Don't we all wish we had this on our property

Post by John in CR » Jul 17 2020 7:27pm

A new friend who want my help building a high powered ebike is also working on a hydroelectric project on his dairy farm that has an electric bill of over $1000/mo. It's up in the mountains at 4,000m of elevation and he has a small river with year-round flow and a whopping 200m of head :shock: . Even with just a 3" pipe he can produce an incredible amount of electricity at the 400gal/hr rate he is planning.

Hopefully he can negotiate a grid tie arrangement where he gets paid for the excess he generates.

ES member “craneplaneguy” has reported on his “mini hydro” system for several years. Avery nice to have facility.
Another member ( ? Aussie ? Forget name) has also reported on his DIY mini hydro working with limited head, but continuously outputting 1+kw to a large Pb bank, and also to a experimental “pumped hydro” tank system for storage.
Ideal if you have the land , water, and terrain to enable such a system.
This forum owes its existence to Justin of ebikes.ca

He does have some trout ponds fed with a continuous flow from the river, but no migratory fish to worry about.

He should be able to get about 2kW continuous, or about 1300kwhr/month. That should offset about $130 a month at 10 cents/kwhr.

Systems like this often use "wild AC" from generator to rectifier - voltage/frequency determined by RPM and regulated by a MPPT controller.

It's been a while since I did the research to confirm his estimate of 6kw continuous as a fairly conservative estimate, but it was more than enough to offset the $1k/mo electric bill for his dairy farm. Note that our 98% green electricity is nationalized, and despite being primarily hydro power, our cost per kwh is almost double your 10 cents. Too bad there's such corruption, because I have pleasant dreams of 2 cents/kwh in the areas supplied by hydro in parts of Canada. If I live long enough to see real global warming, maybe I'll head north to Canada, which would become the new farm belt of the west.

Hmm. 400 gal/hr is .42 liters per second. Are you sure that's right? That's a pretty small amount of water to run a hydro system with.

Ah, now I see where I went wrong on the original post. It's 400gpm not per hour. His river and waterfall have real flow, and then we both discounted each thing quite a lot to prove his desired 6kw seemed quite reasonable.

Oh, OK! Definitely agree then.
