NextEra Energy and Dominion Energy are merging to create the world's largest electric utility, valued at US$420bn, amid surging AI data centre power demand

When two giants of an industry come together for a merger, the world takes notice. When that combined entity promises to be the largest a sector has ever seen, the world stops in its tracks.

Think Vodafone and Mannesmann, Exxon and Mobil, even the proposed merger between Warner Bros and Paramount that is under negotiation today. These kinds of deals have the capacity to entirely reshape an industry.

This is exactly what is happening now in American utilities.

NextEra Energy, already the world's largest utility by market cap, is set to acquire its US rival Dominion in a deal that experts say will create the world's largest electric utility.
