SocalGas & SGIP for 3 PW

I'm receiving somewhat conflicting information on this, hoping people here with more recent experience and chime in.

I have 2PW already, would like to add a 3rd but wondering if I will qualify for the socalgas SGIP rebate on the third one.

My solar company said yes right away as there is now some 150% exclusion due to covid. Another solar company said if your solar system is not 3kW per PW than it is a automatic disqualification, not sure if that is true but my system is not 9kW or larger.

What is the requirement for 3 PW to receive the rebate?
Solar size requirement?
etc?

I contacted another solar company who said in order to qualify for the 3rd PW SGIP they need to show proof of 15kW/hour usage otherwise that alone is a gate for approval
Yep, each PW for SGIP has to show in their green button data at least 5 kw hour of home use during the last 12 months. So year, for 3, one has to show at least 15kwh of use during the last 12 months

Just crank everything on for at least an hour and see where you get to. (Solar off)
AC, space heaters, blow dryers, dryers, ovens; all add up quickly.

We run under 3kW routinely, often less than 0.3kW normally, but using the heavy draw appliances, we hit 22kW easily, and we didn't have everything on.

The data convinced our utility that 3 Powerwalls were warranted.

All the best,

I am not sure that you and @h2ofun are talking about the same thing (although the requirements might be the same). @h2ofun is likely talking about the SGIP equity and resiliency program, whereby powerwalls are paid for largely by the SGIP program (somewhere between 85% paid for to 100% paid for I believe).

@af88 appears to be talking about the "regular" SGIP (not the specific equity and resiliency "sub program"). These programs might have similar requirements for defining usage, and they might not. I dont know if they do, but I am fairly confident there are two different SGIP programs being talked about here.
 
I just received correspondence back from SCG and they stated 15kW/hour and it is for the "regular" SGIP as I mentioned in my email yesterday not the resiliency program.

I don't know if there is different requirements for the other program but for the regular program it is 15kW/h and I'm waiting to hear back how many data points they need to meet this criteria as you clearly will not be using 15kW/h at all hours. So based on the number of data points they require some might qualify, most will not if you are a low consumption user.

I need at least 1 hour of that in the last 12 months. I did 4 1.5 hours tests just to make sure I had enough data points when I submitted my green button data the second time.

How did you manage 15kW in an hour. I can't get anywhere near that even if i run the AC and all my appliances

How did you manage 15kW in an hour. I can't get anywhere near that even if i run the AC and all my appliances
10 heat pumps, 2 ovens, spa high speed, all lights, 8 TV, christmas tree lights, You name it, I had it running. I actually hit 35.2 at my highest.

You just have to do it for at least one hour, to generate green button data covering an hour showing that under some circumstances you do consume more than 15kW/h.

As I wrote before, try the AC, dryer, etc. and see what you get to. AC and electric heaters add up quickly.

All the best,

Can you link me to where this language is? to define the 15 kW "peak annual demand" for 3x Powerwalls?

My large-scale SGIP was submitted this way, and PG&E didn't seem to say anything. I can't find language that says the minimum actually experienced is 15,000 kW in an hour.

My greenbutton data peaked at 11.5 kW used in an hour through chance; I didn't realize I had to try and hit 15 kW.
