Will this site pencil? Find out in seconds.
Drop in any commercial address and get a sourced, confidence-scored read on cost of power, demand charges, incentives, interconnection and permitting for your next DC-fast or Level 2 charging site — in seconds. Qualify a pipeline in an afternoon, and spend survey, title and study dollars only on the sites that pencil — that clear your return hurdle.

Balanced — workable payback, no single risk dominates. Every figure sourced & dated.
Enterprise tools price you out.
Free databases are stale.
If you run a lean shop, neither end of the market fits. SiteLitmus is the in-between: a real engine, self-serve, and priced for operators who just need to know if a site is worth pursuing.
Aurora, Energy Toolbase, Arcadia — powerful, but overkill (and over budget) for a first-look screen, with onboarding and implementation.
A real computational engine (time-of-use, demand, tiered and net-metering rates) at the address level — unbundled, self-serve, confidence-scored. Run just the check you need, or the whole stack.
Generic lookups miss demand charges (the utility's fee for your peak kW), time-of-use pricing and the most-favorable tariff the site actually qualifies for — the things that really move a pro forma (the project's profit model).
The modules
Each module answers one make-or-break question and returns a screening-grade card — sourced, dated and confidence-scored. Run the whole stack, or just the check you need.
Cost of Power
The true, all-in blended ¢/kWh under the cheapest tariff the site qualifies for — energy, demand, time-of-use, tiers and net metering. The number that makes or breaks the pro forma, computed — not looked up.
How it works →Incentives
Federal + state/utility incentives the site qualifies for — investment tax credit (ITC) adders, depreciation, grants — with eligibility and dates.
How it works →Interconnection
How much power the site can export, the metering setup and the primary-vs-secondary voltage threshold — what you can know before calling the utility.
How it works →Permitting
The AHJ (local permitting authority), adopted code cycle, plan-review path and battery/ESS fire-code requirements — mapped from the address.
How it works →Site & Land Diligence
Flood zone, contamination proximity, topography, utility lines and ownership — federal public data, instantly.
How it works →Charging revenue roadmap
The money side of the port: session pricing, utilization ramp and throughput economics, benchmarked against real operating DC-fast stations.
How it works →Built only for EV charging: every module is tuned for DC-fast and Level 2 sites — demand charges, utilization economics, metering class, switchboard and AHJ requirements. Screen an EV site →

The fastest honest read on a site.
Seconds, not weeks
Address in, answer out. No onboarding, no implementation, no sales call to get started.
A real engine, not a lookup
Time-of-use, demand, tiered and net-metering rates at the address level — the cheapest tariff the site qualifies for, not a generic average.
Confidence-scored & sourced
Every figure carries a 1–5 confidence score and an as-of date, with the source one click away. That's the litmus.
Lean teams screening real sites.
EV-charging developers
Check demand charges, utilization economics, metering and permitting for DC-fast and Level 2 (DCFC/L2) charging sites in minutes — then pull the DD workbook and project timeline.
Fleet & depot operators
Size the service, demand charges and utilization economics for a depot charging build before committing capital.
Energy consultants & brokers
Give clients a fast, defensible first look — sourced and dated — without an enterprise seat.
EPCs & site selectors
Qualify or kill sites early so engineering time goes only to the ones that pencil.
No black boxes.
Every figure shows its work.
SiteLitmus is in founding-user beta — so instead of borrowed logos, here's the proof that actually matters for a de-risking tool: the reasons you can put a screen in front of your IC or lender.
Sourced & dated
Every result links to its public source and the date it was last verified — utility tariff sheets, HIFLD, FEMA, EPA, USGS.
Confidence-scored
A 1–5 score on every card tells you how far to lean on it. We flag uncertainty instead of faking precision.

Answers, sourced.
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 and as-of dated, with the method and public source one click away.
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.
Which utilities and states are covered? +
185 curated commercial tariffs across 50 states + DC, backstopped by the public U.S. Utility Rate Database. See coverage →
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.
