Southern California Edison must charge customers an extra $815 million after failing to anticipate a July heat wave that sent regional gas prices to a record. Gas for Los Angeles delivery traded at almost 10 times the US benchmark in early February, amid pipeline outages and restrictions on the Aliso Canyon storage field.
Pipeline outages and storage limits leave Southern California exposed to price spikes whenever temperatures swing. The regional tightness can lift gas and power costs in a major demand center.
After 54 past bullish logistics events, Natural Gas moved a median -1.8% over 5 sessions (43% higher; middle half -5.7% to +6.2%), and +5.1% over 20.
