For facilities where a brief power interruption can have serious consequences, selecting the right industrial backup power system is an important operational decision. The new Caterpillar D1250GC listed by Central States Diesel Generators (CSDG# 5141) combines a high-capacity rating with a Caterpillar C32B engine and a package configured for standby power applications.
This 2024 1250 kW diesel generator is new with zero hours. It is listed at $399,900, located in Edinburgh, Indiana, and offered FOB Edinburgh. CSDG owns the inventory it advertises and has other similar industrial generators, including other Caterpillar and C32 units, in stock and ready to ship nationwide. Availability can change, so contact our team to confirm current options.
Caterpillar reputation: established equipment and support
Caterpillar is a long-established manufacturer of heavy equipment and power systems, with a global dealer and service network. For businesses choosing a standby generator, that presence can be an important consideration: access to knowledgeable service providers and parts support can matter throughout a generator’s operating life, not just at purchase.
Reputation alone, however, is not a substitute for checking the details of an individual unit. Buyers should review the generator’s rating, package configuration, warranty documents, site requirements and maintenance plan. For this specific new unit, the listing identifies a CAT five-year standby warranty. Ask us to confirm the warranty terms and applicable coverage documentation for your project.

C32B engine: V12 power for demanding loads
The D1250GC package is driven by a Caterpillar C32B engine. Caterpillar describes the C32B as a V12, four-stroke-cycle industrial diesel in the 32-liter class. For CSDG# 5141, the engine is rated at 1,865 HP at 1,800 RPM.
A large industrial engine like the C32B is designed for the substantial and changing loads common in critical facilities. Caterpillar’s published D1250 GC information describes the package as capable of accepting 100% block load in one step and identifies performance against ISO 8528-5 load-acceptance requirements. Actual performance depends on the installed package, electrical configuration and site conditions. Facility teams should review the product documentation and confirm project-specific transient-response requirements with their engineer and equipment supplier.
D1250GC output and electrical configuration
This C32 generator is listed at 1,250 kW standby and 1,100 kW prime. Its electrical configuration is three-phase, 60 Hz, and 277/480V. The listed package includes a 2,000 Amp main-line circuit breaker and a PMG (permanent magnet generator).
The standby and prime ratings describe different operating duties; they should not be treated as interchangeable. If you are evaluating the set for regular or extended operation, confirm which rating aligns with your intended duty cycle and have the project team check all applicable conditions, including voltage, load profile and site requirements.
The unit is also listed as EPA Tier 2 and the generator package is UL 2200 listed. These details can help guide project review, but the applicable emissions and electrical requirements should always be verified for the installation location and use case.
A packaged solution for critical facilities
The D1250GC is intended for applications that need substantial standby capacity, including data centers, hospitals, large manufacturing operations, water treatment facilities and other mission-critical sites. The rating and configuration may suit facilities looking to support essential electrical loads during a utility outage. The right generator size depends on the loads to be served, required starting capacity, redundancy plans and expected operating conditions.
CSDG# 5141 includes several features intended to make the package practical for installation planning:
- Sound-attenuated enclosure
- 2,100-gallon UL 142-listed sub-base fuel tank
- Secondary containment and 7-gallon spill containment
- GCCP1.2 digital control panel
- EnerGenius 10 Amp battery charger
- Coolant heater
- PMG permanent magnet generator
- 2,000 Amp main-line circuit breaker
- UL 2200 listed package
The overall listed dimensions are 92 inches wide × 285 inches long × 140 inches high, with a listed weight of 36,288 pounds. Confirm dimensions, access clearances, foundation requirements, lifting arrangements and delivery logistics before scheduling installation.
Startup is not included in the listed offer. Commissioning or startup services should not be assumed to be part of the purchase; discuss those needs with CSDG and your installation provider when planning the project.
