In 2025, 67% of the commercial kWh delivered by National Grid (Niagara Mohawk) went to customers buying energy from a competitive supplier, and 33% stayed on the utility's default service. By customer count it is 29%, because the businesses that shop tend to be the larger ones.

National Grid (Niagara Mohawk)’s delivery charges averaged 4.51¢ per kWh across its 53,705 delivery-only commercial customers: the part of the bill no supplier can change. It is an average over customers of every size. Large customers pay far less per kWh than small ones, so your own delivery charge per kWh will differ; the average customer here used about 13,091 kWh a month.

National Grid (Niagara Mohawk) customers went without power for an average of 140 minutes in 2025, excluding major storms, with about 1.11 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes.

EIA records National Grid (Niagara Mohawk) serving customers in 37 New York counties: Albany, Allegany, Cattaraugus, Cayuga, Chautauqua, Chenango, Clinton, Columbia, Cortland, Erie, Essex, Franklin, Fulton, Genesee, and 23 more. A county can be shared between utilities, so this does not tell you who serves a given address.

What National Grid (Niagara Mohawk) controls and what it does not

Cities and areas in this territory

Territory boundaries do not follow city limits. Two addresses on the same street can sit in different territories, which is why we confirm the Account number rather than inferring eligibility from the city or the ZIP code. Inferring from location is the most common way a commercial account is told it can do something it cannot.

Which lever moves which charge

This is the question a utility page exists to answer. If you change something at the meter, which line on the bill actually moves — and which one does not move no matter what you do?

Fixed customer chargeNothing you do

A flat monthly amount for being connected. It does not move with consumption or with peak.

No lever

Volumetric distributionHow much you use

Charged per kilowatt-hour. This is the line that efficiency work moves.

Use less

Demand chargeHow hard you draw

Charged per kilowatt of billed demand. Set by your highest interval, not by your total — which is why cutting consumption may not move it at all.

Lower the peak

Riders and surchargesRegulatory filings

Adjusted periodically through approved filings. They step rather than scale, and nothing you do at the meter changes them.

No lever

Schematic shapes, not National Grid (Niagara Mohawk)'s actual rates — those come from the filed tariff. The point is the behaviour: two of these four respond to something you control, and a supplier changes none of them.

What sits inside the delivery charge from National Grid (Niagara Mohawk)

Delivery is not one number. On a commercial account it is typically assembled from several components, each set by the filed tariff and each behaving differently as your usage changes:

• A fixed customer or meter charge, which does not move with consumption at all.
• A volumetric distribution charge per kWh, which scales with how much you use.
• A demand charge per kW where the account is demand-metered, which scales with how hard you draw rather than how much you use — and which is where a low load factor account gets hurt.
• Riders and surcharges, adjusted periodically through regulatory filings, covering items such as transmission cost recovery, energy efficiency programs and storm or system restoration costs.

None of these changes when you change supplier. Understanding the mix matters because it determines which action actually moves your bill: reducing consumption attacks the volumetric component, reducing peak draw attacks the demand component, and neither one touches the fixed charge.

Boundaries do not follow city limits. If you are not certain which of these serves your address, confirm the Account number printed on the bill rather than inferring it from the city.

What the National Grid (Niagara Mohawk) tariff says: SC 2 Small General Service and SC 3 Large General Service (delivery voltage 0-2.2 kV)

Read 2026-10-31 from Niagara Mohawk Power Corporation d/b/a National Grid, P.S.C. No. 220 Electricity, Service Classifications No. 2 and No. 3: rate Leaves 370, 371 and 379, initial effective date April 1, 2026; demand and applicability rules on Leaves 372, 378 and 381, initial effective dates September 1, 2025, February 1, 2026 and March 1, 2026. Each figure is quoted from that document, and it is a schedule figure, not a bill estimate. See every tariff quoted on this site. The tariff and the schedule code on your bill control what applies to you.

Who SC 2 covers

SC 2 (Small General Service) covers all purposes with no other class specifically provided, where the entire requirements are delivered at one point and singly metered. A customer stays on it until monthly measured demand exceeds 100 kW for twelve consecutive months after the initial term, except as Special Provision I provides.

SC 2 service charges

Metered non-demand service, all load zones: Basic Service Charge $25.00, distribution delivery $0.11345 per kWh and Monthly Minimum Charge $25.00. Metered demand service, all load zones: Basic Service Charge $65.00, Distribution Delivery Charges $18.93 per kW and Monthly Minimum Charge $83.93. Customers under Special Provisions O and P are printed with separate, higher figures.

How SC 2 demand is set

A demand meter is installed whenever monthly use for any four consecutive months exceeds 2000 kWh per month, or the connected load indicates it will. The Distribution Delivery demand is the highest average kW measured in a fifteen-minute interval during the billing period, but not less than one kW nor less than the demand contracted for.

Who SC 3 covers

SC 3 (Large General Service) applies when monthly measured demand has equaled or exceeded 100 kW in each of the previous twelve months, or when in the Company's opinion the applicant's demand will equal or exceed 100 kW in twelve consecutive months.

SC 3 charges at 0-2.2 kV

At delivery voltage 0-2.2 kV the Customer Charge (Distribution Delivery) is $870.00. The demand charges are $624.80 for the first 40 or less kW of demand and $15.62 per kW for all kW of demand over 40. The same table prints separate figures for 2.2-15 kV, 22-50 kV and Over 60 kV.

How SC 3 demand is set

For delivery voltage up to 2.2 kV and 2.2-15 kV the demand is the highest kW measured over any fifteen minute interval during the month, but not less than one-half of the highest such demand in any of the preceding eleven months, nor less than the demand contracted for. The monthly minimum charge is the charge computed under the Monthly Rate.

Billed separately

Not in these figures: adjustments such as the System Benefits Charge (Rule 41), Merchant Function Charge (Rule 42), Transmission Revenue Adjustment (Rule 43) and Revenue Decoupling Mechanism (Rule 57), and electricity supply, which is set by the market price under Rule 46.1. The tariff increases the rates and charges, including minimum charges, by a tax factor under Rule 32.

• The delivery and supply sections, kept separate
• Current supplier and contract expiry, if any
