A large remote cattle station in Australia has adopted a renewable microgrid as its primary power source. The project is directly relevant to agricultural water systems because reliable electricity is needed for bore pumps, transfer pumps, livestock water, communications and refrigeration across isolated sites.
Design the water duty before the power system
Remote pumping should be sized from water demand, total dynamic head, seasonal solar resource and motor starting current—not from annual energy alone. Daytime storage tanks can often reduce battery demand by shifting part of the energy storage task from electricity to water.
Plan for service at a remote site
Buyers should require remote alarms, documented controller settings, critical spares and a manual fallback plan. A microgrid is valuable only when technicians can diagnose faults and keep the water supply operating during poor weather or maintenance.
