Eversource (Eastern Massachusetts) Rate EV-2 — EV fast-charging electricity cost

Eversource MA Rate EV-2 is the filed rate schedule ForgeAsset models for DC fast-charging sites in Eversource territory in Massachusetts. Energy prices at 16.7¢/kWh flat; the demand side bills none. For one reference Supercharger site held constant across the whole library, that works out to 18.7¢/kWh per dispensed kWh — rank 8 of 86 filed tariffs (1 = least expensive).

Modeled rates

Eversource's filed EV-specific rate for Greater Boston: one of four demand prices is assigned from the site's measured load factor — from $0 per kilowatt-month below 5% up to about $15.50 above 15%, with a per-kWh distribution adder on the lowest and highest groups. The model derives the load factor from the projected energy and the billed peak, re-assigning the group each model year; the filed version assigns from trailing metered data. The first-decade discount phase-down is not modeled. Flat energy folds the published August–October 2026 default-supply strip and the 6.25% Massachusetts electricity sales tax; the fixed supply price is an election with a twelve-month term and six months' notice to exit. Rates re-derive at each quarterly strip.

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 8 of 86.

The rest of the Massachusetts picture

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

Eversource (Eastern Massachusetts) Rate EV-2 — questions

What does Eversource (Eastern Massachusetts) charge for energy on Rate EV-2?

The modeled rates are 16.7¢/kWh flat. At the model's default time-of-use mix (30% peak, 45% off-peak, 25% super-off-peak) that blends to 16.7¢/kWh.

Does Rate EV-2 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 18.7¢/kWh per dispensed kWh, rank 8 of 86 tariffs in the library (1 = least expensive).
