Large substation is visibly connected to transmission lines. New chillers look fully installed on Building 1-3. Since power and cooling is apparently in place, we expect Building 1-3 are operational. Chillers are almost installed on Building 4-6, with construction equipment still around the building.

Chillers look fully installed on Building 4-6. Some chillers on Building 4 and 5 appear to have snow in the fan holes, suggesting they are not operating and other chillers are operating (since warm air would melt the snow). There is still a bit of construction equipment around Building 6 so it may not be quite operational.

Expect Building 4-6 have finished upgrading with new chillers.
