Weekly Energy Industry Summary
Commodity Fundamentals
Week of September 29, 2025
By The Numbers:
- Prompt-month NYMEX natural gas settled at $3.27/MMbtu, up $.06 on Monday, September 29.
- Prompt-month crude oil settled at $62.66/bbl., down $.79 on Monday, September 29.
Natural Gas Fundamentals - Neutral/Bearish
- Weather for the coming week is neutral. It's warmer in the northern tier with little heating demand. It's warmer in the southern tier as well providing for latent power-generation demand for air conditioning. Lower-than-normal heating demand in the north and higher cooling load in the south largely offset one another.
- Storage inventories are neutral-to-bearish of gas in the coming week. There is a clear line of sight to full inventory by the end of October.
- Production is strong, averaging above 107 Bcf per day consistently through this month.
- The supply/demand balance favors the supply side for the coming week.
- Softness in the prompt and nearby months will persist.
- The first winter forecasts are mixed; some colder, some warmer. The tropics are heating up, but the season is entering its later stage.

Crude Oil - Neutral/Bearish
- NYMEX (WTI) prompt-month-crude settled at $62.66/bbl., down $.79, on Monday, September 29.
- Oil falls as OPEC plan adds to expectations of supply surplus.
- OPEC is planning another increase of output in November.
- Iraq's Kurdistan crude oil flows to Turkey resume adding additional supply to a well supplied market.
- If a peace plan for Gaza is realized, regular shipments through the Suez Canal may resume and this could bring some additional downward pressure on crude.

Economy - Neutral
- The U.S. Government is poised to shut down at midnight.
- U.S. GDP grew at 3.8% in the second quarter, The Bureau of Economic Analysis reports.
- Imports decreased and consumer spending increased during the second quarter.
- Consumer spending increased by 2.5% instead of the previously reported 1.6%.
- Weekly claims for unemployment benefits fell 14,000 to 218,000.
- Strong demand for business equipment pursuant to AI was cited as a positive factor.
- The unemployment rate is 4.3%.

Weather - Neutral
- Warmer than normal prevails in the 6-10 day forecast through much of the country.
- Warmer in the north means lower demand for typical seasonal heating.
- Warmer in the south means latent air-conditioning load.
- The two largely offset one another relative to natural gas demand.

Weekly Natural Gas Report:
- Inventories of natural gas in underground storage for the week ending September 19 are 3,508 Bcf; an injection of 75 Bcf was reported for the week ending September 19.
- Gas inventories are 203 Bcf above the five-year average and 22 Bcf more than the same time last year.




Weekly Power Report:
Mid-Atlantic Electric Summary
- The Mid-Atlantic Region’s forward power prices were slightly higher on the week despite natural gas prices continuing to absorb the overall bearish market fundamentals, including strong production and signs of supply increasing further. The latest weather models reveal that the highest temperature anomalies remain in the north-central third of the nation, and occasionally in the East, while the West is experiencing some cooler changes. As a result, the heating season is off to a slow start, and cooling demand is extending further into the fall. Power forward prices were 1% higher over the past week and 4% higher over the past month. The month-to-date, day-ahead settlement average price in West Hub for September is $40.88/MWh, which is 14% higher than last month and 32% higher than a year ago.
- Governors Hold Technical Conference, Establish Collaborative - On 9/22, Governor Shapiro hosted the PJM’s Governors Technical Conference at the National Constitution Center in Philadelphia. The conference was a collaborative effort among the 13 PJM states’ governors to discuss potential solutions to maintain affordability and reliability in the face of rising demand for electricity and how PJM is governed and makes decisions. The conference agenda included four panels discussing resource adequacy challenges and opportunities, innovative supply and demand solutions, other RTO governance best practices, and PJM governance. The conference also included remarks from FERC Chairman David Rosner, PJM CEO Manu Asthana, and Governors Shapiro (PA-D), Youngkin (VA-R), Murphy (NJ-D), and Moore (MD-D). The event brought in approximately 450 attendees from government, industry, academia, and NGOs, plus live streaming. The first panel addressed challenges facing PJM’s capacity market and opportunities to improve that market and/or meet resource needs through alternative structures. The second panel focused on potential supply and demand solutions. Panelists discussed improvements to load forecasting, adoption of state or utility level large load tariffs, opportunities for new load to bring its own generation, the use of power purchase and other bilateral agreements, and improvements to demand response. The third panel discussed differences in PJM’s governance model compared to other RTO governance and decision-making models and the final panel focused more specifically on PJM’s governance structure. After the conference, governors from eleven of the PJM states (Kentucky, West Virginia, and Washington, DC not participating) announced the launch of the PJM’s Governors Collaborative, a new bipartisan forum that will allow governors to act collectively on issues of grid governance, energy affordability, and market reform.




