2 Overview Port Energy Initiatives Trends Affecting Port Energy Use Energy Best Practices Microgrids for Effective Energy Management

3 Examples of California Port Energy Initiatives Port of Hueneme - Alternative Maritime Power Program Port of Long Beach - Energy Policy, Electrical Grid Continuity Pilot Study Port of Los Angeles Energy Management Action Plan Port of Oakland - Energy Innovation Initiative Port of San Diego- Energy Roadmap Program

4 Trends Affecting Port Energy Use The ports recognize that their ability to accommodate the projected growth in trade will depend on their ability to address adverse environmental impacts (and, in particular, air quality impacts) that result from such trade. Dr. Geraldine Knatz 4

5 Air Quality & Climate Change Environmental issue that presents the greatest constraint to Port growth AB 32 (CA Global Warming Solutions Act) Reduction in GHG to 1990 levels by % below 1990 levels by 2050 Clean Air Action Plan (POLA & POLB) Reduce DPM by 72%, NOx by 22%, & SOx by 93% below 2005 levels by 2020 Reduce residential cancer risk by 85% by

6 Increasing Energy Demands Reductions in air emissions drive energy trends Alternative Maritime Power AMP: 50% by 2014, 70% by 2017, & 80% by 2020 Accommodation of 10,000+ TEU Ships Port electrification Renewables Operational Growth Terminal Automation 6

7 Example of Projected Energy Demands Port of Los Angeles Harbor Dept 6% Existing POLA Power Footprint 65 MVA 1 Cruise & 7 Cargo terminals (8MW/cargo term avg) + Misc Container Terminals 49% Bulk Terminals 45% AMP MVA 23 Cargo AMP ed Berths at 2.5 MW load/ berth, 60% occupancy with 80% connection requirement 2 Cruise AMP ed berths at 10 MW load/berth, 25% occupancy, 100% connection requirement Container Terminal Automation 90 MVA 6 Container Terminals, average automation load of 15 MW Total Projected Power Demand 190 MVA

8 Trends in Port Energy Demands As the Port becomes more and more automated over the years, the need for high quality electrical distribution is vital. Vahik Haddadian, POLA Sr. Electrical Engineer 8

9 Energy Best Practices Sustainability Reduced GHGs Renewables: Wind, Solar, Wave Energy Efficiency Power Monitoring & Control Systems LED Lighting Energy Efficient Designs Reliability & Security 9

10 Energy Reliability Considerations Increasing renewable generation while reducing system vulnerabilities Redundancy Eliminating single points of failure Modernizing aging infrastructure Physical protection Cyber protection Maintenance procedures 10

11 Microgrids for Port Energy Management Microgrids One or more local power generation assets operating to establish a stable electrical grid without connection to commercial utility power Protect critical infrastructure from power loss Integrate renewable energy sources & distributed generation Sustain operations during prolonged outages Manage installation electrical power & consumption efficiency 11

12 Increasing Complexity Port Microgrid Considerations Islanding from utility Can support closed transition to/from the local utility Operation during long-term outages (natural disasters, cyber attack) Use generation sources to energize a local grid Generator optimization Allows for loads without dedicated backup to be served via the Microgrid Increases redundancy in generation sources through de-coupling Use renewable generation assets during utility outage Provides a grid source for solar and wind inverters Enable market opportunities Peak shaving, demand response, grid services Provides benefit when in grid-tied mode

13 SPIDERS Microgrid DOD / DOE / DHS demonstration for energy security Integration of diesel generation, PV, wind, battery storage, electric vehicles, and other available generation assets Microgrid considerations for prolonged utility outages Robust cyber security measures Reduced carbon bootprint
