In the News:
Natural gas-fired electricity generation was higher in first-half 2023 than in first-half 2022
Natural gas-fired electricity generation across the Lower 48 states increased by 9.7%, or 66.2 terawatthours (TWh), in the first half of 2023 (1H2023) compared with the first half of 2022 (1H2022), making it the single largest growing source of electricity generation, according to data from our Hourly Electric Grid Monitor. The increase in natural gas-fired generation was driven by lower natural gas prices and lower generation from other sources, in particular coal, and occurred despite a 2.9% (57.5 TWh) decline in total electricity generation, largely attributable to mild weather.
Natural gas-fired electricity generation peaks in the summer when electricity demand for air conditioning is highest due to seasonally high average temperatures. Another lower peak occurs during the winter, when use of heat pumps, electric radiators, space heaters, and other electric heating equipment to heat buildings increases in some parts of the United States. Over the first six months of this year, the cumulative number of population-weighted heating degree days across the Lower 48 states was 10.2% lower than the 10-year (2013–2022) average and 11.6% lower than 1H2022, while the cumulative number of cooling degree days was 23.1% lower than the 10-year average and 33.7% lower than 1H2022. This mild weather contributed to a decline in overall electricity generation compared with 1H2022.
Coal-fired electricity generation decreased the most out of all the fuel sources in 1H2023, declining 25.8% (107.2 TWh) compared with 1H2022. In the electric power sector, combined-cycle natural gas-fired generation units typically compete with coal-fired generation units to provide the lowest-cost wholesale electricity price for power suppliers. Coal-fired generation this year has been less economical compared with natural gas-fired generation, leading to price-driven coal-to-natural gas fuel switching.
The U.S. electric power sector natural gas cost averaged $3.74 per million British thermal units (MMBtu) in 1H2023, 43.3% ($2.85/MMBtu) lower than in 1H2022, while the electric power sector coal cost averaged $2.52/MMBtu in 1H2023, according to our Short-Term Energy Outlook. The electric power sector natural gas cost has been declining this year, averaging $2.39/MMBtu in June, while the electric power sector coal cost averaged $2.45/MMBtu in June.
Capacity additions have also contributed to the growth in natural gas-fired generation. Between 1H2022 and 1H2023, average U.S. natural gas-fired generation capacity increased by 1.5%, while coal-fired generation capacity decreased by 6.4%, continuing a long-term trend of coal capacity retirements. According to our Electric Power Monthly, over the 12 months ending in April 2023, 9.1 gigawatts (GW) of net natural gas-fired electric power generation capacity additions entered service, of which 93.4% (8.5 GW) were from combined-cycle natural gas turbine plants, which are among the most efficient natural gas plants and help improve the economics of natural gas-fired generation compared with other sources.
In addition to coal, smaller declines in electricity generation from wind (6.3%, or 15.2 TWh), hydropower (6.2%, or 9.0 TWh), nuclear (0.9%, or 3.5 TWh), and petroleum (20.5%, or 1.1 TWh) also contributed to increased natural gas-fired generation in 1H2023 compared with 1H2022, while electricity generation from solar power increased (8.3%, or 5.4 TWh).

Price changes this week ranged from a decrease of $0.20/MMBtu at Tennessee Zone 4 Marcellus to an increase of $2.24/MMBtu at SoCal Citygate.
- Prices decreased in all Northeast markets this report week, despite warmer-than-average temperatures in New England and in New York City. At the Algonquin Citygate, which serves Boston-area consumers, the price went down 13 cents from $1.87/MMBtu last Wednesday to $1.74/MMBtu yesterday. At the Transcontinental Pipeline Zone 6 trading point for New York City, the price decreased 14 cents from $1.79/MMBtu last Wednesday to $1.65/MMBtu yesterday. In the Boston-Area, temperatures averaged 78°F this week, 4°F above normal, resulting in 17 more cooling degree days (CDDs) than last week and 29 more than normal. Temperatures in the New York-Central Park Area averaged 79°F this week, 1°F above normal, which resulted in 11 fewer CDDs than last week but 8 more than normal. Natural gas consumption in the Northeast power sector increased 1%, or 0.1 billion cubic feet per day (Bcf/d) week over week, according to data from S&P Global Commodity Insights.
- In western markets, from the Opal Hub in southwest Wyoming to Sumas on the Canada-Washington border, prices increased from last Wednesday to yesterday. The price at the Opal Hub rose 97 cents from $2.80/MMBtu last Wednesday to $3.77/MMBtu yesterday, and the price at Sumas rose 95 cents from $2.86/MMBtu last Wednesday to $3.81/MMBtu yesterday. Capacity reductions on the two major pipelines delivering natural gas into the Pacific Northwest continued this week. Gas Transmission Northwest extended its force majeure through July 24, reducing available capacity by approximately 0.4 Bcf/d at the Kingsgate delivery point in Boundary, Idaho. Available capacity on the Westcoast Energy Inc. pipeline, which delivers natural gas from British Columbia into Washington, continues to be down by approximately 0.5 Bcf/d.

Natural gas deliveries to terminals in South Texas increased by 4.5% (0.2 Bcf/d) to 4.1 Bcf/d, while deliveries to terminals in South Louisiana decreased by 1.0% (0.1 Bcf/d) to 7.3 Bcf/d. Natural gas deliveries to terminals outside the Gulf Coast were essentially unchanged at 1.1 Bcf/d.
- Vessels departing U.S. ports: Twenty-two LNG vessels (seven from Sabine Pass, five from Corpus Christi, three each from Cameron and Freeport, and two each from Calcasieu Pass and Cove Point) with a combined LNG-carrying capacity of 82 Bcf departed the United States between July 13 and July 19, according to shipping data provided by Bloomberg Finance, L.P.
- Vessels arriving at U.S. ports: One LNG vessel with a carrying capacity of 3 Bcf docked for off-loading at the Everett LNG terminal in Boston Harbor in Massachusetts between July 13 and July 19, according to shipping data provided by Bloomberg Finance, L.P.
Rig Count
- According to Baker Hughes, for the week ending Tuesday, July 11, the natural gas rig count decreased by 2 rigs from a week ago to 133 rigs. The Eagle Ford, Haynesville, and Permian each dropped one rig, and one rig was added in an unidentified producing basin. The number of oil-directed rigs decreased by 3 rigs from a week ago to 537 rigs. The Permian dropped four rigs, the Cana Woodford and Mississippian each dropped one rig, one rig was added in the Williston, and two rigs were added in unidentified producing basins. The total rig count, which includes 5 miscellaneous rigs, stands at 675, 81 fewer rigs than last year at this time.
Storage
- The net injections into storage totaled 41 Bcf for the week ending July 14, compared with the five-year (2018–2022) average net injections of 45 Bcf and last year's net injections of 35 Bcf during the same week. Working natural gas stocks totaled 2,971 Bcf, which is 360 Bcf (14%) more than the five-year average and 575 Bcf (24%) 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 37 Bcf to 57 Bcf, with a median estimate of 44 Bcf.
- The average rate of injections into storage is 6% higher 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 9.0 Bcf/d for the remainder of the refill season, the total inventory would be 3,955 Bcf on October 31, which is 360 Bcf higher than the five-year average of 3,595 Bcf for that time of year.
