Hydro Turbine Efficiency Check
Water-to-wire efficiency from measured flow, head and kW.
Water-to-wire truth: electrical kW out ÷ hydraulic kW in. Healthy plants run 60–80%; silty rivers grind runners down a point a year. Measure quarterly — the lost points are kWh you already paid for.
Trend this number, don't admire it once: runner erosion and seal wear shave efficiency a point a year in silty water — a 5-point drop is a refurbishment trigger that the energy lost already paid for.
Engineering estimate from published standards and typical equipment data. Site conditions, equipment datasheets and measured data govern the real result — confirm with a qualified engineer.

Frequently asked questions
What efficiency should a hydro turbine or pump achieve?+
Water-to-wire (turbines): 60–80% healthy, premium plants higher. Wire-to-water (pumps): 50–70% for matched systems. Below those bands, energy is leaking somewhere findable — wear, throttling, misapplication — and the diagnosis hints in this tool point where.
How do I measure system efficiency in the field?+
Simultaneously: flow (the measurement tools on this site), head/pressure (gauge or survey), and electrical power (the meter). For turbines: kW out ÷ (9.81×Q×H); for pumps: (9.81×Q×H) ÷ kW in. One honest afternoon of measurement; decades of better decisions.
My efficiency dropped over the years — is that normal?+
Decay is normal; ignoring it is expensive. Silt erodes runners (~1 point/yr in silty rivers), impellers wear, seals leak. A 5-point slide on a 50 kW plant is ~₹1 lakh/yr of energy — typically far more than the refurbishment that recovers it. The trend tells you when.
Efficiency or output — which should I monitor?+
Both, for different jobs: output (kWh) tracks revenue but confounds weather/water with machine health; efficiency isolates the machine. A wet month with falling efficiency is degradation hiding behind good revenue — exactly the case monthly efficiency logging catches.
