A diesel generator is the combination of a diesel engine with an electric generator to generate electrical energy. Diesel generating sets are used in places without connection to a power grid, or as emergency power-supply, if the grid fails and are thus ideal for load shedding situations.

Proper sizing of diesel generators is critical to avoid low-load or a shortage of power. Powerstar has a ‘Generator Size Estimate’ tool on our online platform, that utilises the extensive demand data recorded for a specific Power-Star meter, usually installed on an electrical supply, to determine an indicative size for a generator based on actual demand data. The report lists the 50 highest Active Energy (kW) points over the last 12 months applying a 1-minute interval. The indicative generator size is based on these highest values plus 20% to provide for the standard power factor of 0.8 at which a generator runs. In addition, a 10% safety buffer is added.
