You certainly have more patience than I but can't say more than that for fear of being chastised for being " Political".

How much to you envisage this project saving you on power a year and what do you estimate the payback time on your investment?

I'll have a better idea of the payback once I get it into the water and see how it works. I'm pretty sure I'll cover my own electrical needs. How much I'll export is the question.

Hello Skid,

Any news regarding your project? The time really passes and i'd love to hear more recent news  :)

Cheers,

It's been a while, but I have some good news. The gov't regulators gave me the go ahead to install the wheel. The problem is they gave it to me too late in the spring and now the freshet is on with river levels so high I can't install my foundation. Once the freshet subsides, hopefully in a month or so, I'll complete the foundation and install the wheel.

It's unfortunate as river flows are high and steady and I could probably be making full production right now.

I still have a couple of things to complete. The hydraulic system for one which will take me a day, and the final underground splice on my power cable from the river to my house. I'm watching ebay for a 6 AWG armored cable kit so I don't have to pay retail for one. I hope to have those completed in July.

The other good news for me is that the regulator has reclassified this project as a commercial project instead of a home generation project. Amazingly this will cost me only $105 in annual water license fees instead of the $1500 I was facing before. This may help return the cost of this before I die ::)

I don't understand how a commercial classification can be cheaper than a domestic one but I am glad their stupidity has finally turned in your favour.
The whole thing of charging you for using the water was ridiculous to start with.  They will come up with any BS to get money no matter how illogical the reasoning.

I look forward to seeing further updates and some vids of the thing when it is running.

You might go looking for Welder's cable.

There have been many posts on here about using that with 1/2 the costs, and same power handling abilities ;-)

Very nice project ! I look forward to the next set of posts too.

Thanks Bruce,

I have enough cable, it's just that because of the total length (around 200 Meters), I have to install a couple of splices. I got the cable for free - three ~75 meter pieces left over from a underground power line project from work.

It's actually a bit of overkill as it is 5kv rated armored wire, and the Raychem splice kits are expensive if I buy retail. I've installed one already and just bought one from ebay for $100 so I'm good to go now.

I was going to mount the hydraulics that raise and lower the wheel on the water wheel frame, but have now decided to mount the hydraulic pump/battery and solar panel remotely on a nearby panel and run longer hoses to the hydraulic ram on the frame.

In addition I'm going to install 3 voltage/amperage gauges with CT's to measure amperage and voltage on each phase in the same panel so I can optimize the depth of the wheel for maximum output when testing and when river levels change. I've got an outdoor rated enclosure, and just have to install the components and make a frame to mount it on.

Earlier this week I had an excavator clear a path to the river to allow cement trucks to get to the site to pour the concrete and to allow moving the works to install once the foundation is complete. One of the conditions of the water license was getting a professional engineer to design the foundation. The foundation will require about 14 cubic meters of concrete (3x3x1.5 meters) which is about two trucks worth, and will be keyed into the river bank as originally planned.

Today I started to mock up the hydraulics for raising/lowering the wheel. I am repurposing a nice water tight electrical enclosure for the hydraulic motor/reservoir, the battery and solar panel, as well as the electronics that will measure the output of the generator. I'm still waiting for my ammeters from ebay but can mount the motor/reservoir and battery as well as the hard piping. It will be a little tight, and if I have to add oil I will need to use a syringe as the fill cap will be right at the top. This is the only way I can get it to work and the enclosure was free.

Plumb a fill cap onto the top of the enclosure. Use a fitting with rubber gaskets so it doesn't let water in.
