subscript

Pˉturbine=247.2 MW15≈16.5 MW per unit.\bar{P}_{\mathrm{turbine}} = \frac{247.2\ \mathrm{MW}}{15} \approx 16.5\ \mathrm{MW\ per\ unit}.

What this part means

The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.

Its job in the formula

A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula

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 Pˉturbine=247.2 MW15≈16.5 MW per unit\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…
