Utility Health Score
Pick one of 11 plant utilities, enter the readings you can measure, and get a weighted 0–100 score with the readings that pulled it down, suggested next checks and dated trends. Leave a field empty to skip a reading you cannot take.
Readings — Biomass Power Plant
Ideal bands are typical illustrations; verify with the OEM manual. Leave a field empty to skip it.
Ideal: 10–25 · Acceptable: 5–40 · Weight 3. Representative fuel sample; wet fuel wastes bed heat.
Ideal: 3–6 · Acceptable: 2–8 · Weight 2. Combustion tuning is fuel- and OEM-specific and needs qualified staff.
Ideal: 80–88 · Acceptable: 75–90 · Weight 4. Indirect-method or OEM-test efficiency.
Ideal: 95–105 · Acceptable: 90–110 · Weight 4 · critical. Enter the design values and score the achieved percentage.
Ideal: 800–950 · Acceptable: 700–1000 · Weight 2. Bed or furnace thermocouple at stable firing.
Ideal: 0–5 · Acceptable: 0–10 · Weight 2. Bottom-ash or fly-ash loss-on-ignition test.
Ideal: 60–95 · Acceptable: 40–105 · Weight 2. Induced-draught fan amps; high current suggests fouling.
Ideal: 0–4.5 · Acceptable: 0–7.1 · Weight 5 · critical. ISO 10816 guidance; zone C/D needs action.
Ideal: 0–5 · Acceptable: 0–10 · Weight 3. Feedwater cation or specific conductivity per OEM chemistry limits.
Enter readings and calculate a score. Empty fields are skipped and noted in the result.
How the score works
Each parameter has an ideal band (green, 100 points) inside an acceptable band (amber, 50–99 points, scaled). Beyond the acceptable band the reading turns red (0–49 points). Parameters carry weights from 1 to 5, so a weighted average decides the overall score: Healthy 80+, Watch 60–79, At risk 40–59, Critical below 40. If any critical parameter — marked with an asterisk — turns red, the overall score is capped at 49 and the result shows “Critical attention needed”, because a critical reading such as a low fire-water tank or out-of-band boiler-water chemistry is more urgent than the average suggests.
Parameters marked “design” score against a design value you enter instead of the generic band — for example, your consent COD limit, your machine’s rated heat rate or your chiller’s design head pressure. Skipped readings are excluded and the result states how many parameters were used, so a score built on three readings is visibly weaker evidence than one built on ten.
The seeded bands are typical industry illustrations and each one is labelled “verify with the OEM manual”. The owner edits every band, weight and critical flag in the tool settings without code changes.

A green score never certifies equipment condition and never replaces OEM limits, permits or site procedures.
