California’s Policy Goals: Details

• 50% of retail energy from renewable power by 2030
• Greenhouse Gas Emissions Reduction to
• 40% below 1990 levels by 2030
• 80% below 1990 levels by 2050
• Shut down powerplants using coastal water for cooling
• Increased distributed generation, including storage
• 5 million zero emission vehicles by 2030

California Storage Policy Approaches

12 Statutes Mandates

• Legislation
• Mandated Procurement
• Technology Neutral & Diversity of Size
• Priority over fossil fuels for grid resiliency

Incentives Processes

• BTM*: Self-Generation Incentive Program
• Interconnection
• Resource in Wholesale Markets
• Rate design: Time of Use; Net Metering

Expanded Revenue

• Long-term Contracting
• Multiple Use Applications: Storage/Solar
• Ancillary Services and Load Shifting
• Integrate Renewables

Cost

• Storage costs exceeded other resources for

all applications

Technology

• Technologies are under development and

have not yet gone to scale

• Applications may not match grid needs

e.g. duration

Timing

• Procurement process and permitting may

cause delays
