## Charge-by-Charge Breakdown

### Basic Service Charges

#### Customer Charge — $22.50/month

A flat monthly fee that covers the cost of having an account: metering, billing systems, customer service, and distribution-related fixed costs. Everyone on Rate 1 pays it. Central Hudson serves the Mid-Hudson Valley (Ulster, Dutchess, and surrounding counties); the charge is set in NY PSC rate cases.

---

### Delivery Charges

#### Energy Charge — $0.1386/kWh

The main volumetric delivery rate. It recovers the distribution revenue requirement—the cost of the local wires, poles, and transformers. Flat rate: same per-kWh amount regardless of time of day or season. Applies to every kWh you use. Set in Central Hudson's rate cases.

#### Revenue Decoupling Mechanism — _Variable_

Part of NY's decoupling policy: Central Hudson's allowed delivery revenue is decoupled from sales volume. If customers use less than forecast, this charge adjusts so the utility is neutral to conservation. Value from lookup.

#### Transition Adjustment — _Variable_

Recovers legacy costs from New York's electricity restructuring (stranded costs, deferrals). The rate changes as balances are paid down; use the Lookups API for the current value.

#### Purchased Power Adjustment — _Variable_

Reconciles the non-avoidable, variable energy costs from Central Hudson's **remaining generating facilities** and **mandatory IPP (Independent Power Producer) purchases** under legacy PURPA/restructuring-era contracts. Unlike ConEd (which divested all generation), Central Hudson still owns some generating plants and is obligated to purchase power from certain IPPs at predetermined rates. These costs are "non-avoidable" — customers cannot escape them by switching to an ESCO, which is why the charge is classified as delivery (DISTRIBUTION) rather than supply. The base delivery rates embed a forecast; this adjustment reconciles actuals against that forecast monthly. Value from lookup.

#### Electric Bill Credit — _Variable_

A temporary per-kWh credit that returned **$16.351 million** in accumulated regulatory liabilities — money the utility over-collected from customers due to prior rate adjustments. Incorporated into Central Hudson's rate case (Case 24-E-0461), it reduced the requested delivery revenue increase by approximately 32% for the rate year ending June 30, 2025. **Expired June 30, 2025** — for any tariff effective after that date, this value is $0. Value from lookup.

#### Miscellaneous Charges — _Variable_

An **umbrella** that bundles multiple sub-charges into a single $/kWh line item. As of Feb 2025, the aggregate rate is ~$0.00522/kWh. The decomposition (from Central Hudson's published misc charges schedule) includes:

- **Make Whole Factor** ($0.00223/kWh) — regulatory cost reconciliation
- **Arrears Reduction Surcharge** ($0.00185/kWh) — COVID-era arrears forgiveness recovery
- **EV Make Ready Program** ($0.00068/kWh) — EV charging infrastructure costs
- **Miscellaneous Charges II Factor** ($0.00045/kWh) — general delivery cost reconciliation
- **Energy Storage Program Recovery** ($0.00001/kWh) — battery storage program costs
- **Clean Heat Deployment Program** ($0.00000/kWh) — heat pump incentive cost recovery (currently $0)

Also covers: Targeted Demand Response Program, Distributed System Implementation Plan (DSIP), Value Stack Compensation (VDER credits), and Commercial System Relief Program costs. 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.

#### Earnings Adjustment Mechanism Surcharge — _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 Surcharge — _Variable_

A periodic delivery-side cost reconciliation that trues up specific cost categories against what was forecasted in the revenue requirement — including purchased power costs, generation costs, and other delivery expenses. Analogous to ConEd's MAC. Value from lookup.

---

### Supply Charges (MFC and Market Price)

These apply when you take default supply from Central Hudson. The **Merchant Function Charge (MFC)** is split into three components; **market price** components reflect the cost of energy. If you choose an ESCO, you do not pay these supply charges.

#### Allocation of MFC Lost Revenue Charge — _Variable_

Recovers revenue that Central Hudson loses when customers switch to an ESCO or reduce usage (e.g. solar). Allocated across default-supply customers. Value from lookup.

#### Base MFC Supply Charge — _Variable_

The base component of the merchant function charge that covers procurement and supply administration. Only default-supply customers pay it. Value from lookup.

#### MFC Administration Charge — _Variable_

Covers Central Hudson's administrative costs to run default supply service (billing, risk management). Value from lookup.

