DISCLAIMER

Duncan & Allen 4

This report addresses only BWP’s and GWP’s preliminary findings as of the date of this presentation.  BWP and GWP believe that revisions to these findings and additional findings are likely to occur, if and when they receive the information and data they have requested from LADWP.  BWP and GWP reserve the right to raise additional findings and plan to do so, if necessary, in the public stakeholder process.  

Page 5: PRELIMINARY FINDINGS OF BWP AND GWP REGARDING …€¦ · 6. BWP and GWP hereby request that LADWP rectify this situation and provide them with the information they have requested,

APPLICABILITY OF FPA SECTIONS 211 AND 212 TO LADWP’S OATT AND OATT RATES

1. LADWP’s OATT and OATT rates are subject to the FERC’s authority over transmission under Sections 211 and 212 of the FPA.  See e.g., City of College Station, TX, 76 FERC ¶ 61,138 (1996).

2. If LADWP fails to resolve the OATT and OATT rate issues set forth in BWP’s and GWP’s preliminary findings, these issues can be brought before the FERC for resolution. See e.g., City of College Station, TX, 99 FERC ¶ 61,163 (1996).

3. BWP and GWP hope to avoid a complaint at FERC.

PROCEDURAL ISSUES

1. LADWP has not fully and promptly responded to BWP’s and GWP’s information requests in this Stakeholder process.

2. Since the process began, BWP and GWP have asked a total of 88 questions, many with subparts.  As of today, some responses have been denied, some responses are late, some responses are inadequate, and responses 48‐88 have not yet been posted.  We are separately providing a table that shows each of the information requests and either a description of BWP’s and GWP’s concerns regarding the answers provided or a note that no response has been provided yet. 

3. Some requests submitted on February 1, 2017 have not yet been responded to. 4. Of the questions actually answered, some were not fully and completely answered or responded 

to with data that was not responsive or provided in  non‐searchable and/or native format.5. Because LADWP has not fully and completely responded to BWP’s and GWP’s information 

requests, they cannot complete their analysis of multiple aspects of LADWP’s OATT and COSS proposal (e.g., classification, segmentation, return‐on‐equity, capital structure, income or receivables associated with LADWP’s role as Project Manager for SCPPA ,IPA, and PDCI owners).

6. BWP and GWP hereby request that LADWP rectify this situation and provide them with the information they have requested, LADWP is required to provide and which they have a right to receive.  

7. If LADWP’s responses are not provided this week, the Stakeholder Process should be suspended until such time that all  full and complete responses have been provided.

COSS Issue 1 – Rate Design

1. LADWP’s COSS inappropriately uses an average of 12 Coincident Peak (“CP”) for calculating rates in conditions where 1 CP is appropriate, justified and required by FERC precedent.a) LADWP’s use of a 12 CP is not appropriate because LADWP fails  the following 3 Tests: 

1) Test No. 1 ‐ On and Off Peak Test ‐ This test first compares the average of the coincidental peaks in the months with the three highest system peaks as a percentage of the annual system peak. Second, it compares the average of the coincidental peaks in the three months with the lowest system peaks as a percentage of the annual system peak. A 12 CP allocation is considered appropriate where the difference between these two percentages is 19% or less.

2) Test No. 2 ‐ Low‐to‐Annual Peak Test ‐ Compares the lowest monthly peak as a percentage of the annual system peak. A range of 66% or higher is considered indicative of a 12 CP system.

3) Test No. 3 ‐ Average to Annual Peak Test – Compares the average of the twelve monthly peaks as a percentage of the annual system peak. A range of 81% or higher is considered indicative of a 12 CP system. See e.g., Southwestern Pub. Serv. Co., 144 FERC ¶61,133, P48‐51 (2013); Golden Spread Electric Co‐Op, Inc., Order No. 501‐A, 144 FERC ¶61,132 (2013); and American Electric Power Service Corporation, 64 FERC ¶61,279 (1993).

b) 1CP is appropriate because LADWP plans for its peak which usually is in one month of the Summer. See e.g., “LADWP’s 2013 Long‐Term Transmission Assessment, Dec. 23, 2013, p. 7, noting that compliance with NERC reliability standards is demonstrated by summer 1‐in‐10 peak conditions.

c) BWP and GWP loads should be included in the LADWP’s Native Load for purpose of calculating 1CP because they meet the OATT definition and are not included in the Native Load of any other Control Area.

