Indonesia PLN Multi-Site Power — 117×1000kW Container Gensets
Indonesia — 117×1000kW Cummins Container Gensets across 6 Sites
Project Overview
Indonesia's national utility PLN (PT Perusahaan Listrik Negara) needed to stabilise electricity supply across six sites spanning the archipelago's most diverse operating conditions — from coastal beaches exposed to heavy salt spray, to humid inland rainforest and dusty industrial districts. A scattered geography of islands, weak local grids, and frequent voltage fluctuation meant a single off-the-shelf design would not work.
H&C supplied 117 containerized 1000kW Cummins generator sets, each built around a CCEC (Chongqing Cummins) KTA50-G3 engine, and customized the unit count, operating mode, and daily duty for every site. The fleet delivers emergency standby, peak-shaving, and prime power across the six locations.
Challenge & Requirements
Scattered, Weak Grids — Indonesia's island geography leaves many regions on thin, unreliable local grids with frequent outages and voltage fluctuation — demanding site-specific backup and prime-power strategies.
Harsh Coastal & Inland Climate — Coastal salt spray and strong sea winds, combined with hot, humid, dusty inland conditions, required multi-level anti-salt-spray, anti-moisture, and anti-dust protection.
Three Operating Modes — Each site had to switch flexibly between emergency standby, peak shaving, and prime power — all within a single containerized design meeting Indonesia's SNI certification.
Technical Specifications
| Parameter | Specification |
|---|---|
| Generator Model | HC-CC1250/S × 117 (Containerized) |
| Rated Power | 117,000 kW (117 MW) Total — 1,000 kW per Unit |
| Engine | CCEC (Chongqing Cummins) KTA50-G3 |
| Enclosure | Containerized — Silent, Outdoor-Deployable |
| Protection | Anti-Salt-Spray / Anti-Moisture / Anti-Dust |
| Operating Modes | Emergency Standby / Peak Shaving / Prime Power |
| Compliance | SNI, ISO 8528-5 |
Solution & Implementation
H&C configured the fleet with a “one site, one solution” approach, tailoring unit count, operating mode, and run-time duty to each location's load profile. The integrated containerized silent design requires no dedicated machine room and can be deployed directly outdoors, enabling fast commissioning and low operating cost.
Every unit passed full factory acceptance testing (FAT), anti-corrosion packing, and export documentation before shipment. Multi-level anti-salt-spray, anti-moisture, and anti-dust protection adapts each unit to Indonesia's high-temperature, high-humidity climate, with full SNI certification for the local market.
H&C supported installation guidance, commissioning, and operator training across the six sites, backed by 7×24-hour remote technical support and local service capability to keep the fleet running reliably over the long term.

Project Results
All 117 units were delivered and deployed across the six sites, giving PLN a modular container power station capability that spans remote prime-power regions, urban peak-shaving hubs, and island standby sites.
The project demonstrates H&C's ability to scale a single engine platform into a customized, site-by-site fleet for a national utility — strengthening our credentials in large, multi-site grid-support deployments across Southeast Asia.
