Hi Pete, Doug, and list.
Electricity Generation: Here in Manitoba, where Electricity is the cheapest in North America (0.06 kwh) it IS still feasible, the key to this is using 2 engine/generators. Two you say.... Let me explain, the interconnect equipment is the cost, the generators are cheap in comparison, one way to get around the high price of synchronous generation (the type of generator that produces simply by spinning it's shaft), is to use an "induction generator" when connected to the grid, and THEN, if the power fails use the synchronous generator as a stand alone, until grid power resumes. Induction generators ONLY make electricity IF the GRID is working, once the grid goes down, the generator simply spins, and no output; However, they are really easy and cheap to interconnect because of the non-need for synchronizing. On the other hand, Synchronous generation required VERY costly interface equipment, BUT as a "stand-alone" they generate when no other electricity is present. kindest regards, Greg Manning, Canadian Gasifier Ltd.

The Tecogen puts out 60 kwe on LPG, and from memory, I calculated we would get around 47 kWe on producer gas. As my job is to supervise the producer gas interfacing, (I'm still in NZ) next week, I can be more specific in my next report in December. > If its more than 5 or > 10 KW, please tell me about your grid connecting controller: cost, > mfr, etc.. All this stuff is built into the Tecogen CHP system, not clobbered up with off shelf componentry. These package plants are fully certified to meet Californian regulations, and came with a hefty price tag in the region of $80,000. I do know that there would have been some big charges from the power company to supply relay code settings if we had not had them fitted into the Tecogen. The economics of doing this power generation module are certainly outside of commercial realities, but my associates are looking for answers to questions, and prepared to pay for the experience. As the second objective of this particular project is to replace LPG as a heating source for glass houses, the gas has greater commercial value than for electrical generation, but we still have to meet all the emission regulations for it's combustion. Because the issues of grid connections can only be discussed in general terms, my opinion for what it is worth (nothing) , tells me that DIY gensets and grid relay connectors, will not be approved by most line companies, unless they can be certified appropriately, hardly economic for a few kWe. If that's all you can offer, then you are best suited to either use gasifiers for stand-by, or use all the power yourself on site.
