Feasibility screening for clean-energy sites
Drop in any commercial address and SiteLitmus runs it through the test — true cost of power, incentives, interconnection, permitting and site risk — with a confidence score on every answer. Screening-grade due diligence before you spend a development dollar.
The gap
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 (TOU + demand + tiered + NEM/NBT) at the address level — unbundled, self-serve, confidence-scored. Buy just the check you need.
Generic lookups miss demand charges, time-of-use and the most-favorable qualifying tariff — the things that actually move a pro forma.
One address, every question
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.
The true, all-in blended ¢/kWh under the most-favorable qualifying tariff — energy, demand, TOU, tiers, NEM.
How it works →Federal + state/utility incentives the site qualifies for — ITC adders, depreciation, grants — with eligibility and dates.
How it works →Export headroom, metering sequence and the primary-vs-secondary threshold — what you can know before calling the utility.
How it works →The AHJ, adopted code cycle, plan-review path and ESS fire-code requirements — mapped from the address.
How it works →Flood zone, contamination proximity, topography, utility lines and ownership — federal public data, instantly.
How it works →The price you earn: NEM/net-billing, PPA / avoided-cost export value, RECs and EV session economics.
How it works →Why SiteLitmus
A litmus test gives you one clear answer, fast. That's the product: a screening-grade go/no-go you can actually trust, because every number shows its work.
Address in, answer out. No onboarding, no implementation, no sales call to get started.
TOU + demand + tiered + NEM/NBT at the address level — the most-favorable qualifying tariff, not a generic average.
Every figure carries a 1–5 confidence score and an as-of date, with the source one click away. That's the litmus.
Solar export value, battery savings, EV retail — the economics that decide a project, not just a rate.
Pay for the check you need, with a free screen to start. Priced for lean operators, not enterprises.
Screening-grade and clearly labeled — built to derisk a decision, never to oversell a site. Verify locally before you commit.
Built for
Screen a pipeline of C&I rooftops and BTM sites for cost of power, export headroom and incentives before site control.
Check demand charges, utilization economics, metering and permitting for DCFC/L2 sites in minutes.
Give clients a fast, defensible first look — sourced and dated — without an enterprise seat.
Qualify or kill sites early so engineering time goes only to the ones that pencil.
Common questions
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. The cost-of-power engine resolves the serving utility and applies the most-favorable qualifying commercial tariff (energy, demand, TOU, tiers, NEM) rather than a generic average.
No. Type an address and you get an answer in seconds — no login to start, no implementation, no demo required.
185 curated commercial tariffs across 50 states + DC, backstopped by the public U.S. Utility Rate Database. See the coverage page for the live list, and request a utility if yours isn't curated yet.
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 — priced for lean teams that just need a fast go/no-go.
Why developers trust the numbers
SiteLitmus is in founding-user beta, so instead of borrowed logos here's the proof that actually matters for a derisking tool — the reasons you can put a screen in front of your IC or lender.
Every result links to its public source and the date it was last verified — utility tariff sheets, HIFLD, FEMA, EPA, USGS.
A 1–5 score on every card tells you how far to lean on it. We flag uncertainty instead of faking precision.

Founders get the full Site Feasibility Report — every module, sourced and dated, in one branded PDF for your IC, lender or EPC — free during beta.
