Evidence basis
Industry cases are built from public engineering references and transparent report logic.
Each industry case is written as a specific facility scenario with defined process scope, energy carriers, equipment behavior, calculation method, public method references and data fields that a user can replace with their own site values. Plant names are not shown.
Process boundary: what the plant makes or stores, and which utility loads belong to that boundary.
Energy baseline: electricity, fuel, thermal load, cooling load, compressed air and demand charge separated before totals.
Measure ownership: each saving is assigned to one measure path to reduce double counting.
Evidence level: site readings, trend data, utility bills, equipment data and maintained library factors are labeled separately.
M&V path: every report lists the field data that would improve confidence before investment approval.
Featured full examples

Each selected example starts from a different plant process, maps the energy carriers and then shows the report path that users can run with their own data.

Why engineers can trust it
Built for engineering conversations, not generic lead forms.
kWhScan is designed for plant engineers, energy consultants, ESCO teams and solution engineers who need a credible pre-audit report before spending time on site.
The report reads like an engineering pre-audit: baseline, saving measures, priority and next data to confirm.
Results are tied to the data you enter or import, so the review can move from screening to a more detailed audit.
Equipment, control, distribution and heat-recovery actions are shown separately so the project team can prioritize.
The sample report and free diagnosis come first. The paid report is a one-time US$29 unlock through Stripe, with no subscription.

Calculation basis
Transparent enough for screening, structured enough for a paid professional report.
kWhScan separates automatic screening, engineering estimates and downloadable report outputs, so users can see where each saving number comes from.
The assessment matches language and project region first. If a formal local rating table is not connected, it uses a documented international or project reference and labels it clearly.
Station efficiency, equipment selection, station control, distribution/end-use loss and multi-energy boundary are calculated separately before aggregation.
Savings keep their evidence source, calculation basis and overlap policy, so pressure, equipment and aftertreatment measures are not counted twice.
Implementation path

Fast field estimate
Use a few values that engineers can obtain on site to quantify the first saving range.
