What the shared parts are
- Large power transformers (345–765 kV) & substations — Grid-scale transformers and switchyards that step transmission voltage down to what a data center campus can use, plus the substation civil works around them.
- MV/LV transformers — Step-down transformers that take medium-voltage distribution down to the low voltage used inside a building, available in pad-mount (outdoor, oil-filled) and dry-type or cast-resin (indoor) designs.
- STATCOM and synchronous condensers — Manufacturers of STATCOMs and synchronous condensers that stabilize grid voltage and provide reactive power support near large loads.
