I am working on an alternative energy invention combining WIND and SOLAR in one device.

A working prototype is built - but I need help with basic assumptions on the economics of the device.

I want to extrapolate from some very basic fundamentals and calculations - where the goal is to SELL the electrical energy produced.

THE HELP I am seeking from this FORUM is in CALCULATIONS and ASSUMPTIONS - not actual connections at this time.

This device (my invention) can be installed and tested anywhere in the US - and I am seeking the optimal RATE for the energy I produce [/b]and put into the grid.

If a 100-watt wind generator motor spins at an average consistent speed for 24 hours - what is the total wattage output for the creation of electricity - that if put into the grid I would be paid as an energy producer?

My device is small, light, and compact - AND can be installed in series for maximum power output - from 10 devices to 100 devices in a row.

My invention is a non-traditional installation or application and has a near-constant source of high-velocity wind

Assume I can sell excess power to the utility at $0.25/kWh.  (or suggest an alternative price paid today)

Once I have the basic economic assumptions - I can model for optimal output and change variables in the design such as changing the generator motor from 100-watt to 250-watt or 500-watt motors.

I need to work off of a 100-watt motor outputting electricity nearly constantly into the GRID over a 24-hour period to estimate KwH per day at a given rate.

My goal is to build the systems as MegaWatt installations for the purpose of these hypothetical applications to demonstrate the capacity to generate electricity.

Thanks for all of your questions, thoughts,  and ideas in my attempt to learn more!

I've played around with the idea of building some kinetic batteries. Anything you connect to the grid should be UL listed/certified, or CE marked. From what I understand Underwriters Laboratories is the way to go, and I've heard some people refer to CE "China Export"(EU license to import cheap Chinese garbage) as the mark of the beast in a less than joking manner.  My very rough outline of the system was to use a UL certified inverter for solar panels to take a DC input from my kinetic batteries, and use that to send power back into the grid.

The power companies around here (Pacific Power, Carbon Power and Light, and Yampa Valley Electric) all told me they don't want net metering on their grid. I don't know where you got your $0.25/kWh from, but right now I'm on Carbon Power and Light and I believe it's 14 or 17 cents per kWh. They legally can't stop you from net metering, but as far I've researched the problem I understand their concerns. The problem with these alternative energy sources is that during a week long winter storm the alternative energy sources don't produce well, and that's typically when energy use on the grid is really high. I ran some rough numbers to see what it would take to output 50A at 220V for a week, and it would take a lot of batteries. If the power companies were more, I don't know, forward thinking?, they'd allow someone like me to buy power cheap in front a a storm front, and then sell it back to them for a profit when the storm hit. A small scale solution could prove that a large scale solution would work. I think if you could guarantee power during a long storm, or low wind period the utility companies would be happy to have you around. Generation of power is less of a problem than storage of power is from what from I've researched.

It's not an easy problem to solve, and solving it would undoubtedly be profitable.

Good luck,
Peter

Big edit from me; oops, I misread the OP's idea.

I think you understand that 100 watts doesn't count for anything. I can buy more than that from Costco, off the rack, today. If you can generate, it, use it locally! Personally I think that's the sweet spot. But I'm also grid dependent, when it hits -46C and the windmills are still.

If you can scale this up, into the range of serious grid production,  I think you run into the same old problem of Big Grid -- you can't store it, and they can't rely on it because it's intermittent power and you'll be offline when they need it most.

But this calls for a demonstration project -- proof of concept. I wonder -- could you create a neighbourhood grid first, a charge my cell phone grid based on wind. And then if that succeeds, start poking potential partners with a stick -- see? this can work! Maybe they need the PR, if nothing else.

My 2c.

100 watts x 24 hours/day % 1000 W/kw = 2.4 kwhr per day

To get a million watts with 100 watt generators would require 10,000 generators.

Don't count your chickens before they've hatched.  No evidence yet that this will make a single watt.

Keep in mind that a 100W solar panel potentially may never actually make 100W in it's entire lifecycle.  As someone that is 100% relient on solar, I know the difference between labels and what I actually get.

Between connection fees, meter replacement, permitting fees, insurance, small scale net metering is usually a break even possibility at best without subsidy. It's done on purpose by grid owners. More and more jurisdictions are not paying actual money for power produced just issuing credits for kWhrs pumped in. At the mega watt scale sure money changes hand at the proof of concept stage not so much.
So, the work around to all that is not to feed the grid but to create a section of a home that operates on its own. It is called various things "grid zero" or " self consumption" are two common ones. You create a battery/ inverter combo that can accept input from various dc sources and use a grid connection only to top things up in case of shortages. Add dc sources until a balance is made, if you end up with a surplus add a good home dump load like a hot water heater, an AC, make ice, run a food dehydrator in floor radiant heat. Once you have a working proven product you could then pursue net metering if your area pays money. You would want a certified solar or wind element on said system to which you could add your as yet undescribed wind elements. You would be in a grey area legally but with some deniability. I've known woodgas enthusiasts who have done something similar.
