1. SOLAR ENERGY TECHNOLOGY AND SITING STUDY February 2, 2009

2. Introduction Solar energy implementation at the Port: Aligns with Green Port Policy Goals Addresses commitments made in the resolution to establish a framework to reduce greenhouse gas emissions –Including Port’s commitment to City-wide program Contributes to State’s goals under AB 32 Siting Study is one of the efforts of the Port’s Renewable Energy Working Group

3. Renewable Energy And GPP In relation to the Green Port Policy, renewable energy will: Protect the community from harmful environmental impacts of Port operations by generating green power which avoids the emission of climate-changing chemicals Distinguish the Port as a leader in environmental stewardship and compliance by contributing to the State’s greenhouse gas reduction goals

4. Renewable Energy and GPP Promote sustainability by providing long- lasting, sustainable and reliable power through one of several financially-responsible approaches Employ best available technology to avoid or reduce environmental impacts and help stimulate the creation of new technologies Engage and educate the community by providing information, partnerships, and lessons- learned about renewable energy

5. Objectives of the Solar Study Examine current solar technologies Estimate solar capacity within the Harbor District Prioritize capacity by economic potential Provide rough costs according to today’s market

6. Photovoltaic Technology A photovoltaic system takes advantage of the “photoelectric effect” to convert sunlight directly into electricity.

7. Types of PV Technology Roof-mounted

8. Types of PV Technology Thin film

9. Types of PV Technology Ground-mounted fixed tilt

10. Types of PV Technology Ground-mounted tracking

11. Locations

13. Solar Production at POLB Category Potential MW Example of Category/Installation Large Roofs5.0 200,000 sf roof at National Gypsum Category 4 Lands0.3 Ground-mounted system in unused paved areas Category 3 Lands18.5 Car ports at Toyota Car Terminal Category 2 Lands12.2 Ground-mounted solar on undeveloped Mole areas Category 1 Lands19.0 Pier A West (currently under remediation) TOTAL54.9

14. Cost Ground-mounted fixed = $5.5M to $7M per MW Roof-mounted (assumes existing structural capacity) = $6M to $8M per MW Pole-mounted tracking = $6.5M to $11M per MW Less More

15. Limitations Tidelands Trust and Coastal Act Structural integrity of buildings Lease durations Physical, such as shading or obstructing Cost-effectiveness

16. Conclusions Significant potential for solar development in Port lands Several types of technology may apply Feasibility evaluations must include building life-span, structural concerns, future development of lands Highest Port land use must be considered

17. Next Steps Greenhouse Gas Emission Reduction Program AB 32 Compliance Strategy Project Feasibility Evaluations –Tenant Renewable Energy Partnership –Capital Project Development Technology Evaluation, Advancement, and Education Integration into City’s GHG reduction program
