Overview
A-16 is Rhode Island Energy (RIE) default residential electric rate. Rhode Island Energy (formerly National Grid – Rhode Island) serves the state of Rhode Island. A-16 is the basic residential rate for most homes, including church and farm customers. Bills are split into delivery (RIE) and supply (default Last Resort Service or competitive supplier).
This is a flat, non-TOU rate. Delivery components in the tariff include: customer charge, distribution charge, operating & maintenance (O&M) and O&M reconciliation, CapEx factor and reconciliation, RDM adjustment, pension adjustment, storm fund replenishment, arrearage management adjustment, low-income discount recovery, performance incentive, last resort adjustment, net metering charge, long-term contracting charge, renewable energy distribution charge, RE growth charge, LIHEAP enhancement charge, transmission charge, transition charge, energy efficiency programs charge, standard offer service (supply), minimum, renewable standard energy charge, and gross earnings tax. Many delivery components use variable factors (lookups) for true-ups and policy adjustments.

Charge-by-Charge Breakdown
Basic Service Charges
Customer Charge — $6.00/month
A flat monthly fee that covers the cost of having an account: metering, billing systems, customer service. Everyone on A-16 pays it. Rhode Island Energy (formerly National Grid – Rhode Island) serves the state of Rhode Island; the charge is set in RI PUC rate cases. One of the lower customer charges among default residential rates in the region.
Delivery Charges
Delivery charges recover the cost of the distribution grid, transmission, and state-mandated programs. Many components use variable factors (lookups) that the utility updates periodically. Regulated by the RI PUC.
Distribution Charge — $0.0458/kWh
The main volumetric distribution rate. Recovers the cost of the local wires, poles, and transformers. Flat rate; applies to every kWh. Set in RIE's rate cases.
Operating & Maintenance Exp Charge — $0.00223/kWh
Recovers day-to-day O&M costs for the distribution system. Fixed per-kWh rate in the tariff. All delivery customers pay it.
O&M Reconciliation Factor — Variable
True-up that reconciles actual O&M costs with the amount collected under the fixed O&M charge. Can be a small surcharge or credit. Value from lookup.
CapEx Factor Charge — $0.00832/kWh
Recovers capital expenditure (infrastructure investment) for the distribution system. Fixed per-kWh rate in the tariff.
CapEx Reconciliation Factor — Variable
True-up for capital cost recovery. Value from lookup. Ensures allowed CapEx recovery matches actual spending.
RDM Adjustment Factor — Variable
Revenue decoupling mechanism: RIE's allowed delivery revenue is decoupled from sales so the utility is neutral to conservation. This factor adjusts for differences between actual and forecast usage. Value from lookup.
Pension Adjustment Factor — $0.00339/kWh
Recovers pension and benefit costs for distribution employees. Fixed per-kWh rate in the tariff. Part of labor-related cost recovery.
Storm Fund Replenishment Factor — Variable or $0
Recovers or replenishes storm-related costs (e.g. restoration, reserves). May be zero or a small amount; value from lookup when applicable.
Arrearage Management Adjustment Factor — $0.00006/kWh
Recovers costs of arrearage management programs (payment plans, forgiveness programs). Very small fixed per-kWh rate. All customers pay it.
Low-Income Discount Recovery Factor — $0.00251/kWh
Recovers the cost of low-income bill discounts from non-participating customers. Spreads the cost of assistance programs across the rate base. Fixed per-kWh rate in the tariff.
Performance Incentive Factor — Variable or $0
Ties delivery rates to performance metrics (e.g. reliability, customer service). May be a surcharge or credit. Value from lookup when applicable.
Last Resort Adjustment Factor — Variable or $0
Delivery-side adjustment related to Last Resort (default) supply; may true-up costs. Value from lookup when applicable.
Net Metering Charge — $0.01457/kWh
Recovers the cost of net metering programs (solar and other DER). Spread across all customers. Fixed per-kWh rate in the tariff. Part of RI's renewable and distributed energy policy.
Long Term Contracting Charge — Variable
Recovers costs of long-term supply or capacity contracts that support reliability or clean energy. Value from lookup.
RE Growth Charge — Variable
Fixed monthly (or quantity-based) charge that supports renewable energy growth programs. Value from lookup.
LIHEAP Enhancement Charge — Variable
Supports the Low-Income Home Energy Assistance Program (LIHEAP). Typically a small fixed monthly amount or factor. Value from lookup.
Transmission Charge — $0.04773/kWh
Recovers the cost of high-voltage transmission (getting power to the distribution grid). Set by FERC or state; passed through to customers. Fixed per-kWh rate in the tariff. Often one of the larger delivery line items.
Transition Charge — $0.00001/kWh
Recovers legacy restructuring or transition costs. Very small fixed per-kWh rate in the tariff.
