Preliminary hydro turbine design
Hydro turbine design optimization
From head and flow to feasible machine types, valid configurations and a downloadable spec sheet — in minutes, in the browser.
The problem
Every feasibility study starts the same way
Before any detailed design, you need to know which machine fits the site — and what it roughly costs. That answer usually lives in scattered correlations, old spreadsheets and tribal knowledge.
Scattered methods
Nomograms, papers and personal spreadsheets that rarely agree.
Hard to compare
Pelton vs Francis vs Kaplan vs screw — each evaluated by hand, separately.
Slow to a number
Days to a defensible preliminary power, speed and cost estimate.
How it works
Three steps, one defensible answer
Enter your site
Net head, design flow and grid frequency. That's all the engine needs to start.
Get feasible machines
Which turbine types fit, with valid configurations, speed, efficiency and runner geometry.
Export the spec sheet
A clean, costed, downloadable PDF — ready for your feasibility report.
Validated engineering
Built on a decade of turbomachinery design, validated against thousands of real sizings.
Pricing
Pay per sizing. Credits never expire.
Small sites are free. For professional sizings you buy credits — one credit per professional sizing, no subscription, no expiry.
Credits never expire · one credit per professional sizing · prices billed excluding VAT.
FAQ
Questions
What does HPP-Design do?+
It produces a preliminary design for a hydro site: given head and flow, it returns the feasible turbine types, valid configurations, performance and a rough cost — as a downloadable spec sheet.
Who is it for?+
Independent developers, engineers at utilities and EPCs, and technical universities — anyone who needs a fast, defensible preliminary sizing.
Which turbine types are supported?+
Pelton, Francis, Kaplan and Archimedean screw, across their valid head/flow ranges.
How accurate are the results?+
It's a preliminary sizing, not a detailed design — built on a decade of validated turbomachinery engineering and meant to get you to a defensible number fast.
Do credits expire?+
No. Credits never expire, and there's no subscription.
