Tiered Rate Plans: NJ Electricity Explained

A homeowner in Montclair opens her August electric bill and notices it is nearly forty dollars higher than July, even though her household did not add any new appliances. She used more electricity running the air conditioner through a heat wave, and her utility charges a higher price per kilowatt-hour once usage crosses a certain threshold. That structure has a name: a tiered, or block, rate plan.

Block rate plans are among the most common electricity pricing structures in regulated utility markets. Understanding how they work, and how they interact with New Jersey's competitive supply market, is one of the most practical things a ratepayer can do before the next hot summer or cold winter.

A tiered rate plan divides your monthly electricity consumption into bands, sometimes called tiers or blocks. The first block covers usage up to a set threshold (a common example is the first 500 kWh). Kilowatt-hours in that first block are priced at one rate. Once you cross the threshold, every additional kWh is priced at a higher rate.

Some utilities use two tiers; others use three or more. The logic behind the structure is to keep baseline usage affordable while making heavy consumption progressively more expensive, which can also encourage conservation. For households that run electric heat, have home offices, or charge electric vehicles, the higher tiers can represent a substantial share of the monthly bill.

Graduated rate is another term you may see for this structure. Whether a utility calls it tiered, graduated, or block pricing, the mechanics are the same: crossing a consumption threshold changes the per-kWh price going forward for that billing period.

New Jersey's four investor-owned electric utilities, PSE&G, JCP&L, Atlantic City Electric, and Rockland Electric, are regulated by the NJ Board of Public Utilities (NJBPU). Each utility collects two broad categories of charges on your bill: delivery charges (the wires, poles, and metering infrastructure) and supply charges (the actual electricity generation).

The supply portion is what competitive suppliers and the default utility supply program both address. New Jersey's default supply product is called Basic Generation Service (BGS). The NJBPU oversees a competitive procurement process to set BGS rates, which are periodically adjusted. If you have never chosen a third-party supplier, you are on BGS.

Whether a utility layers a tiered structure onto its delivery charges, its supply charges, or both depends on its specific tariff. Tariffs are public documents filed with the NJBPU; you can look up your utility's current tariff on the NJBPU website or request a copy from your utility directly. For live rate comparisons, ElectricRates.org's New Jersey page tracks current BGS and supplier offers side by side.

The case for switching to a competitive supplier depends almost entirely on which utility serves your home. As of June 2026, the picture across New Jersey's four utilities is uneven.

PSE&G customers are in the strongest position to save. The BGS supply rate is approximately 19.9 cents per kWh. The lowest competitive supplier offer in the PSE&G territory is around 17.6 cents per kWh, which represents roughly an 11 percent reduction on the supply portion of the bill. For a household using 1,000 kWh per month, that difference adds up quickly.

Atlantic City Electric customers also have options. The BGS rate sits near 18.2 cents per kWh, and the lowest available supplier rate is approximately 16.7 cents, about an 8 percent savings on supply charges.

JCP&L customers should pause before switching. The BGS rate in JCP&L territory is approximately 14.6 cents per kWh, and the lowest competitive supplier offer is around 16.0 cents. Switching would cost more, not less. Staying on BGS is the cheaper supply option in this territory right now.

Rockland Electric customers face a similarly thin market. The BGS rate is approximately 18.8 cents per kWh, and very few competitive suppliers serve this territory. The lowest offer found is around 18.9 cents, which provides no meaningful savings. BGS is effectively the default best option here as well.

These figures apply to supply charges only. Delivery charges are set by the utility and regulated by the NJBPU; no competitive supplier can change them.

When a competitive supplier quotes you a flat per-kWh rate, that rate applies uniformly across your entire consumption. Your utility's BGS rate may be tiered, meaning the effective average BGS supply cost depends on how much you use.

Here is why that matters: if a utility's BGS tier one rate is very low but the tier two rate is high, a heavy user may pay a high blended average BGS supply cost. A flat supplier rate that looks slightly higher than tier one might still be cheaper than the blended average a heavy user actually pays on BGS.

Conversely, a light user who stays entirely within a low first tier on BGS might find that no competitive supplier can beat that tier one rate. This is part of why the comparison is not always straightforward. Reviewing your actual monthly usage, checking which tier you typically fall into, and comparing that to supplier offers gives a much clearer picture than looking at any single rate in isolation.

For households where energy costs are a significant burden, New Jersey offers assistance programs separate from the competitive supplier market. The Universal Service Fund (USF) program provides a credit on electric and gas bills for eligible low-income customers. LIHEAP (Low Income Home Energy Assistance Program) offers federally funded assistance to help with energy bills during high-usage seasons.

Eligibility and benefit amounts for both programs depend on household income and size. The NJBPU and the New Jersey Department of Community Affairs administer these programs. For current eligibility criteria and application details, visit the NJBPU's customer assistance page or contact your utility directly. Do not rely on any third party claiming to enroll you in these programs as part of a supplier switch; assistance enrollment and supplier choice are separate processes.

New Jersey electric bills list supply and delivery charges separately, which is one of the more useful features of the state's retail market structure. The supply section will show either a BGS rate line or, if you have already enrolled with a third-party supplier, your supplier's rate. The delivery section will show the utility's distribution, transmission, and any other infrastructure charges.

If you want to evaluate whether switching makes sense, the number to focus on is the supply rate and the total supply charge for the billing period. Divide your total supply charge by the kilowatt-hours used that month and you have your effective supply rate. Compare that to supplier offers available in your territory.

For a current list of licensed suppliers in your utility's territory, the NJBPU maintains a supplier directory. ElectricRates.org's New Jersey rate comparison tool also pulls current offers together in one place so you can see what is available without contacting each supplier individually.

The process does not need to be complicated. First, find your utility territory (PSE&G, JCP&L, Atlantic City Electric, or Rockland Electric). Second, look at your last several bills to find your average monthly kWh usage and your current supply rate. Third, compare that rate to current competitive supplier offers.

If you are a PSE&G or Atlantic City Electric customer, as of June 2026, there are supplier offers that undercut the BGS rate by a meaningful margin. If you are a JCP&L or Rockland Electric customer, the competitive market currently offers no advantage over BGS, so staying put saves the effort and avoids any risk of enrolling in a contract with unfavorable terms.

When evaluating any supplier offer, confirm whether the rate is fixed or variable, how long the contract term lasts, whether there is an early termination fee, and what happens at contract end. A supplier contract that starts competitive but reverts to a high variable rate after the introductory period can cost more over time than simply staying on BGS. The NJBPU requires licensed suppliers to disclose these terms clearly before you enroll.

Tiered and block rate electricity plans add a layer of complexity to what most people assume is a simple monthly bill. In New Jersey, where supply and delivery charges are separated and a competitive supplier market operates alongside BGS default supply, understanding how those blocks interact with your usage pattern can reveal real savings, or confirm that your utility's default rate is already the better deal.

The opportunity is not uniform. PSE&G and Atlantic City Electric customers currently have concrete savings available from competitive suppliers. JCP&L and Rockland Electric customers are better served staying on BGS until the market shifts. Rates change, and what is true in June 2026 may look different by the time you read this.
