California regulators approve increase in working natural gas storage capacity at Aliso Canyon:
On August 31, the California Public Utilities Commission (CPUC) voted to increase the working natural gas storage level to 68.6 billion cubic feet (Bcf) at Aliso Canyon, California’s largest underground natural gas storage facility located northwest of Los Angeles. The CPUC stated the increase of 27.4 Bcf from about 41.2 Bcf was necessary to moderate potential energy price increases and enhance reliability for the upcoming 2023–2024 winter. In its decision, the CPUC acknowledged that increasing the working gas storage capacity at this time is an interim solution to meet Southern California’s immediate natural gas and electricity needs; the CPUC remains committed to reducing California’s reliance on natural gas in the long term. In the absence of regulatory caps, Aliso Canyon has a total working natural gas storage capacity of 86.2 Bcf, or about 63% of the Southern California Gas Company (SoCalGas) total. Following a well leak in 2015 and the plugging of that well in 2016, several other wells at the storage field were taken out of operation and Aliso Canyon has been operating at reduced capacity. Since July 2017, when Aliso Canyon was cleared to resume partial operation, the CPUC has revised the inventory level cap at Aliso Canyon several times in response to changing market conditions. In November 2021, the CPUC capped the Aliso Canyon inventory level at about 41.2 Bcf. In April of this year, SoCalGas and the San Diego Gas & Electric Company (SDG&E) filed a petition with the CPUC proposing the Commission modify the November 2021 decision that set the current working gas inventory level at Aliso Canyon. In their petition, SoCalGas and SDG&E asserted that increasing the storage level at Aliso Canyon would decrease the likelihood of price spikes like those experienced during winter 2022–2023. Natural gas prices at SoCal Citygate traded between $20.00 per million British thermal units (MMBtu) and $50.00/MMBtu for most of December 2022, partly because of low natural gas storage levels. The U.S. West Coast experienced several weeks of below-average temperatures during the 2022–2023 winter, which resulted in increased heating demand and large withdrawals of natural gas from storage. SoCalGas’s storage levels were 14% above the five-year (2017–2021) average at the start of the heating season on November 1, 2022, and fell to 30% below the five-year (2018–2022) average on March 31, 2023. As of August 31, natural gas storage in the SoCalGas system in Southern California was about 86% full at 79.2 Bcf when accounting for the cap of 41.2 Bcf on Aliso Canyon’s inventory level. From August 14 through September 1, SoCalGas reported that the Aliso Canyon storage field was full. The CPUC decision lifts the restriction as of September 2 and allows Aliso Canyon to increase its natural gas storage level in the remaining weeks of this injection season (April–October) ahead of the coming winter heating season.

The NYMEX January 2024 contract reflects about a $1.17/MMBtu premium to the October 2023 contract. Select regional spot prices: Natural gas spot prices fell at most locations this report week (Wednesday, August 30 to Wednesday, September 6), except in the Northeast. Price changes this week ranged from a decrease of $0.77/MMBtu at PG&E Citygate to an increase of $1.12/MMBtu at Algonquin Citygate. Prices across the West decreased this report week. The price at PG&E Citygate in Northern California fell 77 cents, down from $4.51/MMBtu last Wednesday to $3.74/MMBtu yesterday, and the price at SoCal Citygate in Southern California decreased 63 cents from $3.71/MMBtu last Wednesday to $3.08/MMBtu yesterday. Natural gas consumption in the electric power sector in the Western region decreased by 20%, or 1.2 billion cubic feet per day (Bcf/d), this week, according to S&P Global Commodity Insights (SPGCI). More than half of the decline in electric power consumption (0.7 Bcf/d) occurred in California. Temperatures in the Riverside Area, east of Los Angeles, averaged 75°F this week, resulting in 73 cooling degree days (CDD), 56 fewer CDDs than last week and 26 fewer than normal. In the Desert Southwest, the price at the El