YOU ARE HEREBY NOTIFIED that on June 30, 1995 The Washington Water Power Company (Water Power; Company) in Case No. WWP-E-95-4 filed an Application with the Idaho Public Utilities Commission (Commission) proposing a revision to the Company’s Electric Tariff Schedule 66—Temporary Power Cost Adjustment—Idaho.  Water Power requests that the Commission approve a $2,258,000, 2.43% surcharge to Water Power’s Idaho customers.(footnote: 1)  The surcharge is being requested as a result of the “trigger” being reached and exceeded in Water Power’s Power Cost Adjustment (PCA) balancing account as established in Case No. WWP-E-88-3, Order No. 22816 issued October 31, 1989, extended in Case No. WWP-E-93-3, Order No. 24874, and extended and modified in Case No. WWP-E-94-4, Order No. 25637.  Since the inception of the PCA in October 1989, the Company’s customers in the state of Idaho have received two rebates and two surcharges:
$2,247,000 (2.45%) rebate beginning May 1, 1990
$2,314,000 (2.51%) rebate beginning May 1, 1991
$2,272,000 (2.59%) surcharge beginning November 1, 1992
$2,239,000 (2.54%) surcharge beginning January 1, 1995
Water Power is proposing that the requested surcharge become effective September 1, 1995, and expire August 31, 1996.  
The present PCA rate adjustment mechanism, as more particularly described in Order No. 25637, is designed to recover/rebate abnormal net power supply expenses incurred by the Company.  The PCA mechanism tracks changes in the Company’s power supply costs associated with abnormal weather and streamflows.  (The weather related portion of the PCA tracks 100% of the variation in hydro generation from the hydro generation authorized.  It also tracks 80% of the variation in secondary prices from those authorized, and the related variation in thermal generation.)  The PCA is also designed to recover contract costs incurred pursuant to the Public Utility Regulatory Policies Act of 1978 (PURPA) and the related implementing rules and regulations of the Federal Energy Regulatory Commission (FERC) beyond the level included in the Company’s general revenue requirement.  PURPA contract costs are the result of the Company’s federally mandated obligation to purchase the output of qualifying small power and cogeneration facilities and, therefore, are largely outside the control of Water Power.  (The PCA tracks 100% of the changes in costs associated with PURPA contracts.)  The Company is allowed to record the difference between actual power supply costs and the level of those costs authorized by the Commission.  When the total difference in costs exceed $2.2 million, the Company may request authority to implement a surcharge or rebate.  As reflected in the Company’s Application, the $2.2 million trigger was reached and exceeded at the end of April 1995.  
As represented by Water Power, the net deferral of $2,258,000 in the Company’s PCA balancing account is the result of the sum of (1) total weather-related deferrals of $2,161,000 in the surcharge direction and (2) PURPA tracker deferrals of $97,000 in the surcharge direction.  The net deferral amount includes a true-up or correction for prior months of $56,000 in the surcharge direction.  The weather-related and PURPA tracker deferrals are more particularly described as follows:
1.  Weather-related deferrals
As reported by the Company, the weather-related surcharge results primarily from low streamflow conditions from September 1994 through April 1995.  These low streamflow conditions resulted in lower than normal generation from the Company’s hydroelectric plants.  The Company had to operate more expensive thermal generation plants or purchase power from other utilities to meet customer loads, which caused the Company’s power supply costs to be higher than the level authorized by the Commission.  
The Company reports that in September 1994 the actual hydro generation was 194 average megawatts below authorized and in April 1994 was 174 average megawatts below authorized.  For the entire period, hydro generation was 672 average megawatts below authorized.  Natural flow for the Spokane River where Water Power owns and operates six hydroelectric projects (18% of Company system hydro capability) during the period September 1994 through April 1995 was 134% of normal.  During this time period, however, the Company reports that natural flow was below normal four out of the eight months, and for the months of September 1994 through November 1994 was 75% of normal.  Natural flow for the Clark Fork River where the Company’s two largest electric projects are located (82% of Company system hydro capability) during the same period was 94% of normal, but was below normal six out of the eight months and for the months of September 1994 through January 1995 was 69% of normal.
