US utility giant NextEra Energy #NEE# is reportedly in talks to combine with rival Dominion Energy #D# in a deal that could create a $400 billion power company as surging electricity demand from AI data centers reshapes the U.S. energy landscape. According to a report by the Financial Times on Friday, the talks could result in one of the largest mergers in corporate history and may be announced as soon as next week. The discussions are ongoing and could still collapse, the report said, adding that the transaction is expected to be structured largely as a stock deal.
