Federated States of Micronesia ARISE Renewable Energy & Solar Microgrid Expansion

In early 2024, the government of the Federated States of Micronesia (FSM) officially launched the ARISE project (Access and Renewable Increase for Sustainable Energy), funded by the World Bank. This initiative aims to provide safe, reliable, and sustainable electricity to remote island communities across Chuuk State and other regions through the construction of solar microgrid systems, benefiting over 3,000 residents.

As one of the states with the lowest electrification rates in the Pacific region, Chuuk State had only 35% electricity coverage. Local communities had long relied on expensive diesel generators for power, which not only incurred high operational costs but also suffered from unstable supply due to fuel transportation constraints. The ARISE project planned to deploy hybrid microgrid systems in towns including Satowan, Udot, and Eot, integrating Solar PV systems, diesel backup generators, and Battery Energy Storage Systems (BESS).

The project EPC contractor faced multiple challenges during cable selection. The Pacific island environment features high salt spray corrosion, intense ultraviolet radiation, high humidity, and frequent typhoons, imposing stringent requirements on cable weather resistance, mechanical strength, and long-term reliability. Additionally, the project needed to comply with Australian/New Zealand electrical standards (AS/NZS standards) to align with the technical specifications of international funding agencies.

Customer Pain Issues: Dual Dilemmas of Supply Chain and Certification

Through preliminary discussions with the project team, we identified the following core pain points:

Certification Barriers: The project required all power cables to possess SAA certification (Standards Australia Approval) and comply with AS/NZS 5000.1 standards. However, most Chinese suppliers at that time could only provide national standard or American standard products, lacking compliance certifications for the Oceania market. This left the project facing lengthy certification application cycles and uncertain approval outcomes.

Delivery Timeline Pressure: As a government-led infrastructure project, ARISE had strict construction milestones. Due to the remote island locations and extended logistics chains, any delivery delays would cause site work stoppages and generate high standby costs.

Environmental Adaptability Concerns: The customer worried whether standard cables could operate stably long-term in tropical marine climates. Underground sections needed to resist soil corrosion and groundwater infiltration, while overhead sections had to withstand intense UV radiation and salt spray erosion.

System Integration Complexity: The microgrid involved multi-level connections between PV array DC sides, battery storage units, Power Conversion Systems (PCS), and low-voltage distribution cabinets, requiring various cable specifications to work in coordination. The supplier's technical support capability for selection guidance became critically important.

Solution: Comprehensive AS/NZS Standard Cable Custom Supply

Based on these requirements, Dongguan GERITEL Electrical Co., Ltd., as a professional cable manufacturer with SAA certification and AS/NZS 5000.1 standard production qualifications, provided a systematic cable solution for this project.

PV DC Side: Solar DC Cable (EN 50618 / AS Compatible)

For DC side connections in the photovoltaic generation system, we supplied photovoltaic-specific DC cables compliant with EN 50618 standards while meeting AS/NZS compatibility requirements. These cables feature tinned copper conductors and double-layer cross-linked polyethylene (XLPE) insulation, delivering excellent UV and ozone resistance. Conductor cross-sections range from 4mm² to 35mm², accommodating different current carrying needs from string connections to combiner boxes.

BESS Core Connections: 70mm² Orange Circular Cable 0.6/1kV (Featured Product)

For internal BESS connections and PCS interfacing, the 70mm² Orange Circular Cable 0.6/1kV played a crucial role. This cable is strictly manufactured according to AS/NZS 5000.1 standards, with a rated voltage of 0.6/1kV. It employs annealed stranded copper conductors (Class 2 copper conductors per AS/NZS 1125), X-90 XLPE insulation layer, and 5V-90 orange PVC outer sheath.

Product Selection Advantages:

High Current Carrying Capacity: The 70mm² cross-section can continuously carry approximately 200A (air installation), meeting high-power energy transmission requirements between battery clusters.

Orange Identification System: The prominent orange outer sheath complies with Oceania power industry identification standards, enabling site personnel to quickly recognize medium-voltage/power cables and reducing misconnection risks.

Dual Insulation Protection: The XLPE insulation layer features 90°C long-term temperature rating and 250°C short-circuit withstand temperature, ensuring thermal stability during battery charge/discharge cycles.

Full Environmental Adaptability: Passes the 14-day 85°C water immersion insulation resistance test per AS/NZS 5000.1 (≥0.1 MΩ/km), allowing direct burial in moist soil environments.

The project utilized approximately 8,500 meters of 70mm² Orange Circular Cable 0.6/1kV for battery cluster bus connections, DC side connections from battery clusters to PCS (Power Conversion System), and AC output terminals from PCS to low-voltage distribution cabinets.

Building Distribution and Equipment Connections: Building Cable Series

For internal building distribution needs in control rooms and distribution facilities, we provided the Building Cable series, including:

10mm² Orange Circular Cable: For main incoming lines to distribution cabinets and branch distribution circuits

6mm² Orange Circular Cable: For lighting and small equipment power supply

4mm² Orange Circular Cable: For socket circuits and grounding protection systems

These cables employ the same material system as the 70mm² Orange Circular Cable, ensuring compatibility across the entire project electrical system and maintenance convenience.

Equipment Internal and Flexible Wiring: Multicore Flexible Cable

For signal transmission and power connections inside PCS, monitoring equipment, and Battery Management Systems (BMS), we supplied Multicore Flexible Cable featuring IEC 60228 Class 5 fine-stranded copper construction. This delivers excellent bending performance (minimum bending radius of 15 times cable diameter for mobile installation), facilitating wiring in compact equipment spaces. Specifications range from 2.5mm² to 16mm², with core configurations from 4-core to 24-core, meeting different control circuit signal isolation requirements.
