Has anybody considered charging storage batteries at off peak times and
co-gen (grid-tie) to put kWhs back into the system during peak rate times?
I understand PG&E's rate structure can be about three times the rate on-peak
as off peak. This sounds like it could be profitable for cheap "beat the
system" net metering.

I think a guy in the Guerrilla Solar column in the October/November 2001 issue
of Home Power
Magazine did just that. Had PV's charging a bank of batteries in his backyard,
but also took his
wind generator to work, erected it on the back of his truck before he went
inside to work. At the
end of his day, he took the batteries home and hooked them up to a Trace PS2512
and sold it back to
the grid.

Oops... I guess he sells it back during non-peak hours, eh? I just realized
that....

It is a great idea,
your dealing in watts and they are dealing with 10's of thousands of mega
watts.
Unless your planning on breaking the law the controls and protection
equipment for paralleling into the utility is high as well.
Nice thought some what impractical the way I think
