What the shared parts are
- Floor PDUs, RPPs, static transfer switches, ATS — Floor-mounted power distribution units, remote power panels, and the static and automatic transfer switches that route power between utility, UPS, and generator sources down to the rack level.
- Backup generation: gensets, fuel systems, HVO — Diesel or gas-fired backup generators, their fuel storage and delivery systems, and renewable diesel (HVO) as a lower-emission fuel alternative, providing power when utility and UPS ride-through are not enough.
- Paralleling switchgear & generator controls — Switchgear and control systems that synchronize and combine the output of multiple generators so they can operate as one larger backed-up power source, and manage the transition between utility, UPS, and generator power.
- Reciprocating engines & engine microgrids — Diesel, natural-gas, or dual-fuel reciprocating engines assembled into modular microgrids for onsite or bridge power at a data center site.
