Southern Cross Energy North (SCEN)
At our Southern Cross Energy North system in Western Australia, TransAlta partnered with BHP Nickel West to respond to a significant change in customer load while maintaining system reliability and cost efficiency.
By enabling grid-forming capability on the existing battery energy storage system, TransAlta created the ability for the isolated power system to operate on 100% renewable generation during periods of sufficient solar production.
This solution:
- Reduced fuel consumption and operating costs
- Maintained voltage and frequency stability in an off-grid environment
- Improved overall system resilience
- Demonstrated flexible integration of solar, battery storage and existing generation
The project reflects TransAlta’s ability to adapt infrastructure to changing customer requirements while maintaining safe, reliable operations.
