Thanks to Vines for the reply. Will my project (8.1 kW panel, PWs for whole house backup) use the existing service panel? The current panel is 200A, with 4 breakers for 2 AC units, an oven and a sub panel.
I merged your new thread into this one since its the same topic, and this one has most of the information we know about this topic.
Something changed about the 36” rule between when I posted and today. Iirc vines said new equipment was allowed within 36 (but not within 18 inches) under certain criteria. It was supposed to make a MSP replacement even easier. Hopefully @Vines can elaborate.
So it seems that Tesla really doesn't want to do any project with any potential risk. I'm considering switching to another company, or going all electric. Now I have started a project to replace 20-year-old furnaces/ACs and a 10-year-old water heater with heat pumps. The remaining gas appliances are a 20-year-old dryer, a cooktop and 2 fireplaces (seldom used) which are easy to move away from gas.We (TESLA) are disqualifying the project as the relocation of the electrical panel is outside of our scope. Any new solar installation must abide by the PG&E Greenbook clearance requirements.
I am not saying you are doing this, but please don't pose your requests to Tesla "This guy vines on TMC is an installer and he said the rules are XXX"I replied to my Tesla advisor with the information from @Vines. They replied:

Thanks to everyone for the replies. I promise I didn't say anything about TMC or ids in the emails to Tesla. I have asked them to cancel the project (otherwise they will wait until Nov 8 to cancel it). It's weird that they had set a date of cancellation, but didn't tell me until I asked for updates (The last update was on Oct 5 to confirm the location of PWs). I have decided to find another company. This also gives me a chance to optimize the design e.g. with more solar panels.
Please check the pictures of the meter/MSP/label. It seems to be 200A.

Greenbook Manual Online
Here is a page from the PGE greenbook with the link above.
Basically, as long as you follow these rules you can connect your new conduit to the existing service panel that is within 36" (10' vertical measurement shown in light and dark hatch above) of the gas riser as long as the panel itself is 12" (horizontally up to 10' elevation shown in light hatch) from the Gas service facility. So as long as you are 36" (straight line radius shown in grey circle area) clear of the gas vent opening, and the metal of the gas service is 18" horizontally from the service panel you could connect new conduit to the existing panel as long as your conduit that did enter the existing service panel had no other joints or couplings within the light or dark shaded area.
These rules are complicated and ever-changing, so no surprise it takes experienced professionals to know them all. Tesla is chasing the bottom and they don't necessarily want to work out of their process to give you the system YOU want. They want you to fit into their box, and they sell the system that they want. That is how they give you the lowest price.
No, you can not put anything within 36" of the gas meter vent. You can run uninterrupted conduit through the diagonal hatched areas as long as none of it is within the 36" radius of the shaded area.@Vines - does this part of the new greenbook actually mean you can run a metal conduit through the 36" radiused circle (as long as the ends terminate outside of the 36" radius)?

You are in Luck! It looks like you have the version of the 200A main service panel that has feed through lugs, and you can connect the GW2 directly to them and do whole home backup easily.Thanks to everyone for the replies.

Writers at PG&E need to stop splitting goddamn infinitives. Like if you clean up their sentence it says.
"conduit... can run completely through... the 36-inch radial clearance..."
You are close to correct, the only thing I would add is:I was curious about this, as this might effectively block any conduit for batteries/subpanels between my garage and the meter/main panel, since the gas riser is in between. I think based on the Exception being for subsection 2.4.2.E.3, and not 2.4.2.E itself, if you break out the AND, @Vines is saying it's meant to be:
"A continuous metallic conduit with no couplings or joints can run completely through [the cross hatched area] outside of the 36−inch radial clearance from the gas regulator vent opening." AND
"A continuous metallic conduit with no couplings or joints can terminate/connect [in the cross hatched area] outside of the 36-inch radial clearance from the gas regulator vent opening."
and not
"A continuous metallic conduit with no couplings or joints can run completely through the 36-inch radial clearance from the gas regulator vent opening." AND
"A continuous metallic conduit with no couplings or joints can terminate/connect outside of the 36-inch radial clearance from the gas regulator vent opening."
Which is unfortunate, as my use cases would possibly like to run conduit through that circle, otherwise to not be unsightly, would have to then go up and all the way around a 9' tall picture window....
I would observe that the greenbook illustration is clearly labeled with a ten inch maximum height (in the illustration in post 86 above), further underscoring @holeydonut's point about ambiguity in PG&E documents...(Now corrected in the on-line version of figure 2-38)You are close to correct, the only thing I would add is:
"A continuous metallic conduit with no couplings or joints can run completely through [the cross hatched area] outside of the 36−inch radial clearance from the gas regulator vent opening." AND
"A continuous metallic conduit with no couplings or joints can terminate/connect [in the cross hatched area] outside of the 36-inch radial clearance from the gas regulator vent opening."
The above is true as long as the termination of the new conduit to the existing equipment does not occur within 12" (up to 10') of the gas service facility.
