Overview
SC1 is National Grid – New York (Niagara Mohawk) default residential electric rate—Residential and Farm. National Grid serves Upstate New York across multiple zones: Adirondack, Capital, Central, Frontier, Genesee, and Utica. Delivery and supply rates are zone-specific; the tariff has many rate entries for each zone and for supply/delivery adjustments.
This is a flat, non-TOU rate: no time-of-use differentiation. Charges include customer charge, energy (delivery) charge, income-eligible basic service credit, revenue decoupling (RDM), transmission revenue adjustment, legacy transition charge, electricity supply charge (by zone), SBC, Clean Energy Standard (supply and delivery), dynamic load management, earnings adjustment mechanism, minimum, merchant function charge, GreenUp rider (optional), CBC, EV Make Ready, arrears management recovery, net utility plant/depreciation reconciliation, and rate adjustment mechanism. Low-income and GreenUp are optional/eligibility-based (see properties).

Charge-by-Charge Breakdown
National Grid serves Upstate New York across six zones: Adirondack, Capital, Central, Frontier, Genesee, and Utica. The base customer and energy charges are the same everywhere; zone-specific delivery and supply adjustments (Delivery Charge Adjustment and Electric Supply Charge by zone) apply on top. Use the tariff or Lookups API with the correct zone (territoryId) to get delivery and supply amounts for your location.
Basic Service Charges
Basic Service Charge — $19.00/month
A flat monthly fee that covers the cost of having an account: metering, billing systems, customer service. Everyone on SC1 pays it. Same in all zones. Set in National Grid's NY PSC rate cases.
Income Eligible Basic Service Credit — tiered (credit)
A credit (reduction) for qualifying low-income customers. Eligibility and tier determine the amount. Not applicable for most customers; when applicable it reduces the basic service (and possibly other) charges. Use the tariff applicability for income-eligible tiers.
Delivery Charges
Energy Charge — $0.08889/kWh
The main volumetric delivery rate. Recovers the distribution revenue requirement—the cost of the local wires, poles, and transformers. Flat rate; same in all zones. Applies to every kWh. Set in National Grid's rate cases.
Delivery Charge Adjustment — Variable, by zone
In the Arcadia tariff data, this is an umbrella (riderId 801) that bundles two distinct components for each of National Grid's six zones (12 sub-rates total):
- Delivery Charge Adjustment - [Zone] (chargeClass: DISTRIBUTION): A zone-specific adjustment to the base delivery energy charge ($0.08889/kWh is uniform; this adds zone-level differentiation reflecting differing infrastructure costs).
- Electricity Supply Charge - [Zone] (chargeClass: SUPPLY,CONTRACTED): The zone-specific default supply charge — National Grid's equivalent of ConEd's MSC, recovering wholesale energy costs for customers on default supply.
Use the Lookups API with the correct zone (territoryId) to get both the delivery adjustment and the supply rate for your location.
Revenue Decoupling Mechanism — Variable
Part of NY's decoupling policy: National Grid's allowed delivery revenue is decoupled from sales. This charge adjusts so the utility is neutral to conservation. Value from lookup.
Transmission Revenue Adjustment — Variable
Reconciles National Grid's actual transmission costs with the transmission cost component embedded in retail delivery rates. Unlike distribution costs (set in PSC rate cases), National Grid's transmission costs are governed by a FERC-approved formula rate under the NYISO Open Access Transmission Tariff (established in a 2009 Settlement Agreement). This formula updates annually based on actual investment return, depreciation, and property tax on transmission plant. The TRA adjusts residential bills so customers pay the current FERC-formula amount rather than whatever was frozen in the last state rate case. Value from lookup.
Legacy Transition Charge — Variable
Recovers legacy costs from New York's electricity restructuring (stranded costs, deferrals). Value from lookup.
System Benefits Charge — Variable
Funds NY clean energy and efficiency programs (e.g. NYSERDA). Set by the PSC; all customers pay. Rate from lookup.
Clean Energy Standard — Delivery Charge — Variable
Recovers National Grid's delivery-side costs to comply with NY's Clean Energy Standard (RECs, ZECs, distribution compliance). Value from lookup.
Dynamic Load Management Surcharge — Variable
Recovers the cost of demand response and dynamic load management programs. Value from lookup.
Earnings Adjustment Mechanism — Variable
A performance-based incentive created by the NY PSC under REV (Reforming the Energy Vision). The EAM is not a cost recovery mechanism or earnings true-up — it is a bonus paid to the utility for achieving specific policy-outcome targets (e.g., peak reduction, DER utilization, beneficial electrification, energy efficiency). If the utility hits its targets, it earns a reward collected from ratepayers as a uniform $/kWh surcharge; if it doesn't, the EAM is $0. Typically a very small per-kWh amount. Value from lookup.
Rate Adjustment Mechanism — $0.00671/kWh
A periodic delivery-side cost reconciliation that trues up specific cost categories against what was forecasted in the revenue requirement — including purchased power costs, hydro output, NUG contract costs, demand response program costs, and transmission wheeling expenses. Analogous to ConEd's MAC. Fixed in the tariff at this rate; all delivery customers pay it.
Electric Vehicle Make Ready Surcharge — $0.00147/kWh
Recovers National Grid's costs for EV charging infrastructure (make-ready conduit and wiring). Part of NY's EV infrastructure push. All customers pay this per-kWh amount.
Arrears Management Program Recovery Surcharge — $0.00087/kWh
Recovers costs of arrears management and forgiveness programs. Fixed per-kWh rate in the tariff. All customers pay it.
