About

ArcLight

ArcLight is a leading infrastructure investor with a long-standing focus on critical electrification infrastructure since its founding in 2001. ArcLight has owned over 65 GW of power and 47,000 miles of electric and gas transmission infrastructure, representing over $80 billion in enterprise value. ArcLight has a proven history of value-added investing across its core investment sectors including power, hydro, solar, wind, battery storage, electric transmission and natural gas transmission and storage infrastructure.  ArcLight’s team employs an operationally intensive investment approach that benefits from its dedicated in-house strategic, technical, operational, and commercial specialists, as well as the firm’s ~2,000-person asset management partner.

We believe our extensive experience, deep domain expertise, and specialist resources enable us to source innovative transaction opportunities, deliver value-enhancing commercial and operational solutions, and unlock decarbonizing energy transition opportunities via asset re-positioning. Our strategic focus is on cash generative real assets positioned to capitalize on what we believe are the long-term industry tailwinds of electrification, decarbonization, and powering the digital economy. 

Corporate Social Responsibility

Making a positive impact in our communities continues to be part of our approach to operating responsibly. Over the years, our Boston-based team has formed relationships with several local organizations that focus on addressing a variety of unmet needs in our communities. We have supported these organizations with time and resources and are proud of the long-lasting and personal relationships that have grown from our engagement. As part of that effort, both ArcLight and our employees provide time and capital to these important organizations:
