Optimizing Energy Efficiency in Terminals Presentation 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 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 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 Programs Being Green Improve Corporate Profits

Common 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 Emissions Electricity: 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 kW Shore Load at Generation Point 606 kW (based on transmission loss 6.39%)* Emission data was obtained from eGrid 2007, for database year * Transmission loss obtained from World Development Indicators Database. Latest Data is from 2004.
