PROPOSED SCOPE OF

FERC REGULATORY OVERSIGHT OF

BPA’s TRANSMISSION FUNCTION

Minimum Criteria that any Regulatory Oversight Arrangement Must Meet

1. The Federal Energy Regulatory Commission ("FERC") must have meaningful oversight of BPA’s transmission rates, terms and conditions, with no relevant issue outside the scope of FERC review.

2. The regulatory criteria that FERC applies must give protection of customers’ interest co-equal standing with protection of the interests of BPA’s transmission business.

3. Protection of BPA’s power related interests must be an impermissible criteria for establishing or reviewing BPA’s transmission rates, terms, conditions or standards of conduct. To the extent any charges are levied for purposes of "total cost recovery" in the power business (as opposed to transmission cost recovery), to lend security for third-party power related debt or otherwise, such charges must be treated as exceptional events subject to strict criteria and not part of transmission ratemaking.

4. Ambiguities regarding the substantive standards for BPA’s transmission rates terms and conditions must be eliminated. BPA should be subject to the exact standards to which IOUs are subject except to the extent, if any, that explicit narrow alternatives are provided to address BPA’s capital structure.

1. To what degree must the BPA’s costs be functionalized to transmission and generation for rate purposes?

Strict FERC Equivalency:
Unless otherwise allowed under the just and reasonable standard, transmission rates would be required to be based exclusively on transmission costs as defined by the FERC Uniform System of Accounts.
Proposed Rule:
BPA should be subject to Strict Equivalency on this issue.

BPA should be required to account for its costs (both investments and expenses) pursuant to the FERC Uniform System of Accounts. BPA should substantially improve its accounting for corporate overheads associated with transmission and generation such that most such cost can be directly assigned to the appropriate function when incurred and the need for after-the-fact allocations are kept to an irreducible minimum.

BPA’s transmission rates should be set in accordance with FERC’s transmission pricing policies. [See Item 5]

1.A. Should BPA be permitted to diverge from the just and reasonable standard normally applicable to transmission rates to address cost recovery problems of the BPA’s power business?

Strict FERC Equivalency:
BPA would be prohibited to establish transmission rates, terms or conditions to recover power related costs or in any way to provide special advantage to its power business.
Proposed Rule:
Ratemaking. There must be no exceptions built into the criteria for the normal course of transmission ratemaking to address problems of cost recovery, the environment, or security for third-party debt that arise in BPA’s power business line. Ideally, the repayment obligations for transmission and power would be separated completely as a matter of law. If it were ever appropriate to recover costs associated with the power business through some form of transmission related charge, any such charge should be developed based on specific and rigorous criteria specifically adopted to address such issue. Such charge should also be stated separately from transmission rates.

Cash Management. BPA should not be permitted to use its available cash to meet its overall (i.e., power) cash requirements unless BPA properly accounts for the use of cash. BPA’s cash management practices should not be allowed to adversely affect transmission rates. [ The proposal for "cash management" is based on the assumption that it will be deemed appropriate to provide for full recovery of transmission costs with transmission rates, no matter what ( i.e. , that the U.S. Treasury accepts no risk for transmission cost recovery). An alternative would be to adopt a risk premium approach to capital recovery that provides the Federal government with the equivalent of an equity return, and to have the Federal Treasury bear the risks that from time to time, revenues will fall short of expectations. The "equity return" approach would allow for the adoption of strict FERC equivalency on all ratemaking issues (Issue Nos. 1, 2, 3, and 4). For example, if BPA chose to use some of the cash associated with the equity return on transmission assets to pay power bills ( i.e. , if Treasury agreed to subsidize a loss in the power business by foregoing some or all of its return), that would be acceptable.]

In the event of an actual shortfall (as opposed to forecasting a shortfall as part of setting rates) between revenues and cost (expenses plus planned payments to Treasury) in either the generation or transmission function, primary reliance should be on using all lines of credit, such as unused borrowing authority, and all repayment flexibility available to the function experiencing the revenue shortage.

After exhausting all other sources of credit, an interfunctional loan payable with market based interest on a specific schedule could be allowed for nonrecurring shortfalls. The loan repayment should be reflected in future rates of both functions (i.e., a cost to the borrowing function and a revenue source to the lending function). Any future surplus in the borrowing function would be dedicated first to prepayment of the loan. Any such interfunctional loan would be a last resort and would be subject to strict controls to protect transmission customers. In the event an interfunctional load is triggered, a complete independent audit of the function suffering the deficiency should be mandated.

As noted above, anticipated or chronic shortfall of revenues in one function to cover the cost of that function should be addressed as an extraordinary event subject to special rules.

