Optimizing Energy Efficiency in TerminalsOptimizing Energy Efficiency in TerminalsPresentation OverviewPresentation Overview
• Common Energy Efficiency Problems Found• Common Areas for Efficiency Improvements• Energy Sources and Emissions• Utilization of an Energy Management Program
to Reduce Energy Cost and Emissions
Common Energy Efficiency Problems FoundCommon Energy Efficiency Problems Found
• Use of Low Efficiency Equipment (low initial cost instead of life cycle cost including energy)
• Operational practices: Equipment not operated in it most efficient Range
• Leaving Equipment operating when not needed (HVAC, Lights, Portable Gen sets)
• No Energy Management Program• Management and technical person not understanding
Electrical Rate Structure/cost
Common Areas For SavingsCommon Areas For Savings
Use High Efficiency Equipment Motors (Premium Motors VS Rewind Motors) Lighting (Upgrade T12 to T8, LED, CFL, HPS) HVAC Transformers Use Energy Star Equipment as a minimum Reefer Containers Federal, State, Utility Incentive/rebate

Common Areas For SavingsCommon Areas For Savings
Properly Size Equipment: Understand Requirements Compressed Air Systems Transformers HVAC Lighting Reefer Containers Diesel Engines-Generators
Size to operate at equipment peak efficiency while meeting normal requirements
Utilize Transformers That Meet EPACT 2005
Energy Sources and EmissionsEnergy Sources and EmissionsElectricity: Understanding Rate Structures and Emissions
Electrical Rate Schedule, numerous factors kWh Charge Fuel Surcharge Demand Charge Delivery Feed Power Factor Penalties (KVAR Charges) Ratcheting Charges
Changing Rate Plans can save money Changing When Energy is Used can save money
Understand Usage and Select Optimal Plan
Energy Sources and EmissionsEnergy Sources and Emissions
Engine and Fuels: Diesel/ Natural Gas Efficiency (kg of fuel/kWh and grams of emissions/
kWh) depends on Engine load. Emissions Produced is fuel dependent
Shore Power (Cold Ironing) Average of 6.39% increase in energy usage due to
losses between plant and vessel Emissions may be greater than vessel emissions
depending on plant efficiency and type
Emissions Vary With Source
Vessel Load 570 kWShore Load at Generation Point 606 kW (based on transmission loss 6.39%)*Emission data was obtained from eGrid 2007, for database year 2005.
*Transmission loss obtained from World Development Indicators Database. Latest Data is from 2004.
IMO MEPC Circ 683 (Guidance for Development of SEEMP) ISO 14064 Reduce Energy Consumption and Emission Increase Green Image Energy Conservation can be most cost effective investment
Utilization of an Energy Management ProgramUtilization of an Energy Management Program
Corporate EM Plan and Policies Identify Short- and Long-Term Goals and Strategies Conduct Audits and Baseline energy and Emission Analyze Audit Findings Calculate Life Cycle Costs and
Set Priorities Implement Plan Establish Metrics to Measure Improvement By (per unit efficeincy) Training Review Results and Fine-Tune
