Parallel Conductors

I'm thinking this is similar to municipalities that own and maintain their own electrical distribution; this sounds similar to how the City of Austin operates and a few other cities (San Marcos, etc). I have worked on only a handful of projects there, but my experience with that is similar to if working with different departments within the City, where everything on the line side of the service entrance disconnect was required to meet Austin Energy's requirements, but everything else was inspected and required to meet the typical building permit requirements. All of this to say that typically the Utility can be an AHJ up to a certain point of the project, but I know we're in a bubble down here in Texas.

I think what you area saying is supply side of service disconnecting means basically isn't subject to NEC inspection but rather is controlled by POCO.

Kind of have same thing here in some cases but typically POCO rules stop at the metering equipment and NEC applies after that point.

What type of raceway? You could probably fit three sets (12-#4/0's) in a 4". That would give you 430.5 amps.

205 amps * 3 = 615 * 70% = 430.5 amps

My Raceway is PVC 40 4inch.

Since you have already purchased #4/0, 3 sets in the one 4" PVC with a single EGC should work.

Yes sir; you said it much more concisely than my novel.

Not a bubble in Texas a bubble in the greater Austin area. With your purple phase conductors and screwed up color code different from the rest of the world!!

Well I technically didn't say I was from Austin, despite growing up close by, only designed a few projects there and I agree with you; San Antonio's the same way too; it's about the only time I get to use the word purple at work.
