The source cooling surge is nominal one hundred fourteen point six times multiplier minus one times positive temperature surge divided by eighteen. At assumed temperature surge eighteen, multipliers one point two five and one point five give twenty-eight point six five and fifty-seven point three gigawatts. Bars share six pixels per gigawatt. This is an uncalibrated demand expression, not observed power-system telemetry. The source available capacity is base capacity times one minus offline percentage divided by one hundred. Hypothetical base one hundred gigawatts with ten and twenty percent offline gives ninety and eighty gigawatts. Bars share four pixels per gigawatt. The calculation does not verify actual maintenance availability or grid adequacy. The source net demand is the maximum of seventy and gross demand minus active demand response. Illustrative raw differences sixty-five and ninety-five therefore display seventy and ninety-five gigawatts before one-decimal telemetry rounding. Bars share four pixels per gigawatt. The floor is a source modeling bound, not a universal physical limit. Complete actual audit JSON, genuine default preset, native responsive allocation and first-footer preservation remain checked.
