PECO GS — EV fast-charging electricity cost

PECO GS is the filed rate schedule ForgeAsset models for DC fast-charging sites in PECO territory in Pennsylvania. Energy prices at 11.4¢/kWh flat; the demand side bills $15.45/kW of monthly peak. For one reference Supercharger site held constant across the whole library, that works out to 45.2¢/kWh per dispensed kWh — rank 58 of 86 filed tariffs (1 = least expensive).

Modeled rates

Flat bundled rate for a deregulated state: PECO's distribution charges plus its filed default-supply price, standing in for a competitive fixed supply contract — PECO's default service above 100 kW is hourly PJM pricing, so the fixed small-commercial price is the filed benchmark. Demand is billed per kW of the monthly measured maximum; the schedule's 40%-of-contract-demand floor resolves to the measured peak under the model's billed-peak assumption, and the demand rate folds the non-bypassable and default-service transmission charges. The supply benchmark resets 2026-12-01. PECO's EV-FC pilot rider — a 30% distribution-demand credit for public fast charging, capped at 36 months per site through May 2029 — is time-limited and not modeled. Pennsylvania's Alternative Fuels Tax on dispensed electricity (1.72¢/kWh in 2026) is carried on the tax-profile side, not in this rate; Philadelphia's local sales tax on electricity (+2 points) is site-dependent and not included.

The utility files an EV-specific rate or pilot that this model does not assume, so the modeled electricity cost reflects the standard schedule. A site that qualified for and enrolled in that program would see a lower demand line than the one modeled here. PECO's EV-FC pilot rider credits 30% of measured demand off the distribution demand charge for public fast-charging sites, but the credit runs at most 36 months per site and the pilot ends in May 2029, inside this model's 15-year horizon.

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 58 of 86.

The rest of the Pennsylvania picture

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

PECO GS — questions

What does PECO charge for energy on GS?

The modeled rates are 11.4¢/kWh flat. At the model's default time-of-use mix (30% peak, 45% off-peak, 25% super-off-peak) that blends to 11.4¢/kWh.

Does GS carry a demand charge?

Yes: $15.45/kW of monthly peak. For a reference 8-stall site at 150 kW per stall that comes to about $18,543 per month.

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 45.2¢/kWh per dispensed kWh, rank 58 of 86 tariffs in the library (1 = least expensive).
