equity strategies invest in assets and platforms that develop, construct, acquire and operate energy transition infrastructure, while credit strategies provide flexible financing to project originators, from senior-secured to junior financing. The Asia strategy focuses on de-risking projects in Southeast Asia’s emerging markets.

SUSI Partners invests across renewable energy generation, including solar and onshore wind, as well as energy storage, smart energy solutions, energy efficiency, electric vehicle charging and the decarbonisation of heat. Its approach combines active risk management and value creation with partnerships and attention to environmental, social and governance standards. The firm focuses primarily on Europe and Southeast Asia, with selective exposure to other OECD countries, and reports estimated avoided emissions to clients using technology-specific methodologies.
