Trade Policy and Tariffs

DOMINION ENERGY, INC · 2026-10-30 · Importance 26 · Surprise 24

Dominion Energy estimates that tariffs increase the CVOW Commercial Project’s expected total cost by a net $0.1 billion relative to Virginia Power’s January 2026 construction update. Revised Section 232 tariffs enacted in April 2026 account for an approximately $0.2 billion increase on equipment containing steel, aluminum or copper expected to be delivered from April 2026 through 2027. That increase is partly offset by reversals and other adjustments related to tariffs on equipment originating from Mexico, Canada, the European Union and other applicable countries. Actual tariff costs depend on the requirements and rates in effect when specific components are delivered.
