Introduction
Jozi Power Limited owns, operates and maintains a fleet of containerised 500kW, 1MW and 2MW diesel
generator sets. Our clients are mines and other large industrial consumers in Africa. The Jozi Power
fleet comprises standard flexible modules that can be used in various power station applications.
Power Modules
The Jozi Power gensets are each built into standard shipping containers. The containers have been fitted
with air intake and outlet louvres and filters that are specifically designed to protect the engine in dusty
environments. Each genset container is effectively a self-contained mobile power station, as it includes the
diesel engine, alternator, cooling system, 1000 litre fuel tank, silencers, flexible control system, air filters,
fuel filters, water-in-fuel detectors and motorised synchronising circuit breaker. All gensets can be controlled
and operated either locally on the local control panel (accessible from outside each genset container) or
remotely via a central control panel with full alarm monitoring capabilities. All genset packages have the
option to be either refuelled locally or connected to a bulk fuel supply and refuelled by an onboard
automatic fuel control system.
Transformer Modules
Jozi Power rents out transformers on their own or they are used as part of our power stations.
Transformer type 1: 400V step-up to 525V, 660V or 1000V, 1250kVA
Transformer type 2: 400V step-up to 6.6kV or 11kV (Selectable), 3150kVA
Transformer type 3: 11kV step-down to 6.6kV or step-up to 22kV or 33kV (Selectable), 5000kVA
Flexible Applications
The flexibility of the Jozi Power package is mostly defined by its state-of-the art control system.
The control package allows the gensets to:
• Run as single units or in groups
• Synchronise automatically when safe to do so
• Be used in standby applications to start automatically when the grid/alternative power source fails
• Run in parallel with the grid/alternative power source
• Accept high loads in a short period of time with rapid multi-engine synchronisation
Independent Power Generation
& Power Station Rental
Note all transformers can be used in step-down applications if required. Types 1 & 2 include output circuit breakers.
The transformer rental fleet are all low-profile hermetically sealed units.

Application
Typical Applications
The Jozi Power gensets are designed to work as single units, but the package really comes to its own
when deployed in groups to provide power in the 3MW-20MW range.
