Madagascar site power: paralleling, fuel burn and backup sizing

Site power in Madagascar runs mainly on diesel sets, the rainy season runs from November to April, and peak load often coincides with concreting, welding and dewatering, so capacity and paralleling must be fixed when quoting.

For paralleling, check speed droop and voltage droop; mismatched settings leave one set at full load and the other light, and the loaded one fails first.

Fuel deviation usually comes from running light: below 40% load a set carbonises and burns more per kWh, while 60-80% is the economical band.

Where the grid exists but is unstable, use parallel or automatic transfer switching that picks up load within ten seconds, so curing and dewatering continue. When applying this in Madagascar, have the local agent review it before it goes into the offer.
