Williams, a major natural gas infrastructure company, is turning to some of the biggest names in private equity to help finance a wave of new power plants designed to serve the booming energy needs of artificial intelligence and data centers. The company announced it is selling a 49% noncontrolling stake in five behind-the-meter generation projects to investment vehicles managed by Blackstone, Apollo, and KKR for $5.34 billion.
The deal allows Williams to retain operational control of the projects while freeing up capital that can be reinvested in further expansion. It is the latest sign that the financial firepower of private markets is being deployed to solve one of the most pressing infrastructure challenges of the AI era: where to get enough reliable electricity.
What Are Behind-the-Meter Generation Projects?
Behind-the-meter generation refers to power plants built on the same site as a large electricity consumer—such as a data center or industrial facility—that can supply power directly without relying entirely on the local grid. This setup can offer greater reliability and faster deployment than waiting for new transmission lines or grid upgrades.
For AI and data center operators, the appeal is clear. Training and running large language models requires enormous amounts of electricity, and the existing grid in many regions is already strained. Behind-the-meter projects can bypass some of those bottlenecks, but they are also capital-intensive, often costing hundreds of millions or billions of dollars each.
That is where partners like Blackstone, Apollo, and KKR come in. By selling a minority stake, Williams can share the financial burden while keeping strategic control. The structure is similar to what other energy and infrastructure companies have used to fund large projects without taking on excessive debt or diluting existing shareholders.
Why This Matters for Investors
For everyday investors, this deal highlights a broader trend: the intersection of AI and energy is creating new opportunities—and new risks—across multiple sectors. Companies that own or build power infrastructure are seeing increased demand, but they also face high upfront costs. Partnerships with private equity can help bridge that gap.
Williams is not alone in this approach. Other energy firms are also teaming up with private capital to fund AI-related power projects. For example, Matinas BioPharma recently ditched biotech for nuclear power in a merger with GH Power, and Holtec Nuclear filed for an IPO as investor interest in atomic power surged. These moves reflect a growing recognition that AI's energy demands will require a mix of natural gas, nuclear, and renewables.
Investors should also note the involvement of Apollo, which has been active in dealmaking across sectors. The firm recently made headlines with a £7.65 billion bid for EasyJet and a €3 billion deal with Bayer, showing its appetite for large, complex transactions. Its participation in the Williams deal underscores the scale of capital flowing into AI infrastructure.
What to Watch Next
The $5.34 billion deal is a significant sum, but it represents only a fraction of the total investment needed to meet projected AI power demand. Analysts expect more such partnerships in the coming months, as utilities and independent power producers seek to finance new generation capacity.
For Williams, the deal provides a financial cushion and a vote of confidence from sophisticated investors. The company will need to execute on the construction and operation of the five projects, while also managing the regulatory and environmental challenges that come with building new power plants.
For the broader market, the deal reinforces the idea that AI is not just a tech story—it is an energy story. Companies that can deliver reliable, affordable power to data centers are likely to see sustained demand, even if the path to profitability is not always straightforward.
As always, investors should consider their own risk tolerance and diversification. The energy sector can be volatile, and AI-related demand may not materialize as quickly as some expect. But for those looking to understand where the money is flowing, the Williams-Blackstone-Apollo-KKR deal is a clear signal that private capital is betting big on AI power.
