How the time-to-power window was estimated

Evidence used

Current stage: Operational (furthest stage with documented evidence)[1]
Stated date: Next projected milestone: 2028-01-01 (modeled/speculative)[1]
Required: 487 MW

Assumptions

From “Under construction”, large loads have typically taken 0.5–2 more years to first power (editorial range; see Methodology).
The window is a range of plausible outcomes under these assumptions, not a forecast. It moves as new filings, queue updates or imagery arrive.

Window: H2 2027 – H2 2028

Utility & rates1

GS-5 rate class for customers demanding 25 MW or more[13]ConfirmedBacked by a filing, deed, permit, interconnection-queue record, or a government or utility record. As of Nov 25, 2025.Nov 25, 2025
Dominion Energy · Virginia State Corporation Commission · Docket PUR-2025-00058 · Final order issued · effective Jan 1, 2027
“the new GS-5 rate class will comprise customers demanding 25 megawatts or more. The new rate class will be effective beginning January 1, 2027.”
Applies to Dominion Energy Virginia's service territory; the facility's utility is the most likely retail provider by location unless a source names it.

Utility, ISO and nearby assets are derived from the site's location. Proximity to a substation or line doesn't establish the interconnection; that needs a utility filing or interconnection-queue record. Queue requests are applications, not commitments — most never reach operation.

Timeline

Construction start: Oct 19, 2019[1]

First operational: Oct 1, 2024[1]

Oct 19, 2019[1]
Land clearing begins by Peterson Companies for Stack Infrastructure, which is noted in the news and visible on satellite imagery.
Oct 1, 2024118 MW facility power· 1 buildings operational[1]
Building 1 is operational, which is assumed to be three months after the last backup diesel generators are finished. The generators were first seen to be finished July 1 from satellite imagery (a clear image of this can be seen on July 29 via Google Earth).
Feb 14, 2026118 MW facility power· 1 buildings operational[1]
All buildings have begun construction (with groundwork starting for AI building 6), as depicted by satellite imagery.
Jan 1, 2028Projected487 MW facility power· 6 buildings operational[1]
Estimate: All 6 AI data center buildings will be finished in 2028, assuming a groundbreak-to-operational timeline of 18-24 months. One is complete, three are clearly under construction, and the last two data centers are still breaking ground and laying foundations.
