Docket No. 2026-186-EG Why is this Notice Important? • On July 15, 2026, Dominion Energy South Carolina, Inc. (“DESC”), Dominion Energy, Inc. (“Dominion”), and NextEra Energy, Inc. (“NextEra”), (together, “Joint Petitioners”) filed a Joint Petition for review and approval of a proposed business combination between Dominion and NextEra related to a transfer of control of DESC resulting from the merger of Dominion with NextEra (the “Merger”). • If the Merger is approved, DESC will become an indirect wholly-owned subsidiary of NextEra. • The Joint Petitioners are requesting regulatory approval from the Public Service Commission of South Carolina (“Commission”). • The Joint Petitioners are also requesting regulatory approval in other jurisdictions such as the Virginia State Corporation Commission, the North Carolina Utilities Commission, the Federal Energy Regulatory Commission, and the United States Nuclear Regulatory Commission. If all regulatory approvals are received, the Joint Petitioners anticipate closing of the Merger in the second half of 2027. Will DESC’s Customers’ bills be impacted if the business combination (or Merger) is approved? • According to the Joint Petition, the Joint Petitioners propose issuing customer bill credits (or rate credits) over a two-year period to DESC’s electric and natural gas customers following the Merger’s closing. • Bill credits (or rate credits) are based on South Carolina’s pro rata share of 2025 total electric energy sales. • The individual customer rate credit amounts will be calculated annually based on the customer’s historic consumption during the prior calendar year. • The credit allocation is designed for the residential electric customer class to deliver a $10 per month credit over the two-year credit period for a typical residential customer utilizing 1,000 kWh of electricity per month. The amount to each electric customer will vary by actual usage. The bill credit will appear as a separate line item on the electric customer bill. • For natural gas customers, individual credits will be calculated twice over a two-year period following the closing of the merger, and DESC’s natural gas customers will receive a single bill credit that will appear as a separate line item on the natural gas customer bill. The case was filed according to S.C. Code Ann. § 58-27-1300 and other applicable law and the hearing is scheduled pursuant to Directive Order No. 2026-422 and S.C. Code Ann. Regs. 103-817.
