<p>Jerry,</p>
<p> That's the easy answer but this all gets really deep
into weeds as unless you're a PG&E smart meter (and we <i>really</i>
trust them), you don't know when that E-6 baseline is crossed to
know when you're getting or paying the higher rate. There's 2
things going on, baseline and time-of-use. Customer usage, cloudy
days plus other variables make a precise calculation impossible.
A customer might enter the higher-than-baseline rate halfway into
the month and then low consumption and sunny days pulls the
customer back below baseline, paying the lower rate.</p>
<p> So many headaches, William, I've tried to figure all
this out on paper but have relied more on raw experience of what
works to zero-out one's bill which with E6 can easily happen with
less KWhrs produced than consumed.</p>
<p> I would love to talk to wrenches who can help me with
decent rates for AG pumping and the AG-solar destroyer: demand
charges.</p>

you are on a tiered electric utility rate I know you pay more
for energy after you exceed certain daily amounts\u2014the baseline.
I am clear that if you avoid paying the higher rates, the value
of the energy you generate is equal to the money you save.
However if you ratchet your daily usage below zero and are
net-exporting for part of a day, at what value are you credited
in an NEM contract?</span></p>
