Average wholesale day-ahead electricity prices at most major trading hubs in the Lower 48 states were higher in 2025 than in 2024, driven largely by higher natural gas prices to electric generators. The largest increase in price was
$29 per megawatthour (MWh) in New England’s Independent System Operator (ISO-NE), and the largest decrease was
$14/MWh in the upper Northwest’s Mid-Columbia.
The wholesale price of electricity on the electric power grid reflects the day-ahead and real-time cost for supplying electricity, which can be driven by fluctuations in demand and fuel costs. Most retail customers pay prices based on the seasonal average cost of providing electricity and do not experience these daily price fluctuations. Price changes for natural gas have an outsized influence on wholesale electricity prices because natural gas prices set the marginal price of electricity during most hours in most regional markets.
