Tesla Supercharger ROI in Pennsylvania
Pennsylvania is a deregulated electricity state with an in-force per-kWh tax on public charging, no tax on business equipment, and a corporate rate on a fixed downward path. ForgeAsset models PPL Electric's GS-3 tariff — distribution charges plus a competitive-supply benchmark — against Pennsylvania's tax stack, including the alternative fuels tax on dispensed electricity as a modeled operating line.
What makes Pennsylvania economics distinct
An in-force per-kWh charging tax
Pennsylvania taxes electricity dispensed at commercial charging stations directly. The alternative fuels tax is $0.0172 per kilowatt-hour for 2026, set annually on a gasoline-gallon-equivalent basis and published in the Pennsylvania Bulletin. A public charging operator is a dealer-user who remits monthly under a permit; residential charging was carved out in 2025, but public and commercial stations remain taxable. The model carries this as an operating line from the first year.
Deregulated, shoppable supply
Pennsylvania has been a deregulated retail electricity market since 1996. The Price to Compare is the utility's default supply rate — a benchmark, not a mandated price — reset quarterly through PPL's auctions. A large charging site typically buys competitive supply on a fixed 12-to-36-month term, so Pennsylvania economics depend on a locked supply-contract assumption rather than a single filed rate. The model uses the Price to Compare as a documented proxy for that contract.
No tax on the equipment, a real tax on the output
Pennsylvania's assessment law excludes machinery, equipment, and business personal property from property tax — only real estate is taxed. A DC fast-charging site carries no annual property-tax exposure on its hardware, trading that for the transparent, published per-kWh alternative fuels tax on every dispensed session.
A corporate rate on a known downward path
Pennsylvania's corporate net income tax steps down 0.5 points a year — 7.49% in 2026, reaching 4.99% by 2031 — under legislation enacted in 2022. The exact future rate is fixed in statute for each year of a hold period, which is unusually easy to model into a multi-year projection. Corporate income tax is disclosure-only in the engine, consistent with how state income tax is treated everywhere.

Pennsylvania tax profile
- Sales tax on hardware: 6%
- Business personal property tax: none
- Clean-fuels credit: no program
- Per-kWh charging excise: 1.7¢/kWh (in force)
Pennsylvania tax defaults applied: no clean-fuels credit program exists in Pennsylvania (the LCFS revenue line is $0), Pennsylvania does not tax business personal property, LLC costs use the $7/yr annual report, and sales tax is 6% in PPL territory. Pennsylvania's Alternative Fuels Tax applies to electricity dispensed at commercial charging stations — $0.0172/kWh for 2026, included as the energy-excise line from year one; the rate resets each January and the field is editable in Step 3. At default volumes the tax is on the order of $13,000 per year. State corporate net income tax (7.49% in 2026, stepping down to 4.99% by 2031) is not modeled, like state income tax generally.
Pennsylvania programs and incentives
Alternative fuels tax (a cost, not an incentive)
$0.0172 per kilowatt-hour for 2026 on electricity dispensed at public charging stations, remitted monthly by the operating dealer-user under a permit, reset annually. Carried in the model as a per-kWh operating line from year one.
NEVI (federal, PennDOT-administered)
A total program award around $171.5 million, with about $36.5 million in the FFY2026 formula allocation; PennDOT reports one of the largest counts of operational NEVI-funded stations nationally, plus a separate state announcement of $100 million for community EV chargers.
Driving PA Forward (Volkswagen settlement)
The Level 2 rebate program closed to new applicants in September 2023 with a waitlist; current DC fast-charging-specific availability was not confirmed. Verify status with PA DEP before relying on it for a site.
Pennsylvania charging market
Pennsylvania carries roughly 111 Supercharger stations across the I-76, I-80, I-81, and I-95 corridors. ForgeAsset models the PPL Electric territory — the Lehigh Valley, Northeastern and Central Pennsylvania (Allentown, Scranton, Harrisburg, Lancaster) — while Philadelphia (PECO) and Pittsburgh (Duquesne Light) run on different utility tariffs not yet in the library.
Pennsylvania Supercharger ROI — questions
- Does Pennsylvania tax public EV charging per kilowatt-hour?
- Yes. The alternative fuels tax is $0.0172 per kilowatt-hour for 2026 on electricity dispensed at public charging stations, remitted monthly by the operating dealer-user under a permit and reset annually. Residential charging was exempted in 2025; public and commercial stations remain taxable. The model carries it as an operating line from the first year.
- Why does Pennsylvania depend on a supply-contract assumption?
- Pennsylvania's electricity market is deregulated, so generation supply is bought competitively rather than set by a single filed tariff. The model uses PPL's published Price to Compare as a documented proxy for a competitive fixed-supply contract, which resets quarterly.
- Does Pennsylvania tax charging equipment as property?
- No. Pennsylvania's assessment law taxes only real estate, not machinery, equipment, or business personal property, so a charging site's hardware carries no annual property-tax exposure. The model sets the business-personal-property line to zero for Pennsylvania.
