Princeton University District Ener gy System 331

• Princeton worked with Carrier Corporation to install and properly control the
first side-by-side application of two 270-kW Microsteam backpressure turbine
generators.
• Princeton collaborated with Icetec to develop the most advanced economic
dispatch system found in any district energy plant. This is a “living” system
that is continually being improved to meet the changing needs of the campus,
the plant operators, and campus administrators. Recently, Princeton and Icetec
have added “real-time carbon emission measurement” to the system.

Employee Safety and Training
• With a total plant staff of 29, the energy plant has averaged fewer than 15 lost
workdays per year for the past 8 years. This represents a rate of 0.21 percent.
• Plant personnel are continuously trained on safe operation and maintenance
practices and are actively involved in continuous improvement of plant safety.
• Princeton conducts an extensive safety and training program that includes
involvement from operating union personnel and the campus Environmental
Health and Safety (EHS) office. A root-cause analysis and written report is
performed following any reportable accident.
• All key stakeholders on campus including EHS, engineering, plant operators,
electric shops, and building maintenance personnel are currently involved in
developing an NFPA-70 Arc Flash safety program.
• The plant safety committee meets on a quarterly schedule to discuss any is-
sues that are raised, ranging from union shop rules or changes to policies,
procedures, or code requirements. Along with the safety committee, Princeton
provides annual training along with frequent toolbox talks that the EHS office
recommends. In order to efficiently communicate to plant personnel on all
shifts, a password-accessible Web site has been created where operating mem-
os and all safety procedures are available from any Web-accessible computer.
Plant safety training programs include
• Emergency action and fire prevention plan
• Right to know survey with MSDS documentation
• Required personal protective equipment
• Respirator protection program for air purifying respirators
• First aid
• Cardiopulmonary resuscitation (CPR)
• Fuel oil spill response
• Response to fire in gas turbine and gas compressor
• Campus utility interruption guidelines
• Blood-borne pathogen exposure control
• Automated external defibrillator (AED) unit operation and emergency
response
