A construction site in Singapore has implemented a 500kW/500kWh hybrid energy storage system, successfully achieving off-grid power supply while improving energy efficiency and advancing green transformation. This project sets a new benchmark for energy-saving and carbon reduction in the construction industry.

Core Configuration:

The system consists of 4 units of 125kW PCS (Power Conversion Systems), employing an innovative diesel + battery complementary (hybrid) solution that supports 1C discharge. The 4 PCS units operate in parallel for off-grid applications, forming a stable power output network. Acting as a “smart energy reservoir”, the storage system charges during low-demand periods and discharges precisely during peak demand, continuously powering tower cranes, hoists, welding machines, and rebar bending machines.

Project Highlights and Impact:

Significant Diesel Savings: The hybrid system, combined with diesel generators, reduces diesel consumption by 125,600 liters annually.

Carbon Emission Reduction: Annual CO₂ emissions decrease by 330,328 kg, equivalent to the carbon sequestration of 18,350 mature trees.

Operational Efficiency: The system lowers noise pollution on-site, extends diesel generator lifespan, and improves overall power generation efficiency.

Project Statement:

“The diesel + battery complementary system completely changes the traditional reliance on diesel generators,” said the project lead. “Stable power supply ensures construction progress, while low-carbon transformation aligns with Singapore’s sustainability goals and provides a replicable model for similar projects.”

Conclusion:

This Singapore construction site demonstrates a successful green transformation of off-grid construction power supply, providing a practical reference for the wider adoption of hybrid energy storage systems in global infrastructure projects.
