Methodology — Gas Exposure Score

The Gas Exposure Score (0–100) measures structural vulnerability to gas price volatility:

Gas Exposure Score = (Gas Generation % × 0.50) + (Spot Purchase % × 0.50)

High Risk = above median exposure AND spot % ≥ 50%. Managed Risk = high gas generation but low spot. Moderate Risk = low gas but high spot. Low Risk = below median on both. ConEd generates 100% from gas but buys it all on fixed contracts — managed risk. Mississippi Power buys 100% at spot with 91% gas — maximum structural exposure.
