Hi Mike, I have a project that I think you would be perfect for.
I have a working design of a containerized datacenter hosting solution for hosting computer servers. These containers take 400 amps of 208V three phase power, and are 8' x 40' standard shipping containers, and ideally are spaced 8 to 10 feet apart in a line.
I need to come up with an efficient way to power a lot of these on a plot of land, such that the PUD can power them consecutively without me having to pay a monsterous up-front cost all at once.
So for example, one option I considered was setting up a line-rate switchbox with ~10-30 mW of power and building from there, and getting investors to fund it; This would allow me to avoid PUD timelines and terminate the line voltage very close to the destinations. But there's a lot of hurdles there. Another option was a lot of little builds spaced around all over, but that has hurdles too.
Much easier would be if I could just build them 1-5 at a time. In an ideal world, I would come directly off a power pole at line rate, go into a transformer sitting on the top of the container (or attached to the back) @ 150 kVA, which then steps down from line rate to 208v. Since ultimately I'm going to be paying for the transformers anyway, I don't mind providing those. However, those transformers may be too heavy or impractical or just straight up not allowed on the container itself.
Another option would be to do the same basic concept, but through buried feeders. I don't have any need to have my power underground, but it may be required by the PUD/code/L&I. This could either go to a transformer on the container, or a padmounted transformer. Ideally we want the 208V runs with those giant feeders to be as short as possible.
Strangely, [url removed, login to view] won't let me submit this job because I'm "almost" out of characters for the description. Almost is apparently just as bad as being out of them... More in comments.
