National Grid (Niagara Mohawk) electric rates in upstate New York
National Grid's 1,449,428 default-service customers in New York paid an average of 19.89¢ per kWh in 2025, for an average bill of $129.73 a month on 652 kWh.1 Over the last 12 months (Sep 2025–Aug 2026) the average was 23.24¢, and 22.61¢ in August 2026.2 Another 87,141 homes on its wires (5.7%) buy their supply elsewhere and pay National Grid delivery charges averaging 10.37¢ per kWh, plus their supplier's price.
EIA-861 2025 final (released October 7, 2026) and EIA's monthly utility survey through August 2026 (preliminary); next monthly update expected November 24, 2026. Averages are revenue divided by kWh, all charges included: not the rate printed in a tariff.
37 of 62 New York counties served (EIA-861 2025)
National Grid still has the lowest residential average of New York's large utilities, but the gap is closing: its full-service customers paid 19.89¢ per kWh1 in 2025 and 23.24¢ per kWh2 over the 12 months to August 2026. Its bills peak in winter, not summer, and its customers spent more minutes without power than the New York average.
Three ways to answer "National Grid rates per kWh"
National Grid's New York utility is legally Niagara Mohawk Power Corporation, which is why searches for "Niagara Mohawk" and "National Grid" lead to the same company. EIA's data give three different averages for its residential customers, and each answers a different question:
- 19.89¢ per kWh1 for the calendar year 2025 (EIA-861, final annual data), the basis of the rankings below;
- 23.24¢ per kWh for the last 12 months, September 2025 to August 2026 (EIA-861M monthly sample; the 2026 months are preliminary);
- 22.61¢ per kWh2 for August 20263 alone, a single preliminary month.
All three are average revenue per kWh: what full-service customers paid in total, divided by the kWh they used. They include the customer charge, delivery charges, the supply charge and adjustments, so none of them is a tariff rate and none matches the per-kWh line on a particular bill. They cover only homes that buy their electricity from National Grid; the 87,1411 homes that bought supply from another company in 2025 are counted separately (see below).

Lowest among New York's large utilities, by a shrinking margin
In 2025, National Grid's average was 24.6% below the New York average and the 4th lowest of the 10 New York utilities with 10,000 or more full-service residential customers; the three below it are smaller systems, the lowest being the Village of Fairport (7.80¢ per kWh). Among the seven utilities with pages here, it was the lowest. RG&E averaged 22.01¢ per kWh and NYSEG 22.59¢ per kWh, while downstate Con Edison averaged 36.74¢ per kWh1.

| Utility | average residential price (bundled customers) |
|---|---|
| National Grid (NY) | 19.89¢ |
| RG&E (NY) | 22.01¢ |
| NYSEG (NY) | 22.59¢ |
| PSEG Long Island (LIPA) (NY) | 26.17¢ |
| Orange & Rockland (NY) | 26.21¢ |
| Central Hudson (NY) | 27.67¢ |
| Con Edison (NY) | 36.74¢ |
The lead narrowed over the last 12 months (September 2025 to August 2026). National Grid's average reached 23.24¢ per kWh, against 23.88¢ per kWh at RG&E and 24.86¢ per kWh at NYSEG. In August 20263, against the same month a year earlier, the residential average changed by +22.2% at National Grid, −7.2% at NYSEG and +10.6%2 at RG&E. One preliminary month swings with supply costs and billing cycles, so the 12-month figure is the steadier comparison.
Nationally the picture is different. National Grid's 2025 average ranked 36th highest of 177 large utilities and was 11.9% above the national average for investor-owned utilities. The median of those 177 utilities was 15.07¢ per kWh1.
How much the price rose, 2024 to 2025
The annual residential average went from 17.22¢ per kWh in 2024 to 19.89¢ per kWh in 2025, a rise of 15.5%. Use per home also edged up, from 637 kWh to 652 kWh a month, so the average bill rose more than the price: from $109.744 to $129.73 (+18.2%1). The New York average residential price rose 8.0%5 over the same two years.
National Grid's increase was not the largest in the state: NYSEG's average rose 23.3% and RG&E's 17.3%, while Con Edison's rose 3.0%1. Rates for Niagara Mohawk's delivery service are set by the New York State Public Service Commission in rate cases, which are filed and decided in public proceedings on the Department of Public Service site. The guide to rate increases explains how those decisions reach a bill.
Bills peak in January, not July
Across New York, use per home in the last 12 months peaked in July 20263, as it did at Con Edison, NYSEG and RG&E. National Grid's customers used the most electricity in January 2026: 827 kWh per home, against 482 kWh in May 2026. The average bill followed, from $101.32 in the low month to $223.41 in the peak month. Central Hudson's use also peaked in January 20262.

