Jerry,
That's the easy answer but this all gets really deep into
weeds as unless you're a PG&E smart meter (and we /really/ 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.
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.
I would love to talk to wrenches who can help me with
decent rates for AG pumping and the AG-solar destroyer: demand charges.

Currently with PG&E , you buy and sell at what ever rate you are on,
Peak = peak, off peak =off peak,

Friends:
After years of not quite understanding the intricacies of the newer,
more complicated utility rate schedules I have spent the last 72 hours
diving deeply into the rabbit hole. I have one question I need
answered. Maybe someone has the answer.
If you are on a tiered electric utility rate I know you pay more for
energy after you exceed certain daily amounts—the 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?
Is it: You get the baseline rate no matter how much energy you export.
Or is it: After you export more than the baseline rate, you start
getting credited at the over-baseline rate.
Or is it something different altogether.
If anyone knows the answer to this arcane question I would be very
grateful to learn it. It may vary from utility to utility or plan to
plan. PG&E E-6 is the tiered rate I most commonly encounter.
If any of you are particularly masochistic you can review some work I
have published on the subject here:
https://millersolar.com/MillerSolar/case_studies/28_UtilityRates/UtilityRates.html
<https://millersolar.com/MillerSolar/case_studies/28_UtilityRates/UtilityRates.html>
This is an intricate subject and I believe anyone working in grid-tied
solar should have at least a passing familiarity with the topic. It
affects the realized benefits of investing in grid-tied solar.
Thanks again for being the great group of friends that you are.
