New natural gas-fired capacity additions expected to total 8.4 gigawatts in 2023
So far in 2023, 10 natural gas-fired power plants have come online in the United States with a total of 6.6 gigawatts (GW) of electric generating capacity, according to our Monthly Electric Generator Inventory. By the end of 2023, we expect another six natural gas-fired power plants with another 1.8 GW of capacity to come online, bringing total 2023 capacity additions to 8.4 GW. The additions include both combined-cycle gas turbine (CCGT) plants and simple-cycle gas turbine (SCGT) plants concentrated near the Gulf Coast and Appalachia natural gas producing regions, and in Florida. In 2022, a total of 11 natural gas-fired power plants came online, adding 5.5 GW of capacity. Total natural gas-fired capacity additions increased in both 2022 and 2023 after consecutive declines in the prior three years. In the next two years (2024 and 2025), we expect 20 new natural gas-fired power plants to come online with a total capacity of 7.7 GW. CCGT plants commonly serve both base and peak electricity load because they are highly efficient and designed to run for extended periods of time. During 2022 and 2023, a total of 13 new CCGT plants with a combined capacity of 11.9 GW will have entered service. The average output for each of the 13 CCGT plants is 0.9 GW of electric generating capacity. Approximately 5.8 GW of the total capacity is located in Florida and Michigan. These two states already produce electricty primarily from natural gas-fired power plants. We expect 4.9 GW of additional CCGT additions in 2024 and 2025, only 0.1 GW of which is planned for 2024. During 2022 and 2023, 14 SCGT plants with total capacity of 1.9 GW will have begun operations. The average output for each of the 14 SCGT plants is 140 megawatts of electric generating capacity. Although the average capacity of SCGT plants is much lower than CCGT plants, SCGT plants are able to quickly ramp up operations in response to sudden changes in demand or when output from intermittent renewable energy sources is unavailable. Over half of the new SCGT capacity coming online in 2022 and 2023 is located in Texas, which has periods of high daily peak electricity demand throughout the summer and has had significant growth in renewable energy during the last few years. Additional new SCGT units with a total capacity of 2.8 GW, mostly located in Texas near high population areas, are expected to enter service in 2024 and 2025.

The price at SoCal Citygate in Southern California increased 12.5 cents from $3.58/MMBtu last Wednesday to $3.71/MMBtu yesterday, and the price at PG&E Citygate in Northern California increased 37 cents from $4.14/MMBtu last Wednesday to $4.51/MMBtu yesterday. Ongoing maintenance in New Mexico by El Paso Natural Gas has led to capacity constraints for natural gas flowing westbound into Southern California. Prices in the region reached an intraweek daily high of $4.23/MMBtu in the Desert Southwest (the El Paso South Mainline/North Baja pricing point) and $10.02/MMBtu at SoCal Citygate on August 28, as temperature-related demand in the region rose amid maintenance constraints. Temperatures in the Phoenix Area in Arizona reached a monthly high of 117°F, over 11°F above normal, and in the Riverside Area, east of Los Angeles, temperatures averaged 83°F this week, resulting in 129 cooling degree days (CDD), 33 more CDDs than last week and 26 more CDDs than normal. In the Southeast, prices fell this report week despite increased consumption of natural gas. The price at FGT Citygate fell 93 cents from $4.49/MMBtu last Wednesday to $3.57/MMBtu yesterday. The weekly decrease in price occurred as Hurricane Idalia reached the coast of Florida on August 30 and caused widespread power outages in Florida and Georgia, decreasing demand for electric power generation. The FGT Citygate price reflects deliveries into Florida via the Florida Gas Transmission system. Although prices decreased at FGT Citygate, consumption of natural gas throughout the broader Atlantic Coast region rose week over week, driven by higher-than-normal temperatures that supported cooling demand. On the Atlantic Coast, natural gas consumption in the electric power sector rose 3% (0.2 Bcf/d) week over week, and total natural gas consumption rose 2% (0.2 Bcf/d), according to data from S&P Global Commodity Insights (SPGCI). International futures prices: International natural gas futures prices decreased this report week. According to Bloomberg Finance, L.P., weekly average front-month futures prices for liquefied natural gas (LNG) cargoes in East Asia decreased 76 cents to a weekly average of $13.33/MMBtu. Natural gas futures for delivery at the Title Transfer Facility (TTF) in the Netherlands decreased $1.13 to a weekly average of $11.22/MMBtu. In the same week last year (week ending August 31, 2022), the prices were $64.02/MMBtu in East Asia and $83.62/MMBtu at TTF, the highest weekly average TTF price on record. International natural gas prices have been volatile throughout August due to uncertainty about Australian LNG supplies amid the potential for labor stoppages.

Storage
Net injections into storage totaled 32 Bcf for the week ending August 25, compared with the five-year (2018–2022) average net injections of 51 Bcf and last year’s net injections of 61 Bcf during the same week. Working natural gas stocks totaled 3,115 Bcf, which is 249 Bcf (9%) more than the five-year average and 484 Bcf (18%) more than last year at this time. Net injections have trailed the five-year average for eight consecutive weeks. 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 21 Bcf to 36 Bcf, with a median estimate of 31 Bcf. The average rate of injections into storage is 4% 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 10.9 Bcf/d for the remainder of the refill season, the total inventory would be 3,844 Bcf on October 31, which is 249 Bcf higher than the five-year average of 3,595 Bcf for that time of year.
