The pin starts at the first Epoch[1][2] AI satellite reading of land clearing (28 Feb 2025); SemiAnalysis[8] dates the project kickoff to the 7 Mar 2025 site purchase. The end date is Epoch AI’s projected completion of Building 3 (25 Feb 2027), a projection rather than a developer commitment. Power-plant and turbine-removal targets (Q2 2027, July 2027) are listed as separate planned milestones.
xAI’s Colossus 2 in Whitehaven, Memphis is a gigawatt-class AI data center that Epoch AI tracks at 946 MW of IT power and about 1,112k H100-equivalents, still expanding toward a projected 1,531 MW by February 2027. It is powered by gas turbines at a former Duke Energy plant across the state line in Southaven, Mississippi, where 41 permanent turbines were permitted in March 2026 and temporary units are due to be removed by July 2027. The build has drawn a NAACP Clean Air Act lawsuit and neighbors’ noise complaints, and support from Southaven’s mayor and xAI, which cites thousands of jobs.
