Industrial Hybrid BESS
Micro-Grid BESS
Background & Challenge
An off-grid camp site in Australia relied on two 200kVA diesel generators running continuously to power its essential equipment, including camp lighting, a telecom base station, and general campground electrical systems. This setup presented significant challenges:
-
Low Efficiency
The generators frequently operated below 30% load, a highly inefficient range that leads to excessive fuel consumption.
-
High Costs & Emissions
24/7 operation resulted in disproportionately high fuel costs and unnecessary greenhouse gas emissions.
-
Maintenance Burden
Constant runtime accelerated engine wear, increasing maintenance needs and operational complexity. maintain a 100% reliable power supply.
Solution: A Smarter Hybrid Power System
We implemented a hybrid system centered on a Hexa-250/215-EX Battery Energy Storage System (BESS), integrated with the site's existing diesel generator.
Key Implemented
-
Downsized Generator Use: Shifted from two generators running 24/7 to just one generator operating approximately 9 hours per day.
-
Optimized Generator Performance: The system intelligently starts the generator only to run it at an efficient ~75% load, maximizing fuel efficiency and minimizing runtime.
-
Fully Automated Operation: The BESS automatically controls all generator start/stop cycles, enabling a completely unmanned power plant.
Major Reduction in Fuel & Maintenance
◎ >60% reduction in generator runtime, slashing fuel consumption and costs.
◎ Significantly lower maintenance requirements and extended generator lifespan due to optimized operation.
Uncompromised Reliability
◎ 100% surge load coverage; the hybrid system seamlessly handles high-power demand without interruption.
◎ Zero power interruptions for critical loads, ensuring continuous operation of the telecom base station and camp facilities.
Enhanced Operational Efficiency
◎ Fully automated, unmanned operation reduces the need for on-site staff and manual monitoring.
◎ Significant decrease in emissions, supporting the site's sustainability goals.
Improved Generator Efficiency
◎ The generator now operates at its most efficient load level (~75%), rather than inefficient low-load conditions, ensuring every liter of fuel is used optimally.
