ArcLight Infrastructure Partners Fund VIII

ArcLight Infrastructure Partners Fund VIII is the eighth institutional infrastructure fund managed by ArcLight Capital Partners, a Boston-based firm founded in 2001 that has established itself as one of North America’s leading specialists in energy and infrastructure investment. The fund reached its final close on April 7, 2026, with $3.9 billion in capital commitments, surpassing its $3.0 billion target by approximately 30 percent and marking the firm’s largest fundraise to date. The oversubscribed close reflects sustained institutional demand for well-managed energy infrastructure strategies amid the global energy transition.

Fund VIII pursues value-added infrastructure investments focused on assets critical to electrification and the digital economy, concentrating on electric power generation, renewable energy (solar, wind, and hydroelectric), battery storage systems, electric transmission networks, natural gas transmission and storage, and digital power infrastructure. ArcLight applies an operationally intensive investment approach that leverages the firm’s deep experience managing physical assets across the entire power value chain. The fund targets opportunities created by tightening power markets, the large-scale electrification megatrend, increased penetration of variable renewable energy, and the growing energy and infrastructure needs of the digital economy, including data centers and artificial intelligence compute requirements. Geographically, Fund VIII focuses on North America, covering the United States, Canada, Central America, and the Caribbean.

ArcLight Capital Partners has managed approximately 70 GW of power generation assets and 48,000 miles of transmission infrastructure representing more than $80 billion in enterprise value since its inception in 2001. The firm raised over $6 billion across all vehicles in the 24 months preceding Fund VIII’s close. Fund VIII continues ArcLight’s 25-year tradition of identifying and managing operationally intensive infrastructure assets, positioning the fund to capitalize on the ongoing transformation of the North American power sector.
