Hey Aaron,
Apologies on the delay here, we wanted to get confirmation from our regulatory
department.
These points stand on their own - Depending on what kind of service it is—commercial
or irrigation—it would require proof by way of either iii. or iv.
Have a good weekend!

Point iv is exceedingly interesting. A big pump might help us with this issue. Does iv
stand on its own or will peak demand still be a consideration if the system has been
there a long time?

Hey Aaron,
No need to cry! This is how the rule is defined in the schedule 84 tariff(Microsoft

As you can see, there is potential an option further review. Depending on what
kind of service it is—commercial or irrigation—it would require proof by way of
either iii. or iv.
I don't know if this helps or not, but the CG team though this update would be
helpful for you to be aware of given your question.
Thanks!

Hey Aaron,
No need to apologize—we are glad you asked!
To answer your question - No, there is no mechanism to apply for a slightly oversized
system. For the example you laid out, the maximum system size is the same as the peak
demand. So the largest system allowed would be 152.4 kW.
We are bound by the rules set in the tariff Schedule 84 tariff so there is no room for
exceptions.
Have a good weekend,

Team,

I'm sorry to keep beating on this issue,but I keep trying to come up with edge cases
that will and won't work.
Chris Unruh has a meter where the peak demand is 152.4kW. Based on consumption
over there,he could put in 4 of our 38.88kW arrays which max out at 155.52kW
nameplate; a mere 2% above peak demand. As you're aware, our systems use bifacial
solar panels, so their actual output is higher than nameplate sometimes. Presently,we
either have to put in 1 100kW inverter and 1 50kW inverter and curtail production all
the time or put in some slightly larger inverters that will only curtail some of the time.
A perfect configuration is having 3 60kW inverters which means 180kW nameplate or
about 18%above peak demand.
What I'm curious about is whether there is a mechanism for us to apply for a slightly
oversized system with justification; something like the scenario I described above.
Regards,
Aaron Pace
