Merchant Function Charge: The Line Item Nobody Explains

It pays for the utility acting as your energy supplier rather than as your wires company, which is why it sits on the half of the bill a competitive supplier can replace.

What the Merchant Function Charge Pays For

New York separated the electricity business into two halves. Your utility
delivers the power over its wires, and it is regulated for that. The energy
itself can come either from the utility, which buys it on your behalf, or from
a competitive supplier you choose.

When the utility is buying the energy for you, it is doing a job on top of
delivering it: procuring the supply, carrying the credit risk of customers who
do not pay, running collections, and administering the whole arrangement. The
merchant function charge is the line that recovers the cost of that job. It is
attached to the supply side of the bill rather than the delivery side, and its
existence is the point — it makes the cost of the utility acting as a supplier
visible instead of buried.

Where it sits on the bill

Because it sits in the supply half, it is one of the items a competitive
supply offer is implicitly competing against — and it is also one of the items
people forget when comparing a supplier’s quoted price with what they are
paying now.

Why it makes comparison shopping harder than it looks

A supply offer is normally quoted as a single price per unit of energy. Your
current bill is not a single price: it is a supply price plus a set of
supply-side adjustments and charges of which this is one. Comparing the
supplier’s number against only the utility’s energy price leaves out part of
what you are currently paying, and comparing it against the whole supply
section can overstate the other way.

The reliable method is arithmetic on your own bills rather than on a
brochure. Total the supply section of several recent bills, divide by the
energy those bills covered, and compare that against the offer on a like basis
including anything the supplier adds. That method, and the clauses that decide
whether the quoted price survives past the first months, are set out in
making two supply prices line up and in
the clauses that decide an ESCO price.

Why it will not be the reason your bill is high

It is worth being blunt about scale. This is a small charge relative to the
energy and delivery components, and finding it on a bill is usually a symptom
of reading the bill carefully for the first time rather than of discovering an
overcharge.

If a bill is higher than expected, the causes are almost always elsewhere:
more energy used than assumed, a seasonal shape that was misread, a rate
change, or in a solar house the interaction between production and the fixed
charges that do not go away. Those are covered in
why a year of bills looks the way it does and in
why an electric bill stays high after solar.

What the charge is genuinely useful for is understanding the structure. Once
you can see that a bill has a delivery half and a supply half, and that the
supply half contains administration as well as energy, the rest of the document
stops being opaque.

How the amount is set

It is a tariff item, which means it is filed with and approved by the state
regulator rather than set by the utility at will, and it differs between
utilities and between rate classes. It also changes over time as the underlying
costs change and as rate cases are decided.

That last point is why no article should quote you a figure. The number that
applies to you is in your utility’s current tariff for your service class, and
on your own bill. Read it there rather than from a page that may have been
written under a previous rate case — the same caution that applies to every
rate on the bill.

What happens to it if you switch supplier

Switching to a competitive supplier moves the procurement and much of the
administration to that supplier, so the utility’s charge for performing that
function changes accordingly. What it does not do is remove costs — the
supplier has the same functions to perform and prices them into its own offer,
where they are usually less visible than a separately named line.

So the honest framing is that switching relocates this cost rather than
eliminating it, and whether you come out ahead depends entirely on the total
supply price you end up paying. That is the comparison to do, and it is the one
a supplier’s marketing is least likely to make easy.

If a switch goes wrong — a price that jumped after an introductory period,
an enrolment you did not agree to — the route to resolving it starts with the
utility and escalates to the state regulator, which is described in
the complaint process New York uses.

Reading your own bill for it

It appears in the supply section, named in full or abbreviated. If you
cannot find it, two things are worth checking before concluding it is absent:
whether you are on competitive supply already, and whether your utility groups
supply-side charges under a summary line with the detail on a later page.

The layout differs by utility, and each has its own conventions about what
is itemised and what is grouped — the walkthrough for one of them is in
reading a NYSEG bill, and the same approach transfers.

One thing worth doing while you have the bill open: look at what fraction of
the total is delivery rather than supply. For a household adding a heat pump or
an EV charger, that ratio is what decides how much of the new consumption is
actually influenceable by shopping for supply, and how much of it responds
instead to when you use the energy — which is the argument in
running a heat pump on a time-of-use rate.

Frequently Asked Questions

What is the merchant function charge?

It is a line on the supply side of a New York electric bill that recovers the cost of the utility acting as your energy supplier: procuring the supply, carrying the credit risk of customers who do not pay, running collections, and administering the arrangement. It exists so that the cost of the utility performing that function is visible rather than buried in the energy price.

Is it a delivery charge or a supply charge?

Supply. Delivery covers the wires, poles, meters and the regulated cost of running the network, and it applies whoever supplies your energy. The merchant function charge belongs to the half of the bill that a competitive supplier can replace, which is why it matters when comparing offers.

Does it go away if I switch to an ESCO?

Switching moves the procurement and much of the administration to the supplier, so the utility’s charge for performing that function changes accordingly. It does not remove the underlying costs: the supplier performs the same functions and prices them into its own offer, usually less visibly than a separately named line. The comparison that matters is total supply price.

How much is it?

It is a tariff item, filed with and approved by the state regulator, and it differs between utilities and rate classes and changes over time as rate cases are decided. That is why no article should quote a figure at you. The number that applies is in your utility’s current tariff for your service class, and on your own bill.

Is this why my bill is so high?

Almost certainly not. It is small relative to the energy and delivery components, and finding it is usually a sign of reading a bill carefully for the first time rather than of discovering an overcharge. Higher bills usually come from more energy used than assumed, a misread seasonal shape, a rate change, or in a solar house the fixed charges that do not go away.

Why can’t I find it on my bill?

Check two things before concluding it is absent. Whether you are already on competitive supply, which changes what the utility itemises, and whether your utility groups supply-side charges under a summary line with the detail on a later page. Bill layouts differ by utility and each has its own conventions about what is itemised and what is grouped.

How should I use it when comparing supply offers?

Do the arithmetic on your own bills rather than on a brochure. Total the whole supply section across several recent bills, divide by the energy those bills covered, and compare that figure against the offer on a like basis including anything the supplier adds. Comparing an offer against only the utility’s energy price omits part of what you currently pay.

Who decides what it is?

It is set through the regulated tariff process rather than by the utility unilaterally, so it is filed with and approved by the state regulator and revisited in rate cases. If you believe something on the supply side of your bill is wrong, the route starts with the utility and escalates to the state regulator rather than beginning there.
