How NYSEG's default-service auction works
NYSEG runs a competitive solicitation for wholesale electricity in tranches that lay down 2-month strips of supply. Multiple suppliers bid against each other to provide a slice of the load; the lowest blended cost becomes the price NYSEG charges as the default. NYSEG itself does not profit on the kWh portion of the supply: state law forbids the utility from taking a margin on the electrons. The price you see on the supply line is the wholesale auction result plus a small unhedged risk allowance.
Step 1
Forecast load
NYSEG estimates how much energy default-service customers will consume in the upcoming 2-month tranche.
Step 2
Auction
Wholesale suppliers submit sealed bids. The lowest blended cost wins; NYSEG signs supply contracts for that tranche.
Step 3
Publish PTC
NYSEG converts the wholesale price to a retail per-kWh number (the Price-to-Compare) by adding losses and pass-throughs. This is the supply rate on your bill.
NYSEG default supply prices, 2024 to 2026
The supply line is the half of your NYSEG bill that moves with the wholesale market. Here is the broad shape over the last 24 months.
NYSEG residential supply rates have traded in a band of roughly 7 to 10 cents per kWh for the typical default-service customer through 2024 and into 2026, with the seasonal pattern of summer peaks and winter troughs reversed compared to bills (because winter wholesale gas pulls electric prices up while delivery charges on the bill are flat to seasonal). The all-in NYSEG residential price (supply plus delivery plus taxes) typically lands in the low-to-mid 20-cent range, sitting below the New York state residential average of 28.55 ¢/kWh reported by the EIA in March 2026.
The reason NYSEG supply is structurally cheaper than the Con Edison supply is geography: most of NYSEG sits in NYISO Zones C (Central), E (Mohawk Valley) and F (Capital), where wholesale prices clear below Zones I and J (downstate). That same geography, paradoxically, makes the delivery line on a NYSEG bill structurally more expensive (see the NYSEG hub page for the density-vs-delivery-cost analysis).

Benchmarking an ESCO offer against NYSEG default
Since New York's 1998 retail-choice law, you can buy your supply from a competitive ESCO instead of taking NYSEG's default. NYSEG still delivers the power, reads the meter and sends the bill; only the supply line on the bill changes. Here is how to read an ESCO offer in NYSEG context.
Fixed-rate offer
A fixed cents-per-kWh number for 6, 12 or 24 months. Compare it directly to the current NYSEG PTC. After the April 2026 PSC ESCO reforms, mass-market fixed offers must be priced at or below the utility default unless 30% of the energy is renewable.
Variable-rate offer
A rate that changes month to month at the ESCO's discretion. Historically the worst-performing format for residential customers. Treat with caution: even an introductory teaser rate can rise above the NYSEG PTC after the first cycle.
Green / renewable offer
Pays a premium for 30% or 100% renewable matching. The April 2026 reforms permit a premium over the NYSEG PTC for genuinely renewable products; verify the matching ratio in the ESCO contract before signing.
Bundle with appliances / smart thermostat
Increasingly common. The bundled hardware is rarely worth what the contract gives up; price the kWh portion in isolation and decide on the hardware separately.
Why shopping supply is a smaller lever in NYSEG territory than people expect
A typical NYSEG residential bill splits roughly half delivery, half supply. In Con Edison territory the split tilts more toward supply (the wires reach densely, so delivery is cheap; the load is in expensive Zone J, so supply is expensive). In NYSEG territory the split is the inverse: cheap supply, expensive delivery. The practical consequence is that an aggressive ESCO offer that saves you 1.5 ¢/kWh on the supply line saves a smaller percentage of the NYSEG bill than the same offer would on a Con Edison bill.
That does not make shopping pointless; it makes the maths sharper. On 700 kWh a month, 1.5 ¢/kWh in savings is $10.50 a month, $126 a year. Worth it if the contract has no exit fee and the rate is genuinely fixed. Less obviously worth it if a 12-month fixed-rate contract carries a $99 early-termination fee and a renewal-into-variable trigger.
Frequently asked questions about NYSEG supply prices
No. State law forbids it. NYSEG passes through the wholesale auction price to default-service customers with no margin. Its profit comes from the regulated delivery side.
The Price-to-Compare updates with each new auction tranche (typically every 2 months). The exact rate is published on the NYSEG monthly tariff filing.
Yes, especially with variable-rate offers. The April 2026 PSC reforms tightened the rules for mass-market customers, but variable-rate contracts and bundled offers can still end up above the NYSEG default. Always benchmark the all-in per-kWh price against the current PTC.
Look at the supply line of your most recent NYSEG bill, or check the PSC Power to Choose tool, which pulls live PTC and ESCO offers side by side.
NYSEG's default supply mix follows the New York grid mix and the state's Clean Energy Standard. For a contracted higher-renewable percentage you have to go through an ESCO that markets a green product.
Most NYSEG load sits in NYISO Zones C, E and F, where wholesale electricity clears below downstate Zones I and J. The same geography makes NYSEG's delivery line structurally expensive, which mostly offsets the savings.
