[RE-wrenches] Utitlity Rate question

[William Miller]

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:

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.
