• The customer (TransAlta) wanted to reduce dependency on gas/diesel generation.
• The customer required a stable and reliable microgrid control system to facilitate the delivery of renewable energy to its large industrial customers while ensuring grid stability and reliability. 
• The end user (BHP) sought to minimize or reduce Scope 2 emissions associated with the nickel plant. 
• The bench testing process was hindered by the lack of access to generating equipment. 
• Request for a secure, market proven and tested solution that meets specific customer needs.

• Two hybrid generation plants were situated 90 kilometers apart both feeding the mine: One near the village of Leinster, the other subproject near Mount Keith.
  
• Siemens provided two secondary control microgrid solutions that interface with the tertiary control system, transmission grid, and the primary control equipment at Mt Keith (141.2 MW) and Leinster (80.9 MW). 

Mt Keith  

• 25.2 MW solar pv plant
• 1x40 MW LM6000 gas turbine
• 1x18 MW TM2500 gas turbine
• 5x11.2 MW Sulzer diesel generator 

   
Leinster 

• 10.5 MW solar pv plant
• 10 MW / 4.5 MWH BESS 
• 1x40 MW LM6000 gas turbine
• 2x6 MW Wärtsilä diesel generator 
• 4x2.1 MW EMD diesel generator

• Our scope includes the supply of two redundant pairs of A8000 CP-8050 controllers with the microgrid license, configuration, bench testing, FAT and commissioning of the microgrid solution. 
• Siemens and JUWI worked together to advance microgrid technology in this project using Siemens' SICAM Microgrid Controller, enhancing energy efficiency and reliability for mining operations. This collaboration allowed for a combined expertise in driving sustainability within the industry. 
• JUWI was responsible for planning, designing, installing and commissioning of the microgrid controller for the end customer TransAlta, ensuring seamless integration and optimal functioning of the assets.
• The SICAM microgrid controller from Siemens acted as the foundation for JUWI's Hybrid IQ controller, combining advanced technology with extensive industry knowledge.

Solar hybrid climate-friendly energy for one of the fifth largest nickel mines in the world. This project was TransAlta’s first renewable energy project in Australia.
