High Falls Hydro Plant

Technical Information about High Falls plant

Example Formula For Pa y:
500 kilowwatt hours of output X 24 hours per day x 365 days/year x weighted average
from utility of about 5 pennies per kilowwatt hour = Anual Pa y if the plant ran all of the time.
A well run plant, in a good water year, can approch 60 % of the time overall.

Calculate: 500KW x 24 x 365 days x 5 pennies = $219,000 with 100% run time
= $131,400 with 60% run time

A Word from the Developers

These are very good plants with plenty of potential. They are being sold because the owners have other interest that commands their time.

"making pennies while you sleep and still making pennies when you wake up"

Example Formula For Pay. This Plant can be Expanded to 1,150 KW

The High Falls Plant is Developed for 650 KW Output:


650 kilowwatt hours of output X 24 hours per day x 365 days/year x weighted average from utility of about 5 pennies per kilowwatt hour = Anual Pay if the plant ran all of the time. A well run plant, in a good water year, can approch 60 % of the time overall.

Calculate: 650 KW x 24 x 365 days x 5 pennies = $284,700 with 100% run time = $170,820 with 60% run time

If expanded to 1150 KW with a 50% overall running time

Calculate: 1150 KW x 24 x 365 x 5 pennies = $503,700 with 100% run time = 251,850 with 50% run time



Example Formula For Pay. This Plant can be Expanded to 1,000 KW

The Little River Plant is Developed for 700: KW Output:


700 kilowwatt hours of output X 24 hours per day x 365 days/year x weighted average from utility of about 5 pennies per kilowwatt hour = Anual Pay if the plant ran all of the time. A well run plant, in a good water year, can approch 60 % of the time overall.

Calculate: 700 KW x 24 x 365 days x 5 pennies = $306,600 with 100% run time
= $183,960 with 60% run time

If expanded to 1000 KW with a 50% run time

Calculate: 1000 KW x 24 x 365 x 5 pennies = $438,000 with 100% run time x 50% = $219,000 with 50% run time.



These plants are only about 25 miles apart. These could be run with 1 operator going back and forth.
Most months of operation, on Duke Energy's statement of our income, if you divide our net income by
the total hours produced, the result is usually around 7 pennies.

We are not running the plants at full potential. For instance, The High Falls Plant ran basically 200 KW for most of last month. That brought in over $8000. For over 60 % of the month, there was enough water to run 400 KW to 600 KW. That can be seen on the USGS charts above. The head/horse power at High Falls works out to right at 1 cfs of water per 1 KW produced.



The Little River Plant ran basically 100 KW for most of last month. That brought in over $4000. For over 20 % of the month, there was enough water to run 300 KW to 750 KW. The head/horse power at Little River works out to right at 1 cfs per 2.5 KW. The higher head really makes a difference.

There are times like last month that having an extra operator, so that checking for sticks and logs, cleaning out wheels from debris, changing outputs, cranking another unit from change in flows, etc. are justified by, many times over doubling the income. We have not done that this season. All 4 partners are pulled in different directions in other businesses. The automation that we are working on to be able to run the plants from a laptop, excepting someone to come in to check on things and clean up trash/debris, will help that.



These are really good plants and easy to expand. We are getting prices in now on a new additional 400 KW unit, from over seas, for high flows at High Falls. Another draft tube is already installed at the Little River Plant for up to an additional 250 KW. The draft tube is the toughest part of expanding. Another Switch gear panel is sitting/waiting at Little River for the next unit. No reason to see these plants as suspect.These plants only need new owners that go in and run them the way they should be and expand them as soon as they can. Bring any Hydraulic Engineer to inspect anything. We will drain the plants, you inspect, and then crank up while you are there. You will be able to stand a nickel out of your pocket, edge ways on any main bearing housing, on any unit, thru half gate, full gate, emergency shut down, etc. We are good at this game, but it's just simply time for us to move on. If you need help with the plants, I'll be glad to help within reason, but I can't do to much physical labor any more.



However, phone calls, being able to have us come to the site and help design things, trouble shoot, oversee installation, etc. can be helpful if at reasonable rates. This is one of the few absentee owner businesses, out there, but it is mechanical, and occasionally things do break or go wrong. After 33 years in hydro, designing and building 7 plants, I really hate to get out. Health has a lot to do with it and the rest is bigger dollar interest in other things we are already in.

Thank you so much for considering our plants. Come see us when you can, you're always welcome.

For your Information- the Quick Pocket Formula used by the Corps of Engineers for figuring potential for any hydro site. This is to calculate the top reasonable development size in KW hours.



It has been years since we were into this formula deep enough to remember the individual components comprised in the 11.8 factor in this formula, but at that time, we had satisfied ourselves that the factor was justified and appropriate. It served us well for all those years, we did not find reason to challenge it.



Net head x average annual flow x 1.25 divided by 11.8 = total capacity a plant should be built to.


For example, at High Falls: 16 ft. net head x 692 cfs ave annual flow x 1.25 over build for flood flows
divided by 11.8 = 1172 KW


A local utility company considered developing the High Falls Site themselves, before we bought it. We built everything there, starting in the river bed with foundations.
I am including the factory Charts (many years old) for horse power/head/waterflow requirement/design for your research.

These charts apply to a 30 inch S wheel at High Falls and Little River as well as a 36 inch Z wheel at High Falls. These will give you some idea of how our calculations were derived. These came from an engineer's widow"s attic when we were agressively seeking hydro information. I hope these will help you to see how it all works.

Feburary 13, 2016. Addition of new Top Water Leaf Skimmer. 24 inch diameter pipe mounted with bottom of pipe 30 inches below top water el. when spillway on dam is dry. That puts the top of the pipe 6 inches below water level in canal. Open hydraulically, and skims top water leaves off with out shutting plant down to use bypass gate at bottom of trashracks. Works great.

First 2 pictures above is showing inlet to skimmer pipe and gate with coffer dam in front while we were installing. Third picture above is showing new skimmer gate, far right, and the green cylinder goes to the bypass gate at bottom toe of trash racks. The bottom bypass pipe is 3 ft. diameter and the top water skimmer is 2 ft. diameter.

2/15/16 Numbers just came in for last month, approx. $11,000 for high falls and approx. $7,000 for Little River. The numbers on High Falls could have near doubled if we had the 2 nd. (largest turbine) running. We have not run it in a long time, linkage problems. We are planning to tear it down/repair and put it back on line as soon as the water goes down. Really hate not to use the water while it is here.

4/10/16 Numbers for last month were about the same, about $ 20,000 for both plants. I am trying to add the charts from the utility company here, If I can figure out how.

10/10/17 High Falls is now under contract for 90 days. It will be back on the market in the month of December if the buyer does not close.


10/25/17 Little River is now under contract for 90 days. It will be back on the market in the month of February or sooner if the buyer does not close.


Little River Hydro Plant

Technical Information for Little River plant

Example Formula For Pa y:
500 kilowwatt hours of output X 24 hours per day x 365 days/year x weighted average
from utility of about 5 pennies per kilowwatt hour = Anual Pa y if the plant ran all of the time.
A well run plant, in a good water year, can approch 60 % of the time overall.

Calculate: 500KW x 24 x 365 days x 5 pennies = $219,000 with 100% run time
= $131,400 with 60% run time
