Backup Generators 1,000–2,000 kW

Above 1 MW, standby power architecture typically shifts from a single genset to a paralleled array of two or more units (often configured N+1). The mechanical/electrical room footprint, fuel storage volume, and combustion-air ventilation become significant building-design constraints. EPA Tier 4 Final is universal at this size for diesel; aftertreatment maintenance is a non-trivial part of the lifecycle cost.
