Pfizer Asia Pacific Pte Ltd

Fuel and Electricity Saving

Pfizer total energy cost (Electricity & Natural Gas) is reduced by ~US$587K/yr due to:

Better fuel utilization and improve plant energy efficiency (achieved ~ 83% efficiency with heat rate of 12.9 mmBtu/MW @ 4.6 MWh output )Reduce electricity consumption due to absorption chilling

Challenges

Rigorous regulatory requirements by regulatory bodies e.g.

New power meters installationOnline metering data and status of breaker to EMA every 30 secContracted capacity subject to Capped or Summation scheme requirementNew interlock and inter-tripping requirement

Fully utilize all the heat energy to be cost effectiveExpertise to operate and maintain the system (partner with Tuas Power Ltd)Gas Supply Reliability
