AI fuels record $200bn M&A boom in US power sector

U.S. power and utility dealmaking has surged to a record as AI-related electricity demand pushes companies, investors and regulators into a faster-moving contest over scale, generation and grid infrastructure.

According to the Financial Times, announced U.S. power and utility mergers and acquisitions reached $203.6 billion in the first five months of 2026, more than 40% above the $141.7 billion recorded in all of 2025. The paper said the surge is being driven in part by the rapid buildout of data centers for artificial intelligence, which is increasing pressure on utilities to expand supply and transmission capacity.

The FT also said investment in data centers reached $151.5 billion in the first five months of 2026, up from $68.7 billion a year earlier, after total data-center investment hit $321 billion in 2025. That spending wave has made electricity availability a central strategic issue for utilities, infrastructure investors and large technology customers.

The record deal wave

The FT said there were 77 power and utility deals announced in the first five months of 2026, compared with 157 for all of 2025. The value is being driven by a small number of very large transactions rather than a broad jump in deal count, underscoring how quickly capital is concentrating around the sector’s biggest regulated assets.

The largest power and utility transaction announced this year, according to the FT, is NextEra Energy’s proposed takeover of Dominion Energy, with an enterprise value of $112 billion. The second-largest cited deal is BlackRock Global Infrastructure Partners and EQT’s purchase of AES Corp, with an enterprise value of $33 billion.

Earlier reporting in May described the NextEra-Dominion transaction as a $67 billion all-stock deal. That figure reflects a different valuation measure, rather than a direct contradiction. The Guardian said the combination would create the world’s largest regulated utility if approved, serving about 10 million customer accounts.

Why utilities want scale

The business logic behind the wave is straightforward. Utilities need huge amounts of capital for power plants, transmission lines and other infrastructure that can support rising load from data centers and broader electrification. Bigger balance sheets can make that financing easier and, supporters argue, may lower borrowing costs.

That is one reason infrastructure investors and private equity groups are active in the sector. Regulated utilities and grid assets can offer stable cash flows, while consolidation can create larger platforms positioned to serve heavy industrial and technology demand.

FT’s reporting also said utility companies are arguing that being bigger can lower financing costs and potentially reduce consumer electricity prices. Critics, by contrast, warn that larger monopolies could gain too much power over pricing and reduce competitive pressure in markets that are already tightly regulated.

Customer and regulatory stakes

The consumer angle is now central to the debate. The Guardian reported that NextEra and Dominion promised $2.25 billion in bill credits over two years after closing. Axios said local officials and ratepayer advocates remain focused on whether promised protections will hold up over time.

The regulatory challenge is especially significant because utilities are monopoly businesses in many states. Any large combination must clear state and federal review, and regulators are likely to test whether projected efficiencies really flow through to customer bills rather than just to shareholder returns.

The deal wave also raises a broader public-policy question: whether AI-driven load growth is helping justify mergers that would have been harder to sell in a slower-demand environment. If utility executives can tie consolidation to the need to fund new generation and transmission for data centers, the rationale for scale becomes more persuasive to investors, even if it remains controversial for consumers.

What to watch next

The next phase of the story will turn on filings, approval conditions and any changes to deal terms. The NextEra-Dominion transaction will be the key test case, and the AES acquisition will also be watched for timing and disclosure updates.

Investors and policymakers will be looking for more utilities to cite AI and data-center demand as a reason for consolidation. If that pattern continues, the current record could mark the start of a longer restructuring cycle in the U.S. power sector rather than a one-off spike.

For now, the message from the market is clear: AI is not only reshaping software and semiconductors. It is also reshaping who owns the wires, plants and regulated assets that keep the grid running.
