MICROGRID

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.
Centralized microgrid — every source meets on one bus

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.

Centralized village and resort microgrid architectureSolar is the primary source by day and a LiFePO4 battery carries the night; both connect to the DC side of a central PCS. A diesel genset and, where one exists, a grid line tap the same common AC bus. A microgrid controller dispatches all of them and monitors remotely, supplying homes, a clinic, a school and the resort around the clock.Solar Rooftopprimary by dayBatteryCarries the nightCentral PCSone central plantGridwhere a line existsDiesel gensetbackup onlyVillage & resort loadshomes · clinic · school · resortMicrogrid controllerdispatch + remote monitoringDCCommon AC busAC1DC→ACEvery source meets one bus, orchestrated from one placeDCAC

Schematic. The size of each source follows the community load; for sites spread across many locations see the decentralized NODEX approach.
