An automated emergency power supply system (EPSS) and testing solution that records generator load values and engine exhaust temperature values to evaluate whether an EPSS test satisfies legislated test criteria. The EPSS test is carried out under software control, which initiates a test by instructing an automatic transfer switch (ATS) to change its status to a test status, causing the essential loads to be powered by a generator instead of a main utility power source.
