LS Power, a privately held North American power infrastructure developer and investor based in Manhattan, has raised $6 billion for LS Power Equity Partners VI, topping an initial $4 billion goal. The new vehicle is larger than the prior fund, which collected $2.7 billion in 2024. Investors included public-employee retirement plans, insurers, sovereign wealth vehicles, money managers, family-office capital, and additional limited partners. Across six funds, the firm has gathered about $13 billion so far.
Nearly a third of the new fund has already been deployed. About $1.7 billion went in March toward buying natural gas powered assets from Constellation Energy Corp. In total, LS Power has agreed to acquire about $5 billion of US electric generation assets from Constellation as part of mandated divestitures following the US power company's high-profile purchase of Calpine Corp. The fund plans to put money into gas-fired generation, clean-energy projects, battery storage, distributed resources spread across the grid, and potentially other essential energy infrastructure.
Power generation has quietly become one of the hottest places to put capital. Market Briefs covers the energy build-out free every weekday.
Electricity demand is ramping up alongside artificial intelligence, and the aging US grid is feeling the strain. Existing power plants have grown more valuable as supply chain bottlenecks and long construction timelines make quick additions to capacity tough. "It's a capital-intensive business, and the opportunity set has never been bigger," said Chief Operating Officer Darpan Kapadia, who added, "I think most of the capital we deploy will be into operating projects." He also noted, "Power demand is growing at rates that we haven't seen for decades," and pointed out that data center needs can arrive in 12 to 16 months while new supply can take more than five years, "so you have this mismatch."
In January, LS Power divested a portfolio of natural gas plants to NRG Energy Inc., a transaction worth $12 billion.
If you care about where real-world cash is moving, here it is: investors are writing big checks for operating power assets because new plants take years to build. That tilt toward existing generation, plus a mix of gas, renewables, storage and smaller resources across the grid, is a tell on how capital is positioning for tight electricity markets and fast-growing data demand.