The Company reports that actual weighted average secondary prices were significantly above those authorized for the months of September 1994 through January 1995 when natural flows were below normal, thus causing Water Power to purchase power at prices higher than authorized.  In April 1995, actual weighted average secondary prices were below authorized prices when flows again dropped below normal, resulting in a level of secondary sales significantly below authorized.
2.  PURPA tracker deferrals
Workpapers filed by the Company show deferrals for the PURPA tracker in the rebate direction for the months of September 1994 through November 1994 and deferrals in the surcharge direction for the months of December 1994 through April 1995.  These deferrals, the Company reports were due mainly to Water Power’s contract with the City of Spokane for energy purchased from their Upriver Hydro Project located on the Spokane River.
The mechanics of a surcharge are well defined in the Commission’s 1989 PCA Order.  The surcharge is to take place over a period of 12 months at the end of which time Water Power is to file a report indicating the total amount collected.  Any existing difference is to be credited (debited) to the balancing account.  The surcharge is to be spread to all customer classes on a uniform percentage basis and recovered on the energy component of each schedule except for lighting schedules where recovery is to be on a flat rate uniform percentage basis.  PCA related rate changes are limited to no more than two consecutive surcharges or rebates during any 12-month period, July 1 to June 30, and the annual rate change during any 12-month period is limited to 5%.
Under the Company’s proposal in this case, the monthly energy charges of the individual rate schedules are to be increased by the following amounts:

.075¢/kWh
.143¢/kWh
Schedules 31 & 32 (pumping)
.152¢/kWh
.128¢/kWh
.281¢/kWh
Flat rate charges for Company-owned or customer-owned street lighting and area lighting service are to be increased an additional 2.434% over the present 2.54% for an overall proposed Schedule 66 surcharge of 4.971%.  The effect of the surcharge on an average Schedule 1 residential customer using 1,071 kilowatt hours per month would be an increase of $1.19 per month for a total effective proposed Schedule 66 surcharge of $2.46 per month.
YOU ARE FURTHER NOTIFIED that the Commission has reviewed the Company’s Application, proposed tariff and supporting testimony.  The Commission has preliminarily found that the public interest regarding implementation of the proposed revisions to electric Tariff Schedule No. 66 may not require a hearing to consider the issues presented and that it may be appropriate to process the Company’s Application under Modified Procedure, i.e., by written submission rather than by hearing.  Reference Commission Rules of Procedure IDAPA 31.01.01.201 et seq.
YOU ARE FURTHER NOTIFIED that the Commission will not hold a hearing in this proceeding unless it receives written protests or comments opposing the use of modified procedure and stating why Modified Procedure should not be used.  Reference IDAPA 31.01.01.203.
YOU ARE FURTHER NOTIFIED that the deadline for filing written comments or protests with respect to the Company’s Application and use of Modified Procedure in Case No. WWP-E-95-4 is Friday, August 18, 1995.  Persons desiring a hearing must specifically request a hearing in their written protests or comments.
YOU ARE FURTHER NOTIFIED that if no protests or comments are received within the deadline, the Commission may consider the matter and enter its Order without a hearing.  If protests or comments are filed within the deadline, the Commission will consider them and may set the matter for hearing or may decide the matter and issue its Order on the basis of the written positions before it.  Reference IDAPA 31.01.01.204.
YOU ARE FURTHER NOTIFIED that the Application and proposed revisions to Water Power’s Electric Schedule No. 66 tariff together with the Company’s supporting testimony have been filed with the Commission and are available for public inspection during regular business hours at the Commission office and at the Idaho offices of The Washington Water Power Company.

FOOTNOTES
1:
 As proposed by the Company, the increase will not affect recently acquired customers in the Sandpoint area.  The Company began serving those customers on January 1, 1995.  At that time, the balance in the PCA deferral account was $1,360,000 of the $2,258,000 surcharge proposed in this filing.
