I have talked with my installer and yep, they said in the past folks got whatever amount of batteries they asked for. But, not now.That might have been in the past, but I can assure you from my experience now and clearly with @h2ofun they are requiring that information now.
Each his own.
Ok so this topic was actually discussed on the SGIP workshop. Naturally this is my paraphrasing what I think I heard... I could be wrong.
They kind of contradicted themselves a bit since Residential and Non-Residential are treated differently.
One person said that with regard to the "peak annual demand" calc, they are now using a 3rd party provider (ASE?) to aggregate "greenbutton" data to confirm the "peak" demand for the SGIP assessment. Homeowners and Businesses no longer have to upload greenbutton data.
But another person said that residential applications still need someone to upload the greenbutton info.
Regardless, they said someone's going to look at it and tell you if you qualify or not. I couldn't get confirmation from anyone on whether or not a 15 kW ESS (regardless of resiliency, normal-large-scale, blah) needed a 15 kW peak in a given hour. They said "they'll tell you if you don't qualify".
Now, that makes no sense. That is exactly what the process is. Now, I would want 20.1kwh. But how can they say it does not qualify. It is 5khw per batterySomeone just opined and said that battery size actually has to be less than peak demand. So if your Greenbutton is 20kW peak in an hour ... you can't actually size up your battery to 20 kW (4 Powerwalls). This sounded like an issue for all SGIP categories large scale non-res... ER, blah blah.
I need to pop some Advil... this is beyond frustrating.

Yep, it has always been an hour or moreFWIW, SGIP responded to my inquiry and comments made during the SGIP webinar on Monday.
They say that even though I can demonstrate a burst (eg 15 minute interval) of needing 15 kW (60 Amps) during that interval... they need to measure the hour-long demand which clearly is not 15 kW since I never bothered to try and charge an EV while running my normal home loads.
Had I simply charged an EV for an hour while running my home loads, they'd go ahead and let me get the SGIP. Talk about BS. This is potentially going to cost me $8,700 simply because I didn't try and game their system with artificial loads or behavior to force a fake peak to emerge in my Greenbutton data.
Yep, it has always been an hour or more
I want to say I saw it in the SGIP handbook. Plus who ever you are working with should have known. Plus, on this site, it has been talked about many times.Where did you see this language for an hour or more? I poured through the docs and I even did the application on their form under my own developer key. I don't see this 60minutes/1hour language for large-scale SGIP or the Resiliency SGIP.

True, I would have just assumed no different, but ..... You have just run into so many issues. I am still waiting to see if I get the NEM stuff you got.The sizing has been talked about for Equity Resiliency, but not for large-scale energy projects.
