Requests would result in lower electric prices effective Oct. 1, 2022 and lower natural gas prices Nov. 1, 2022.

 

SPOKANE, Wash. – July 29, 2022, 1:05 p.m. PDT:  Avista (NYSE: AVA) has made annual rate adjustment filings with the Idaho Public Utilities Commission (IPUC or Commission) that if approved, are designed to decrease overall electric revenues by approximately $12.0 million or 4.7% effective Oct. 1, 2022 and decrease overall natural gas revenue by approximately $0.1 million or 0.2% effective Nov. 1, 2022. These annual filings have no impact on Avista’s earnings.

Electric Adjustment Filings

Four annual electric adjustments were filed, that if approved, are designed to change overall electric revenues effective Oct. 1, 2022 as follows:

 

  1. Power Cost Adjustment (PCA): a decrease of approximately $3.1 million or 1.2%
  2. Fixed Cost Adjustment (FCA): a decrease of approximately $5.1 million or 2.0%
  3. Electric Energy Efficiency: a decrease of approximately $3.7 million or 1.4%
  4. Bonneville Power Administration Residential Exchange (ResEx) Program: a decrease of approximately $0.1 million or 0.1%

 

Natural Gas Adjustment Filing

The natural gas adjustment request is the annual natural gas FCA. If approved, Avista’s request is designed to decrease overall natural gas revenues by approximately $0.1 million or 0.2% effective Nov. 1, 2022.

 

Customer Bills Resulting from these Filings

If the electric PCA, FCA, energy efficiency and ResEx filings are approved, residential electric customers in Idaho using an average of 892 kilowatt hours per month would see their monthly bills decrease from $86.29 to $82.19, a decrease of $4.10 per month, or approximately 4.8%. The proposed electric rate change would be effective Oct. 1, 2022.

 

The net effect, on an annual revenue basis, for the requested electric rate changes by rate schedule are as follows:

 

Residential Service – Schedule 1                         -5.0%

General Service – Schedules 11 & 12                   -6.0%

Large General Service – Schedules 21 & 22          -4.3%

Extra Large General Service – Schedule 25           -3.2%

Extra Large General Service – Schedule 25P         -3.5%

Pumping Service – Schedules 31 & 32                 -4.9%

Street & Area Lights – Schedules 41-49                -1.2%

Overall                                                                -4.7%

 

If the natural gas FCA filing is approved, residential natural gas customers in Idaho using an average of 63 therms per month would see their monthly bills decrease from $62.06 to $61.73, a decrease of $0.33 per month, or approximately 0.5%. The proposed natural gas rate change would be effective Nov. 1, 2022.

 

The net effect, on a revenue basis, for the requested natural gas rate change by rate schedule are as follows:

 

General Service – Schedule 101                          -0.5%

Large General Service – Schedules 111 & 112       1.2%

Interruptible Service – Schedules 131 & 132           0.0%

Transportation Service – Schedule 146                  0.0%

Overall                                                                -0.2%

 

Power Cost Adjustment (PCA)

The PCA is an annual rate adjustment made to reflect the difference between the actual cost of generating and purchasing electric power to serve customers and the cost currently included in customer rates. Over the last year, power supply costs were higher than those included in retail rates due to higher wholesale electric and natural gas prices. However, the higher power supply costs were more than offset by the expiration of the prior year’s surcharge, resulting in an overall rate decrease.

 

Fixed Cost Adjustment (FCA)

The electric and natural gas FCA is a mechanism designed to break the link between a utility’s revenues and customers’ energy usage. Avista’s actual revenue, based on kilowatt hour or therm sales, will vary, up or down, from the level included in a general rate case and approved by the Commission. This could be caused by changes in weather, energy conservation or other factors. Under the FCA, Avista’s revenues are adjusted each month based on the number of customers. The annual difference between revenues based on sales and the number of customers is surcharged or rebated to customers beginning in the following year.

 

The proposed FCA rate adjustments in 2022 are primarily driven by variations in 2021 customer usage related to weather and the COVID-19 pandemic where a higher level of residential customer usage was partially offset by a lower level of non-residential customers usage. The FCA mechanisms do not apply to Avista’s Electric Extra Large General and Street Lighting Service Schedules, nor to its Natural Gas Interruptible and Transportation Service Schedules.

 

Energy Efficiency Adjustment

The energy efficiency adjustment is related to the funding of Avista’s electric energy efficiency programs. This adjustment aligns the amount that is collected in customer rates with the actual costs to run and deliver the programs. Avista’s energy efficiency programs are designed to provide a financial incentive or rebate for cost-effective energy efficiency measures. The Commission approves the amount of funding for these important programs through a portion of energy rates. The rate reduction proposed reflects the lower level of funding needed to operate the programs in the coming year.

Residential Exchange Adjustment

The Residential Exchange Program provides a share of the benefits of the federal Columbia River power system to the residential and small farm customers of the investor-owned utilities in the Pacific Northwest, including Avista. Avista applies the benefits it receives, which typically fluctuate from year to year, to customers as a credit in their monthly electric rates. Due to fluctuations in usage, Avista rebated to customers a level of benefits that was slightly lower than the level of benefits received from BPA. Through this filing Avista is seeking to slightly increase the level of benefits provided to qualifying customers in order to return the under-rebated balance.

 

Rate Application Procedure

Avista’s applications are proposals, subject to public review and a Commission decision. Copies of the applications are available for public review at the offices of both the Commission and Avista, and on the Commission’s website (www.puc.idaho.gov). Customers may file with the Commission written comments related to Avista’s filings.
