Case Study: Hybrid Backup Power Solution for Construction Crane Using Generator and Battery Energy Storage System (BESS)
Client Overview
A major construction site in Melbourne required reliable power for a tower crane, which was critical for lifting operations. The site demanded a continuous, stable power supply while also aiming to reduce its carbon footprint and operational costs.
Challenge
Traditionally, cranes at construction sites are powered by diesel generators, which provide dependable energy but come with significant noise, fuel consumption, and maintenance requirements. The client wanted a solution that would:
- Reduce generator run hours and fuel usage
- Minimise noise impact for nearby residents
- Lower maintenance frequency and costs
- Maintain a reliable and continuous power supply
Solution: Hybrid Generator and BESS System
GENGEAR designed and implemented a hybrid power solution combining a diesel generator with a Battery Energy Storage System (BESS).
How it worked:
- The generator supplied power during peak demand and charging of the battery.
- The BESS handled fluctuations in power demand and provided energy during idle periods, dramatically reducing generator run time.
- Automatic switching between the generator and BESS ensured the crane had continuous power without interruption.
Benefits Delivered
The hybrid solution delivered measurable benefits for the site:
- Reduced Carbon Footprint – The BESS allowed the generator to run fewer hours, cutting diesel consumption and CO₂ emissions.
- Lower Noise Levels – With the generator operating less frequently, overall site noise was significantly reduced, improving conditions for nearby residents and workers.
- Fuel Efficiency – Diesel use decreased, reducing costs and environmental impact.
- Higher Service Intervals – Reduced generator runtime translated to less wear and tear, extending maintenance intervals and lowering service costs.
- Seamless Reliability – The crane maintained continuous power supply with no disruption to operations, even during generator maintenance or refueling cycles.
Conclusion
By combining a generator with a Battery Energy Storage System, GENGEAR provided a sustainable, cost-effective, and reliable power solution for the construction site. This hybrid approach demonstrates how temporary power solutions can be upgraded to reduce environmental impact while improving operational efficiency.
