With Aliso Canyon natural gas storage at capacity and the Honor Rancho storage facility shut in for maintenance, Southern California Gas Co.'s ability to use storage injections for system balancing is limited, with supply excesses expected into the week of Oct. 25.
Western natural gas system constraints throttled flows into the Pacific Northwest from Canada between Oct. 7 and Oct. 14, while demand effects rippled throughout the Southwest into Southern California.
The shut-in of the Aliso Canyon natural gas storage facility continued supporting Western energy prices. Both natural gas and power prices generally ended higher at the end of Sept. 30 to Oct. 7 trading.
Ongoing regional pipeline constraints, cooler temperatures and the shut-in of Aliso Canyon natural gas storage contributed to Western natural gas prices generally above $5/MMBtu.
California natural gas values continue to be pressured not only by transmission constraints that are expected to continue indefinitely, but also by new supply disruptions.
As weather conditions across the Western U.S. moderated, so too did most regional energy prices; however, transmission derates were a significant factor that supported prices for a few days during the week.
A lull in the extreme heat across the West suppressed regional power prices this week, but might be a preview of upcoming demand and pricing patterns, especially in the desert Southwest.
Extreme, record heat across the West triggered demand that pushed power prices to extremes, the most obvious of which was the 6,000-percent leap in Palo Verde daytime power between June 10 and June 17.
Yogi Berra should have been in the energy business. Western energy markets were fraught with déjà vu all over again this week as maintenance issues prompted prices to move lower.
Southern California Gas Co. is wrapping up maintenance activities at the Honor Rancho storage facility, putting upward pressure on regional natural gas prices.
Southern California Gas Co.'s continuing maintenance at its Honor Rancho gas storage field served to depress Southern California natural gas prices.
Last week's across-the-board increases in Western power prices failed to last amid relaxed supply constraints that freed natural gas supplies, including those earmarked for Southern California markets.
The latest manual snowpack measurements by the California Department of Water Resources at Phillips Station found April 1 conditions "well below normal," with 49.5 inches of snow depth and a snow-water equivalent of 21 inches—83 percent of average for the location.
Cooler weather and supply constraints generally bolstered Western energy prices this week. Although natural gas price trajectories varied, power prices ratcheted higher.
Weather-inflated Western energy prices continued to moderate this week. While power prices plunged sharply in trading, without the demand support or supply constraints of the prior week, regional natural gas prices leveled off.
Frigid conditions across the continental United States sent Western energy prices on a rollercoaster ride in the abbreviated Feb. 11 to Feb. 18 trading period. Markets were closed Monday, Feb. 15, in observance of Presidents Day.
Western energy price movement was nominal, if not tame, following the flip of the calendar to 2021. Demand was sufficiently soft that additions were made to California natural gas storage during the Dec. 31 through Jan. 7 trading period.
In a reversal of last week's peak power price movements, Pacific Northwest power prices picked up value while other Western hubs lost four to five dollars.
Lacking an Arctic blast or other seasonal weather changes to propel demand, Pacific Northwest power prices sagged while other regional prices ticked up a few dollars.
In initial forecasts for the 2021 Western water year, Pacific Northwest hydro generation appears to be in good shape; however, similar California forecasts have yet to be issued.
The continental United States is well-prepared for its winter heating needs with 3,920 Bcf of natural gas in storage. This is the third-greatest amount of natural gas in storage recorded at the end of a storage season and the largest amount since 2016, when there was 3,977 Bcf in storage, ac…
Increased solar generation has precipitated an added need for natural gas-fired power between 4 p.m. and 6 p.m. to meet California demand, according to a new U.S. Energy Information Administration analysis.
