Overview

SC4 is ConEd's demand-based rate available to any residential customer who wants it. Unlike SC1 and SC3 which charge primarily based on energy consumption (kWh), SC4 includes significant demand charges ($/kW) based on your peak power draw. While open to all, it's particularly well-suited for customers with heat pumps—especially geothermal systems—that have high, steady loads.

What is a Demand Charge?

Demand charges are based on your peak power usage (kW), not total energy consumption (kWh):

Concept	Energy (kWh)	Demand (kW)
What it measures	Total electricity used over time	Maximum instantaneous power draw
Analogy	Miles driven	Top speed reached
Billing period	Sum of all usage	Highest 60-minute average
Units	kilowatt-hours	kilowatts

Why demand charges exist: The utility must build infrastructure to handle your peak load. A customer who uses 1,000 kWh spread evenly over a month costs less to serve than one who uses 1,000 kWh in concentrated bursts. Demand charges recover infrastructure costs more fairly.

Key Differences from SC1 and SC3

Aspect	SC1 (Default)	SC3 (Vol. TOU)	SC4 (Demand-Based)
TOU	No	Yes	Yes
Tiering	Yes	No	Partial (delivery adjustments)
Demand Charges	No	No	Yes
Applicability	Everyone	Opt-in	Opt-in
Energy Input	`consumption`	`consumption[ON_PEAK/OFF_PEAK]`	`consumption`
Demand Input	N/A	N/A	`demand[ON_PEAK/OFF_PEAK]`

Who This Rate is For

SC4 is an opt-in rate available to any residential customer who wants demand-based billing. It may be particularly attractive for:

Customers with geothermal heat pumps — high, steady loads benefit from demand pricing
EV owners with managed charging — can shift charging to off-peak hours
Homes with battery storage — can flatten demand peaks
Customers with predictable, consistent usage patterns

The tariff includes a hasGeothermalHeatPumps property that may affect certain rate applicability rules, but geothermal is not required to enroll.

Understanding SC4's Demand Calculation

How Billing Demand is Calculated

SC4 uses a specific formula for billing demand:

The Billable Demands shall be determined by calculating the average of the three highest maximum daily demands occurring in each time period for the applicable billing period. All maximum daily demand values shall be established by calculating the highest integrated 60-minute demand ending in each day and being entirely comprised of intervals ending in the same time period (on-peak, off-peak).

Step by step:

For each day in the billing period, find the highest 60-minute average demand during on-peak hours
Take the three highest daily values
Average them → This is your On-Peak Billing Demand
Repeat for off-peak hours → Off-Peak Billing Demand

Example Calculation

Day	Max 60-min On-Peak (kW)	Max 60-min Off-Peak (kW)
Day 1	4.2	2.1
Day 2	3.8	1.9
Day 3	5.1	2.3
Day 4	4.5	2.0
Day 5	3.9	2.2
...	...	...

On-Peak Billing Demand = Average of 3 highest = (5.1 + 4.5 + 4.2) / 3 = 4.6 kW Off-Peak Billing Demand = Average of 3 highest = (2.3 + 2.2 + 2.1) / 3 = 2.2 kW

This averaging smooths out single-day spikes, but still incentivizes consistent load management.

TOU Schedule

SC4 uses a different TOU schedule than SC3. On-peak hours are more limited:

Schedule Summary

Period	Hours	Days
On-Peak	12:00 PM – 8:00 PM	Sun – Thu
Off-Peak	All other hours	Sun – Thu
Off-Peak	All day	Fri – Sat

Key differences from SC3:

SC3 on-peak: 8am–midnight, all days
SC4 on-peak: 12pm–8pm, Sun–Thu only
SC4 treats Friday and Saturday as entirely off-peak

Visual Schedule

           12am  4am   8am  12pm  4pm   8pm   12am
Sun-Thu   |←───── OFF-PEAK ─────→|← ON-PEAK →|← OFF-PEAK →|
Fri-Sat   |←─────────────── ALL OFF-PEAK ──────────────→|

This schedule benefits customers who can shift high-demand activities to:

Evenings after 8pm
Early mornings before noon
Fridays and Saturdays (all day)

Charge-by-Charge Breakdown

Basic Service Charges

Customer Charge — $29.00/month

A flat monthly fee that covers the cost of having an account. Higher than SC1/SC3 ($20/mo) because demand metering and billing is more complex. Everyone pays this regardless of usage.

Billing and Payment Processing Charge — $1.28/month

Covers the cost of generating and mailing bills, processing payments. Same as other tariffs.

Demand Charges

These are the core differentiator of SC4. Based on your peak power draw (kW), not energy consumption (kWh).

Summer On-Peak Demand — $25.36/kW

The most expensive demand charge. Applied to your on-peak billing demand during summer months (June–September). This reflects the infrastructure costs of serving peak summer loads when air conditioning strains the grid.

Summer Off-Peak Demand — $7.48/kW

Applied to your off-peak billing demand during summer. Significantly lower than on-peak, rewarding customers who can shift high-power activities to nights, early mornings, and weekends.

