  6. 6. Overview of Regulation of Electric Utilities<br />The Federal Energy Regulatory Commission oversees:<br />Transmission of electric energy<br /> Wholesale sales of electric energy (i.e., sales for resale) <br />State authorities (e.g., Georgia Public Service Commission) regulate:<br />Local distribution of electric energy<br />Retail sales of electric energy (i.e., sales to end-users)<br />Many publicly-owned electric utilities (e.g., municipal utilities) are largely self-regulating<br />Smart Grid: A 360o View of Battery Storage<br />
  7. 7. Classifying Electric Utility Assets <br />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<br />Smart Grid: A 360o View of Battery Storage<br />
  8. 8. Electricity Storage Can Provide Many Services<br />Maintaining service to transmission customers<br />Supplying reactive power or acting as a virtual replacement transmission circuit in the event of a line trip <br />Generation-related services<br />Shifting electricity to periods of peak demand <br />Providing ancillary services (e.g., frequency regulation, load-following)<br />Distribution-related services<br />Provide voltage support or acting as a virtual replacement distribution circuit in the event of a line trip <br />Support for demand response <br />Smart Grid: A 360o View of Battery Storage<br />
  9. 9. Regulatory Uncertainty on Electricity Storage<br />Ancillary services <br />Some regions have already adjusted ancillary service rules to accommodate electricity storage. Proposed FERC regulations will also address this issue <br />FERC has issued a Notice of Inquiry on other ancillary services policies and accounting treatment for storage technologies <br />Recovery of storage costs in transmission rates<br />FERC has reached different conclusions in two recent cases<br />Current FERC policy on cost-recovery for electricity storage assets is to address these issues on a case-by-case basis<br />Smart Grid: A 360o View of Battery Storage<br />
  10. 10. State Options for Electricity Storage<br />Utilities installing electricity storage to support the distribution system can be included in bundled retail rates <br />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<br />Possible specific procurement requirements/targets for electricity storage<br />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<br />State regulation of storage is also expected to evolve<br />Smart Grid: A 360o View of Battery Storage<br />

  41. 41. Application to Smart Grid<br />CAES:<br /><ul><li>Energy Management, enabling SmartGrid flexibility: Absorb surplus electricity from renewables during off-peak periods in the form of compressed air, and then use the compressed air to generate power during peak demand periods. Zero emissions, efficiency ~70%</li></ul>Adiabatic-CAES: GRC Munich: ADELE project:<br />Unlike other A-CAES, ADELE stores and then uses the immense amount of thermal energy generated during the air compression process to later help produce the electricity.<br />Isothermal-CAES: SustainX (GE funded):<br />The key to I-CAES is a water spray that keeps the air at a constant temperature through the compression and storing process. Allows efficiency to near 90%.<br />Vehicle-to-Grid:<br /><ul><li>Utilizing EV batteries as a SmartGrid DER

  53. 53. Under the current setup, the batteries are charged ONLY from PV so all energy returned to the grid is renewable energy.
  54. 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.</li></ul>Smart Grid: A 360o View of Battery Storage<br />
