How to read this: Each line shows how a non-weather factor changes
gas burn in the power sector, in MMcf/d. Negative = the factor is
pushing gas burn down (e.g., wind is generating). Positive = pushing
gas burn up (e.g., nuclear outage forcing gas to fill in). The orange line is the
net of all five.
Method: wind/solar impact = -generation × 8.0 MMBtu/MWh ÷ 1.029. Hydro/nuclear/coal impact = -(today's generation − 365-day trailing avg) × 8.0 ÷ 1.029.
Method: wind/solar impact = -generation × 8.0 MMBtu/MWh ÷ 1.029. Hydro/nuclear/coal impact = -(today's generation − 365-day trailing avg) × 8.0 ÷ 1.029.

Daily impact on power-sector gas burn — US Total (sum of 7 ISOs)
Wind/solar shown vs a zero-resource counterfactual (true displacement). Hydro/nuclear/coal shown as output vs their own trailing-year averages (performance indicators, not displacement claims). The "Illustrative Sum" combines these mixed methodologies and should be read as directional, not precise.
Positive = more gas burned (nuclear outage, coal-to-gas switching).
