Fiji Community Energy Resilience for villages (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 community relied on diesel generators, with fuel costs exceeding $120,000/year. Frequent supply chain disruptions also led to blackouts in addition to the adverse health effects of constant diesel fumes in the air around the village. To be replicated across 20 similar villages across Fiji's islands.

PHNXX Solution:

  • Replace grid and diesel generators with PHNXX modules comprising 210 kW solar PV and 430 kWh battery storage, and an Energy Management System for optimized energy use.
  • Training to be provided to local operators to maintain, operate and monitor the system.
  • Wind-rated up to 135 mph winds, suitable for windy island regions.
  • Cost: $415,000 with up to $200,000 funded by an NGO = $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 unpredictable grid and diesel.
