New York Capacity Market Signals Higher Electricity Rates Ahead
Extreme seasonal weather in New York City may not be behind us. The past two winters have been marked by unusually cold conditions, while the last two summers have brought both persistent heat and sharp, record-setting spikes. Forecasts again point to above average temperatures across much of the country this summer, with the Northeast expected to see some of the strongest heat. While these projections remain uncertain, they are an important consideration, as higher summer temperatures can increase demand and drive up electricity costs.
Perhaps more importantly, other structural factors are also shaping electricity prices in New York going forward. Electric grid capacity refers to the need to have enough generation resources available to meet projected peak demand, plus a reliability margin. Think of it as a safeguard against blackouts during periods of system stress. Like other markets, it comes down to supply and demand.
Rising electricity demand is being driven in part by increased electrification, as systems that once relied on fossil fuels shift to electric alternatives. Looking ahead, emerging sources of load such as data centers and semiconductor manufacturing are expected to add even more pressure to the grid. Seasonal demand is also evolving. Summer peaks have grown over time as cooling needs increase, and the adoption of electric heat pumps, while efficient, is contributing to higher electricity usage during both hot and cold periods.
The challenge is that as demand continues to rise, new sources of power are not coming online quickly enough. While the Champlain Hudson Power Express (CHPE), which is expected to materially increase capacity in New York City, is scheduled to enter service this spring, its timing remains uncertain. At the same time, New York has retired older nuclear facilities and higher-emitting fossil fuel plants as part of a broader effort to decarbonize the grid.
As a result, the New York Independent System Operator (NYISO) expects capacity margins this summer to be the tightest in over a decade and less than half of last year’s level.
Capacity in New York is procured through a combination of seasonal and monthly auctions. The primary seasonal auctions cover six month periods, with the most recent summer strip clearing in April for the May through October period. Monthly spot auctions then allow the market to adjust for changes in load forecasts and system conditions. This year, both the April summer strip and the May spot auction cleared at some of the highest levels in recent years.
These increases will be reflected in future electricity bills and may persist for some time. Customers with ESCO contracts that fix the capacity component are protected through the term of the agreement but should expect higher costs upon renewal. For those supplied by Con Edison, the default utility in New York City, these increases will flow through directly and are likely to be more pronounced than under a fixed ESCO contract. Con Edison’s capacity rates on average are expected to rise this summer by roughly 50 percent compared to last year. For the largest customers exceeding certain demand thresholds, increases will be as high as 126 percent in May! However, capacity charges typically account for one-third to one-half of Con Ed’s all-in supply rate in the summer months, so the overall impact on supply rates would be proportional.
In an increasingly complex and dynamic market, the role of a full-service energy advisor like Aurora is more important than ever. We help clients navigate rising costs and manage risk with a proactive, data-driven approach. For customers currently supplied by Con Edison, where these increases will be felt most directly, a clear and proactive strategy will be critical.
Market Analysis
Natural Gas
Supported by relatively strong supply fundamentals, the NYMEX May contract settled at $2.559 per MMBtu, its lowest level since November 2024. Seasonal demand remained weak during the shoulder months, while production increased, pushing working gas in storage to 5.7% above last year’s levels and 7.7% above the five-year average. The domestic natural gas market has remained largely insulated from geopolitical tensions in Iran.
Electricity
Milder weather in April helped ease previously elevated prices in NYISO Zone J. Despite this, average daily prices remained around 4.5 cents per kWh, still the third highest level over the past ten years. As discussed above, electricity costs remain elevated and may persist at higher levels for some time.
Crude Oil
Crude oil markets remain highly volatile as developments in the Middle East continue to drive uncertainty. Prices reached $115 per barrel in early April before easing to around $105 by month-end, with a pullback into the $90s in early May. Recent progress in U.S.–Iran negotiations has raised hopes for a potential de-escalation, which could help normalize markets. Still, with the situation unresolved, volatility is expected to remain elevated.
