Long Island Power Authority (LIPA) SC 2-EVC 285 — EV fast-charging electricity cost

LIPA SC 2-EVC 285 (Tier 1) is the filed rate schedule ForgeAsset models for DC fast-charging sites in Long Island Power Authority territory in New York. Energy prices at 21.2¢/kWh–27.5¢/kWh by time of day; the demand side bills none. For one reference Supercharger site held constant across the whole library, that works out to 27.6¢/kWh per dispensed kWh — rank 32 of 96 filed tariffs (1 = least expensive).

Modeled rates

The Long Island Power Authority's opt-in commercial EV charging rate, the filed alternative to a large-general-service schedule that carries a $30-per-kilowatt summer demand charge. The rate assigns one of four tiers from the site's annual load factor; a fast-charging site at 5-to-10% load factor sits in Tier 1, where the demand charge is zero in both rate periods and every new participant starts, so this row models Tier 1 and states the rest: the higher tiers trade demand charges of $4.47 to $13.41 per kilowatt for progressively lower energy rates, a shape this model does not express. Winter carries no peak period at all as filed, so kilowatt-hours in the weekday late-afternoon window bill at the peak rate for the four summer months and at the off-peak rate for the other eight; the peak figure here is that four-eight blend across the year. Because there is no demand charge, supply dominates the bill — the Power Supply Charge is a monthly-resetting fuel clause that ranged from 11.6 to 16.6 cents per kilowatt-hour over the twelve months from September 2025 through August 2026, and the energy figures fold that trailing twelve-month average rather than any single month, together with the efficiency, merchant-function, decoupling, delivery-adjustment, state-assessment, Shoreham property tax, and payment-in-lieu-of-taxes riders, and New York's sales tax at the Suffolk County rate of 8.75%. Suffolk County's 2.2248% Shoreham surcharge is included; a Nassau County or Rockaway Peninsula site pays no Shoreham surcharge and a Nassau site's sales-tax rate is 8.625%. The payment-in-lieu-of-taxes percentage used is the one filed for cities and incorporated villages; most of Long Island's land area is unincorporated, where the filed percentage is about a point lower, and the authority's statement of those percentages is stamped effective 2014 with no newer statement published. One item is genuinely unresolved: the underlying Rate 285 schedule carries annual minimum demand charges, and this EV rate neither restates nor waives them — the filed leaves, the authority's board memo, the state department letters, and the utility's brochure are all silent, and no minimum is modeled here in either direction; confirming the treatment in writing with PSEG Long Island is what settles it. Eligibility is by application with a charging ratio of at least 50%, an interval meter, and an annual load factor under 25%, and is closed to participants in the authority's fast-charging incentive program. For a separately metered site the load factor divides by the lesser of total nameplate charging capacity and the maximum simultaneous charging capacity, so at a 500-kilowatt service Tier 1's ceiling is 438,000 kilowatt-hours a year. The daily service charge is not modeled. New York tax defaults apply on address resolve; the hardware sales-tax anchor in that profile is the Albany County rate and a Long Island county rate differs, editable per site.

What the reference site pays here

Reference site: 8 Tesla V4 stalls at 235 kWh/stall/day (57,183 kWh dispensed per month), a 150kW per-stall demand assumption, the model's default time-of-use mix, and a 12% loss gross-up — identical to the full utility ranking, where this tariff sits at position 32 of 96.

The rest of the New York picture

The tariff is one layer. State taxes, incentives, clean-fuels programs, and the charging market shape the remainder — Tesla Supercharger ROI in New York covers them, and the US Supercharger Economics Map shows every US Supercharger over utility territories colored by this same effective-cost derivation.

Long Island Power Authority (LIPA) SC 2-EVC 285 — questions

What does Long Island Power Authority (LIPA) charge for energy on SC 2-EVC 285?

The modeled rates are 21.2¢/kWh–27.5¢/kWh by time of day. At the model's default time-of-use mix (30% peak, 45% off-peak, 25% super-off-peak) that blends to 24.6¢/kWh.

Does SC 2-EVC 285 carry a demand charge?

No separable demand charge is billed under the modeled structure — the cost sits in the energy rates instead.

What does electricity cost per kWh dispensed on this tariff?

For the reference site — 8 Tesla V4 stalls dispensing 235 kWh per stall per day, with a 12% loss gross-up — the all-in utility cost works out to 27.6¢/kWh per dispensed kWh, rank 32 of 96 tariffs in the library (1 = least expensive).