Net Utility Plant and Depreciation Expense Reconciliation — Variable or $0
Trues up the difference between National Grid's actual capital spending and the capital budget approved in the rate case. Base rates embed an expected return on (investment return on rate base) and return of (depreciation expense) for planned capital. If the utility spends less than approved, customers receive a credit for the over-collection; if it spends more (with PSC approval), customers are surcharged. Currently near $0, suggesting the forecast and actuals are well-aligned. Value from lookup when applicable.
Supply Charges
These apply only if you take default supply from National Grid. Supply is zone-specific: each zone has its own Electric Supply Charge (and related MFC components). If you choose an ESCO, you do not pay these supply charges.
Electricity Supply Charge — Variable, by zone
The default supply (commodity) rate. Varies by zone: Adirondack, Capital, Central, Frontier, Genesee, and Utica each have their own supply rate because wholesale and delivery costs differ. Use the Lookups API with your zone (territoryId) to get the current supply rate.
Electricity Supply Reconciliation Mechanism — Variable, by zone
A supply-side true-up that reconciles actual supply costs with the amount collected. Zone-specific. Value from lookup.
Clean Energy Standard — Supply Charge — Variable
Recovers the supply-side cost of meeting NY's Clean Energy Standard (RECs, ZECs). Only default-supply customers pay it. Value from lookup.
Merchant Function Charge — Working Capital on Purchased Power / Uncollectible Expense / Procurement / Credit and Collection — Variable, by zone or global
Covers National Grid's costs to administer default supply: working capital on purchased power (zone-specific), uncollectible expense (zone-specific and one global component), procurement, and credit/collection. Multiple line items in the tariff; all are variable. Use the Lookups API for your zone. Only default-supply customers pay MFC.
Minimum Charge
Minimum — $19.00/month
If the bill before applying this floor is less than $19.00, the minimum applies. It equals the basic service charge. Very low usage or net-generation months can hit the minimum.
Rider Charges (Optional and Mandatory)
GreenUp Charge — tiered (optional)
Only if you opt in to the GreenUp program (greenUpProgramChoice ≠ "None"). Voluntary renewable energy product (e.g. NewWind, EnviroGen, Sterling Green). If you do not opt in, this is $0. Tiered by product choice; use the tariff for the rate that applies to your selection.
Customer Benefit Contribution — $0.97/kW of system size (solar)
Only applies to customers with solar. A monthly charge based on nameplate capacity (kW). Part of NY's VDER reforms so solar customers contribute to grid costs. If you do not have solar, this is $0.
Example Bill Calculation
A customer in the Central zone in July using 500 kWh, default supply, no solar, no GreenUp:
Delivery Charges
| Charge | Calculation | Amount |
|---|---|---|
| Basic Service | $19.00 | $19.00 |
| Energy Charge | 500 kWh × $0.08889 | $44.45 |
| Delivery Adj (Central) | 500 kWh × ~$0.002 (varies by zone) | ~$1.00 |
| RDM | 500 kWh × ~$0.001 (varies) | ~$0.50 |
| Transmission Rev Adj | 500 kWh × ~$0.002 (varies) | ~$1.00 |
| Legacy Transition | 500 kWh × ~$0.001 (varies) | ~$0.50 |
| SBC | 500 kWh × ~$0.004 (varies) | ~$2.00 |
| CES Delivery | 500 kWh × ~$0.003 (varies) | ~$1.50 |
| DLM Surcharge | 500 kWh × ~$0.0002 (varies) | ~$0.10 |
| EAM | 500 kWh × ~$0.0005 (varies) | ~$0.25 |
| RAM | 500 kWh × $0.00671 | $3.36 |
| EV Make Ready | 500 kWh × $0.00147 | $0.74 |
| Arrears Recovery | 500 kWh × $0.00087 | $0.44 |
| Subtotal Delivery | ~$74.29 |
Supply Charges
| Charge | Calculation | Amount |
|---|---|---|
| Supply (Central) | 500 kWh × ~$0.07 (varies by zone) | ~$35.00 |
| Supply Recon | (varies by zone) | ~$0.50 |
| CES Supply | 500 kWh × ~$0.003 (varies) | ~$1.50 |
| MFC (Working Cap, Uncollectible, Procurement, etc.) | (varies by zone) | ~$2.00 |
| Subtotal Supply | ~$39.00 |
Riders & Other
| Charge | Calculation | Amount |
|---|---|---|
| GreenUp (none) | $0 | $0.00 |
| CBC (no solar) | $0 | $0.00 |
| Subtotal Riders | $0.00 |
Total
~$113.29 for 500 kWh in July, Central zone, default supply, no solar or GreenUp. Zone-specific delivery adjustment and supply (and MFC) will differ by zone; use the Lookups API for your zone and month. Minimum is $19.00; this bill is above that.
Breakdown by Category
| Category | Amount | % of Bill |
|---|---|---|
| Fixed Charges | $19.00 | 17% |
| Delivery (Volumetric) | ~$55.29 | 49% |
| Supply | ~$39.00 | 34% |
| Riders & Other | $0.00 | 0% |
Key insight: Delivery (fixed plus energy and zone-specific adjustment plus RDM, SBC, CES, RAM, EV, etc.) and supply each contribute a large share. The same 500 kWh in a different zone (e.g. Adirondack, Frontier) will have a different total because both delivery adjustment and supply rates are zone-specific. RAM and EV Make Ready are fixed per-kWh riders that are visible on the bill; the rest depend on lookups.
