The Major Substation is one of the two places the Chinese community wiki names for the elevator extraction: pulling the switches at the administration building and at the main substation starts a three-minute countdown. The publisher's own map tool records 19 supply points here, 5 of them keycard-locked, and places the riverbank paid extraction to the south.
On the detail map: the white ring marks this area; grey blocks are the other named areas; green dots are west-camp insertion points and blue dots east-camp ones; an amber ring is an extraction point; the red diamond is the resident boss. The surfaces are drawn the same way as on the full map — olive ground, blue water, cool grey roads, warm pale buildings, blue-grey crossings. The full Zero Dam map carries the same key and labels every area.
Where It Sits
The substation sits east of the map's centre on the east camp's side, and is the only one of the six areas whose nearest extraction point is the paid one.
Counts and container types: the publisher's own map tool, read October 10, 2026. The nearest extraction point and the nearest camp are read off the same tool's marker positions, which is a comparison of its own coordinates rather than a distance the tool publishes.
Supply Points Recorded Here
The map tool records 19 supply points in this area, across 10 container types, with 5 of them needing a keycard. The map tool files this area's markers under major substation (大变电站).

What the Community Wikis Record
The notes below are those wikis' own: the Chinese community wiki's page for Zero Dam for the value order, the layout notes and the extraction table, and the English community wiki's for the setting and the boss. Where a note below is not on either wiki, the sentence says which source it does come from.
The second elevator switch. The Chinese community wiki records the main substation as one of the two switch points for the elevator extraction, and rates the contact risk of pulling them as very high, because it announces your position to the whole map.
The paid extraction sits south of it. The wiki's extraction table places the riverbank paid extraction south of the main substation: 10,000 哈夫币 buys one slot on the regular tier, with a 30-second wait after paying.
Lab coats and servers. The map tool's record for the substation is the only one on the map where lab coats and servers both appear near the top of the container list, which fits a working control building.

Update Rule
Supply points are added and moved with season patches, and this page tracks what the publisher's map tool and the two community wikis record rather than trying to keep pace with every adjustment. The date at the top records when those were read, not when the game last changed. If the publisher's own material disagrees with anything here, the publisher is correct and this page is out of date.
