Master-metered communities [RE-wrenches]

[Mark Frye]

Bruce,

My current understanding of the problem you face is this:

The current master-meter is grandfathered in.  The baseline allocation is
based on the total number of units.  So if the territory allotment is 12kwh
baseline per unit and you had 100 units you got 1200kwh in baseline.

These old mater-meter rates are no longer available.

PG&E will let you put in the net-meter at the master meter, but you will
have to take E-6 TOU with only one units worth of baseline (12 kwh for the
example above).  Basically, the whole community would instantly be on TOU,
in tier 5, with only one little PV system to offset.

Hello All,

I'm wondering if anyone has experience to share about doing grid-tie  
in a master-metered community. We have a potential customer in a 100- 
unit senior community, that is master-metered, i.e one utility meter  
for the whole place, and each home having private meters through  
which they are billed by the "park". To do grid-tie, the master  
account would have to be converted to a net-metered account, and the  
customer would need a private bi-directional meter so they could be  
billed/credited by the park. I haven't been able yet to get PG&E to  
tell me if this is even possible. The park management is also saying  
that this would be an impossibly difficult billing arrangement for  
them. To my mind, this shouldn't be so hard (but what do I  
know. . .?). One, or even 5 or 10, units out of 100 would almost  
certainly never make the master meter go backwards, so that shouldn't  
need to be changed out. Has this ever been done?

Thanks,
Bruce
