  1. Energy Storage: Addressing Today’s Grid Challenges for Tomorrow’s Energy Demands Brad Roberts Power Quality Systems Director S&C Electric Company Grid Week September 2011

  2. The Grid Connected Energy Storage Market is Large….. Estimated Global Installed Capacity of Energy Storage Source: StrateGen Consulting, LLC research; thermal storage installed and announced capacity estimated by Ice Energy and Calmac. Note: Estimates include thermal energy storage for cooling only. Figures current as of April, 2010.

  3. Grid-Purposed Energy Storage - Hierarchy Large Central Units 100s of MW Substation Batteries 10s of MW Graphics adapted from an EPRI Presentation by Joe Hughes Storage at Grid Edge 10s of kW

  4. Prepare for new Revenue Models Prepare for new Renewable & Reliability Mandates Prepare for new Customer Behaviors Grid Storage Benefits All three must work together synergistically to justify widespread storage deployment 3- Market Benefits 2- Service Benefits • Energy Arbitrage • Frequency Regulation • Generation Capacity • T&D Capital Deferral • Service Reliability (DA) • Improve System Efficiencies • Voltage Regulation 1- Strategic Benefits

  5. Layered Intelligence Reaction Times

  6. Smart Grid Projects with Storage

  7. Smart Grid Projects with Storage

  8. Integration Utility Dispatch Platform Center /SCADA Substation CES CES CES CES CES – A Virtual Substation Battery CES is Operated as a Fleet offering a Multi-MW, Multi-hour Storage • Local Benefits: • 1) Backup power • 2) Voltage correction • 3) Renewable Integration • Grid Benefits: • 4) Load Leveling at substation • 5) Substation Power Factor Correction • 6) Ancillary services CES Control Hub Communication & Control Layout for CES

  9. AEP Ohio and S&C Debut First Lithium-Ion-Based CES • First CES units in the world to be installed at customer homes • Sensing technology in CES units recognizes when homes lose electric power, and automatically provides back-up for up to several hours • S&C is contributing significant technological expertise to the AEP Ohio gridSMART Demonstration Project, providing customers greater energy control and improving electric distribution service and performance

  10. Next Steps for Storage • DOE Smart Grid and Storage stimulus projects will confirm the value of storage • Wyden Storage Act would provide the much needed Investment Tax Credits to stimulate growth • Storage participation in the Ancillary Services market has proven very effective • Storage will be a key component of higher penetration of renewables and electric transportation
