How the score is calculated: The Texas Grid Index combines three ERCOT signals — ERCOT's own energy level value (60%), system reserve margin (25%), and physical responsive capability in MW (15%). EEA emergency declarations override the computed score floor. Updated every 15 minutes from public ERCOT data.
