What does this equation mean?

The site did not stay at 150 megawatts. By the account maintained by the nonprofit research group Global Energy Monitor, which tracks power-generating assets from public filings and satellite imagery, Colossus 1’s Unit 1 carries an official capacity of 198 megawatts, and the Shelby County Health Department’s air permit — the subject of the next section — authorizes turbines capable of roughly 247.2 megawatts combined [ 6 ] . A second small equation falls directly out of that filing: the permit covers 15 Solar SMT-130 turbine units for a combined 247.2 megawatts, implying an average unit rating of $\bar{P}_{\mathrm{turbine}} = \frac{247.2\ \mathrm{MW}}{15} \approx 16.5\ \mathrm{MW\ per\ unit}$. The Southaven site’s later authorization, covered in the DOJ-intervention reporting below, lists 27 turbines totaling roughly 495 megawatts — 495 divided by 27 is about 18.3 megawatts per unit, a broadly similar class of mobile turbine, though the two filings may not describe identical hardware and the comparison should be read as illustrative rather than exact [ 10 ] . The arithmetic’s real point is structural: once a training cluster crosses roughly 100,000 accelerators, the constraint that actually shapes the build is no longer chip supply. It is how many tens of megawatts a distribution utility can add to one site on a timeline measured in months rather than the multi-year interval a permanent transmission upgrade requires — which is precisely why a site like this leans on truck-delivered mobile turbines instead of waiting on the grid.
