UPS Systems Enhance Reliability of Indonesia’s Rail Network

Salicru has expanded its presence in Southeast Asia’s rail sector by supplying uninterruptible power supply (UPS) systems for Indonesia’s national railway operator, PT Kereta Api Indonesia (PT KAI). The project strengthens the reliability of critical rail infrastructure across key operational regions, supporting both passenger and freight transport.

Supporting a High-Demand Rail Network
Indonesia’s railway network plays a central role in mobility across the archipelago, particularly on the island of Java, where a large share of the population and economic activity is concentrated. Ensuring continuous power supply is essential for maintaining signalling, telecommunications, and control systems that underpin safe and efficient rail operations.

The deployment was carried out in collaboration with PT BINA SERVICES, enabling adaptation of the UPS solutions to local operational requirements and environmental conditions.

Modernisation and System Upgrades
The project included both new installations and the replacement of legacy UPS systems at major railway hubs. On Java, deployments covered several operational divisions, including Jakarta, Bandung, Cirebon, and Central Java regions, where high passenger volumes require robust infrastructure.

UPS systems such as the SLC CUBE-4 and TWIN RT2 were installed to provide electrical continuity, ensuring uninterrupted operation of critical systems even during power disturbances.

Expanding Reliability in Freight and Regional Networks
On the island of Sumatra, which plays a key role in freight transport and regional connectivity, a combination of new systems and upgrades was implemented. Solutions including SLC CUBE 3+ and SLC CUBE-4 were deployed to enhance infrastructure resilience in demanding operating environments.

These systems support stable operation across distributed rail networks, where power reliability is critical for maintaining service continuity.

Integration with Urban Transit Systems
In addition to mainline rail infrastructure, Salicru’s UPS systems have been installed in light rail transit (LRT) networks in metropolitan areas such as Jakarta and Palembang. These systems support high-frequency urban transport operations, where consistent power supply is required to manage passenger flows and maintain service reliability.

Extending to Critical Infrastructure and Data Systems
The deployment also includes applications beyond rail transport, with SLC ADAPT2 solutions used in aviation infrastructure and data centers managing critical systems. These installations support scalable and high-availability power solutions, contributing to the broader digital supply chain that underpins transport operations.

Relevance for Railway Infrastructure
Reliable power systems are a fundamental component of modern rail networks, ensuring the continuous operation of signalling and communication systems. UPS technologies help mitigate the impact of power disruptions, reducing the risk of service interruptions and improving operational safety.

The project reflects ongoing investment in infrastructure resilience across Southeast Asia, where growing transport demand requires stable and efficient railway systems supported by robust energy and digital infrastructure.
