Rate Definition
EV Phase-In Rate Overview
This rate is available for commercial customers who have or plan to install electric vehicle charging stations at their business. The EV Phase-In Rate considers factors such as how often the chargers are used, your energy use, energy demand, and more, to provide a rate option that fits best with your EV charging station(s).
Is this rate right for me?
You may qualify for this rate if this best represents your business:
- Public EV Charging: Have a charging station(s) that the general public can access
- Workplace EV Charging: Offer workplace charging for your employees
- Multi-Family EV Charging: Offer EV charging to residents in a multi-family community
- Fleet Electrification: Manage a fleet of electric vehicles
While this rate is not available to residential customers, our Time-of-Day rates, such as Rate 195, offer discounted rates when you charge your EV during the off-peak periods.
The rate tier structure for the EV Phase-in rate consists of four load factor-based tiers
A customer’s load factor determines their appropriate tier. Within each tier, there is a customer charge, an energy charge, and a demand charge component (except for Tier 1) with varying ratios. The assigned tier determines how a customer’s electric bill is calculated. Your load factor is based on the amount of energy consumed over a time period, compared to the nameplate of the equipment. As charger use and, as a result, your load factor increases, so does your tier. As your tier increases, the rate phases-in a larger percentage of demand charges.
This rate has three time periods
Peak, Off-Peak, and Super Off-Peak. Additionally, there is a seasonal component where rates are set higher in the summer and lower in the winter period.
Your load factor indicates the frequency of a charging station’s use compared to its peak demand throughout the year.
More frequent use leads to a higher load factor. As shown in the formula displayed, annual load factor computation is the ratio of annual energy consumption (through AMI data) to the product of the simultaneous charging capacity (when available, otherwise nameplate capacity) and 8,760 hours (or 8,784 hours during a leap year).
Calculating your load factor
We calculate your load factor every January 1 and July 1. Using the load factor formula, PSEG Long Island will automatically calculate your load factor based on the past twelve months of meter data. New customers will be placed on the first tier until at least six months of meter data is available. Once we calculate your load factor, we will place your account on the appropriate tier. You would remain on the same tier if your load factor is within the same tier after calculation.
