RICHMOND, Va., June 30, 2023 /PRNewswire/ -- Dominion Energy (NYSE:D) has updated its second-quarter operating earnings guidance range to $0.44 to $0.50 per share. The revised guidance reflects the estimated impact of historically mild weather, unplanned outages at the Millstone Power Station, and positive factors such as lower costs. The original second-quarter guidance range was $0.58 to $0.68 per share.

Given the pending business review, the company has not provided full-year 2023 earnings guidance. The company plans to host an investor event in the third quarter, during which it will provide an updated strategic and financial outlook based on the results of the business review, which is still underway.

Updated operating earnings guidance drivers

Extremely mild weather in the company's electric service territories, relative to 15-year normal, is expected to negatively impact second-quarter operating earnings by $0.07 to $0.09 per share. Second-quarter weather is currently expected to be the mildest relative to normal over the last 50 years.

On April 6, 2023, Millstone Power Station Unit 2 entered a planned refueling outage. The outage lasted longer than expected due to additional work identified during the outage to ensure the unit will run reliably for the next operating cycle. All necessary work has been completed, and the unit is in the process of returning to service.

On May 30, 2023, Millstone Power Station Unit 3 had an automatic reactor trip due to a turbine trip caused by electrical protection. All systems responded as expected to the trip, and all necessary work has been completed. The unit returned to service on June 29, 2023.

Millstone Power Station has a strong history of exemplary performance, in both safety and reliability. It is the largest carbon-free generating facility in New England. For the past two decades, it has provided reliable and affordable power to New England consumers on the hottest and coldest days. That is why the company worked efficiently to resolve issues impacting reliability, consistent with the high standards of the company's nuclear operations.

Important note to investors regarding operating, reported earnings

Dominion Energy uses operating earnings (non-GAAP) as the primary performance measurement of its earnings guidance and results for public communications with analysts and investors. Operating earnings are defined as reported earnings adjusted for certain items. Dominion Energy also uses operating earnings internally for budgeting, for reporting to the Board of Directors, for the company's incentive compensation plans, and for its targeted dividend payouts and other purposes. Dominion Energy management believes operating earnings provide a more meaningful representation of the company's fundamental earnings power.

In providing its operating earnings guidance, the company notes that there could be differences between expected reported earnings and estimated operating earnings for matters such as, but not limited to, the mark-to-market impact of economic hedging activities, gains and losses on nuclear decommissioning trust funds, acquisitions, divestitures or extreme weather events and other natural disasters. Dominion Energy management is not able to estimate the aggregate impact of these items on future period reported earnings.
