Western Price Survey
February 12, 2016
Prices for Southern California natural gas futures trended higher than benchmark Henry Hub prices as a result of the just-stopped gas leak at Southern California Gas Co.'s Aliso Canyon storage facility.
The 28 cent/MMBtu premium for winter SoCal natural gas compared to Henry Hub is the result of reliability concerns, according to Barclays, with January and February 2017 futures trading at 50 cents/MMBtu greater than the Henry Hub price. Analysts expect "increased demand for exports to Mexico at the southern border and declining production levels out of the San Juan basin" to support the trend.
The question is whether California natural gas in storage is adequate to meet next year's peak heating demand. Statewide storage is at about 90 percent of capacity as of November, but the figure may be lower given mandatory withdrawals from Aliso.
In the months ahead, hydro and continued solar generation should keep more natural gas in storage for next winter. Solar power accounted for roughly 8 percent of the state's power generation in 2015; an additional 2.4 GW of solar power is expected to come on line before year's end. Wetter weather and a stronger snow-pack should bolster hydro's contribution this summer, according to Barclays.
The California snow-water equivalent measured 20.4 inches, or 73 percent of the April 1 average, as of Feb. 11, according to the California Department of Water Resources.

In the Feb. 12 Western Price Survey, we incorrectly identified the owner of the Aliso Canyon natural gas storage facility. It is Southern California Gas Co. We regret the error.