#### Market Price Charge — _Variable_

The primary pass-through of wholesale energy (commodity) costs. Varies with market prices. Use the Lookups API for the current rate. Only default-supply customers pay it.

#### Market Price Adjustment — _Variable_

A true-up or adjustment to the market price charge (e.g. reconciliation of actual vs. forecast prices). Can be a surcharge or credit. Value from lookup.

---

### Minimum Charge

#### Minimum Charge — $22.50/month

If the bill before applying this floor is less than $22.50, the minimum applies. It equals the customer charge, so the effective floor is "at least the fixed charge." Very low usage or net-generation months can hit the minimum.

---

### Rider Charges and Credits

#### Low Income Bill Discount — tiered

A **discount** (reduction) for qualifying low-income customers. Eligibility is based on enrollment in the company's low-income program (e.g. HEAP, SSI, TANF, SNAP, or Direct Vendor/Utility Guarantee). The tariff has tiers: Electric Heat vs. Non-Electric Heat, and Tier 1–4 within each. Use the `lowIncomeBillDiscount2033` property to determine tier and discount amount. Not applicable for most customers.

#### Customer Benefit Contribution — $1.67/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 **July** using **500 kWh**, default supply, no solar, no LMI discount:

### Delivery Charges

| Charge                | Calculation                 | Amount      |
| --------------------- | --------------------------- | ----------- |
| Customer Charge       | $22.50                      | $22.50      |
| Energy Charge         | 500 kWh × $0.1386           | $69.30      |
| RDM                   | 500 kWh × ~$0.001 (varies)  | ~$0.50      |
| Transition Adj.       | 500 kWh × ~$0.002 (varies)  | ~$1.00      |
| Purchased Power Adj.  | 500 kWh × ~$0.001 (varies)  | ~$0.50      |
| Electric Bill Credit  | (varies; often $0)          | $0.00       |
| Miscellaneous         | 500 kWh × ~$0.001 (varies)  | ~$0.50      |
| SBC                   | 500 kWh × ~$0.004 (varies)  | ~$2.00      |
| EAM Surcharge         | 500 kWh × ~$0.0005 (varies) | ~$0.25      |
| RAM Surcharge         | 500 kWh × ~$0.0005 (varies) | ~$0.25      |
| **Subtotal Delivery** |                             | **~$96.30** |

### Supply Charges

| Charge              | Calculation                | Amount      |
| ------------------- | -------------------------- | ----------- |
| Market Price Charge | 500 kWh × ~$0.07 (varies)  | ~$35.00     |
| Market Price Adj.   | 500 kWh × ~$0.002 (varies) | ~$1.00      |
| MFC Lost Revenue    | 500 kWh × ~$0.001 (varies) | ~$0.50      |
| Base MFC Supply     | 500 kWh × ~$0.002 (varies) | ~$1.00      |
| MFC Admin           | 500 kWh × ~$0.001 (varies) | ~$0.50      |
| **Subtotal Supply** |                            | **~$38.00** |

### Riders & Other

| Charge              | Calculation | Amount    |
| ------------------- | ----------- | --------- |
| CBC (no solar)      | $0          | $0.00     |
| **Subtotal Riders** |             | **$0.00** |

### Total

**~$134.30** for 500 kWh in July, default supply, no solar or LMI. All MFC and market price components are variable; use the Lookups API for a given month. **Minimum** is $22.50; this bill is above that.

### Breakdown by Category

| Category              | Amount  | % of Bill |
| --------------------- | ------- | --------- |
| Fixed Charges         | $22.50  | 17%       |
| Delivery (Volumetric) | ~$73.80 | 55%       |
| Supply                | ~$38.00 | 28%       |
| Riders & Other        | $0.00   | 0%        |

**Key insight**: The single Energy Charge ($0.1386/kWh) is the largest volumetric component; delivery (fixed plus energy and adjustments) makes up most of the bill. Supply is broken into multiple MFC and market price pieces—all variable—so the exact split depends on current lookups.

## Summary: What You Need to Know

1. **Rate 1 is flat** — No TOU, no seasonal delivery tiers in the base energy charge.
2. **MFC** is broken into multiple components (lost revenue, base supply, administration).
3. **Market Price / Purchased Power / Electric Bill Credit** drive variable supply-side amounts.
4. **RDM, Transition, SBC, EAM, RAM** are standard NY adjustment and policy charges.
5. **Low-income** and **CBC** (solar) are eligibility-based.
