Why is the New York electricity price called an estimate?

Because above 250 kilowatts, National Grid upstate customers buy energy at NYISO hourly day-ahead prices — there is no filed supply rate to model. The modeled figure is the trailing twelve-month average of Capital Zone monthly prices plus the monthly-restated supply adders, refreshed quarterly and disclosed with every result. Monthly averages in the current window ranged from about 4 to 19 cents per kilowatt-hour; a site with a competitive supply contract can enter its contracted rate in the wizard instead.

Does New York charge a demand charge on EV charging?

On the standard large-service schedule, yes: about $15.62 per kilowatt of delivery demand plus per-kilowatt riders and NYISO capacity charges, folding to about $26.78 all-in with sales tax. National Grid's EV Phase-In Rate assigns reduced demand charges by annual load factor — down to $0 in its lowest tier — but recovers the difference through time-of-use energy adders in a structure the model discloses rather than expresses.

Does New York tax charging equipment as business property?

No. New York State does not tax tangible business personal property at all — the recurring equipment-tax line that weighs on California, Rhode Island, or Georgia scenarios is absent. Sales tax applies to the hardware purchase at the site's combined county rate, about 8% in the Capital District, and installation labor generally falls outside the taxable base when the work qualifies as a capital improvement.

Tesla Supercharger ROI in New York

New York coverage runs through upstate National Grid territory — the Capital District, Syracuse, Utica, and downtown Buffalo — on Schedule SC-3, the mandatory large-service class. Above 250 kilowatts the supply side has no filed price at all: the site buys energy at NYISO day-ahead hourly wholesale prices. The model prices that supply at the trailing twelve-month average of Capital Zone monthly prices — about 7.1 cents per kilowatt-hour of raw energy in the current window, against filed months that ranged from under 4 cents to almost 19 cents in January — and states plainly, wherever results appear, that the figure is an average of a floating market rather than a filed rate. Delivery is conventional: a verified 50% trailing ratchet that stays inert at charging-site load shapes, and an all-in demand figure of about $26.78 per kilowatt-month once capacity charges and sales tax fold in.

What makes New York economics distinct

The supply price is the wholesale market itself

SC-3 customers above 250 kilowatts for six consecutive months take mandatory hourly pricing — every kilowatt-hour bills at that hour's NYISO day-ahead price. The modeled figure is the trailing twelve-month average of Capital Zone monthly prices, refreshed quarterly, plus the utility's monthly-restated supply adders and capacity charges. Monthly averages in the current window ran from about $37 to $190 per megawatt-hour — January alone averaged five times the September floor — and the wizard's energy-rate fields accept a contracted supply price in place of the average, the arrangement most operators at this scale negotiate.

Where coverage runs, and where it deliberately stops

The modeled row is National Grid upstate only. Consolidated Edison and Long Island bill demand through multi-window time-of-use stacks the model does not fold; NYSEG and Rochester Gas & Electric sit on temporary rates with four rate cases pending; and every New York utility's EV-specific offer assigns its rates by annual load factor — a tier design the model discloses rather than approximates. An address in those territories resolves to a named utility with a notice instead of a wrong number. One Buffalo nuance: downtown is National Grid, while the Walden Avenue retail corridor east of the city is NYSEG.

No business personal property tax — a genuine structural zero

New York does not tax tangible business personal property; the statute excludes it from ad valorem taxation outright. The declining five-figure annual line that California, Georgia, or Rhode Island scenarios carry simply does not exist, worth roughly $15,000 to $56,000 a year against the heavier states at model hardware values. The open caveat is fixtures: permanently affixed site improvements can raise the parcel's real-property assessment, a site-specific question with no EV-charging guidance on record.

An EV rate exists — and the model tells you it isn't modeled

National Grid files an EV Phase-In Rate for exactly this customer class: four demand tiers assigned by annual load factor, with a $0 demand charge in the lowest tier and the forgiven revenue recovered through time-of-use energy adders, re-evaluated twice a year. The model does not express that structure and says so with every New York result. A site that enrolled and stayed in the low tiers would see a materially lower demand line than the standard-schedule figure modeled here — the modeled cost is the conservative side of a real enrollment decision.

Utilities and tariffs modeled in New York

Utility & tariff	Energy	Demand
National Grid NY SC-3No fixed supply price is filed for this customer class — the utility bills supply at market prices that change monthly. The modeled energy figure folds the trailing twelve-month average of the filed monthly prices, an estimate rather than a filed rate; a site's actual supply cost follows the market or a competitive supply contract, and the wizard's energy-rate fields accept a contracted rate in place of the average. New York places National Grid upstate sites of this size on mandatory hourly pricing: SC-3 supply bills at NYISO day-ahead zonal prices, and the modeled average spans July 2025 through June 2026 in the Capital Zone, a window whose monthly averages ranged from about 4 to 19 cents per kilowatt-hour.

New York tax profile

Sales tax on hardware: 8%
Business personal property tax: none
Clean-fuels credit: no program
Per-kWh charging excise: none

New York tax defaults applied: no clean-fuels credit program reaches EV charging in New York today (the LCFS revenue line is $0; a clean fuel standard bill sits in Senate Finance), and LLC costs use the $500 annual filing-fee tier plus the biennial statement share — New York levies no franchise tax on LLCs. Sales tax on hardware is 8% at the canonical Albany County site (New York City runs 8.875%, and the county rate is editable), with installation labor outside the base when the install qualifies as a capital improvement under Form ST-124. Business personal property is untaxed statewide, though permanently affixed site improvements can raise the parcel's real-property assessment. New York applies sales tax to the site's commercial electric bill — that fold is already inside the modeled utility rates — and also to electricity sold to drivers, which this model treats as collected on top of the posted price and remitted, leaving revenue figures unchanged. No per-kWh charging tax exists in New York. The utility EV Make-Ready program closed to new applications in April 2026, with a possible fast-charging-only reopening under Public Service Commission review.

New York programs and incentives

Utility EV Make-Ready (Case 18-E-0138)

The $1.24 billion statewide make-ready program stopped accepting new applications in April 2026; pipeline applications continue, and the commission's order permits a DCFC-only reopening conditioned on utilization reporting. A reopened award would enter the model through the grant inputs; the default models $0.

State alternative-fuels infrastructure credit (§187-b)

Lesser of $5,000 or 50% of cost per unit of charging property, extended through tax year 2028 — small at Supercharger scale, and state income tax sits outside the model, so the credit is noted rather than modeled.

New York charging market

Covered New York territory holds nine verified Supercharger sites: six across the Capital District — three in Albany plus Latham, Guilderland, and Clifton Park — and three around Syracuse, with National Grid also serving Utica and downtown Buffalo along the Thruway spine. The unmodeled territories are the bigger prize and the harder problem: Consolidated Edison's multi-window demand stacks downstate, Long Island's tariff, and the Avangrid utilities mid-rate-case all resolve to named territories with a notice. A clean fuel standard — which would add a revenue line to every New York scenario — passed the state Senate committee stage in May 2026 and sits in Senate Finance.
