Questions, answered.
Everything an EV-charging developer asks before running their first site. Still stuck? Talk to us.
Is SiteLitmus built for EV charging? +
Yes — built only for EV charging. Every module is tuned for DC fast (DCFC) and Level 2 charging sites: demand-charge and utilization economics, the most-favorable EV rate, switchboard and metering class, interconnection, EV permitting (NEC 625, ADA stalls, site planning) and the full development timeline.
How accurate is a screen? +
Screening-grade — built to tell you which sites deserve real engineering and utility studies, not to replace them. Every result is confidence-scored (1–5) and as-of dated, with the method and public source one click away. The cost-of-power engine resolves the serving utility and applies the most-favorable qualifying commercial tariff (energy, demand, time-of-use, tiers and net metering) rather than a generic average.
Do I need to install or onboard anything? +
No. Type an address and you get an answer in seconds — no login to start, no implementation, no demo required to begin.
Which utilities and states are covered? +
185 curated commercial tariffs across 50 states + DC, backstopped by the public U.S. Utility Rate Database. See the live list on the coverage page, and request a utility if yours isn't curated yet.
How is this different from Aurora or Energy Toolbase? +
Those are powerful full-design suites at $159–259/user/mo with onboarding. SiteLitmus is a self-serve screening tool — unbundled, address-level, confidence-scored — free while in beta and built for lean teams that just need a fast go/no-go. Use SiteLitmus to decide which sites are worth opening a design tool for.
What data sources do you use? +
Public, citable sources: utility tariff sheets + OpenEI USURDB, HIFLD electric service territories, FEMA flood layers, EPA contamination data, USGS 3DEP topography, utility hosting-capacity (ICA) maps, and published incentive, NEM and permitting rules. Every figure shows its source and an as-of date. See the methodology.
Can I use the report with my IC, lender or EPC? +
Yes. SiteLitmus generates a branded Site Feasibility Report PDF — every module sourced and dated — built to hand to an investment committee, lender or EPC as a screening-grade first look. See a sample report →
Is this a utility commitment or engineering advice? +
No. Results are screening-grade estimates from public data to derisk an early decision — not a utility commitment, an appraisal, or engineering / legal advice. Verify locally and with the utility before committing capital.
What does it cost? +
Screening is free and unlimited — verdict, score, cost of power, comps, on any address. The comprehensive layer (cited due-diligence workbook, researched fields, custom timeline, plan set and branded PDF) unlocks per site: $99, or ~$70 each on credit packs that never expire. The Pro forecasting platform is $199/mo with ~25 runs included. Everything is free during beta. See pricing.