Paso South Mainline/North Baja pricing point for deliveries from the Permian Basin into Arizona and western New Mexico decreased 80 cents this report week, down from $3.42 last Wednesday to $2.62/MMBtu yesterday, reflecting cooler temperatures and decreased air-conditioning demand in the region. In the Phoenix Area, temperatures averaged 91°F this report week, 11°F below last week’s average of 102°F. The lower average temperatures resulted in 185 CDDs this week, 74 fewer CDDs than last week and 9 fewer than normal. Natural gas consumption in the electric power sector in the Desert Southwest decreased 15% (0.4 Bcf/d) week over week, according to data from SPGCI. In the Northeast, at Algonquin Citygate, which serves Boston-area consumers, the price went up $1.12 from $1.43/MMBtu last Wednesday to $2.55/MMBtu yesterday. In the Boston Area, temperatures averaged 72°F this week, resulting in 52 CDDs, 16 more than last week and 15 CDDs more than normal. At the Transcontinental Pipeline Zone 6 trading point for New York City, the price increased 78 cents from $1.35/MMBtu last Wednesday to $2.13/MMBtu yesterday. Temperatures in the New York-Central Park Area averaged 77°F, which resulted in 84 CDDs, 16 CDDs more than last week. Above-average temperatures led to increased demand for air conditioning, and as a result natural gas consumption in the electric power sector in the Northeast rose 5.0% (0.5 Bcf/d) this week, according to data from SPGCI.

Supply and Demand
Supply: According to data from SPGCI, the average total supply of natural gas fell by 0.5% (0.6 Bcf/d) compared with the previous report week. Dry natural gas production decreased by 0.4% (0.4 Bcf/d) to average 102.2 Bcf/d, and average net imports from Canada decreased by 3.5% (0.2 Bcf/d) from last week. Demand: Total U.S. consumption of natural gas fell by 3.9% (2.9 Bcf/d) compared with the previous report week, according to data from SPGCI. Most of the decrease was due to a 7.1% (3.2 Bcf/d) week-over-week reduction in natural gas use for power generation. Industrial sector consumption increased by 0.3% (0.1 Bcf/d) and residential and commercial sector consumption increased by 2.5% (0.2 Bcf/d). Natural gas exports to Mexico were essentially unchanged this week. Natural gas deliveries to U.S. LNG export facilities (LNG pipeline receipts) averaged 13.0 Bcf/d, or 0.9 Bcf/d higher than last week.
Liquefied Natural Gas (LNG)
Pipeline receipts: Average natural gas deliveries to U.S. LNG export terminals increased by 7.1% (0.9 Bcf/d) week over week, averaging 13.0 Bcf/d, the highest weekly average since May, according to data from SPGCI. Natural gas deliveries to terminals in South Louisiana increased by 8.0% (0.6 Bcf/d) to 7.8 Bcf/d, while deliveries to terminals in South Texas increased by 6.4% (0.2 Bcf/d) to 4.1 Bcf/d. Natural gas deliveries to terminals outside the Gulf Coast were essentially unchanged at 1.0 Bcf/d. Vessels departing U.S. ports: Twenty-six LNG vessels (nine from Sabine Pass; four each from Corpus Christi and Freeport; three from Calcasieu Pass; and two each from Cameron, Cove Point, and Elba Island) with a combined LNG-carrying capacity of 96 Bcf departed the United States between August 31 and September 6, according to shipping data provided by Bloomberg Finance, L.P.
Storage
Net injections into storage totaled 33 Bcf for the week ending September 1, compared with the five-year (2018–2022) average net injections of 60 Bcf and last year’s net injections of 55 Bcf during the same week. Working natural gas stocks totaled 3,148 Bcf, which is 222 Bcf (8%) more than the five-year average and 462 Bcf (17%) more than last year at this time. According to The Desk survey of natural gas analysts, estimates of the weekly net change to working natural gas stocks ranged from net injections of 31 Bcf to 58 Bcf, with a median estimate of 41 Bcf. The average rate of injections into storage is 5% lower than the five-year average so far in the refill season (April through October). If the rate of injections into storage matched the five-year average of 11.1 Bcf/d for the remainder of the refill season, the total inventory would be 3,817 Bcf on October 31, which is 222 Bcf higher than the five-year average of 3,595 Bcf for that time of year.
