Investment thesis

SUSI Partners invests solely in energy transition infrastructure across equity (Core+ and value-add), credit, and an Asia-focused strategy. It targets assets with infrastructure characteristics — capital-intensive real assets generating long-term, low-cycle-correlation cash flows — investing up to EUR 150 million per opportunity in the mid-market. Key themes include producing clean energy (solar PV, onshore wind), enabling clean energy integration (storage, smart energy), increasing energy efficiency via infrastructure-as-a-service models, and electrifying energy use (EV charging, heat decarbonisation). It focuses on Europe and Southeast Asian emerging markets, invests only in proven technologies, applies active value creation and ESG standards, and reports measurable avoided greenhouse gas emissions.