Winter On-Peak Demand — $19.50/kW

Applied to your on-peak billing demand during winter months (October–May). Lower than summer because winter peak demand is typically less grid-straining than summer.

Winter Off-Peak Demand — $7.48/kW

Same rate year-round for off-peak demand. The consistent off-peak rate creates a predictable floor.

Delivery Adjustments

Same variable-rate adjustments as SC1/SC3, applied to total consumption (not split by TOU):

📘 Deep Dive: For regulatory background and calculation details, see Delivery Adjustments Guide.

Monthly Adjustment Clause (MAC) — Variable Umbrella adjustment for property taxes, storm costs, pension expenses.

Revenue Decoupling Mechanism (RDM) Adjustment — Variable True-up for actual vs. expected sales volume.

Delivery Revenue Surcharge — Variable Supplemental revenue adjustment.

Clean Energy Standard Delivery Surcharge — Variable Grid infrastructure costs for clean energy compliance.

Reconciliation Rate — Variable Legacy deferred costs from 1990s restructuring.

Transition Adjustment — Variable Legacy deregulation costs.

Uncollectible Bill Expense — Variable Bad debt recovery.

Temporary Rate Adjustment — Credit, varies by zone/season A tiered credit that reduces delivery costs. Zone and season-specific.

Supply Charges

Same as SC1/SC3—charges for the electricity commodity itself. Only apply if using ConEd as supplier.

📘 Deep Dive: For NYISO settlement, load-weighted averaging, and reconciliation details, see Supply Charges Guide.

MSC Rate (Market Supply Charge) — Variable, by zone Base cost of electricity, forecasted monthly from wholesale prices.

MSC I Adjustment — Variable, by zone Reconciles actual energy costs vs. forecast.

MSC II Adjustment — Variable Reconciles capacity costs and ancillary services.

Clean Energy Standard Supply Surcharge — Variable RECs, ZECs, and other clean energy compliance costs.

Merchant Function Charge — Variable ConEd's costs to administer supply service.

System Benefits Charge

System Benefits Charge (SBC) — Variable

Funds NY's clean energy programs administered by NYSERDA.

NY State Surcharge

New York State Surcharge — Variable

Temporary surcharge for policy initiatives or one-time cost recovery.

Minimum Charge

Minimum Charge — $29.00/month

If your total bill is less than $29, you pay $29 anyway. Higher than SC1/SC3 ($20) to match the higher customer charge.

Rider Charges

Same riders as SC1/SC3. See Riders Guide for full details.

Tax Sur-Credit — Variable

Tax cost true-ups. Can be positive or negative.

Dynamic Load Management (DLM) Surcharge — Variable

Demand response program costs.

Customer Benefit Contribution (CBC) — $1.84/kW

Electric Vehicle Make Ready Surcharge — $0.0008/kWh

EV charging infrastructure costs.

Arrears Management Program Recovery Surcharge — $0.0012/kWh

COVID-era arrears recovery.

Gross Receipts Tax (GRT) — Varies by zone

Municipal taxes on utilities:

Zone	GRT Distribution	GRT Supply
H (Upper Westchester)	3.3322%	1.0101%
I (Lower Westchester)	5.5127%	3.0928%
J (NYC)	4.7940%	2.4066%

VDER Cost Recovery — $0.0011/kWh

Costs ConEd pays to solar generators under Value Stack.

Example Bill Calculation

A Zone J customer in July (Summer) with:

Total consumption: 800 kWh
On-Peak Billing Demand: 5 kW
Off-Peak Billing Demand: 3 kW

Fixed Charges

Charge	Calculation	Amount
Customer Charge	$29.00	$29.00
Billing & Payment	$1.28	$1.28
Subtotal Fixed		$30.28

Demand Charges

Charge	Calculation	Amount
Summer On-Peak Demand	5 kW × $25.36	$126.80
Summer Off-Peak Demand	3 kW × $7.48	$22.44
Subtotal Demand		$149.24

Energy Charges (Delivery Adjustments + Supply)

Charge	Calculation	Amount
Delivery Adjustments	800 kWh × ~$0.02 (varies)	~$16.00
MSC + Adjustments	800 kWh × ~$0.09 (varies)	~$72.00
CES (Delivery + Supply)	800 kWh × ~$0.006	~$4.80
Subtotal Energy		~$92.80

Riders & Taxes

Charge	Calculation	Amount
Various Riders	800 kWh × ~$0.004	~$3.20
GRT	~$273 × ~7%	~$19.11
Subtotal Riders		~$22.31

Total

~$294.63 for 800 kWh with 5 kW on-peak / 3 kW off-peak demand

Comparison to SC1

If this same 800 kWh were billed under SC1 (no demand charges):

Energy charges would be similar (~$92.80)
But no demand charges (~$149.24 saved)
Total would be ~$145

SC4 is more expensive for customers with high peak demand relative to consumption. It benefits customers with high, steady loads (like geothermal heat pumps that run consistently) rather than peaky loads.

