3 REVISED UPDATED PREPARED DIRECT TESTIMONY OF JASON BONNETT I. QUALIFICATIONS My name is Jason Bonnett. My business address is 80 Century Park Court, San Diego, California, I am employed by San Diego Gas & Electric Company (SDG&E) as a Principal Regulatory Economic Advisor in the Regulatory & Rate Strategy Department of SDG&E and Southern California Gas Company (SoCalGas). I hold a Bachelor of Science degree in Business Administration from Mankato State University, a Juris Doctorate from Hamline University School of Law, and a Master of Arts in Public Administration from Hamline University. I have been employed by SDG&E since Prior to joining SDG&E, I was employed by the Minnesota Department of Commerce, Energy Division, as a Public Utilities Rates Analyst from May 1998 through July I have previously testified before the California Public Utilities Commission (Commission) II. PURPOSE & OVERVIEW OF RATE DESIGN The purpose of my testimony is to present SoCalGas proposed natural gas transportation rates. These rates rely upon the cost allocation of authorized base margin costs among customer classes as shown in the prepared direct testimony of Mr. Lenart. A. Overview The SoCalGas rate design model takes the allocated base margin provided by Mr. Lenart and incorporates the transmission system with SDG&E along with unbundling the Backbone Transmission Service (BTS). Additionally, the SoCalGas rate design model allocates the cost within the noncore market for the Transmission Level Service (TLS) rate, and non-margin costs - 1 -

4 which (for ratemaking purposes) reflect other costs incurred by the utility to provide basic transportation services to its customers during the forecasted cost allocation period. These nonmargin costs reflect, but are not limited to, regulatory account balance amortizations, gas-engine rate cap, and Enhanced Oil Recovery (EOR) revenue treatment. B. Non-Margin Cost Allocation and Rate Design Proposals Except as noted below, the methods employed to develop and allocate non-margin costs are consistent with the methods employed to develop the SoCalGas transportation rates adopted in Commission Decision (D.) , SoCalGas most recent cost allocation proceeding decision. The following lists the non-margin cost allocation and rate design proposals incorporated in my testimony: 1) Residential and Core Commercial and Industrial (C&I) rates fully de-averaged; 2) Maintain the residential baseline/non-baseline cap; ) Update the submeter credit; ) Propose a consistent allocation within and among the core C&I and noncore C&I classes; 5) Update Natural Gas Vehicle (NGV) compression costs; 6) Provide TLS Revenue Report; 7) Propose allocation method for Compressor Station Fuel and Power Balancing Account; and 8) Propose increasing Rule 8 C&I incentive cap

5 C. Illustrative Rates The non-margin cost allocation results are added to the results of the base margin cost allocation to complete the transportation rate revenue requirement. The completed transportation revenue requirement becomes the starting point for any rate design calculations. The proposed changes in SoCalGas class-average transportation rates are shown below in Table 1. The rates in Column B include the transition adjustments proposed in the testimony of Mr. Lenart and correspond with those shown in his Table 16, while column D incorporates the forecasted regulatory account balances from the testimony of Mr. Ahmed and correspond with the rates shown in Appendix A of this testimony.

6 1 2 Appendix A contains a complete set of rate tables using the proposed cost allocation method which represents this proposal. III. CORE RATE DESIGN In this section, SoCalGas updates its individual core rates. This section describes specific changes to current rate design methods for core customers. A. Core De-Averaging SoCalGas is no longer including any core averaging adjustment. Instead, SoCalGas is proposing to make a Transition Cost Adjustment pursuant to Section IX of Mr. Lenart s testimony. B. Residential Rates These rates are applicable to three categories of residential customers: single-family, multi-family, and small master metered dwellings (master meters with loads less than 100,000 therms of weather normalized usage for the past two calendar years). Current residential rates consist of a $0.168 per meter per day customer charge and a two-tiered usage structure: baseline (BL) and non-baseline (NBL) volumetric rates. The current targeted composite tier differential between SoCalGas BL and NBL transportation rates is 1.15 (i.e., the NBL rate is fifteen percent higher than the composite BL rate). The composite BL rate is equal to the sum of the customer charge revenues and BL volumetric rate revenues divided by the BL volumes; however, the rate difference between the BL and NBL is currently capped at $0.26/therm. SoCalGas proposes that the cap be maintained at $0.26/therm throughout the Triennial Cost Allocation Proceeding (TCAP). - -

7 C. Submeter Credits Submeter credits apply to customers with a master meter that provides service to residential sub-units (e.g., multi-family dwelling units and mobile home parks). D established a method for calculating submeter credits. In that decision, certain categories of costs were defined as Utility Avoided Costs which are costs for which the owner of a master meter is reimbursed through the discount provided by the utility (to the extent these costs do not exceed the average costs the utility would have incurred in providing direct service). In this proceeding, SoCalGas proposes to update the submeter credit in compliance with the agreedupon methodology for the calculation of submeter credits set forth in D Currently, submeter credits are set at $0.0805/meter/day SoCalGas proposes to set them at $0.257/meter/day. D. Core C&I Rates SoCalGas has a single tariff serving its core commercial customers, Schedule G-10. Presently, the G-10 rate design consists of a $15 customer charge and three tiers of declining block volumetric rates. In D , the Commission approved the current procedure for determining the rate structure for the different tiers within SoCalGas G-10 rate design. Currently, non-base margin costs, which are all costs associated with other operating costs and revenue as well as regulatory balancing accounts and adjustments, are allocated to the tiers on an Equal Cents per Therm (ECPT) basis. However, not all of these non-base margin costs are allocated to the class on an ECPT allocation. Many are allocated on an Equal Percent Authorized Margin (EPAM) basis, such as the Pension Balancing Account, PBOP Balancing Account, Rewards & Penalties Balancing Account, etc. Thus, in order to promote a consistent allocation within the core C&I - 5 -

