Reading a NYSEG Bill After Solar

The first NYSEG bill after a solar system is switched on is where expectations meet the tariff. It is almost never zero, and the confusion comes from one structural fact: the bill has two halves and solar only fully attacks one of them.

Supply and delivery

Supply is the electricity itself. If you buy from NYSEG, this is NYSEG’s supply charge; if you use an ESCO, it is that company’s charge on the same bill.

Delivery is the cost of moving it to your house over poles, wires and substations, and of maintaining them. It is NYSEG’s regardless of who supplies your electricity — and in a rural territory with long lines serving few customers, delivery is a substantial share of the bill.

Solar reduces the kilowatt-hours you buy, which cuts supply and the volumetric part of delivery. It does not cut the fixed part of delivery, and it does not touch the basic service charge.

Line by line

• Basic service charge. Fixed monthly, for being connected. Solar does not change it. This alone gives your bill a floor.
• Delivery, per kWh. Falls with what you draw from the grid.
• Supply, per kWh. Falls with what you draw from the grid.
• System benefit and similar public policy charges. Volumetric, so these fall too — which is exactly the shortfall the CBC exists to restore.
• Customer Benefit Contribution. New since your system was interconnected. Calculated on the DC size of the system at $1.19 per kW-month on NYSEG for 2026, so an 8 kW system adds $9.52 a month. It does not vary with production and is recalculated annually.
• Sales tax, applied as before.
• Credit balance. Where your banked exports appear.

How the credit balance behaves

From roughly March to September your exports exceed your imports and a dollar credit accrues on the account. Through the winter, when the array cannot cover the house, the balance is drawn down.

Read the bill across a year rather than month by month. Watch the credit balance rise from spring, peak in late summer, and fall through winter. If it reaches zero in January rather than March, the system is undersized — worth knowing before a second winter, and in NYSEG territory it is a common outcome because electric hot water and supplementary electric heat push winter consumption above what a template assumed.

Why the bill is not zero

1. The basic service charge and the fixed portion of delivery do not move.
2. The Customer Benefit Contribution is a new charge that did not exist before.
3. Unless the system covers 100% of annual consumption — and many are deliberately sized below that — you are still buying some electricity.

A small bill is the correct outcome. If you were told it would be zero, compare that against these three lines.

The first bill is usually strange

The billing cycle rarely aligns with your permission-to-operate date, so the first statement often straddles a pre-solar and a post-solar period. The second full cycle is the first honest one; the first full year is the only one that really answers the question.

What to check on the first full bill

• That the CBC line matches your system’s DC size × $1.19. If not, the size on file may be wrong.
• That exports are actually being recorded — a meter never properly exchanged shows consumption only.
• That the account is on the correct rate and the net-metering arrangement is in place.

If exports are missing, raise it immediately. Retroactive correction is possible but much easier when the gap is one cycle rather than six.

Frequently Asked Questions

Why is my NYSEG bill not zero after solar?

The basic service charge and the fixed portion of delivery do not change with consumption, the Customer Benefit Contribution is a new charge based on system size, and most systems are not sized to cover 100% of annual usage.

Why is delivery such a large share of a NYSEG bill?

NYSEG serves a largely rural territory with long lines serving relatively few customers, so the cost of moving electricity is a substantial part of the bill — and solar only reduces the volumetric portion of it.

What does it mean if my credit balance runs out in January?

That the system is undersized. It is a common outcome in NYSEG territory because electric hot water and supplementary electric heat push winter consumption above what a template assumed. Size against twelve months of actual usage.

What is the new charge on my bill since installing solar?

The Customer Benefit Contribution, at $1.19 per kW-month of DC system size on NYSEG for 2026 — about $9.52 a month on an 8 kW system. It does not vary with production and is recalculated annually.
