Community Energy Resilience in Fiji — Remote Village Power (Potential Use Case)

  • Location: Remote villages, Fiji
  • System Details: 210 kW solar PV with 430 kWh battery storage and Energy Management System; wind-rated to 135 mph
  • Impact: $115,000 annual savings, 250 tonnes CO₂ abatement, and 95% reduction in diesel use

Providing sustainable and stable power to communities where grid access is limited or unreliable with heavy diesel generator reliance.

A 250-person remote village relies on diesel generators, with fuel costs exceeding $120,000 per year. Frequent supply chain disruptions cause repeated blackouts, while continuous diesel fumes create health concerns for residents. This scenario models how PHNXX's modular off-grid solar and battery system could be deployed here and replicated across more than 20 similar villages across Fiji.

PHNXX Solution:

  • Deployment of 210 kW solar PV and 430 kWh battery storage, managed by an Energy Management System for optimized energy use
  • Training provided to local operators to maintain and monitor the system.
  • System is wind-rated up to 135 mph, suitable for windy island environments.
  • Cost: $415,000
  • Funding Support: Up to $200,000 from an NGO, reducing net cost to $215,000

Impact:

  • Carbon Abatement: 250 tonnes CO2 per year
  • Annual savings: $115,000 (95% reduction in fuel costs).
  • Payback period: ~1.7 years (partially funded through NGO energy transition grants).
  • 10-year cost savings: ~$1.35 million.
  • Improved energy security: No reliance on unstable grids and diesel supply.
