Regulatory Risk

DOMINION ENERGY, INC · 2026-10-30 · Importance 44 · Surprise 60

In September 2026, the EPA finalized a rule repealing the majority of its May 2024 package of rules governing carbon dioxide emissions from certain fossil fuel-fired electric generating units. The 2024 package included standards for new and reconstructed gas-fired combustion turbines and modified coal-fired units, as well as emission guidelines for existing coal-, oil- and gas-fired steam units. Dominion Energy says it cannot yet predict the effects of pending proposed rulemakings until the EPA takes final action and publishes the rules. The effects could materially affect the company’s financial condition and cash flows.