Over the full 12 months (September 2025 to August 2026) National Grid homes averaged 645 kWh and $149.92 a month. That use is above the New York average of 586 kWh3 for the same period and well above the 386 kWh2 of Con Edison's customers. A household budgeting for the year should plan for the winter months rather than the annual average.
Buying supply from another company: the delivery-only figures
New York lets homes buy electricity supply from a competitive supplier while National Grid keeps delivering it. In 2025, 5.7% of National Grid's residential delivery customers did so, against 14.4% at RG&E and 10.1% at Con Edison. For those homes EIA reports only what National Grid billed for delivery: 10.37¢ per kWh on average, or $78.63 a month for 758 kWh1. Their supplier's charges come on top and are not in EIA's utility data.
That delivery-only average is not comparable with the full-service 19.89¢ per kWh: one covers delivery alone, the other delivery and supply for a different group of customers. Compared like for like, National Grid's delivery-only average was the lowest of the large New York utilities in 2025, against 13.11¢ per kWh at NYSEG and 24.29¢ per kWh at Con Edison. In 2024 it was 9.94¢ per kWh4, a change of +4.3%1, much smaller than the change in the full-service average.
Source: EIA-861 annual electric power industry report, 2025 final. Delivery charges only: what the utility billed customers who buy supply elsewhere, divided by their kWh. Not comparable with bundled prices.

Outage minutes above the state average
National Grid's customers averaged 242 minutes without power in 2025 including major storms, more than the New York average of 116 minutes, and 140 minutes excluding major event days. The average customer had 1.39 interruptions, against 0.77 statewide. National Grid reports these figures under the IEEE 1366 standard. Central Hudson, which reports under the same standard, averaged 290 minutes6 including major events.
Where National Grid delivers power
EIA's 2025 service-territory records place National Grid in 37 New York counties, including Albany County, Allegany County, Cattaraugus County, Cayuga County, Chautauqua County, Chenango County, Clinton County, Columbia County, Cortland County, Erie County, Essex County, Franklin County and 25 others. It is the only distribution utility reporting service in 5 of them; in the other 327, at least one other utility also reports customers. A town name is not enough: National Grid's own service map decides by address. With 1,536,569 residential customers on its wires, 20.9% of the state's total, it is New York's second-largest distribution utility after Con Edison. The grid it connects to is run by NYISO1.

Smart meters, rooftop solar and business customers
Advanced meters made up 63.0% of National Grid's residential meters in 2025, against 85.8% across New York. Its customers had 27,577 net-metered rooftop solar installations with 218.2 megawatts of capacity, or 17.9 per 1,000 residential customers, against 33.79 statewide. For the credit given for surplus solar output, see the net metering guide.
Full-service commercial customers paid 15.21¢ per kWh on average in 2025 and industrial customers 9.72¢ per kWh; across all classes the average was 18.11¢ per kWh1.
National Grid's other utility page
The same parent company runs a separate utility in Massachusetts, where full-service residential customers paid 33.66¢ per kWh in 2025, against 19.89¢ per kWh in New York. The two utilities are regulated by different state commissions, and the Massachusetts one is part of ISO New England rather than NYISO1; the National Grid page sets them side by side.

Questions and answers
Is Niagara Mohawk the same as National Grid?
Yes. The utility that delivers electricity to National Grid's upstate New York customers is Niagara Mohawk Power Corporation, which EIA lists under utility number 13573. All figures on this page are EIA's figures for that company in New York.
How much does National Grid charge per kWh in New York?
Full-service residential customers paid an average of 19.89¢ per kWh1 in 2025 and 23.24¢ per kWh2 over the last 12 months (September 2025 to August 2026, 2026 months preliminary). These are averages of everything billed, divided by kWh: customer charge, delivery, supply and adjustments together. They are not a tariff line, and the supply price on any one bill differs from them.
How much did National Grid's rates go up in 2026?
EIA's monthly survey runs to August 20263. In that month the residential average was 22.61¢ per kWh, +22.2%2 against August 2025 (preliminary). On a full-year basis the average rose from 17.22¢ per kWh4 in 2024 to 19.89¢ per kWh1 in 2025.
What is the average National Grid electric bill in upstate New York?
$129.73 a month in 2025 for 652 kWh1, up from $109.744 in 2024. Over the last 12 months (September 2025 to August 2026) it averaged $149.92, with the highest month in January 2026 at $223.412.
