The document summarizes a Smart Grid event discussing battery storage. It includes an agenda for presentations and panel on battery storage applications moderated by Sean Atkins of Alston & Bird. Presenters will discuss regulatory issues around battery storage, Southern Company's battery demonstrations, and GS Battery's PV battery projects in New Mexico and Georgia. The event is sponsored by various organizations and will take place on August 30th in Atlanta, GA.

6. Overview of Regulation of Electric UtilitiesThe Federal Energy Regulatory Commission oversees:Transmission of electric energy Wholesale sales of electric energy (i.e., sales for resale) State authorities (e.g., Georgia Public Service Commission) regulate:Local distribution of electric energyRetail sales of electric energy (i.e., sales to end-users)Many publicly-owned electric utilities (e.g., municipal utilities) are largely self-regulatingSmart Grid: A 360o View of Battery Storage

7. Classifying Electric Utility Assets Regulators set terms and conditions for adding new electric utility technologies and determine cost recovery for those technologies based on the classification of the asset as Generation, Transmission, or DistributionSmart Grid: A 360o View of Battery Storage

8. Electricity Storage Can Provide Many ServicesMaintaining service to transmission customersSupplying reactive power or acting as a virtual replacement transmission circuit in the event of a line trip Generation-related servicesShifting electricity to periods of peak demand Providing ancillary services (e.g., frequency regulation, load-following)Distribution-related servicesProvide voltage support or acting as a virtual replacement distribution circuit in the event of a line trip Support for demand response Smart Grid: A 360o View of Battery Storage

9. Regulatory Uncertainty on Electricity StorageAncillary services Some regions have already adjusted ancillary service rules to accommodate electricity storage. Proposed FERC regulations will also address this issue FERC has issued a Notice of Inquiry on other ancillary services policies and accounting treatment for storage technologies Recovery of storage costs in transmission ratesFERC has reached different conclusions in two recent casesCurrent FERC policy on cost-recovery for electricity storage assets is to address these issues on a case-by-case basisSmart Grid: A 360o View of Battery Storage

10. State Options for Electricity StorageUtilities installing electricity storage to support the distribution system can be included in bundled retail rates In regions with integrated resource planning, electricity storage can be included in the range of available resources to meet a utility’s overall service obligationsPossible specific procurement requirements/targets for electricity storageIn 2010, California passed a law requiring the state utilities commission to determine appropriate targets (if any) for each utility to procure cost-effective electricity storage systemsState regulation of storage is also expected to evolveSmart Grid: A 360o View of Battery Storage
