How to Choose the Best Electricity Rates for Your Commercial Business (Compared)
Commercial electricity costs are shaped by more than the advertised cents-per-kilowatt-hour rate. Capacity charges, PLC tags, transmission costs, demand spikes, contract adders, and renewal terms can materially change the total cost of service.
For commercial businesses operating in deregulated states such as New Jersey, comparing electricity rates requires an analysis of both the supply offer and the facility’s usage profile. This applies across restaurants, hotels, commercial real estate, retail, healthcare, warehouses, manufacturing, and other multi-site or energy-intensive operations. The PJM capacity price for the 2026/2027 delivery year is $329.17 per MW-day, equivalent to approximately $120,147 per MW-year or $120.15 per kW-year.
That capacity price is a major factor in evaluating electricity rates for commercial facilities in 2026.
1. Understand Why PJM Capacity Prices Are Increasing Commercial Energy Costs
PJM Interconnection operates the regional transmission system and wholesale electricity market serving New Jersey and 12 other states plus Washington, D.C.
On July 22, 2025, PJM announced the results of its Base Residual Auction for the June 1, 2026–May 31, 2027 delivery year. The auction cleared at:
$329.17/MW-day
Approximately $120,147/MW-year
Approximately $120.15/kW-year
Approximately 22% higher than the 2025/2026 auction price of $269.92/MW-day
Capacity is a payment for maintaining sufficient generation and demand-response resources to serve peak system demand. Suppliers generally recover this cost through a customer’s electricity supply rate or through a separate capacity line item.
For a New Jersey commercial facility with a 50 kW PLC tag, the capacity component alone could be estimated as:
50 kW × $120.15 = $6,007.50 per year
Approximately $500.63 per month
This is a planning estimate before supplier adders, transmission charges, utility delivery charges, taxes, and other applicable components.
The capacity rate does not represent the entire electricity bill. It represents one wholesale cost component that can materially affect the final price.
2. Review the Facility’s PLC and Capacity Tag
A Peak Load Contribution, commonly called a PLC or capacity tag, measures a customer’s allocated share of PJM system peak demand.
In New Jersey, the PLC calculation generally uses the customer’s demand during PJM’s five highest summer system peak hours, known as the 5CP period. These peak hours occur between June 1 and September 30 and are typically associated with hot weekday conditions.
The calculation generally involves:
Hourly customer demand during the five PJM coincident peaks
Utility-specific loss factors
Zonal reconciliation adjustments
The resulting PLC in kilowatts
Application of that PLC to the next June–May delivery year
A commercial facility may have moderate monthly energy consumption but still carry a high PLC if HVAC systems, lighting, production equipment, server rooms, refrigeration, elevators, ventilation, or common-area loads operate simultaneously during the system peaks.
Commercial operators should request the following information from the utility or supplier:
Current PLC or capacity tag in kW
Applicable delivery-year capacity rate
Whether capacity is included in the quoted supply rate
Whether capacity is billed at actual cost or through a fixed adder
The methodology used to calculate or pass through capacity charges
Reducing demand during future PJM peak hours can lower a future PLC, but it does not usually change an already-established tag immediately. The timing of peak management is therefore important.

