Presentation Transcript

  1. Home Power Tackling the Peak

  2. Overview: The Peak Problem Source: City of San Diego

  3. Minimal duration, huge impact Source: CRS Report to Congress

  4. The Effect of Temperature Time of Day

  5. Solution – Home Power Storage • A battery ‘appliance’ that charges during off peak and discharges during peak power Source: greensmith.us.com

  6. Technical Modules – will be prototyped! Comp. UI Power Electronics Rectifier Battery Inverter

  7. Potential Customers • Beachhead • Universities? Eco-developments? • Primary Customer: • Grid operators that need to mitigate peak demand • Secondary Customer: • Residents that are hands-off in high volatility electricity markets

  8. Value Proposition • For Grid Operators • More predictability in electricity demand, and potentially some control (for load shedding or demand spikes) • Save money in electricity production • For Residential Customers • Energy Bill savings • Eco-Friendly; peak power is the most inefficient • Back-up power in the event of blackouts

  9. Current Competitors … all competitors are focusing on a B2B model

  10. Key Next Steps

  11. The time is right… California state regulations will require 200 MW of battery storage by 2020 “behind the meter” in residential applications (1) • Berkeley Energy and Resource Collaborative

  12. Appendix

  13. Basics on Peak Plants… • Peak Plant operate less than 25% of the year (often left) (1) • Responsible for 14% of all energy in the United States (1) • Peak Plant power is 10X (on average) the cost of base-load plant power (often 100X) (2) • The top 100 priced hours account for 10-20% of electricity costs (2) • In California alone, the number of peak plants rose from 34 in 2001 and 69 in 2011 (3) • CRS Report for Congress • US Government Accountability Office • California Energy Commission
