How Does Dominion Energy Make Money?
Dominion Energy Virginia supplies 72% of revenue, so Dominion Energy's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Corporate and Other grew fastest (+39.4%) and Contracted Energy slowest (+6.3%), so the revenue mix tilts toward Corporate and Other while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Dominion Energy Virginia | $11.8 billion | $10.2 billion | 71.7% | 15.7% |
| Dominion Energy South Carolina | $3.6 billion | $3.3 billion | 21.7% | 8.3% |
| Contracted Energy | $1.2 billion | $1.1 billion | 7.1% | 6.3% |
| Corporate and Other | $1.2 billion | $841 million | 7.1% | 39.4% |
What the Segment Figures Do Not Show
The rows above add up to 108% of Dominion Energy's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value Dominion Energy reported in the segment note and revenue disclosures of its Form 10-K filed February 23, 2026 (accession 0001193125-26-063120), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
