Ratings definition (ISO-8528)

ESP - Emergency Standby Power:

It is the maximum power available during a variable electrical power sequence, under the stated

operating conditions, for which a generating set is capable of delivering in the event of a utility power

outage or under test conditions for up to 200 h of operation per year with the maintenance intervals

and procedures being carried out as prescribed by the manufacturers. The permissible average power

output over 24 h of operation shall not exceed 70 % of the ESP.

PRP - Prime Power:

It is defined as being the maximum power which a generating set is capable of delivering continuously

whilst supplying a variable electrical load when operated for an unlimited number of hours per year under

the agreed operating conditions with the maintenance intervals and procedures being carried out as

prescribed by the manufacturer. The permissible average power output over 24 h of operation shall not

exceed 70 % of the prime power.
