Investment Thesis & Focus
- ArcLight says it pursues investments principally in “power, renewables, strategic gas, transformative and opportunistic infrastructure,” which it calls its Core Sectors.
- ArcLight’s stated focus is on middle-market opportunities where it believes it has advantages in sourcing operational management, driving value creation, financing, and monetizing assets.
- The firm emphasizes an operationally intensive approach supported by in-house strategic, technical, operational, and commercial specialists, plus a roughly 2,000-person asset-management partner.
- ArcLight’s strategic focus is on cash-generative real assets positioned around electrification, decarbonization, and powering the digital economy.
- In transformative infrastructure, ArcLight focuses on technologically established infrastructure supported by long-term contracts, with a preference for co-location with existing infrastructure assets or other sustainable competitive advantages.
- For opportunistic infrastructure, ArcLight says it is highly selective, focusing on long-term contracts, rigorous underwriting standards, and resilience to macro and policy risks.
