Which energy company’s natural gas assets did Berkshire Hathaway acquire in 2020? The seller was Dominion Energy.

Berkshire Hathaway Energy agreed in July 2020 to acquire substantially all of Dominion Energy’s gas transmission and storage business. The transaction included thousands of miles of natural-gas pipelines, storage facilities, and related interests. It was completed in stages, with the main purchase closing on November 1, 2020.

The deal was valued at roughly $9.7 billion when announced, including about $4 billion in cash and the assumption of approximately $5.7 billion in debt. After the transaction, the acquired operations became part of Berkshire Hathaway Energy’s gas-transmission and storage portfolio.

A common mix-up is to name another large utility such as Duke Energy or NextEra. Those companies were not the seller in this transaction. The deal also did not represent Berkshire buying all of Dominion Energy: it was a purchase of most of Dominion’s gas transmission and storage assets, while Dominion retained other regulated utility businesses.
