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.
- HV switchgear, GIS, breakers, protection relays — The high-voltage switching, protection, and fault-isolation gear between the substation transformers and the campus's medium-voltage distribution, including gas-insulated (GIS) designs for compact sites.
- MV switchgear, E-houses, power skids — Medium-voltage switchgear packaged into pre-fabricated electrical houses (E-houses) or skids that distribute power across a campus and can be factory-built and shipped as modules.
- 800 V DC architecture & solid-state transformers — An emerging DC power distribution architecture, using 800 V DC in place of the AC busbar and power-shelf approach current racks use, paired with solid-state transformers (SSTs) that could replace multiple stages of conventional AC transformation.
