Denominator: 15

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 complete quantity below the fraction bar; it must be nonzero for this division.

Its job in the formula

15 occurs below the fraction bar. The quantity above the bar is divided by this expression; zero is excluded as a denominator.

The passage around this formula

…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 reporting below, lists 27 turbines totaling roughly 495 megawatts — 495 divided by 27 is about 18.3…
