Frigid temperatures and heavy precipitation on the West Coast drove spot natural gas prices to historic highs, with Northern California reaching $55/MMBtu. Storage inventories were low, drought cut hydroelectric output, and regional utilities had trouble receiving coal deliveries.
Prices reached levels not seen since summer 2018.
Low storage combined with drought-reduced hydro and coal supply makes regional gas balances very tight, pushing prices sharply higher. The spike highlights how regional shortages can quickly lift gas costs for power generation and industrial users.
After 221 past bullish weather events, Natural Gas moved a median +3.3% over 5 sessions (61% higher; middle half -5.2% to +14.0%), and -0.3% over 20.
