Micro Hydro — Northeast India
Power and annual energy from head × flow × efficiency — ne india stream presets.
The Northeast holds India's richest small-hydro resource and its thinnest grid — village micro-hydro often beats wire-stringing economics outright. Monsoon abundance is never the question; February flow is.
NE India stream: every metre of head and every litre per second is power — 10 m × 100 L/s at 65% efficiency ≈ 6.4 kW, day and night. Hydro's magic is the availability: unlike solar's ~20%, a good stream runs 60–90% of the year.

Frequently asked questions
How much power can my stream generate?+
P(kW) = 9.81 × flow(m³/s) × head(m) × efficiency. Ten metres of drop with 100 L/s at 65% efficiency makes ~6.4 kW — continuously, day and night. Hydro's edge over solar is the hours: 60–90% availability versus ~20% — small kW, huge kWh.
What's more important — head or flow?+
They multiply, but head is the better friend: high head means small water, small pipes, small turbines (cheap Pelton wheels), while low-head sites need big flows and big civil works per kW. The classic rule: find the drop first, then measure the water.
Which flow measurement should I use for design?+
The dependable dry-season flow — the stream's worst honest month — not the monsoon spectacle. Design flow above dependable flow buys capacity that idles most of the year. The flow-measurement tools on this site (bucket, float, weir) make the measurement a weekend job.
What does micro hydro cost compared to solar?+
Site-dependent: ₹1.5–4 lakh/kW installed for good micro sites (vs solar's ~₹0.5/kW) — but hydro's 3–4× capacity factor and 30+ year civil life flip the per-kWh economics at decent sites. Run this tool's annual kWh against solar's for your location and the comparison settles itself.
