The shut-in of the Aliso Canyon natural gas storage facility continued supporting Western energy prices. Both natural gas and power prices were generally higher at the end of Sept. 30 to Oct. 7 trading.

As conditions across the Western U.S. began moderating, 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 surge of heat across California and Nevada starting July 9 is expected to increase energy demand as temperatures likely reach record highs through July 11.

Record and above-normal heat sent Western energy prices higher, with Pacific Northwest daytime power price highs surpassing the $100 mark June 2.

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.

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.

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.

Despite roughly similar week-over-week regional power demand, Western energy prices moved lower in Dec. 3 to Dec. 10 trading.

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.