2. How must BPA’s capital costs be calculated for ratemaking purposes?

Strict FERC Equivalency:
BPA’s capital recovery would include only depreciation and interest (or some reasonable measure of "return on capital").
Proposed Rule:
FERC should adopt a method of calculating capital costs that provides for recovery of BPA’s capital investment (with interest) over reasonable period of time (i.e., closely related to the life of the assets), that provides adequate but not excessive risk coverage and that does not produce excessive rates.

The capital recovery portion of BPA’s rates should be set to recover interest plus depreciation (instead of interest plus the higher of depreciation or amortization) plus a "risk premium" that could be modeled after FERC’s treatment of non-IOU capital needs. An upper bound must be set on the cash reserve that BPA would be allowed to accumulate by charging a risk premium based on the actual needs of the transmission business.

3. To what degree should past unanticipated revenue shortfalls or surpluses be permitted to be reflected in future rates (i.e., retroactive ratemaking)?

Strict FERC Equivalency:
Retroactive ratemaking is not permitted.
Proposed Rule:
FERC could apply a ratemaking standard to BPA that allows future transmission rates to recover (or return) deficits (or surpluses) arising from the transmission function over a reasonable period of time. Such a practice is acceptable only to the extent that the "risk premium" is correspondingly reduced to reflect that part of the transmission business risk is covered by the potential for retroactive ratemaking.

Under no circumstances should normal transmission rates be raised to address shortfalls incurred by the power business line.

4. Does FERC have any role in determining the reasonableness or prudency of BPA’s expenditures so as to include or exclude them from transmission rates?

Strict FERC Equivalency:
FERC would be required to approve recovery of past costs (including costs associated with historic commitments) but, FERC could disallow for rate purposes the costs associated with imprudent post-separation expenditures. (In effect, past expenditures are grandfathered.)
Proposed Rule:
It is imperative that FERC have the authority and the duty to prohibit including non-transmission costs in transmission rates and to determine the reasonableness of any forecasts or provisions for contingencies (e.g., risk premiums) in determining just and reasonable transmission rates. Because ratemaking is prospective, FERC would have no reason to "disallow" expenses as opposed to judge the reasonableness of forecasted expenses. It is not necessary to give FERC any regulatory authority to determine whether BPA’s transmission investments were prudent as long as such investments are subject to Congressional appropriation.

5. How are BPA’s transmission rates set?

Sub Issues:

Strict FERC

Equivalency:


The 7(i) process would be eliminated, and BPA’s proposed transmission rates would be approved or modified based on a just and reasonable standard as determined in an evidentiary hearing before FERC in which BPA had the burden of proof. FERC’s decision would be reviewable by a United States Circuit Court (D.C. Circuit or Ninth Circuit) which would grant substantial deference to FERC’s decisions.
Proposed Rule:
a. Record Development. BPA should continue to establish transmission rates based on a 7(i) record developed in the region by BPA. This will allow BPA and customers jointly to develop mutually acceptable solutions within the boundaries permitted by law. However, the substantive standards that BPA must use in setting rates and the deference given to BPA at FERC and on judicial review of such rates must be revised significantly for clarity and to assure compliance with the standards.

b. Substantive Standards. BPA’s rates must meet the just, reasonable, nondiscriminatory and nonpreferential standards applicable to IOU rates, and, subject to issues #2, 3, and 4 above, such standards must be given the same meaning for BPA as those terms have for IOUs. (We believe this is now the law under the "equitable allocation" standard in the Transmission System Act and the prohibition against unjust, unreasonable, or unduly preferential or discriminatory transmission rates in EPA-92.) Any ambiguity that the obligation to "recover total costs" produces a result different from the normal just and reasonable standard must be eliminated.

c. Relevant Issues. FERC has regulatory jurisdiction over all issues relevant to BPA’s transmission rates.

d: Who Decides and What Standards of Deference Are Applicable. After BPA has tendered proposed rates to FERC for review, with the evidentiary record to support the rates (as developed under 7(i)), in FERC’s review:

• FERC would not be permitted to substitute its judgment for BPA’s on policy and discretionary issues as long as BPA’s proposed rates were based on reliable facts and meet the minimum requirements of applicable law (as interpreted by FERC). (Deference to BPA’s judgment.) In order to ensure that BPA could always exercise its discretion, any deficiencies in BPA’s rates would be remanded to BPA for correction. The law should be clear that a reviewing court could reverse FERC if FERC substituted its judgment for that of BPA.

• FERC would decide all issues of law, specifically that the proposed rates are not unjust, unreasonable, unduly discriminatory or preferential. (No deference to BPA.)

• FERC would review BPA’s decision and decide all disputed issues of fact raised by the parties at FERC based on the record developed in BPA’s full hearing. If FERC deems the record to be inadequate, it would remand to BPA to supplement. (No deference to BPA.)

• FERC’s decision (not BPA’s) would be reviewable under the Federal Power Act in the Ninth Circuit or D.C. Circuit Courts of Appeals. BPA and interested parties could appeal FERC’s decision. FERC’s decision would be reviewed under the 5 USC § 706 standards (e.g., arbitrary, capricious, unsupported by the record, not in accordance with law) which implies substantial deference to FERC’s decision.

