US Power Update: Prices Mostly Higher Thursday Afternoon, 7 Regions Top $100/MWh

By

US wholesale electricity markets were mostly higher Thursday afternoon, with seven regions seeing intraday price spikes above $100 per megawatt-hour, according to GridStatus.io.

Electric Reliability Council of Texas' real-time locational marginal price stood at $55.83/MWh at 4 p.m. ET. Net load was 51.39 gigawatts, while natural gas made up the largest portion of the generation mix at 43.3%. Prices reached an intraday high of $100.04/MWh at 4:25 p.m. ET.

California Independent System Operator's real-time LMP was $32.38/MWh at 4 p.m. ET. Net load totaled 1.76 GW, with solar providing the largest share of generation at 63.9%.

Southwest Power Pool's real-time LMP reached $77.24/MWh at 4 p.m. ET. Net load was 41.14 GW, and natural gas made up the largest share of the generation mix at 41%. Prices hit an intraday high of $263.98/MWh at 3:15 p.m. ET.

PJM Interconnection's real-time LMP was $279.96/MWh at 4 p.m. ET. Net load stood at 114.25 GW, with gas accounting for the biggest share of the generation mix at 46.6%. Prices climbed to an intraday high of $558.07/MWh at 5:50 a.m. ET.

Midcontinent Independent System Operator's real-time LMP came to $148.92/MWh at 4 p.m. ET. Net load reached 86.39 GW, while natural gas supplied the largest share of generation at 35.3%. Prices rose to an intraday high of $192.17/MWh at 1:05 a.m. ET.

New York Independent System Operator's real-time LMP stood at $103.75/MWh at 4 p.m. ET. Net load totaled 21.74 GW, with dual-fuel sources representing the largest share of the generation mix at 34.6%. Prices reached an intraday high of $142.52/MWh at 2:50 p.m. ET.

ISO New England's real-time LMP was $86.16/MWh at 4 p.m. ET. Net load came in at 16.03 GW, while natural gas accounted for the largest share of the generation mix at 60.3%. Prices climbed to an intraday high of $124.58/MWh at 1 p.m. ET.

Independent Electricity System Operator's real-time LMP reached $103.33/MWh at 4 p.m. ET. Net load was 18.35 GW at 3:55 p.m. ET, with nuclear providing the largest share of generation at 42.8%. Prices hit an intraday high of $131.01/MWh at 1:50 p.m. ET.

The National Weather Service's Climate Prediction Center forecasts above-normal temperatures across most of the US from Sept. 25-Oct. 1, with near-normal readings in parts of the West and Northeast.

Unseasonable heat is straining power grids as operators take generating units offline for maintenance, with some areas facing temperatures more than 20F above normal, according to a Bloomberg report Thursday.

MISO reported about 51 GW of generation outages Thursday, while demand could reach 105.2 GW, adding pressure to available power supplies, according to the report.

PJM activated Demand Response resources across its footprint on Sept. 17 to boost reserves for the evening peak, according to a PJM statement on Thursday. The operator said the move was prompted by unusually warm September weather along with planned generation or transmission outages.

A Max Generation/Load Management Alert was also in effect, leading to deferral of equipment maintenance and expected curtailment of exports to neighboring systems, with load forecast to peak at about 132,000 megawatts, PJM said.

Farm Bill Clears Senate Committee, Setting Up Floor Vote on Year-Round E15

The US Senate Agriculture Committee voted Wednesday to move the Agricultural Act of 2026, also known as the Farm Bill, to the full Senate floor, including a provision allowing year-round sales of E15 gasoline.The bill now moves to the Senate floor for the full body to consider sometime before an October adjournment.The House passed year-round E15 legislation in May by a bipartisan 218-203 vote.The Renewable Fuels Association welcomed the move. "Today's passage of the farm bill by the Senate Agriculture Committee represents an important step toward finally securing nationwide, year-round E15," said RFA President and CEO Geoff Cooper."As expressed throughout the farm bill process, there is broad bipartisan support for making lower-cost E15 available to consumers all year long-especially at a time when pump prices are on the rise and fuel supplies are tightening," Cooper noted.A recent US Department of Energy report found that E15 has been selling for 47 cents per gallon less than standard E10 gasoline on average, for an 11.5% discount.Year-round E15 also has strong support from President Trump, according to the RFA.In a statement, the RFA said that in a supplemental funding request to Congress in June, the Trump administration requested, "... a fix that codifies the permanent, year-round sale of E15, an urgent and needed policy change that would expand consumer choice, support domestic fuel production, and provide additional flexibility in fuel markets."

US Natural Gas Update: Futures Slip Ahead of Smaller-Than-Normal Storage Build

US natural gas futures softened further in after-hours trading Wednesday as the market looked ahead to government data expected to show a smaller-than-normal increase in storage inventories.The front-month Henry Hub contract and the continuous contract each fell 0.92% to $2.892 per million British thermal units.Analysts polled by The Wall Street Journal expect the US Energy Information Administration to report a 48 billion cubic feet increase in natural gas inventories for the week ended Sept. 11, well below the five-year average build of 74 Bcf for the same week.As of Sept. 4, US natural gas inventories were 2.7% below year-earlier levels but 4.8% above the five-year seasonal average, indicating that overall supplies remained adequate.On the fundamentals side, warmer-than-normal temperatures are helping keep power burn elevated, while record domestic production continues, Pinebrook Energy Advisors said.Barchart, citing data from The Commodity Weather Group, said Wednesday that above-average temperatures are expected across the South and Southeast through Sept. 25. The warm late-summer temperatures are expected to support demand for natural gas from power generators as air-conditioning use continues into early autumn.Celsius Energy data showed a 0.9 Bcf increase in powerburn on Tuesday, putting Sept. 15 powerburn at 42.9 Bcf. For the week ended Tuesday, powerburn averaged 43.7 Bcf/d, up 4.8 Bcf/d from the same week a year earlier.Total US natural gas demand on Wednesday was pegged at 76.3 Bcf/d, up 2.4% year over year, Barchart said, citing BNEF data.On the supply side, US Lower 48 dry gas production remained strong at 112.3 Bcf/d on Wednesday, up 4.0% from a year earlier, Barchart said.Estimated net gas flows to US liquefied natural gas export terminals were 18.5 Bcf/d on Wednesday, down 4.7% from the previous week."LNG exports remain near 19 Bcf per day and are poised to show another leg of growth before the end of the year," Pinebrook Energy said.