COSS Issue 1 – Rate Design – Solutions

1. LADWP should replace its 12 CP with a 1 CP so that its OATT rates (a) accurately reflect how LADWP plans for its system peak and (b) do not violate FERC precedent.

2. LADWP should include BWP’s and GWP’s loads in the calculation of Native Load for purpose of calculating 1CP so that this calculation is consistent with LADWP’s OATT definition of “Native Load.”

COSS Issue 2 – Segmentation

1. LADWP’s COSS inappropriately rolls together the Pacific DC Intertie (PDCI), the Southern/Northern Transmission System (STS/NTS), and the Beltline AC network.

2. The PDCI and STS/NTS facilities should be excluded from the Beltline and separate rate schedules should be established for each of these transmission segments because:a) The PDCI and STS/NTS facilities are not actually integrated to the 

LADWP Control Area;b) The PDCI and STS/NTS facilities are segregated by LADWP when 

determining Real Power Losses;c) The STS was originally built to move only the IPP generation plant 

output to southern California; andd) LADWP has not demonstrated that it has exercised rights to use the 

NTS  via an option in the agreement between IPA and LADWP.

COSS Issue 2 – Segmentation – Solution

The costs of the PDCI and STS/NTS should be excluded from the Beltline revenue requirement and separate rate schedules should be established for each of the three  segments.Rate divisors for each segment should comport with FERC precedents.

COSS Issue 3 – Revenue Credits

1. LADWP’s transmission revenue requirement in the 2017 OATT COSS fails to fully document and accurately account for the revenues, payments and cost offsets that LADWP receives under at least the following agreements or arrangements:a) SCPPA‐LADWP Agency Agreementsb) PDCI – Contracts between BWP and GWP for O&M and capital 

improvementsc) STS/NTS/IPP – Intermountain Power Project Construction Management and 

Operating Agreement2. LADWP’s failure to reflect these revenue credits, payments and cost offsets in its 

COSS, overstates the OATT rates by the amount of those credits, payments or cost offsets and results in the unlawful double recovery of transmission costs. See, e.g., Nev. Power Co.,  153 FERC ¶ 61,306 at P 46 (2015) (rejecting a transmission providers double recovery of transmission costs); Order No. 888‐B, 81 FERC P 61,248 at 62,096 (directing transmission providers to design rates that will avoid double recovery of such transmission costs or ancillary costs).

COSS Issue 3 – Revenue Credits – Solution 

LADWP’s COSS should be revised to fully document and accurately reflect the revenues, payments, and cost offsets that LADWP receives for the provision of services related to transmission and generation facilities included in the LADWP OATT.

Page 15: PRELIMINARY FINDINGS OF BWP AND GWP REGARDING …€¦ · 6. BWP and GWP hereby request that LADWP rectify this situation and provide them with the information they have requested,

COSS Issue 4 – Classification and Functionalization

1. LADWP inappropriately includes in the OATT revenue requirement the costs of facilities, which do not qualify or function as transmission facilities but instead are either production  facilities or distribution facilities.  

2. The inclusion of these facilities violates FERC’s precedent which prohibits the rolling‐in of facilities that cannot  and are not used by OATT customers, are not integrated into the LADWP system and  do not provide benefits to OATT customers.  See e.g., Ky. Utils. Co., 85 FERC ¶ 61,274, at 62,111‐13 (1998) (finding that generation step‐up transformers should be excluded from rolled‐in transmission rates); Nevada Power Co., 100 FERC ¶ 61,077, at P 13‐14 (2002) (excluding the costs of radial generator leads from rolled‐in transmission rates, even though they are transmission facilities).

3. The following facilities that should be excluded from the OATT revenue requirement because they provide only gen‐tie functions for generators (Upper Gorge, Middle Gorge, and Control Gorge) used to serve LADWP’s retail load:a) Inyo  Switching Stationb) Barren Ridge Switching Stationc) Haskell Switching Stationd) Inyo‐Barren Ridge Linee) Barren Ridge‐Haskell Linef) Haskell‐Olive Line  

4. The listed facilities are gen‐tie facilities for generators that are not under AGC control from LADWP’s ECC. These generators run to a fixed schedule to move water down the Los Angeles Aqueduct, to meet the needs of the Water Department of the City of Los Angeles. The units are block loaded by the Control Operator at Control Gorge Power Plant, after that operator starts the Owens Gorge Units (Upper, Middle, & Control). Shutdown is also accomplished by this operator. 

