LS Power Closes Fund VI at $6 Billion, 50% Above Its $4 Billion Target

LS Power announced on 6 October 2026 that it has closed LS Power Equity Partners VI, known as Fund VI, at $6 billion in total commitments. The target was $4 billion, so the fund finished 50% above it. Fund V raised $2.7 billion in 2024, which makes Fund VI about 2.2 times the size of its predecessor, or 122% larger. The fund launched in January 2026 and was fully allocated by July, so the raise took roughly six months. It will invest in renewables, conventional generation, energy storage, distributed energy and related power infrastructure in North America.

What the close shows

About $1.7 billion is already committed to pending acquisitions of a 5 GW gas-fired generation platform from Constellation Energy across the PJM and ERCOT power markets. Those deals have not closed. LS Power says it has now raised about $19.8 billion in equity commitments across its flagship funds since inception, so Fund VI alone is roughly 30% of that total.

The investor base is broad: pensions, insurers, sovereign wealth funds, asset managers, foundations, endowments, family offices and private wealth investors, including investors in markets new to the firm. That is eight investor types in one fund. The firm did not publish a split by capital or by count, so we cannot say which type contributed the most.

Who is behind it

Two public pensions disclosed their commitments earlier this year. The Washington State Investment Board committed $300 million and the Virginia Retirement System committed $200 million. Together that is $500 million, or 8.3% of the final fund by capital. Two named pensions out of an unknown number of investors cannot give a share by count, so treat the 8.3% as the disclosed floor and not the whole picture.

What GPs can take from it

This section is our reading and not a statement from the firm. A power fund that raised 50% more than its original ask in about six months shows that LPs are writing large cheques for energy infrastructure that comes with a clear acquisition pipeline. For comparison, Audax closed a $5.4 billion fund at its hard cap last week, so oversubscribed final closes are not confined to one strategy. Large LPs are also taking direct infrastructure positions, as in CPP Investments' fiber venture announced the same day.

For a manager raising an infrastructure or energy fund, the practical lesson is to show a named pipeline early. The $1.7 billion already committed is the kind of evidence that lets an LP underwrite a blind-pool fund. With sovereign wealth funds among the investors, it is worth widening the target list beyond the usual pensions.

What to watch next

Watch for completion of the Constellation acquisitions, which depend on regulatory approvals, and for any LP disclosures that put names and amounts to the rest of the $6 billion. FundLinx members can see who is allocating to power and infrastructure.
