Centralized microgrid for remote communities and island resorts
A centralized microgrid that brings solar, battery, generator and grid — where a grid exists — onto one bus, for communities the grid does not reach, island resorts and village power stations. Delivered in Thailand, Malaysia, the Maldives and Vanuatu.
Design figures for a system sized to this use case. What a given site actually gets depends on its load shape, the PV and battery sizing and its tariff — the worked examples below show the inputs.
The Challenge
Islands, remote villages, and off-grid resorts run entirely on diesel gensets — costly, polluting, outage-prone, and far from any utility grid.
- Diesel dependence — Off-grid communities and resorts run gensets around the clock — with fuel shipped in constantly.
- High cost + emissions — Diesel power costs several times the grid rate and emits heavy CO₂.
- Unreliable supply — A single genset is a single point of failure — an outage hits both households and the guest experience.
- Fuel logistics risk — Remote islands face fuel shortages, price swings, and handling risk.
- No clean 24/7 option — Communities want reliable green power all day but have no utility grid access.
Solar is primary by day, the battery carries the night, the genset starts only when neither can cover the load, and a grid line joins the same bus where one exists.
Schematic. The size of each source follows the community load; for sites spread across many locations see the decentralized NODEX approach.
