Founded in 2001, ArcLight is an established leader in managing and operating electric power, renewable, and strategic gas infrastructure. These infrastructure segments sit at the epicenter of the energy transition and are indispensable to powering the data centers driving our digital economy.
We believe our investment strategy is aligned with the mega-trends that we believe will define the infrastructure landscape over the coming decades. These trends include: (a) tightening power markets driven by electrification and data center demand growth; (b) increasing renewables and battery storage penetration requiring more operationally intensive, market-oriented management; (c) the long-term role of natural gas transmission, storage and LNG infrastructure in the transition; (d) the growing premium for strategic hard assets that offer operational performance and reliability and provide critical entitlements for new infrastructure deployments; and (e) the massive energy and infrastructure needs of the digital economy.
