Power Rate Adjustments
Load-Based (LB) CRAC


(updated October 2, 2006)

The Load-Based Cost Recovery Adjustment Clause, or LB CRAC, allows an adjustment to the base rates to recover the anticipated augmentation costs to meet load that cannot be recovered with the base rates.

Because BPA will be acquiring this additional power in a highly volatile market, it is not possible to accurately forecast the cost of purchasing this power over the entire five-year rate period. Accordingly, the LB CRAC has been designed to be responsive to changes in the market price of power. Prior to each six month period of the 2002-2006 rate period (beginning October 2001), BPA will establish the LB CRAC for that six-month period. The LB CRAC will be calculated based on the current forecast of forward market prices for each year, shaped, and the amount by which contracted loads exceed BPA's resources. About 90 days after the end of each six-month period, BPA will true up the LB CRAC based on actual augmentation purchases during the period, and a debit or credit will be made to the customer's bill.

BPA establishes the LB CRAC percentage about 90 days prior to the beginning of the next six-month period. Then, about 90 days after the end of the most recent six-month period, BPA calculates the over- or under-collection of actual LB CRAC revenues for the previous six-month period. Any over- or under-collection is treated separately from any charges for augmentation costs for the upcoming six-month period. About 15 days prior to the date that BPA establishes the LB CRAC percentage, BPA will conduct a public workshop to provide all participants with the calculations that were used to develop the LB CRAC.

The final LB CRAC Workshop to True-Up any changes in period 10 of the FY 2002-2006 rate period is scheduled for December 13, 2006.

  • Final LB CRAC 9 True-Up Results (issued June 26, 2006)
    (PDF, 6 pages, 91 kb, posted here on June 29, 2005)
    - LB CRAC 9 True-Up for October 2005 - March 2006
    [Note: This workshop was only required to establish the true-up adjustment for LB CRAC 9. Since no forward looking LB CRAC was determined, Table 1 and 3 - 8 (pages 2 - 5) are omitted from the final LB CRAC results package.  The LB CRAC 9 true-up adjustment posted here is about $330,000 larger than the adjustment discussed in the June 14 workshop. The increase is due to issues identified and corrected during the independent auditor review of the LB CRAC 9 true-up calculations.]

  • REVISED Final LB CRAC Results (revised 01-31-2006)
    (PDF, 10 pages, 99 KB, posted here on February 1, 2006)
    - LB CRAC 10 Adjustment for April 2006 - September 2006
    - LB CRAC 8 True-Up for April 2005 - September 2005 (REVISED)
    [Note: In its audit of the LB CRAC 8 true-up for the April 2005 - September 2005 rate period, BPA's independent auditor discovered a data error in the monthly energy reports used in calculating the true-up.  The consequence is that the Slice and non-Slice customers covered by the Load-Based CRAC owe BPA an additional $1.3 million for the LB CRAC 8 period compared to the preliminary amount announced in the December 14 workshop.]

[Related follow-up announcement]
June 20, 2003 - Decision Regarding LB CRAC Accounting Treatment for the Enron Settlement:   In response to a request from customers at the June 10th LB CRAC workshop, BPA staff met with senior management to discuss the LB CRAC's collection of actual cash outlays versus accruals relative to the Enron settlement. It has been decided that BPA will maintain its position that the amount collected through the LB CRAC for the Enron settlement will be the accrued expenses for the settlement, which are based on the expenses that would have occurred if the augmentation contracts were still in place. This is consistent with Generally Accepted Accounting Principles for regulated industries and the intent of the General Rate Schedule Provisions (GRSPs).

[Note: Consistent with the Partial Settlement of BPA's Rate Case which stipulated that detailed data would be embargoed for 12 months, the actual data used in the calculation has been purged from this version of the model. As a result, there are numerous DIV by Zero messages. This is simply a result of the equations remaining but the data used by these equations has been omitted.]
