  3. What is a Formula Rate? • A standard Rate is a fixed charge set in a regulatory process through a rate case • The fixed rates do not change unless another rate case is filed • A formula rate is a fixed method for calculating a rate based upon set inputs • The charges to customer update annually • Data input comes from public sources (Form 1) • Recalculation of the charges is done pursuant to a set of protocols

  4. Revenue Requirements The sum of the following: • Return on Equity (Rate Base * Rate of Return) • O&M • Depreciation Expense • Taxes other than income • Income Taxes

  5. Westar’s Formula Rate • Revenue Requirements used for billing is for a projected Test Year • Changes in costs are projected in all five components of the formula • A “True-up” calculation is done each year to compare the Actual Rev. Req. to the projected • Any refund or surcharge is an adjustment to the Rev. Req. for the next Projected Period • Minimizes work by not having to do annual refunds or surcharges

  6. Posting & Review Time Line Post Projected R.R for the next Rate Year Second Customer Meeting First Customer Meeting Jun. 23 Apr. 15 Jun. 15 Oct. 22 Oct. 30 Oct. 15 Jul. 15 Post Actual R.R from previous yr Start of the next Rate Year Form 1 Released Start of Rate Year Jan. 1 Jan. 1 You are here!

  8. Other Issues • The True-up amount is based upon the results of the TFR effective June 1, 2008 (per settlement in ER08-396) • Rev. Req. is without any “true-up” value from a previous period (footnote E, TU tab) • This year’s calculation is still part of the transition • Format of June 2008 formula is different from current one • Historic period to a projected period • Change in “Rate Year” from 12 months ending May to calendar year period

  9. Formula Rate Changes • Since October, 2008 the following two Dockets were approved that affect the formula • ER08-777/ER08-396 – Storm Damage Amortization • Compliance filing modifying footnote S, Actual Gross Revenue Requirement tab. • ER09-481 – Ministerial Filing to correct several footnote and line description errors. • Additional footnote errors were discovered in the update process • A subsequent filing is being looked at in the next several months .

  10. Protocols • Specify “how” the formula works • Gives specific rights to Customers • Review input • Point out input errors • Procedures to handle disputes • Posting – Westar’s OASIS is changing!