This approach provides BPA with full discretion to establish its transmission rates in any fashion consistent with the outer boundaries established by law. Moreover, the continued use of the 7(i) process by BPA in the region assure that there would be no diminution of customers’ input into how those discretionary choices are made. Allowing FERC to interpret the law (i.e., the just and reasonable standard) assures consistency between the legal protection provided BPA’s transmission customers and the protection provided to customers using other systems. Allowing FERC to resolve disputed issues of fact assures an unbiased fact-finder. For example, if BPA continues to treat the southern intertie as a separate function, FERC could not require otherwise unless there were no factual basis for BPA’s decision, or BPA’s decision violates the law. It would not be enough that FERC might prefer a different result.

d. Procedural Issues. Unless otherwise specified by contract or existing law, BPA’s hearing would occur in Portland before a FERC ALJ for general transmission rate cases, as determined by FERC for § 211 requests, and as determined by BPA for other proceedings.

Hearings would be subject to the ex parte rule at BPA (to assure that BPA’s initial decision is based on the record) and BPA as well as parties would be subject to the ex parte rule at FERC.

The ALJ would issue a recommended decision which would not be binding on BPA (no deference). BPA’s decision could incorporate the ALJ recommendations and reasoning, or adopt different outcomes or reasoning, as long as the differences were adequately explained.

Transmission rates and supporting record would be filed at FERC under current procedures applicable to BPA, modified as appropriate to address the changes recommended herein.

6. For what period are BPA’s transmission rates valid?

Strict FERC Equivalency:
FERC approves rates for an indefinite period, and it can investigate the continued reasonableness of existing rates on its own motion or in response to customer complaints. BPA may submit new rates for FERC approval at any time.
Proposed Rule:
Adopt equivalency.

7. Does FERC have jurisdiction over a decision by BPA to offer, modify, withdraw or discontinue any class of service?

Strict FERC Equivalency:
Yes. FERC would have jurisdiction over all of BPA’s decisions affecting transmission rates, terms and conditions. (This does not mean that contracts would automatically be extended beyond their terms or that BPA would be locked into the particular set of terms and conditions that presently exist. It means only that FERC would need to agree any changes were reasonable.)
Proposed Rule:
Adopt equivalency.

8. Does FERC have jurisdiction over BPA transmission contracts?

Strict FERC Equivalency:
BPA would file all transmission contracts with FERC and, FERC would review contracts for reasonableness prior to their effectiveness. FERC could modify rate terms in contracts in certain narrow circumstances (e.g., threatens the financial viability of the utility). FERC also has the authority to interpret the contracts and resolve disputes arising from approved contracts.
Proposed Rule:
All new BPA transmission contracts should be subject to full FERC review of the same type applicable to IOUs.

FERC should have no role to review or modify existing transmission contracts, but it may be appropriate to grant FERC an expanded role in interpreting such contracts to resolve disputes.

9. On what criteria should FERC judge requests for access to BPA’s transmission system?

Strict FERC Equivalency:
BPA should be subject to criteria identical to that applicable to IOUs (i.e., non-discriminatory comparable access with a preference for "native loads" in the event of competing requests for access over constrained paths).
Proposed Rule:
Preserve all existing access rights by statute and adopt equivalency on the applicable criteria for judging specific requests for transmission service.

10. Should legislation remove any unique barriers to BPA joining an ISO?

Strict FERC Equivalency:
By definition, any barriers unique to BPA are inconsistent with equivalency.
Proposed Rule:
This question is not related to the regulation of BPA’s transmission rates, which is the topic of this paper. Moreover, there is no reason to worry about barriers to BPA joining an ISO unless and until some form of ISO that could potentially benefit BPA’s customers is developed. At the moment, IndeGO’s costs exceed its benefits and, if BPA joins IndeGO, costs would be shifted to BPA’s customers.

11. What role should FERC have regarding BPA’s participation in an ISO?

Strict FERC Equivalency:
FERC has broad authority over ISOs. It is uncertain whether FERC can order an IOU to join an ISO.
Proposed Rule:
Same answer as Issue 10.

12. How should BPA recover stranded costs from bundled power customers that become transmission only customers?

Strict FERC Equivalency:
Unless otherwise covered by contract, BPA should only recover legitimate, verifiable and prudent costs previously incurred with the reasonable expectation of continuing service to specific customers through targeted charges to such individual customers. Stranded costs are calculated as the difference between expected revenues from the reasonably expected sales (minus mitigation) and the market value of the power.
Proposed Rule:
Effective management of BPA’s power system should prevent BPA from any long-term cost recovery problem on its power system. Customers should work with BPA to determine whether a workable special "contingent cost recovery mechanism" is appropriate for BPA.
