Time Period2019–2022
Flagship EventFebruary 2021 Texas freeze (prices spiked 100× at some hubs)

Causal Reasoning Model

Three diagnostic pathways trace price anomalies to their root causes:

1. Weather Extremes: polar vortex → heating demand surge → price spike 2. Pipeline Constraints: hub spread divergence reveals supply bottlenecks 3. Supply Disruption: production freeze-offs during extreme cold

The Texas Freeze

The February 2021 event is the flagship diagnostic case: extreme cold knocked out gas production across Texas, demand for heating surged simultaneously, and prices spiked 100× at some hubs, a perfect storm traced through all three causal pathways.
