6. Overview of Regulation of Electric Utilities The 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 energy Retail sales of electric energy (i.e., sales to end-users) Many publicly-owned electric utilities (e.g., municipal utilities) are largely self-regulating Smart 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 Distribution Smart Grid: A 360o View of Battery Storage
8. Electricity Storage Can Provide Many Services Maintaining service to transmission customers Supplying reactive power or acting as a virtual replacement transmission circuit in the event of a line trip Generation-related services Shifting electricity to periods of peak demand Providing ancillary services (e.g., frequency regulation, load-following) Distribution-related services Provide 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 Storage Ancillary 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 rates FERC has reached different conclusions in two recent cases Current FERC policy on cost-recovery for electricity storage assets is to address these issues on a case-by-case basis Smart Grid: A 360o View of Battery Storage
10. State Options for Electricity Storage Utilities 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 obligations Possible specific procurement requirements/targets for electricity storage In 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 systems State regulation of storage is also expected to evolve Smart Grid: A 360o View of Battery Storage

43. Controlled charging can be timed to periods of greatest variable DER output, while charging rates can be controlled to provide contingency reserves or frequency regulation reserves
44. Distributed storage: EVs can partially discharge stored energy into the SmartGridCAES: Large scale grid storage, air “battery” can compensate for RE intermittency

53. Under the current setup, the batteries are charged ONLY from PV so all energy returned to the grid is renewable energy.
54. The estimated PV production for the entire year will be approximately 27MWh. This is worth approximately $3,780 per year. The system is also set up for TOU Energy Cost Management. This is accomplished by shifting the stored renewable energy in the battery to coincide with the utility TOU On-peak time period. This is worth approximately $2,066 (See table below). Together, both these benefits are worth approximately $5,850 per year.Smart Grid: A 360o View of Battery Storage

63.
64. The estimated PV production for the entire year will be approximately 50MWh. This is worth approximately $8,500 per year.
65. PV/Battery system cost after federal and state grants/tax incentives was around $116,000 so the payback will be approximately 13 years.Smart Grid: A 360o View of Battery Storage

67. GSB switched to “TOU-EO-5” electric service tariff which is summarized below along with other example rates:Smart Grid: A 360o View of Battery Storage * 12 years is based on rated 1500 cycles @ 50% DOD [batteries used 4 months (122 days) per year]
69. Battery STORAGE BENEFIT Smart Grid Utility: Improved grid reliability with stacked cumulative values , reduce CO2,Deferred Spending for Generation and T&D Customer: TOU Economics, UPS for critical loads Green Social Value The economic payback model varies by Storage location, TOU Utility rates and battery life and cost of the power system Smart Grid: A 360o View of Battery Storage
