Driving Pulau Ubin’s Renewable Energy Transition with
Vanadium Redox Flow Battery
EDP Renewables APAC is the Asia-Pacific arm of EDP Renewables, a global leader in renewable energy, focused on developing and operating wind, solar, and energy storage projects across the region.
Pulau Ubin, a remote island in Singapore, has historically relied heavily on diesel generators for electricity, resulting in high fuel costs and significant carbon emissions.
As part of Southeast Asia’s first smart microgrid project, VFlowTech was selected to deploy its Vanadium Redox Flow Battery (VRFB) system alongside a solar roof installation, aiming to reduce diesel dependence and transition the main village to cleaner energy.
At A Glance
Product: 2 x 100 kW/500 kWh (Forming a 200kW/1,000kWh system)
Location: Singapore
Applications: Grid reliability, Smart microgrid, Reliable power
Scope of Services: Battery Installation, BMS & EMS Integration
Solution
Based on the given continuous load of 50kW for 20 hours or 1MWh requirement connected to a smart microgrid, VFlowTech deployed a 200kW/1MWh VRFB system, comprising:
- 2 × PowerCube 100-500 units (100kW/500kWh each) in 40-feet containers
- Seamless integration with 328kWp solar PV array
- Turnkey system including battery management system (BMS) and power conversion (PCS)
The system is further complemented by an intelligent control and monitoring solution developed in-house for managing the solution with advanced functionalities.