Energy Efficiency Programs Charge — Variable
Recovers the cost of energy efficiency programs (e.g. rebates, incentives) mandated by the state. All customers pay. Value from lookup.
Supply Charges
These apply only if you take default supply (Last Resort Service / Standard Offer) from RIE. If you choose a competitive supplier, you do not pay RIE's supply charges.
Standard Offer Service Charge — Variable
The default supply (commodity) rate for customers who do not choose a competitive supplier. Often updated monthly to reflect wholesale prices. Use the Lookups API for the current rate. This is typically the largest variable component of the bill for default-supply customers.
Renewable Standard Energy Charge — Variable
Recovers the cost of meeting Rhode Island's renewable/clean energy requirements on the supply side (e.g. RECs). Value from lookup. Only default-supply customers pay it.
Minimum Charge
Minimum — $6.00/month
If the bill before applying this floor is less than $6.00, the minimum applies. It equals the customer charge. Very low usage or net-generation months can hit the minimum.
Taxes and Other
Gross Earnings Tax — $4.166667 (quantity-based)
State (and/or local) gross earnings tax on utility revenue, passed through to customers. The tariff shows a quantity-based value (e.g. applied as a factor or fixed amount per month). Use the tariff or Lookups API for how it applies to your bill. Typically a few dollars per month.
Example Bill Calculation
A customer in July using 500 kWh, default supply (Standard Offer), secondary connection:
Delivery Charges
| Charge | Calculation | Amount |
|---|---|---|
| Customer Charge | $6.00 | $6.00 |
| Distribution | 500 kWh × $0.0458 | $22.90 |
| O&M Exp | 500 kWh × $0.00223 | $1.12 |
| O&M Recon | (varies) | ~$0.20 |
| CapEx Factor | 500 kWh × $0.00832 | $4.16 |
| CapEx Recon | (varies) | ~$0.20 |
| RDM Adj | (varies) | ~$0.30 |
| Pension Adj | 500 kWh × $0.00339 | $1.70 |
| Storm Fund | (varies) | ~$0.10 |
| Arrearage Mgmt | 500 kWh × $0.00006 | $0.03 |
| LMI Recovery | 500 kWh × $0.00251 | $1.26 |
| Net Metering | 500 kWh × $0.01457 | $7.29 |
| Long Term Contracting | (varies) | ~$0.50 |
| RE Growth | (varies) | ~$0.50 |
| LIHEAP | (varies) | ~$0.25 |
| Transmission | 500 kWh × $0.04773 | $23.87 |
| Transition | 500 kWh × $0.00001 | $0.01 |
| EE Programs | (varies) | ~$2.50 |
| Subtotal Delivery | ~$71.89 |
Supply Charges
| Charge | Calculation | Amount |
|---|---|---|
| Standard Offer | 500 kWh × ~$0.08 (varies) | ~$40.00 |
| Renewable Standard | 500 kWh × ~$0.002 (varies) | ~$1.00 |
| Subtotal Supply | ~$41.00 |
Other (Taxes)
| Charge | Calculation | Amount |
|---|---|---|
| Gross Earnings Tax | (quantity-based) | ~$4.17 |
| Subtotal Other | ~$4.17 |
Total
~$117.06 for 500 kWh in July, default supply. Many delivery factors and Standard Offer are variable; use the Lookups API for a given month. Minimum is $6.00; this bill is above that.
Breakdown by Category
| Category | Amount | % of Bill |
|---|---|---|
| Fixed Charges | $6.00 | 5% |
| Delivery (Volumetric) | ~$65.89 | 56% |
| Supply | ~$41.00 | 35% |
| Other (e.g. GET) | ~$4.17 | 4% |
Key insight: Delivery has many line items—distribution, transmission, O&M, CapEx, net metering, RDM, and various factors—so the delivery section is granular. Transmission ($0.04773/kWh) and distribution ($0.0458/kWh) are the largest fixed-rate delivery components. Standard Offer (supply) is variable and often a large share of the total; the exact bill depends heavily on current lookup values and the default supply rate.

Understanding the JSON
- chargeType: FIXED_PRICE, CONSUMPTION_BASED, QUANTITY, MINIMUM.
- chargeClass: DISTRIBUTION, SUPPLY, CONTRACTED, TRANSMISSION where applicable.
- variableRateKey / variableFactorKey: Use Arcadia Lookups API for current values.
- properties: connectionType, phase, consumption, chargeClass.
Summary: What You Need to Know
- A-16 is flat — No TOU; single delivery and supply rate structure.
- Delivery includes many adjustment factors (RDM, pension, storm, arrearage, LMI, performance, last resort, etc.)—often lookups.
- Supply: Standard Offer Service (Last Resort Service); variable; customers may choose competitive supply.
- RE, LIHEAP, EE, transmission, transition are standard RI policy and program charges.
