Dominion data-center contracted capacity, July 2023 to July 2026

Dominion's data-center contracts grew from 16.5 GW in July 2023 to 53.8 GW in July 2026. The steepest stretch was July to December 2024, when the total rose 18.8 GW and 18.6 GW of that was engineering letters, the earliest of the three authorization stages and the furthest from a meter. This is contracted pipeline capacity, a different quantity from the large-load request queue, and neither is energized load.

Stacked area chart of Dominion Energy Virginia data-center contracted capacity across eight observations from July 2023 to July 2026, split into service agreements, construction letters, and engineering letters. The total grows from 16.5 GW to 53.8 GW. Between July and December 2024 the total rises 18.8 GW, almost entirely in the engineering-letter band, while the service-agreement and construction-letter bands stay nearly flat.

This figure is from the Dominion Virginia case study, a primary-source reconstruction of how data-center growth shows up on residential bills.
