Farm Pond Micro-PSP Calculator
Stored energy (V·ρ·g·H·η), release flow for target MW and runtime — farm pond storage.
Micro pumped-storage on farm ponds: pump up with midday solar, generate through the evening. 5,000 m³ over 30 m stores ~330 kWh — battery-scale storage from earthwork. The economics are emerging; the physics is here.
Farm pond storage: E = V·ρ·g·H·η. Water's energy density is humble (~2.7 Wh/m³ per metre of head) — which is why pumped storage needs mountains and reservoirs, and why a rooftop tank will never be a power bank. The release planner answers the operational question: how long can we run at X MW?
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
How much energy does stored water hold?+
E(kWh) = volume × 9.81 × head × efficiency ÷ 3.6×10⁶ — about 2.7 Wh per m³ per metre of head. A farm pond (5,000 m³) behind 30 m holds ~330 kWh; a pumped-storage upper lake (500,000 m³, 150 m) holds ~180 MWh. Head and volume multiply; neither alone suffices.
Why is pumped storage built despite 75–80% efficiency?+
Scale, lifetime and price: reservoirs store gigawatt-hours for 80–100 years with cheap civil works per kWh — batteries can't touch the duration economics. The 20–25% round-trip toll is paid happily for absorbing cheap midday solar and selling the evening peak.
Can a rooftop tank store meaningful energy?+
No — and this tool proves it kindly: 10,000 L at 15 m holds 0.33 kWh, a phone-bank's worth. Water storage is for water; energy storage needs either mountains of head or chemistry. The viral 'gravity battery at home' idea dies in one calculation here.
How do I plan reservoir releases for power?+
Invert the equation: flow for X MW = X×10⁶ ÷ (9.81 × head × efficiency). The runtime row then divides live storage by that flow — answering 'can we hold 2 MW through the evening peak?' in one screen. Real dispatch adds inflow forecasts and rule curves on top.