Great Lakes Electric Summary
- The Great Lakes Region’s forward power prices were slightly higher on the week despite natural gas prices continuing to absorb the overall bearish market fundamentals, including strong production and signs of supply increasing further. The latest weather models reveal that the highest temperature anomalies remain in the north-central third of the nation, and occasionally in the East, while the West is experiencing some cooler changes. As a result, the heating season is off to a slow start, and cooling demand is extending further into the fall. Power forward prices were 1% higher over the past week and 5% higher over the past month. The month-to-date, day-ahead settlement price average in COMED for September is $36.61/MWh, which is -1% lower than last month, while in AdHub the price is $39.48/MWh or 9% higher than last month. In Michigan the month-to-date, day-ahead settlement price average is $39.75/MWh or -7% lower than August, while Ameren’s current price average is $38.62/MWh, or -3% lower than last month.

Northeast Energy Summary
- Exactly one month from the original work-stop order, a federal judge ruled on September 22 that Orsted can resume construction on its Revolution Wind project off the shores of Massachusetts and Rhode Island. On August 22 the US Bureau of Ocean and Energy Management (BOEM) ordered all activities to be halted as a matter of national security and to prevent “interference with reasonable uses of the exclusive economic zone, the high seas, and the territorial seas.” The 700-MW wind farm is about 80% complete with 45 out of 60 total turbines planned installed and is under contract to deliver clean power supply to both Rhode Island and the state of Connecticut. This ruling to reverse cited that project could suffer “irreparable harm” unless construction proceeded. Though the decision provides relief to its stakeholders in the short-term many expect the Presidential administration to continue its case and potentially take further actions to thwart the offshore wind farm.
- In other New England offshore wind news, BOEM filed a motion to remand the "construction and operations plan" (COP) of the SouthCoast Wind project on September 18. The SouthCoast Wind project is a 2,400 MW, 141-turbine project off the coast of Massachusetts not yet under construction but currently has all necessary permits in hand. Ocean Winds, the project's developer, originally received the COP three days before President Trump took office back in January. The filing notes that the COP approval may not have fully complied with the law regarding the use of federal waters which they feel is reason enough to remand. OW plans on vigorously defending the permits in court.
- Earlier this month, the New York Public Service Commission (PSC) declared the Northeast Supply Enhancement (NESE) pipeline project necessary for the reliability of the downstate gas system, marking a significant victory for the project's proponents. Despite this endorsement, the project still faces several hurdles, including securing state water quality permits. The Commission's Chair, Rory Christian, emphasized the importance of the pipeline for the reliability and resilience of the gas system, particularly in light of severe cold weather risks. The Commission's decision was influenced by concerns following Winter Storm Elliott in 2022, which highlighted vulnerabilities in the gas system. The pipeline, previously rejected in 2019 and 2020 due to water quality concerns, was revived with support from President Donald Trump. National Grid, which serves 1.9 million gas customers in New York City and Long Island, has been a strong advocate for the pipeline, arguing that it is essential for enhancing system reliability. National Grid is currently relying on trucked-in gas to meet peak winter demand; a strategy viewed as risky by the Department of Public Service staff and commissioners. However, the pipeline's approval remains contentious. Environmental groups have criticized the lack of public hearings and pushed for a longer public comment period. Additionally, the pipeline still requires water quality permits from New York and other states. The Department of Environmental Conservation is currently reviewing comments on the NESE project application and is expected to make a decision by 11/30. The Commission has directed National Grid to provide more information about its demand forecasts, continue evaluating supply options, and identify additional risk reduction measures. The company will also analyze the possibility of decommissioning the Greenpoint liquefied natural gas facility if the pipeline is built. Another long-term plan for National Grid's gas system is expected in 2028.




ERCOT Energy Summary




CAISO, Desert Southwest and Pacific Northwest Energy Summary
- Forecasts trended in the cooler direction over the weekend as a series of Pacific fronts will erode some of the warmth the West has experienced over the past few weeks. But trending cooler does not mean actual cool weather. The “color” of the forecast in fact, as viewed through the eyes of a weatherperson, is sea of white with barely a hint of orange or blue to indicate a deviation above or below normal. The interior west is seeing deviations towards the above side of the spectrum, but not remarkably so. We’re heading back towards low seasonal loads. Renewable generation in California will be dominated this week by midday solar output as forecasts indicate only sporadic clouds drifting over panels across the state suggesting output will average 75-90% of nameplate.
- City gate basis prices trended lower on Monday as very average weather conditions and plenty of solar generation translates to less need for thermal generation within SoCal. Gas storage is in a very comfortable position as of Monday’s reports, the needle for SoCalGas is now showing the same level in the tank as this time last year at 106 Bcf. PG&E continues to run a little ahead of its yr ago position at 171 Bcf. Market sentiment could turn quickly if cooler weather makes a surprise appearance in the Golden State. The combination of mild temperatures and solar output has made the South to North constraint in CAISO day ahead prices part of the daily conversation again. Prices at SP15 were running in the $10 – 12 MWh range below NP15 prices over the weekend. That spread blew out to an over $20 MWh discount for SP15 to NP15 during the peak period for flow on Tuesday. Weather forecasts for Wednesday and Thursday point towards an increase in solar generation which would make the latter part of the week much more susceptible to curtailments and even larger congestion pricing differentials in SP15. Day ahead index energy buyers in SP15 will enjoy this return to springtime pricing much as the battery fleet owners in southern part of the state.
- Enjoy your New (Water) Year’s Eve celebrations tonight. Water Year 2025 – 2026 begins Wednesday.