5. LADWP’s “One‐Line Schematic Diagram, Transmission System Overview, Blackstart Reference (BS‐1)” indicates that the Owens Gorge Units (Upper, Middle, & Control) are not considered Blackstart units.

LADWP should revise its OATT revenue requirement to remove the costs of the following facilities:

a) Inyo  Switching Stationb) Barren Ridge Switching Stationc) Haskell Switching Stationd) Inyo‐Barren Ridge Linee) Barren Ridge‐Haskell Linef) Haskell‐Olive Line

COSS Issue 5 – Ancillary Services 

1. LADWP inappropriately uses a 12 CP to calculate its OATT Ancillary Services rates.  For the reasons detailed previously, this is unlawful and should be changed to 1 CP.

2. LADWP inappropriately relies on a Variable Energy Resource (VER) study that occurred after the test‐year to establish its rates for reliability and frequency response (RFR) Service.

3. LADWP incorrectly uses a VER study to set the Purchase Obligation for RFR service under Schedule 3. RFR service under Schedule 3 is not the same as Generator RFR for VERs under Schedule 10.

4. LADWP has apparently erred in Schedule 10 by setting the Purchase Obligation (PO) for dispatchable resources higher than the PO for non‐dispatchable resources.

1. LADWP should replace the 12 CP with a 1 CP to calculate its OATT Ancillary Services rates. 

2. LADWP should conduct a proper study to determine its RFR capacity needs and related costs for Schedule 3.

3. LADWP should reconsider Purchase Obligations in Schedule 10.

COSS Issue 6 – Fuel and Pre‐paid Energy Costs

LADWP’s inclusion of the costs of fuel stocks and prepaid energy in its OATT revenue requirement is unjustified and inappropriate because it violates the principle of cost causation. See e.g., Black Oak Energy, LLC v. FERC, 725 F.3d 230, 237, 406 U.S. App. D.C. 357 (D.C. Cir. 2013) (explaining that the cost causation principle requires that all rates reflect the costs actually caused by the customer who must pay them); KN Energy, Inc. v. FERC, 968 F.2d 1295, 1300, 297 U.S. App. D.C. 13 (D.C. Cir. 1992) (same).

COSS Issue 7 – Capital Structure and ROE

1. LADWP’s COSS inappropriately relies on a flawed hypothetical capital structure even though it could have used its actual capital structure. See e.g., Valley Elec. Ass'n, 141 FERC P61,238, 62279 (2012) .

2. LADWP has inappropriately used the wrong proxy group in developing its “Return on Equity” (ROE) because the group it used  did not have a single municipality or publicly owned utility, and the group members’ credit ratings were significantly lower than, and not comparable to, LADWP’s credit rating. See e.g., Coakley v. Bangor Hydro‐Electric Co., 147 FERC ¶ 61,234, at P 106 (2014); City of Vernon, 111 FERC ¶ 61,092, at P 96 (2005). The selection of the proxy group violates established FERC precedent.

3. LADWP’s ROE testimony also apparently contains mistakes or mathematical errors, and is inconsistent with FERC Opinions.  (See BWP’s and GWP’s unanswered Request Nos. 51‐58 and 64‐65).

COSS Issue 7 – Capital Structure and ROE – Solutions 

1. LADWP should amend its COSS so that it uses LADWP’s actual capital structure. 

2. LADWP should change the proxy group it used to develop its ROE  so that it includes municipalities and/or publicly owned utilities and entities with comparable credit ratings.  In the alternative, LADWP should develop a replacement methodology that reflects LADWP’s actual risk profile.

2. LADWP has failed to clearly identify which methodology it employs to calculate ATC (e.g., contract path, network ATC, or network Available Flowgate Capacity (AFC)) and to describe in detail the specific mathematical algorithms used to calculate firm and non‐firm ATC (and AFC, if applicable) for its scheduling, operating and planning horizons. Order No. 890, FERC Stats. & Regs. ¶ 31,241 at P 323. The actual mathematical algorithms must be posted on LADWP OASIS, with the link noted in its  Attachment C. Id.

CONCLUSIONS

Duncan & Allen 31

Based on the foregoing, BWP and GWP hereby request that LADWP suspend the 2017 OATT stakeholder process, review these findings, provide responses to all outstanding discovery, and implement the proposed solutions provided.   

If LADWP determines that it would be appropriate to conduct issue‐specific meetings with stakeholders to address some or all of the individual findings, BWP and GWP would welcome such meetings.
