Everything a developer asks before running their first site. Still stuck? Talk to us.
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, 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 to begin.
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.
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. Use SiteLitmus to decide which sites are worth opening a design tool for.
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.
Yes. Paid plans generate 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.
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.
Free to screen, unlimited. Paid plans run $29/report or $49/mo unlimited, with a team tier at $149/mo — and everything is free for founding users during beta. See pricing.
