  1. Electric Rates Workshop:Cost of Service Analysis and Rate Proposals

  2. Agenda Introduction Review of Rate Structure and Proposed Adjustments Customer Bill Impact Mitigation Strategies and Alternatives Rate Comparison to Other Utilities Cost of Service Analysis

  3. 3 Year Rate Proposal: 2.7%, 2.4%, 2.2% Introduction

  4. Project Timeline

  5. Purpose of Analysis and Rate Proposal

  6. Review of rate structure and proposed adjustments

  7. Electric Rate Structure Major Cost Drivers • Distribution and Customer Charges: • Call center, billing, customer service • Distribution system operations and maintenance • Debt service • PAYGO for capital investment Pass-through component: adjusted in accordance with provisions of Light and Power Rate Ordinance to offset changes in the cost of energy, transmission and public benefit programs • Energy Services Charge: • Debt Service for GT5 project • Renewable energy premiums • Cap and trade program • Market gas and energy purchases • Transmission Services Charge: • Operations, maintenance and portion of capital costs for transmission assets Requires Council approval • Public Benefits Charge: • Rebate programs • Assistance programs

  8. Revenue From Each Rate Component

  9. Alignment with City Goals • Maintain fiscal responsibility & stability • Cost Based Rates • Maintain Fiscal Health • Support City Programs • Ensure Public Safety • Distribution Master Plan • Responsible Capital Investment • Support & Promote Quality of Life & Economy • Accurate Meter Reads • Reliable Service • Improve, Maintain & Enhance Infrastructure • Prudent Operations & Maintenance • Regulatory Compliance

  10. Distribution and Customer Charges Number of Full Time Equivalent employees: Distribution Operations & Maintenance FTE: 97.2 Distribution Capital FTE: 74.3 Customer FTE: 32.3 Administrative FTE: 39.0 Total FTE 242.8

  11. Distribution and Customer ChargesRate Design/Modification Current Proposed D&C $ $ 8.5¢/kWh D 11.65¢/kWh 1.5¢/kWh C $7.76 kWh 350 kWh 750 • Existing Distribution and Customer Charge rate structure does not meet cost of service practice • PWP’s proposed recommendation provides more balanced impact among customer groups

  12. Proposed Rate Adjustments: Distribution and Customer Charges

  13. Formula Rate Adjustments for FY2015- Energy and Public Benefits Charge

  14. Energy Charge (Adjusted by formula) Power Supply FTE: 52

  15. PBC Charge (Adjusted by formula) PBC FTE: 7.25

  16. Combined Projected Rate Adjustments • Future adjustments to energy, transmission and PBC rates are uncertain: • Market costs for energy and gas • Renewable energy goals and costs • Results of IRP update • Transmission projects and costs • Efficiency and rebate program goals 8.3% 2.4% 2.2%

  17. Additional Rate Considerations Time of Use Electric Vehicle Feed-in- Tariff Economic Development Rider • Available to new and existing customers adding a minimum of 100 kW to the system load. • Customer must qualify for the City’s Economic Development Program. • Eligible commercial customers will have two discount options. Adjust the time-of-use (“TOU”) pricing periods: Winter hours Summer hours Holidays and weekends are off peak hours • Minimum of 100 kW to 1 MW renewable energy distributed generation. • Incentivize customers to locate their CEC certified facilities at high load concentration areas within the distribution system.  • Contracts for up to 20 years. • Establish electric vehicle rates for single-family residential customers and multifamily residential customers. • On-peak and off-peak rates shall be based on the price of market energy during the period.

  29. Rate Option Impacts

  30. Rate Adjustment History

  31. PWP’s Proposed Rates Remain Comparable to Neighboring Utilities Electric rate comparison to other utilities

  32. Bill Comparisons for Residential Customers Darkest shade indicates higher comparative bill at given level of usage. For example, at 200 kWh/month, Riverside is the highest and Burbank is the lowest. PWP will be mid-range in comparative bills except at the 400 and 500 kWh levels of consumption.
