<br><font size=2 face="sans-serif">Hi All,</font>
<br><font size=2 face="sans-serif">Following this post with much interest,
as this affects everyone that wants to reduce reliance on a utility grid
</font>
<br><font size=2 face="sans-serif"> that is already overburdened,
If TOU metering was done away with, it would eliminate "buy low and
sell high", </font>
<br><font size=2 face="sans-serif">which is a "wash" when you
consider battery replacement cost (due to excessive cycling).</font>
<br><font size=2 face="sans-serif">GTBB is an excellent way for individuals
to "do their part" in conserving energy. The fact that utility
companies </font>
<br><font size=2 face="sans-serif">are putting up such a battle is indicative
of one thing.....money (is there any other motive?). Everyone concerned
</font>
<br><font size=2 face="sans-serif">should contact their lawmakers in Congress
to pass a federal law so these utility companies will stop obstructing
</font>
<br><font size=2 face="sans-serif">clean energy.</font>
<br><font size=2 face="sans-serif">Rgds,<br>

in our "Intro to Off-Grid" classes.....we usually end up around
35 to 70 cents per kWh. </font>

<br><font size=3>Or another way to put it....a monthly 'battery bill' of
$25 to $120 depending on battery bank size, and how many years they pamper
it to last....or torture it to premature death.</font>

<br><font size=3>Just to add to Phil's comments: I've been calculating
total life cost of battery storage (KWH x cycle life x %DOD) and
the costs are 15 to 35 cents/ KWH to cycle a battery. Its even higher
for sealed batteries and Li+. It would have to be an amazing cost
difference in the TOU rates to beat the battery cost plus all the losses
of AC charging/ discharging a battery.<br>
I agree with Phil, as I've seen utilities obstruct solar since the 1980s.
Unfortunately their attitude has still not changed.<br>
Its pretty dumb too; battery storage could help improve the reliability
of the grid.<br>
You can't retire yet folks, we have another battle to fight.<br>

<br><font size=3> However, arbitrage (buying low and selling high)
is one of the lousiest economic models for energy storage. Yes, perhaps
you can make a buck or two if the delta is big enough. However, that's
like driving forty miles in your 4x4 to use a dollar coupon instead of
shopping at the grocery store down the block. There are just better ways
to make a buck.<br>
<br>
At the end of the day, what should matter in NEM is what generated the
energy that is exported. The customer should be able to maintain their
battery by charging from grid, solar, or any combination. The batteries
are not a balloon -- energy used to charge them doesn't come rushing back
out. Batteries are like a bucket -- if the inverter can only sell what
flows over the top, then it takes solar input to begin flowing.<br>

Ultimately, it's going to take a chorus of voices to get the CPUC to tell
the utilities to shape up and stop obstructing these systems. If
people stay silent, the utilities get their way. It's your industry, it's
your business. It's your choice.<br>
