NEW CUMMINS C3000D6E GENERATOR SETS

3 MW Cummins Generators for Data Centers & Critical Power

Incoming Cummins C3000D6E diesel generator sets provide large-scale capacity for data centers, AI infrastructure, industrial facilities and other critical-power projects.

10 Units | 30 MW Aggregate Standby Capacity | Incoming Fall 2027

Nationwide project support for data center and critical-power applications.

COMPREHENSIVE DATA CENTER SOLUTIONS

Large-Scale Generator Capacity for Data Center Projects

CI Group has 10 new Cummins C3000D6E QSK95-G9 diesel generator sets incoming for Fall 2027. Available for evaluation individually or as part of a multi-unit project, the equipment represents up to 30 MW of aggregate standby-rated generator capacity.

For data centers and other critical-power facilities, generator selection should be coordinated with required load, operating profile, redundancy, voltage, electrical architecture and project schedule.

Each C3000D6E is published by Cummins at:

Final project capacity should be based on the rating applicable to the intended operating profile.

Large Generator Capacity for Demanding Critical-Power Applications

The C3000D6E can be evaluated for projects requiring large-scale standby or data center generator capacity, including:

AI and GPU data centers
New data center construction
Data center expansions
Colocation facilities
Cloud and hyperscale infrastructure
Industrial facilities
Large commercial campuses
Critical infrastructure
Multi-generator backup-power projects

Cummins specifically publishes a Data Center Continuous rating of 2750 kW for the C3000D6E, making that rating particularly relevant when engineering teams evaluate the unit for data-center applications.

Planning a Multi-Unit Generator Project?

Scale Capacity Across Multiple 3 MW Generator Sets

Large data centers and critical facilities often require multiple generator sets to support facility load, redundancy and future expansion.

Multi-unit planning should consider required capacity, redundancy objectives, electrical blocks, phased expansion, maintenance requirements and the generator/switchgear architecture.

Required facility load
Redundancy objectives
Phased data center expansion
Multiple electrical blocks
Maintenance requirements
Planned future capacity
Generator and switchgear architecture

For projects using multiple C3000D6E units, generator controls, paralleling equipment, switchgear, transfer equipment and distribution need to be engineered around the intended operating sequence.

Coordinate Generator Sourcing With the Project Schedule

Generator procurement needs to align with the broader data center construction or expansion schedule. Equipment selection may need to be coordinated with electrical engineering, permitting, fuel-system design, site preparation, switchgear, transfer equipment, freight, rigging and commissioning.

Identifying suitable equipment early allows engineering and construction teams to evaluate the proposed generators as part of the complete electrical design.

Generator Capacity Is Only Part of the Data Center Power System

Coordinate Generators With the Complete Critical-Power Infrastructure

A data center generator does not operate independently from the UPS systems and electrical distribution supporting the facility.

Large critical-power projects may also need to coordinate:

UPS Systems

Provide immediate support to protected loads and bridge the transition between normal and alternate power sources.

Automatic Transfer Switches

Coordinate the transfer of designated loads between normal and alternate electrical sources.

Data Center Power Infrastructure

Plan UPS capacity, generators, redundancy, temporary power and other critical-power requirements together.

Planning Generator Capacity for AI & GPU Infrastructure

Supporting High-Density Data Center Expansion

AI and GPU deployments can materially increase a facility’s electrical load, making existing generator, UPS and distribution capacity important parts of expansion planning.

Before adding significant computing capacity, project teams should review:

Existing and planned critical load
Available generator capacity
UPS capacity and battery runtime
Redundancy requirements
Transfer and distribution equipment
Cooling infrastructure
Planned growth

For additional planning guidance

What to Confirm for a 3 MW Generator Project

Before selecting generator equipment, establish:

Required standby, prime or data center continuous capacity
Number of generator sets required
Required voltage
Phase and frequency
Facility load
Redundancy requirements
Fuel and runtime requirements
Emissions and permitting requirements
Generator placement
Enclosure requirements
Fuel-tank configuration
Switchgear and paralleling requirements
Automatic transfer equipment
Generator-to-UPS coordination
Installation schedule
Delivery and rigging requirements
