Groupes électrogènes Comment assurer un dimensionnement optimal en fonction des critères de l Uptime Institute Loris Buess, Caterpillar 17 Septembre 2014
The generator set shall be rated 2MW continuous Page 2 CATERPILLAR CONFIDENTIAL: YELLOW
Ratings Data Center Genset Usage Complying with Uptime Requirements Page 3 CATERPILLAR CONFIDENTIAL: YELLOW
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 Page 4 CATERPILLAR CONFIDENTIAL: YELLOW
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 Page 5 CATERPILLAR CONFIDENTIAL: YELLOW
ISO vs Caterpillar ISO 8528-1 Ratings Emergency Standby No ISO equivalent No ISO equivalent Limited-Time Running Prime Power Caterpillar Ratings Emergency Standby Standby Mission Critical Standby Load Management Prime Continuous Power Continuous Page 6 CATERPILLAR CONFIDENTIAL: YELLOW

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 Page 11 CATERPILLAR CONFIDENTIAL: YELLOW
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 Page 12 CATERPILLAR CONFIDENTIAL: YELLOW
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 Page 13 CATERPILLAR CONFIDENTIAL: YELLOW
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 Page 14 CATERPILLAR CONFIDENTIAL: YELLOW
