Generation asset

Jenbacher J420 gas generator

Multi-fuel capable engine designed for operational flexibility across conventional gas supply and renewable biogas pathways.

Nominal electrical output
Approximately 1.4 MW (1,415 kW class)
Electrical efficiency
Typically 42–44% on natural gas (approx. 43.1% on biogas)
Fuels
Natural gas, CNG, LNG (vaporised), biogas / landfill gas and other suitable gas fuels
Thermal (CHP)
Thermal output available in CHP configuration (up to ~1,906 kW)

Network connection

2 MW at 22 kV — already established

The existing connection significantly reduces the time, cost and uncertainty normally associated with securing grid access for a new energy project.

  • Connection capacity: 2 MW at 22 kV already established
  • Synchronising switchgear installed and ready
  • Earthing grid in place
  • Foundation for reconnection and potential expansion subject to Western Power requirements and headroom

Supporting infrastructure

Plant, services and layout

  • Electrical switchgear and control systems associated with the existing generation plant
  • Site services and hardstand areas suitable for additional plant (including containerised BESS modules and fuel storage)
  • Practical layout that allows the existing Jenbacher asset to remain in place while new storage or hybrid equipment is installed
Distribution boards and Jenbacher HMI
Site transformer

Biogas & fuel flexibility

Multi-fuel pathways

The Jenbacher J420 is inherently capable of operating on biogas and other alternative gas fuels.

  • Local or regional biogas offtake
  • CNG / LNG supply arrangements (virtual pipeline or bulk delivery)
  • Hybrid operation alongside future solar or battery assets

Fuel storage recommendations for Reserve Capacity Mechanism (RCM) compliance (including 8-hour runtime buffer requirements) are addressed in the detailed technical material available under NDA.

Development context

The combination of an existing 2 MW network connection, synchronising equipment, earthing grid and multi-fuel generation asset positions the site for standalone BESS, hybrid BESS + gas/biogas generation, and staged capacity expansion. Full details of network capacity, BESS sizing recommendations, Reserve Capacity Mechanism eligibility and financial modelling are in the password-protected Development Potential section.