8 class, SoCalGas proposes to combine those non-base margin costs not allocated on an ECPT basis with base margin costs. E. NGV Compression Cost Update The NGV Compression Rate Adder has been updated to reflect current costs and proposed allocation of those costs. This amount is composed of the return on ratebase plus the capital related revenue requirement and any related operations & maintenance expense. The embedded cost compression revenue requirement for SoCalGas is $1.15 million, as was presented in my supplemental testimony dated March 16, The proposed revenue requirement is lower due to reduction in capital related expenses IV. NONCORE RATE PROPOSALS A. TLS Rates Pursuant to D , Appendix A, Section II.B..M.b, SoCalGas is required to include data on actual revenues from service provided under the TLS Reservation Rate Option and actual volumes of service provided under that Option. Therefore, SoCalGas presents the following table in compliance with the Commission s decision. Table 2: TLS Reservation Rate Report Intrastate Transmission Level Service (TLS) Transportation Revenues and Volumes Time Period: 02/2010 (BCAP 2009 start) to 08/2011 (for SCG and SDGE) Reservation Service Transmission Revenue ($000) $71,809 Volumes (Mth),76, B. Noncore C&I Distribution Rates SoCalGas current service for noncore C&I customers is provided under Schedules GT-F and GT-I. The current rate design consists of a single customer charge of $50 per month and four tiers of declining block volumetric rates. Similar to the Core C&I rate, in order to promote a 1 A , Supplemental Direct Testimony of Jason Bonnett, dated March 16, 2012, page

9 consistent allocation within the non-core C&I class, SoCalGas proposes to combine those nonbase margin costs not allocated on an ECPT basis with base margin costs. V. OTHER PROPOSALS A. Compressor Station Fuel and Power Balancing Account (CFPBA) As discussed in the testimony of Mr. Ahmed, the CFPBA was established to record actual costs for electricity used in the operation of SoCalGas compressor stations pursuant to the 2008 General Rate Case Decision (D ). The purpose of my testimony is to propose an allocation methodology for recovery of CFPBA costs in rates. Since the CFPBA is designed to track electricity costs used for the transmission of natural gas, SoCalGas proposes that the CFPBA be allocated similarly to other transmission related regulatory accounts and be allocated based on a Cold-Year Throughput (CYTP) basis. B. Increase Rule 8 C/I Incentive Cap SoCalGas proposes to increase the maximum allowed equipment incentive cap in Rule No. 8, Commercial/Industrial Equipment Incentive Program (Rule 8) from 50% of project cost with a maximum $100,000 cap, to 50% of project cost with a maximum $500,000 cap. Similarly, SoCalGas proposes a revision to increase the maximum allowed feasibility studies cap in Rule 8, from 50% of the study cost with a $20,000 maximum per study, to 50% of the study cost, with a $50,000 maximum per study. The Rule 8 program provides shareholder-funded incentives to nonresidential customers within SoCalGas service territory for the objective of assisting customers in buying-down the first-cost of qualifying high-efficiency equipment and/or emerging technology. The program also funds feasibility studies to evaluate the potential benefits of these types of gas equipment. The Rule 8 program was implemented with the approval of AL 216 filed in June 199. Rule - 7 -

10 is a market development effort, funded entirely by shareholders to encourage energy-efficient gas equipment purchases by both large and small core and noncore nonresidential customers in SoCalGas service territory. The objectives of the program are to: a) Persuade nonresidential customers to install state-of-the-art equipment to reduce their overall energy cost and increase their productivity and/or profitability. b) Encourage and support manufacturers of gas equipment to develop and produce new, cost-effective and energy-efficient nonresidential equipment for southern California. c) Demonstrate SoCalGas commitment to develop and promote new, alternative technologies with environmental and/or energy-efficiency benefits. d) Increase the amount of nonresidential gas equipment with high off-peak load usage by: (1) better utilizing SoCalGas pipeline capacity during the summer months, and (2) reduce average operating costs by balancing system load. e) Demonstrate that innovative nonresidential gas equipment is a viable and environmentally beneficial alternative to traditional gas and electric technologies. The purpose of raising the program incentive cap is to minimize the loss of project opportunities. With an increased incentive cap, the program is better able to meet its purpose of helping customers buy down the first-cost of gas equipment. Ratepayers and shareholders mutually benefit from projects stimulated by Rule 8. Shareholders benefit from the incremental transportation revenue generated by the added-load project for the length of the Rule 8 contract, whereas ratepayers benefit immediately from the incremental PPPS (Public Purpose Program Surcharge) revenue generated by the added-load, and will also benefit from the incremental transportation revenue subsequent to the Rule 8 contract expiration. Raising the incentive cap will also support the Commission s goal of increasing CHP installations, which are a critical - 8 -

According to the California Air Resources Board s AB2 scoping plan, meeting California s 2020 greenhouse gas reduction goals will require installation of,000mw of new CHP capacity. 2 This concludes my revised updated prepared direct testimony. 2 California Air Resources Board for the State of California.
