What are ratings?
• Approved methods of applying gensets
• Gensets with different ratings are not necessarily
different gensets
• Ratings are trade-offs between:
– Run-hours
– Average load (Load Factor)
– Max power available

ISO8528-1
• ISO = International Standards Organization
• Developed to provide consistency across
manufacturers and industries
• Defines 4 ratings:
– Continuous Power (COP)
– Prime Power (PRP)
– Limited-Time Running Power (LTP)
– Emergency Standby Power (ESP)
• Manufacturers usually use different specifications

Ratings: Common Approaches
• Designing for worst-case scenarios is the norm
– Max possible load
– Worst possible ambient conditions
• Doesn’t reflect real world operation
• Under-loading concerns
• Doesn’t provide optimal value

Uptime Requirements
• Tier Standards:
“Engine generators for Tier III and IV sites shall not have a limitation
on consecutive hours of operation when loaded to ‘N’ demand.”
(Topology paper section 2.5.2)
• Key Uptime requirements
– No limitations on consecutive run hours
– No limitations on load factor

Uptime Compliance
• No limitations on consecutive run hours
Caterpillar’s Mission Critical Rating:
“Output available with varying load for the duration of
the interruption of the normal source power. Average
power output is 85% of the standby power rating. Typical
operation is 200 hours per year, with maximum expected
usage of 500 hours per year.”
• Maintenance consequences…

Uptime Compliance
• No limitations on load factor
– Generator set will not see 100% load factor over
extended periods of time.
• Load is vary rarely close to 100% (see Real World data)
• UPS recharge: 10 to 20% of UPS load
• Chillers/CRACs will cycle based on time of day / season
• Caterpillar’s standby and mission critical standby
ratings comply with Tier III and IV requirements

Compliance process
• Project-specific
• Reviewed, validated and signed by an Caterpillar
person recognized by the Uptime
• Highlights compliance with Uptime Tier III and IV
standards
• Allows to optimize the sizing of your Generator Set
