**Customer Count**: ~174,396

## Overview

**1-RSS** is **Rochester Gas and Electric (RG&E)'s default residential electric rate**—RG&E Supply Service (RSS). RG&E serves the Rochester, N.Y., area and surrounding counties. Under RSS, customers receive both delivery and default supply from RG&E at a variable supply price; they may alternatively choose an ESCO for supply while keeping RG&E delivery.

This is a **flat, non–time-of-use rate**: one delivery rate and one supply rate (each with possible adjustments) regardless of time of day or season. The tariff includes a customer charge, bill issuance charge, energy delivery charge, make-whole energy component, system benefits charges (energy efficiency and clean energy fund), merchant function charge, transition charge, supply charge, and various NY-mandated riders (revenue decoupling, clean energy standard, rate and earnings adjustment mechanisms, dynamic load management, low-income discount, and customer benefit contribution for solar). **Residential Agricultural Discount** and **Low Income Program Discount** apply when eligibility criteria are met (RAD and HEAP tiers).

## Charge-by-Charge Breakdown

### Basic Service Charges

#### Customer Charge — $23.00/month

A flat monthly fee that covers the cost of having an account: metering, billing systems, customer service. Everyone pays this regardless of usage. RG&E's customer charge is set in rate cases and remains fixed until the next case.

#### Bill Issuance Charge — $0.99/month

Covers the cost of generating and mailing bills and processing payments. Like other NY utilities, RG&E unbundled this from the base customer charge so the recovery of billing costs is transparent. All residential customers pay it.

---

### Delivery Charges

These are charges for using RG&E's distribution network (wires, poles, transformers) in the Rochester area. They are regulated by the NY PSC.

#### Energy Delivery Charge — $0.08316/kWh

The main volumetric delivery rate. It recovers the distribution revenue requirement set in rate cases—the cost of building and maintaining the local grid. This is a flat rate: the same per-kWh amount regardless of time of day or season. It applies to every kWh you use.

#### Make-Whole Energy — $0.00221/kWh

A small, **fixed** per-kWh delivery charge that supplements the base Energy Delivery Charge. In the Arcadia tariff data, it is in the same **"Energy Delivery Charge" rate group** as the base rate ($0.08316/kWh) and classified as DISTRIBUTION — Arcadia treats it as a supplemental component of the base delivery charge, not a separate adjustment. The rate is set in the rate case and remains fixed for the rate-case period (unlike variable true-ups like RDM or RAM). At $0.00221/kWh, it adds ~$1.11/month for a 500 kWh customer. Functionally part of the base delivery rate structure.

#### System Benefits Charge (Energy Efficiency) — _Variable_

Funds energy efficiency programs administered by NYSERDA and related initiatives. The amount is set by the PSC and can change; use the Arcadia Lookups API for current values. All customers pay this as a per-kWh charge on delivery.

#### System Benefits Charge (Clean Energy Fund) — _Variable_

Supports NY's clean energy fund and related programs (renewables, research, low-income energy assistance). Like the energy efficiency component, it is a variable per-kWh delivery charge; current values require a lookup.

#### Transition Charge — _Variable_

Recovers legacy costs from New York's electricity restructuring in the 1990s. These are deferred or stranded costs that utilities are allowed to collect over time. The rate changes as the balance is paid down; use the Lookups API for the current value.

#### Revenue Decoupling Mechanism — _Variable_

Part of NY's decoupling policy: RG&E's allowed delivery revenue is decoupled from sales volume. If customers use less than forecast, this adjustment moves up (and vice versa) so the utility neither gains nor loses from conservation. Typically reconciled on an annual or periodic basis. Value from lookup.

---

### Supply Charges

These charges apply only if you take default supply from RG&E (RSS). If you choose an ESCO, you do not pay RG&E's supply charge or merchant function charge.

#### Merchant Function Charge — _Variable_

Covers RG&E's costs to administer default supply service: procurement, risk management, billing, and related staff and systems. It is a per-kWh charge that varies; use the Lookups API. Only default-supply customers pay it.

#### Supply Charge — _Variable_

The commodity cost of electricity. RG&E purchases power and passes it through at a variable price that reflects market conditions and the utility's supply portfolio. The rate changes frequently (e.g. monthly or as filed); always use the Lookups API for current supply rates.

---

### Clean Energy Standard

#### Renewable Energy Credit — $0.00103/kWh

Recovers the cost of Renewable Energy Credits (RECs) that RG&E or the state acquires to meet NY's clean energy targets. This fixed per-kWh rate is in the tariff; it funds renewable generation support.

#### Zero Emission Credit — $0.00299/kWh

Recovers the cost of Zero Emission Credits (ZECs), which support upstate nuclear plants under NY policy. The rate is fixed in the tariff. All customers pay REC and ZEC as part of the Clean Energy Standard.

---

### Minimum Charge

#### Minimum — $23.99/month

If your total bill (before any taxes or credits) is less than $23.99, you pay $23.99 anyway. The minimum is set at the level of the customer charge plus the bill issuance charge, so RG&E recovers at least the fixed cost of serving the account. Very low usage or net-metered customers may hit this floor.

