When disasters occur, whether from severe storms, bushfires, floods, or unexpected grid failures, reliable power becomes essential. It keeps communications running, supports emergency teams in the field, and allows communities to access critical services.
Across Australia, emergency services, councils, utilities, and rapid-response organisations are seeking flexible, efficient power solutions. Hybrid diesel–battery deployable power systems combine the proven reliability of diesel generators with the stable, quiet output of high-capacity batteries and inverters, all integrated into a mobile platform. These systems provide dependable off-grid power that can be deployed quickly, operate in challenging conditions, and support a wide range of emergency and community needs.
This article explores how hybrid deployable power systems strengthen disaster response, the areas where they are most useful, and how solutions like the Buffalo SPS Hybrid Power Trailer contribute to community resilience.
Extreme weather events are becoming more frequent and disruptive. Communities and emergency services often face multiple power challenges, including:
In these situations, emergency personnel need power systems that are:
Hybrid diesel–battery systems, or diesel optimisers, are emerging as one of the most versatile tools to meet these requirements.
Hybrid power systems combine diesel generators with high-output battery–inverters to create a flexible platform capable of supporting a variety of applications, from communications to command posts, temporary housing to cold chain and food preparation.
Key advantages include:
Quiet, low-disturbance operation
When operating on batteries, hybrid systems provide near-silent power, which is useful for night-time operations, evacuation centres, residential emergency zones, and mobile command units. Essential equipment can run without adding unnecessary noise, and when additional power or extended runtime is required, the diesel generator engages automatically to recharge the battery or supply higher loads efficiently.
Fuel efficiency and extended runtime
The battery and inverter manage outgoing loads while the generator:
These efficiencies are particularly beneficial when fuel logistics are disrupted.
Safe and flexible operation
Battery mode allows power delivery in locations where traditional generators may not be suitable. The diesel generator primarily runs during sustained high loads or to recharge the battery, reducing engine wear and ensuring maximum energy extraction from fuel.
Fast deployment and stable output
Hybrid systems are designed for quick setup and reliable operation. They provide:
This capability supports communications networks, refrigeration, lighting, and digital infrastructure during emergencies.
Regulated power for electronics
The inverter provides stable output suitable for radios, satellite systems, networking equipment, medical & diagnostic tools*, and other electronics. Devices that would normally rely on diesel generators benefit from cleaner and more consistent power, reducing the risk of voltage fluctuations or spikes.
Emergency evacuation centres
Hybrid systems reliably support lighting, communications, refrigeration, charging hubs, Wi-Fi, and general-purpose electronics, improving safety and comfort for displaced communities.
Mobile Incident Control Points (ICPs)
Continuous, stable power is essential for laptops, satellite communications, networking equipment, radios, lighting, and drone charging. Hybrid trailers provide dependable power without complex setup, strengthening field command operations.
Field medical stations
Hybrid trailers deliver regulated power suitable for electronics such as lighting, communications equipment, medical & diagnostic tools*, and refrigeration. For devices that would normally be connected to diesel generators, hybrid systems offer cleaner, more stable operation.
Communications and connectivity restoration
Hybrid systems can power mobile repeater towers, portable radio networks, satellite links, internet hubs, Wi-Fi access points, and community charging stations. This ensures responders and residents remain connected when the grid is unavailable.
Community charging and support hubs
These systems provide reliable energy for phones, radios, torches, battery packs, and laptops. Portable power units can operate pop-up charging stations for extended periods, helping communities stay informed during recovery.
The Buffalo SPS Hybrid Power Trailer is designed for rugged, real-world emergency conditions, providing reliable and flexible energy wherever it is needed.
Key features include:
The system can operate solely on battery, solely on diesel, or in hybrid mode, offering full flexibility depending on mission requirements.
Buffalo SPS Hybrid Power Trailers provide emergency responders with:
As climate-driven events continue to challenge Australia’s infrastructure, hybrid deployable systems will become essential assets for councils, emergency services, and critical community operations. Buffalo SPS supports this transition by building systems that help communities stay safe, connected, and resilient.
*Whilst these systems provide safer, more stable power output than conventional diesel generators, they are not intended or specifically certified as a primary power source for life-supporting medical equipment. End users should always assess suitability for critical medical devices.
