You are forgetting that netmetering is only with renewable fuels -- most
people are doing it with solar, wind, or hydro. If you want to do it with a
cogen setup, you have to fuel it with a renewable fuel, i.e., biodiesel (or SVO
- straight vegetable oil), ethanol, or woodgas. A few states allow you to use
natural gas if it is also a cogen setup, that is, you are utilizing the heat as
well as producing electric power.
So -- my fuel costs are zero. I can get all the SVO I want for free, likewise
woodchips to make woodgas. Even better, I can, if I want to expand and build a
bigger unit, say run a few 200kwe gensets or even get into gas turbines -- and I
do hope to do this if I can get the capital together -- start gasifying sewage
sludge to run the engines on. I not only can get all I want, in a nice, dry form
ready to gasify, but the city here, for example, will not only deliver it, but
pay me to take it as well.
Of course, if I produce over 20kwe, then I no longer get the retail rate,
only the wholsale rate, but since the fuel is free -- or even better, getting
paid a good bit to take the fuel, it still works out quite well. Right now, tree
trimmers have to pay to take their chips to the landfill. As do restaurants
their SVO. And citys are paying farmers to allow them to spread their sewage
sludge on the land, but that's not going to be allowed much longer, so there's
no end in sight for the fuel supply.
Or, for that matter, I could just buy a few hundred acres of marginal
farmland and plant it all to switchgrass or reed canary grass. Plant it once,
you never plow or plant again, or fertilze, just harvest and gasify and produce
power. Cattails is an even better source of biomass for gasification and
ethanol. With cattails I can even get paid to harvest them from state land
(cattails are considered an invasive species and they're spending a lot of money
trying to control them).
The economics of it look great, and will be improving rapidly as fossil fuel
costs continue to climb.
