How the time-to-power window was estimated

Evidence used

Current stage: Operational (furthest stage with documented evidence)[1][3]
Stated date: Next projected milestone: 2027-02-20 (modeled/speculative)[1]
Required: 2.72 GW

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: H1 2027 – H2 2028

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: Jul 14, 2023[1]

First operational: Apr 2026[3]

Jul 14, 2023[1]
Land clearing begins for Building 1.
Sep 26, 2025[1]
Building 1 cooling and backup generators all look complete from above but there is still construction visible around the building. Building 2 is well underway with a foundation and a complete substation. Large carpark and concrete area north of Building 2. Building 3 has a concrete foundation and a substation underway.
Jan 28, 2026[1]
Building 1 looks complete, but based on Microsoft announcements, it's not fully operational yet. Steel framing is underway for Building 2.
Apr 16, 2026442 MW facility power· 1 buildings operational[1]
Building 1 is operational. X post from Microsoft saying this date for Fairwater becoming operational.
May 15, 2026442 MW facility power· 1 buildings operational[1]
The main shell of Building 2 looks almost completed. In Area 2 (northwest of Buildings 1-2), the grading for the original design has been replaced with grading for the new 9-building design, making way for Buildings 3-11. Work continues on the northern substation in Area 2.
Feb 20, 2027Projected885 MW facility power· 2 buildings operational[1]
Building 2 is operational. This is estimated based on (1) the delay between Building 1 and Building 2 starting land clearing, (2) in March 2025, a Microsoft spokesperson said “fully on track” with the first phase , where “southern datacenter buildings complete, and preparation begins for operations” was expected by late 2026. Finally, while it's not 100% consistent with our estimates, MISO was planning 1480 MW of load for Microsoft in Mount Pleasant in 2026.
May 13, 2028Projected2.72 GW facility power· 11 buildings operational[1]
Buildings 3-11 are estimated to be operational. The grading for this revised 9-building plan was underway in May 2026, and we assume an average 2-year build time from that point.
