Above 2 MW, generator selection is driven by paralleling architecture, medium-voltage tie-in, and aftertreatment management. Mission-critical sites (Tier-III/IV data centers, large hospitals) typically deploy paralleled MV gensets with dedicated paralleling switchgear, sub-base or above-ground bulk fuel storage, and SCR/DPF aftertreatment serviced by the OEM service network.