---

### Rider Charges

Riders are add-on tariff components that apply across rate schedules. They are updated separately from the base rate case.

#### Rate Adjustment Mechanism — $0.00029/kWh

A periodic delivery-side cost reconciliation (defined in PSC No. 120, Section 25 under the Transition Charge umbrella) that trues up specific cost categories: the market value of utility-owned hydro output, net value of purchased power contracts (NUG and NYPA), NYPA Recharge NY residential discount payments, demand response program costs, and transmission wheeling expenses. The mechanism trues them up monthly: each month's charge is set based on a forecast, and any variance is rolled into the next month's rate. At $0.00029/kWh (~$0.15/month for a 500 kWh customer), it is extremely small relative to the base delivery rate. Analogous to ConEd's MAC.

#### Earnings Adjustment Mechanism — $0.000047/kWh

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 RG&E hits its targets, it earns a reward collected from ratepayers at this fixed per-kWh rate (~$0.02/month for a 500 kWh customer — among the smallest line items on the bill); if it doesn't, the EAM would be $0.

#### Dynamic Load Management — $0.000084/kWh

Recovers the cost of RG&E's demand response programs: paying customers or batteries to reduce load during peak periods. Part of NY's grid modernization and reliability efforts. All customers pay this small per-kWh amount.

#### Low Income Program Discount

A bill credit for customers who receive HEAP (Home Energy Assistance Program) benefits. The credit is tiered (Tier 1–4) based on the type of HEAP grant and add-on benefits; see the `lowIncomeHEAPTier` property in the tariff. If you do not receive HEAP, this is $0. Not a charge—a credit that reduces the bill.

#### Customer Benefit Contribution — $1.3056/kW of solar system size

**Only applies to customers with solar panels.** A monthly fee based on your system's nameplate capacity (kW). Created under NY's VDER reforms so solar customers contribute to grid costs. If you do not have solar (`systemSize = 0`), this is $0. Billed per kW of capacity, not per kWh.

#### Residential Agricultural Discount — _Variable_

A credit for customers who qualify under the Residential Agricultural Discount (RAD) program. Eligibility and the credit amount are determined by RG&E and the PSC; the tariff references a lookup or applicability rule. Most residential customers do not receive RAD; if you do not qualify, this line is $0.

## Example Bill Calculation

A customer in July using 500 kWh, with default supply (RSS), no solar, no RAD, and no low-income discount:

### Delivery Charges

| Charge                | Calculation                | Amount      |
| --------------------- | -------------------------- | ----------- |
| Customer Charge       | $23.00                     | $23.00      |
| Bill Issuance Charge  | $0.99                      | $0.99       |
| Energy Delivery       | 500 kWh × $0.08316         | $41.58      |
| Make-Whole Energy     | 500 kWh × $0.00221         | $1.11       |
| SBC (EE + CEF)        | 500 kWh × ~$0.004 (varies) | ~$2.00      |
| Transition Charge     | 500 kWh × ~$0.001 (varies) | ~$0.50      |
| Revenue Decoupling    | 500 kWh × ~$0.001 (varies) | ~$0.50      |
| **Subtotal Delivery** |                            | **~$69.68** |

### Supply Charges

| Charge              | Calculation                | Amount      |
| ------------------- | -------------------------- | ----------- |
| Supply Charge       | 500 kWh × ~$0.07 (varies)  | ~$35.00     |
| Merchant Function   | 500 kWh × ~$0.002 (varies) | ~$1.00      |
| **Subtotal Supply** |                            | **~$36.00** |

### Riders & Other

| Charge              | Calculation         | Amount     |
| ------------------- | ------------------- | ---------- |
| REC                 | 500 kWh × $0.00103  | $0.52      |
| ZEC                 | 500 kWh × $0.00299  | $1.50      |
| RAM                 | 500 kWh × $0.00029  | $0.15      |
| EAM                 | 500 kWh × $0.000047 | $0.02      |
| DLM                 | 500 kWh × $0.000084 | $0.04      |
| CBC (no solar)      | $0                  | $0.00      |
| **Subtotal Riders** |                     | **~$2.23** |

### Total

**~$107.91** for 500 kWh (assuming approximate variable rates above). Supply and some delivery components (SBC, transition, RDM, MFC) vary; use the Lookups API for a given month. Minimum charge is $23.99; this example is well above that.

### Breakdown by Category

| Category              | Amount  | % of Bill |
| --------------------- | ------- | --------- |
| Fixed Charges         | $23.99  | 22%       |
| Delivery (Volumetric) | ~$45.69 | 42%       |
| Supply                | ~$36.00 | 33%       |
| Riders & Other        | ~$2.23  | 2%        |

**Key insight**: On 1-RSS, delivery (fixed plus volumetric) and supply each make up a large share of the bill. The flat delivery rate and fixed REC/ZEC/RAM/EAM/DLM amounts make the bill easy to approximate for a given usage once supply and variable delivery components are known from lookups.