Understanding the JSON

Demand-Based Charge Type

SC4 introduces the DEMAND_BASED charge type, distinct from CONSUMPTION_BASED:

{
  "rateName": "Demand Charge - Summer On-Peak",
  "chargeType": "DEMAND_BASED",
  "quantityKey": "billingDemand60min2252",
  "timeOfUse": {
    "touName": "Summer On-Peak",
    "touType": "ON_PEAK",
    "season": { "seasonName": "Summer" },
    "touPeriods": [
      { "fromDayOfWeek": 0, "fromHour": 12, "toDayOfWeek": 4, "toHour": 20 }
    ]
  },
  "rateBands": [{ "rateAmount": 25.36 }]
}

Field	Description
`chargeType: "DEMAND_BASED"`	Charge calculated from peak demand, not energy
`quantityKey`	Specifies which demand calculation to use
`rateAmount`	$/kW (dollars per kilowatt of demand)

Multiple TOU Periods

Notice how off-peak has two touPeriods:

"touPeriods": [
  { "fromDayOfWeek": 0, "fromHour": 20, "toDayOfWeek": 4, "toHour": 12 },
  { "fromDayOfWeek": 5, "fromHour": 0, "toDayOfWeek": 6, "toHour": 0 }
]

Period 1: Sun–Thu, 8pm to noon next day
Period 2: Fri–Sat, all day (day 5 and 6)

This is how the JSON represents "Friday and Saturday are entirely off-peak."

Tariff Properties

The properties array shows what inputs are needed to calculate bills. SC4 introduces demand properties not present in SC1 or SC3.

Property	Type	Period	Description	Default	Used For
`hasGeothermalHeatPumps`	BOOLEAN	—	Applicability flag	true	Rate eligibility
`consumption`	DECIMAL	—	Total energy usage (kWh)	—	Delivery adjustments
`demand`	DEMAND	ON_PEAK	60-min billing demand (kW)	—	On-peak demand charge
`demand`	DEMAND	OFF_PEAK	60-min billing demand (kW)	—	Off-peak demand charge
`systemSize`	DECIMAL	—	Solar system capacity (kW)	0	CBC rider
`territoryId`	CHOICE	—	Service zone (H, I, or J)	—	Zone-specific rates
`chargeClass`	CHOICE	—	Charge categories	DISTRIBUTION,SUPPLY,CONTRACTED	Filtering

Below we walk through the properties specific to SC4. For standard properties like territoryId and systemSize, see the SC1 documentation.

`hasGeothermalHeatPumps`

{
  "keyName": "hasGeothermalHeatPumps",
  "displayName": "Has Geothermal Heat Pumps",
  "dataType": "BOOLEAN",
  "propertyTypes": "APPLICABILITY",
  "propertyValue": "true"
}

An applicability flag indicating whether the customer has geothermal heat pumps. This may affect certain rate applicability rules within the tariff. Note that geothermal is not required to enroll in SC4—it's an opt-in rate available to all residential customers.

`demand[ON_PEAK]` and `demand[OFF_PEAK]`

{
  "keyName": "demand",
  "period": "ON_PEAK",
  "quantityKey": "billingDemand60min2252",
  "displayName": "60 Minute Billing Demand",
  "dataType": "DEMAND",
  "propertyTypes": "RATE_CRITERIA",
  "quantityUnit": "kW",
  "lookbackQuantity": 1,
  "lookbackPeriod": "BILLING_PERIOD",
  "lookbackIntervalQuantity": 60
}

The demand properties have additional fields that define how billing demand is calculated:

Field	Description
`quantityKey`	`billingDemand60min2252` — ConEd-specific calculation method
`dataType`	`DEMAND` — distinct from `DECIMAL` (energy)
`quantityUnit`	`kW` (kilowatts, not kilowatt-hours)
`lookbackQuantity`	1 — look back 1 billing period
`lookbackPeriod`	`BILLING_PERIOD` — within the current billing cycle
`lookbackIntervalQuantity`	60 — 60-minute integration interval

These properties require interval meter data to calculate billing demand. Standard monthly meters don't capture this information.

`consumption`

Unlike SC3, SC4 uses a single consumption property (not split by TOU). Energy charges (delivery adjustments, supply charges) are based on total kWh, not split by on-peak/off-peak.

How to Get Variable Rate Values

Same approach as SC1/SC3. See Variable Rates API Guide for detailed examples.

Key difference: When using the Calculate API, you must provide:

consumption — total kWh used
demand[ON_PEAK] — on-peak billing demand in kW
demand[OFF_PEAK] — off-peak billing demand in kW

Summary: What Makes SC4 Different

Demand charges: Core billing component based on peak power (kW), not just energy (kWh)
Opt-in for all: Available to any residential customer (geothermal not required)
Different TOU schedule: On-peak is only 12pm–8pm Sun–Thu; Fri–Sat are all off-peak
Higher fixed charge: $29/mo vs $20/mo for SC1/SC3
Interval metering required: Must have smart meter capturing 60-minute demand data
Benefits steady loads: Rewards consistent usage patterns over peaky consumption
Same energy charges: Delivery adjustments, supply charges, and riders work the same as SC1/SC3
