How to read risk indicators, confidence levels, trend analysis, and primary drivers across all 8 monitored Texas cities.
The Texas Grid Map shows real-time operational risk for each of the 8 monitored cities. Each city card displays four key indicators:
Risk Level
Low / Medium / High — the composite risk score for that city based on weather, ERCOT pricing, and gas supply signals.
Risk Direction
Whether conditions are escalating, stable, or improving. An upward arrow indicates building pressure even at the same risk level.
Primary Driver
The dominant factor driving the current risk score — typically Weather Demand, ERCOT Pricing, or Gas Supply.
Confidence
Data freshness for that city's signal set. Cities with fresh NOAA data and recent ERCOT readings show higher confidence.
At the top of the Grid Map, the Statewide Summary aggregates conditions across all 8 cities:
High Risk Count
Number of cities currently at High risk. Two or more cities at High risk signals a broad state-wide event — not a localized condition.
Statewide Status
A roll-up status: Elevated (2+ cities High), Watch (1 city High or 2+ Medium), or Normal.
Worst Location
The city with the most severe current conditions. Use this to focus your monitoring attention during complex events.
Texas's largest energy market. Highest demand density. Primary benchmark for ERCOT HB_HOUSTON pricing. Summer heat events in Houston drive state-wide grid stress.
Second-largest Texas energy market. North zone pricing can diverge from Houston during transmission constraint events. Industrial and commercial load concentration.
South zone. Moderate demand. State capital with growing data center and tech sector load. Weather patterns differ from coastal cities.
South zone alongside Austin. Military and industrial load base. Extreme summer heat events can create localized demand spikes.
Permian Basin hub. Oil and gas operational load dominates. LZ_WEST pricing affected by transmission constraints and high wind generation output from West Texas.
Permian Basin operations center. Similar exposure to Midland. Waha Hub natural gas pricing is more relevant than Henry Hub for direct gas users in this zone.
Coastal location. Petrochemical and refining complex creates significant industrial load. Gulf weather patterns create distinct risk profiles from inland cities.
West Texas. High proximity to wind generation. LZ_WEST prices can see large negative swings during high wind / low demand periods — a cost opportunity for flexible load operators.
