Presentation to San Diego Sierra Club Richard Caputo 12 Nov 07 Renewable Energy Parks

2 The Issue Almost all Renewable Resources for the SD Region Are Outside San Diego County, –84% of the total Roof Top Solar Plus Other In-region Sources Make Up Only 16% We Want to Capture Benefits of Renewables for the Residents and Businesses of the SD Region

Renewable Energy Parks3 County of San Diego Interests There are opportunities within the County of San Diego to increase renewables to 50% of the total renewables production by 2030 This would: –Add Jobs in San Diego County –Add a New Tax Base in San Diego County –Exercise Local Control O ver Our Energy Sources – Significantly Reduce Fossil Fuel Dependence and Production of Green House Gases---AB32 –Reduce the Need for Transmission Lines from Outside SD Cty

Renewable Energy Parks4 In-County San Diego Renewables Total Resource Similar to Current San Diego Peak Demand --- About 5000 MW Derived from: –Concentration Solar Plants, ~72% –Wind, ~ 20% –Roof Top PV, ~ 5% by 2020 based on CSI –Biomass/Biogas Plants, 3%

Renewable Energy Parks5 Key Characteristics of Largest San Diego Renewable Resource – Concentrating Solar Power Plant Would Be 5 to 35 MW – Small –Typical Power Plants are 100 to 300 MW 10 to 30 Smaller Solar Plants in San Diego County Are Needed To Equal One Desert Plant of ~300 MW Many Smaller Plants Are a BARRIER to In-County Development –High Transactions Cost for Multiple Sites –Many Sets of Permits, Zoning Changes, Environmental Assessments, etc

Renewable Energy Parks6 Actions To Overcome Barrier Level Playing Field for Many Dispersed Smaller Plants In-County: –Create Dispersed Renewable Energy Parks –Sites Brought to Ready-to-Build Status –Make These Sites Available to Plant Builders When They Sign Contract with SDG&E

Renewable Energy Parks7 Roof Top & Industrial PV Solar Power Park Wind Power Park Solar Power Park Solar Power Park Wind Power Park Solar Power Park Proposed sites for solar and wind Power Parks. Environmental assessments, permits, power lines and water are pre-arranged by San Diego County action

Renewable Energy Parks8 Renewable Energy Park is Similar to Industrial Park Sites Are Prepared and Permitted in Advance. County of San Diego Invests in Site Preparation, Investment Recovered from Property and Sales Taxes on Development of Solar and Wind Generation at the Sites, and Assembly Plants. In-County Jobs with Secondary Economic Boost and Additional Taxes.

Renewable Energy Parks9 Proposed County Action Step 1: Sign MOU with SDG&E –They would agree to buy power from renewable power plant builders using County Energy Parks Step 2: Streamline Multiple Power Plant Approval Process for Renewable Energy Parks on Land Within SD County Step 3: Establish Multiple Renewable Energy Park Sites 3 to 5% of Plant Cost Up-front to Set Up Parks –Similar to creating an industrial park

Renewable Energy Parks10 Step 2: Streamline Multiple Power Plant Approval Process 1. Review county current regulations and internal processes for approving the construction and operation of a 5 to 50 MW renewable energy power plant in the County e.g. zoning changes, permits, reviews, etc. 2. Identify bottle necks that would result if 50 to 150 of these similar power plant applications were made within a short time (~ 1 to 5 years). 3. Identify ways to streamline the process and 'pre- approve' these types of projects of this range of size and types of technology. 4. Implement a program to bring out this streamlining of procedures and approvals for these power plants and to allow their fast-tracking.

11 Step 3: Establish Multiple Site Renewable Energy Parks Authorize an Entity (for-profit, non-profit or SDG&E) to Provide the Following Services: –perform the initial survey studies of East-County power line capabilities and cost of up-grade to carry up to a total of 1500 MW of renewable power distributed over East-County San Diego –Determine the preferred locations for these smaller renewable energy power plants in East-County –Lease or procure these lands –Obtain zoning changes and other permits –Generate Environmental Impact Assessments –Connect to local grid –Put sites into the renewables land bank for later use by power plant contractors when they sign a power purchase agreement with SDG&E

Renewable Energy Parks12 Summary To Establish a More Secure Energy Future for San Diego County That Is: – Based on Renewables –50% of Renewable Power Is Home Grown with Local Jobs Local Taxes –Reduce Need for Long Distance Transmission Lines Create a Renewable Energy Park Throughout East County San Diego Investment Returned to County by taxes paid by new solar power park employees, construction workers and land use taxes

Early Project Questions ? What Are the Up-Front Costs for a Typical Site? What Is the Current Process for Site Approval –How Could It Be Streamlined by the County –By Other Agencies Normally Involved Of the ~ 4500 MW Resource, How Much Is Close to Existing Transmission Lines Would Ranchers Be Willing to Lease Land for Power How Much Power Can the East County Grid Carry to San Diego Without Modification How Much Can This Be Increased by New Technology Wires That Appear the Same What Would Be the Next Increment in Power with Wires That Look Different – how different? 14

Other Early Project Questions ? Renewable Energy Parks15

Approaches for Joint Project Joint Task Force –Several members of both organizations –One task leader chosen by task force Other Approach ? How To Direct Mentored Students –One-on-one Mentoring –Other ? Renewable Energy Parks16
