Natural gas market volatility tapered off a bit in May compared to the heightened price swings we observed in April. However, this didn’t translate to price stagnation. The June 2025 NYMEX contract experienced a mid-month high of $3.84 and a low of $3.10, ultimately settling at $3.20, just $3.4 cents above the May 2025 contract settlement. Meanwhile, next-day cash prices at the Henry Hub averaged $3.12 during the month.
Analysts are anticipating continued softness in Henry Hub cash prices into June until the onset of sustained summer heat, when natural gas-fired power plants will begin to play a significant role on the demand side of the equation.

Liquefied natural gas (LNG) infrastructure expansion remains a key driver of market dynamics. The Plaquemines LNG facility, which began receiving natural gas in late December 2024, is now processing approximately 2.5 Bcf per day (Bcf/d). The Corpus Christi Stage 3 project is on track to begin operations later this summer and is expected to add roughly 0.75 Bcf/d of new demand by the end of the year. Lastly, while the Golden Pass LNG project has experienced delays, it’s projected to begin commissioning activities by late 2025.
Market fundamentals continue to support a bullish outlook for winter 2025 and into 2026, driven by anticipated growth in LNG export capacity. This price strength has also extended to longer-dated contracts, with calendar year 2028 pricing rising approximately $0.30 over the past two months from around $3.50 to $3.80.

As we approach the peak of summer, forward power prices have shown a surprising trend: a steady decline. Over the past month, summer futures have dropped by approximately 14% from their May peak, reflecting a market shift that contrasts sharply with recent reliability warnings from PJM and the U.S. Department of Energy (DOE).
This phenomenon was also seen in the spot market through May, as spot prices experienced temporary spikes due to planned generator outages for seasonal maintenance. However, prices quickly reversed course, even during some of the early warm days of the season. This decline suggests that market participants are pricing in adequate near-term supply or lower-than-expected weather-driven demand. This stance may underestimate the potential risk of grid stress that both PJM and DOE have recently highlighted.
Despite this recent market bearishness, PJM Interconnection has emphasized some growing concerns in its summer readiness communications, particularly around the integration and performance of Inverter-Based Resources (IBRs), like solar and wind:
As the power generation landscape evolves, the performance of IBRs becomes much more critical to the stability of the power grid. PJM has instructed solar and wind operators to ensure their inverters are correctly configured and well-maintained as the summer demand season approaches its peak.
In parallel, on May 30, 2025, the DOE issued an emergency order directing that Units 3 and 4 of the Eddystone Generating Station in Pennsylvania be made operationally available. The DOE found that the dispatch and availability of these fossil-fuel units are “necessary to meet an emergency and serving the public interest.”

May 2025 finished 1 to 3 degrees cooler than the 30-year normal in parts of the central and eastern U.S., while the Northwest and Gulf Coast regions averaged a few degrees above average. The month ranked as the 18th warmest on record nationwide since 1950, measured by cooling degrees days. May was much cooler in the eastern U.S. compared to last year, when the region broadly averaged 4 to 5 degrees above the 30-year normal.
Forecasts for June 2025 have generally called for the strongest heat in the western U.S., and the latest medium-range weather model forecasts are in line with those predictions. Temperatures in the eastern two-thirds are on track to average near the 30-year normal, while the western-third could finish as much as 3 to 6 degrees above normal.

Natural gas markets have been less volatile than in recent months — but certainly not quiet, with prices fluctuating modestly and injections into storage hitting record highs. Strong storage injections this spring — totaling 900 Bcf so far — are offsetting earlier deficits, helping the supply picture as we head into the high-demand summer cooling season.
At the same time, growing LNG export infrastructure is reshaping long-term market dynamics, with increased demand anticipated from facilities like Plaquemines and Corpus Christi. This has the potential to signal a firmer price environment in the years ahead as LNG export demand tightens supply.
On the power side, forward and spot electricity prices have unexpectedly declined, despite reliability concerns raised by grid operators like PJM and the DOE. While markets appear to be pricing in moderate summer weather and sufficient supply, authorities are warning of tighter conditions, especially due to lower available generation and the increasing dependence on solar and wind. Emergency actions — such as the DOE’s order to bring backup fossil-fuel generators online — highlight the risk of grid stress. For consumers, this creates a paradox: Lower near-term electricity costs could be offset by vulnerability to sudden price spikes or reliability issues if heat waves or system outages arise. Overall, end users should be prepared for a summer of price variability and potential grid strain, even if current forecasts look mild.
