Many Australian sites still rely on diesel generators to maintain operations during outages or in remote locations. But with fuel prices rising and environmental pressures increasing, businesses are seeking more efficient ways to reduce generator runtime and operating costs.

Integrating a Battery Energy Storage System (BESS) with your existing generator setup is one of the most effective ways to achieve immediate fuel savings, stabilise power quality, and extend generator life—without replacing your current equipment.

Recent industry case studies show just how significant the gains can be. When paired with a well-designed BESS, generators can reduce fuel consumption by up to 84%, cut runtime by 95%, and improve overall fuel efficiency by more than six times. The battery absorbs load fluctuations, handles low-demand periods, and supplies power instantly when required—allowing the generator to run only at its most efficient operating range. This results in quieter operation, reduced emissions, lower maintenance costs, and extended equipment lifespan.

Energa engineers generator-battery hybrid systems tailored to each site’s operational profile, ensuring the battery is correctly sized, safely integrated, and optimised for performance. With 30+ years of industry experience, SAA-accredited installers, and deep knowledge of local regulation and compliance standards, Energa delivers bankable, reliable BESS solutions that support both continuous operation and emergency backup requirements. Whether your energy challenges are driven by remote operations, rising fuel costs, or increasing grid instability, Energa designs systems that deliver measurable operational value from day one.

Ongoing monitoring and maintenance help protect your investment over the long term. Energa provides full lifecycle support—including performance analytics, inverter and battery audits, generator synchronisation checks, and preventative maintenance—to ensure your hybrid solution continues to operate safely and efficiently.