3. Compare Fixed, Index, and Hybrid Supply Offers
The best electricity rates for commercial businesses depend on the facility’s operating pattern, risk tolerance, contract timing, and ability to manage usage.
Fixed-rate electricity contracts
A fixed-rate contract establishes a set supply price per kWh for a defined term.
Advantages include:
More predictable budgeting
Protection from short-term wholesale market spikes
Easier forecasting for occupancy, payroll, production, and operating margins
Reduced exposure during extreme weather events
Potential limitations include:
The business may pay more if wholesale prices decline
Capacity or transmission costs may remain outside the fixed price
Early termination fees may apply
Renewal terms may create a new variable-rate exposure
A fixed rate is not automatically an all-in rate. The contract must specify whether the fixed price includes capacity, transmission, ancillary services, renewable compliance costs, and other pass-through charges.
Index or variable-rate contracts
An index contract typically uses a formula such as:
> PJM market index + supplier adder + applicable charges
The index may reference a day-ahead market, real-time market, monthly hub, or another published wholesale benchmark.
Advantages include:
Potential access to lower prices when wholesale markets decline
Greater pricing transparency when the formula is clearly stated
Flexibility for sophisticated energy users
Possible benefits for businesses that actively manage consumption
Potential limitations include:
Higher bills during heat waves, cold snaps, or supply disruptions
Greater exposure to capacity and transmission volatility
More complex budgeting
Risk from unclear index definitions or uncapped adders
Index pricing may suit a multi-location business with strong data monitoring and flexible load. It may be less appropriate for a single facility that requires consistent monthly budgeting.
Hybrid contracts
Hybrid structures combine fixed and market-based pricing. For example:
A fixed price applies to baseline usage
Excess usage follows an index
The first portion of the contract term is fixed
Capacity is fixed while energy floats
A percentage of annual usage is hedged in advance
Hybrid pricing can balance budget stability and market participation, but the formula must be modeled against actual facility usage before signing.
4. Read the Commercial Energy Contract Line by Line
A supply proposal should be compared on total expected cost rather than the headline supply rate.
The following contract sections require review:
Price definition
Confirm:
Price per kWh or pricing formula
Contract start and end dates
Market index used, if applicable
Supplier adder
Minimum usage or volume requirements
Whether the rate applies to all meters and locations
Capacity language
Look for terms such as:
Capacity
PLC
Peak Load Contribution
Installed capacity
Capacity obligation
PJM peak
Pass-through
Actual cost
Capacity adder
The contract should clearly state whether the supplier absorbs capacity changes or passes them through to the business.
Other pass-through charges
Verify how the offer handles:
Transmission
Ancillary services
Renewable energy certificates
Public policy charges
Regional uplift charges
Utility distribution charges
Taxes and assessments
A low energy rate can be offset by uncapped or undefined pass-through charges.
Renewal and termination
Review:
Automatic renewal provisions
Renewal notice deadlines
Default rate after expiration
Early termination fees
Assignment rights if the business is sold
Treatment of closed, relocated, expanded, or newly added locations
A commercial customer should not allow a contract to roll automatically into a month-to-month variable product without a documented review.

5. Reduce Demand Spikes During Facility Peak Hours
Commercial facilities frequently create demand spikes when multiple high-load systems start simultaneously.
Common contributors include:
HVAC compressors and aggressive cooling setpoints
Lighting schedules across offices, retail floors, and common areas
Server rooms, IT closets, and process-cooling equipment
Production equipment and motor-driven machinery
Refrigeration and cold-storage systems
Elevators, ventilation, and domestic hot water systems
Multi-tenant common-area loads
Battery charging, material handling, or warehouse equipment
Electric process loads in healthcare or manufacturing environments
A single short demand spike can increase the monthly demand charge for applicable utility tariffs. Repeated high usage during PJM’s summer coincident peaks can also affect a future PLC.
Operational controls can include:
Staggering startup of major equipment and motor loads
Scheduling noncritical production or process loads outside likely system peak windows
Pre-cooling the facility before the hottest afternoon period
Adjusting HVAC setpoints without compromising occupant comfort, product integrity, or operational requirements
Reviewing lighting schedules in offices, sales floors, warehouses, and common areas
Managing server-room cooling and ventilation more precisely
Using energy management controls for HVAC, lighting, and process equipment
Evaluating demand-response eligibility for larger facilities
Peak management should not compromise health regulations, employee safety, tenant comfort, product quality, or core operations. The objective is to reduce unnecessary simultaneous load while maintaining normal operations.
6. Use Energy Data Before Choosing a Rate
A commercial business should use at least 12 months of billing data, and preferably 24 months, when evaluating electricity rates.
The analysis should identify:
Monthly kWh consumption
Monthly peak kW demand
Seasonal HVAC changes
Operating hours
Location-specific usage differences
Current PLC and capacity charges
Contract expiration dates
Billing anomalies
Usage changes from renovations, tenant turnover, production changes, or new equipment
Energy Tracker Pro, United Energy Consultants’ proprietary utility management software, consolidates usage and expenditure data so commercial operators can monitor multiple locations, identify anomalies, and evaluate procurement timing.
Data supports better decisions in three areas:
Rate selection: Fixed, index, or hybrid pricing can be modeled against actual usage.
Peak management: High-demand intervals can be linked to equipment schedules.
Supplier negotiations: Multiple offers can be compared using consistent load assumptions.
Without usage data, a business is comparing marketing rates rather than actual projected costs.

Final Comparison: Which Electricity Rate Is Best for a Commercial Business?
The most competitive electricity rates for commercial businesses are determined by total delivered cost, not the lowest advertised kWh price. PJM’s $329.17/MW-day capacity price, the facility’s PLC tag, demand profile, and contract language all affect the result.
Business owners and facility managers can contact United Energy Consultants for a no-cost review of current electricity rates, capacity charges, and contract options. A recent utility bill is the starting point for identifying whether a fixed, index, or hybrid strategy provides the strongest cost and budget position.
