5. Low Income Rate Assistance Program: increase of $6.7 million or 0.9%
   
   

A description of each of the rate adjustments is as follows:

Purchased Gas Cost Adjustment (PGA) – Applicable to Washington Natural Gas

PGA requests are filed annually to balance the actual cost of wholesale natural gas purchased by Avista to serve customers with the amount presently included in customer rates. Avista does not make a profit on, or markup, the wholesale cost of natural gas. PGAs ensure customers pay what Avista pays, dollar for dollar, only at a more predictable and stable rate throughout the year. About 55% of an Avista natural gas customer's bill is the combined cost of purchasing natural gas on the wholesale market and transporting it to Avista's system.

The proposed PGA reduction is largely driven by the wholesale cost of natural gas being lower than the amount currently included in customer rates.

Climate Commitment Act (CCA) – Applicable to Washington Natural Gas

The CCA, passed by the Washington State legislature and enacted into law in 2021, implements a cap-and-invest program designed to meet state emission reduction targets and reduce emissions by 95% of 1990 levels by 2050. Natural gas utilities must meet declining targets for greenhouse gas emissions (GHG) as compared to a baseline, which is the average emissions from 2015-2019. Beginning in 2023, natural gas utilities received no-cost emissions allowances to cover a portion of their GHG baseline, which 65% of the no-cost allowances had to be consigned to allowance auctions held by the Department of Ecology.

The amount of no-cost allowances provided to utilities decreases each year. Due to the timing of implementation of the CCA, the present CCA component of customers’ bills includes two years' worth of costs associated with compliance with the CCA, recovered over a one-year timeframe. In the Company’s filing, CCA compliance costs for the prior two-year period are replaced with the estimated cost of CCA compliance for 2026, resulting in an overall decrease for customers. 

Consignment of no-cost allowances to auction resulted in revenues back to the utility, which shall be used for the benefit of customers as determined by the Commission, including at minimum, eliminating any additional cost burden to low-income customers due to the implementation of the CCA. Locations connected to the natural gas system after July 25, 2021, are not eligible to receive any benefit from these revenues, according to state law.  The rate change proposed reflects the cost of compliance with the CCA.

Low Income Rate Assistance Program – Applicable to Washington Electric and Natural Gas

The Low Income Rate Assistance Program, or LIRAP, provides bill assistance to income eligible customers with a household income less than or equal to 200% Federal Poverty Level (FPL) or 80% Area Median Income (AMI), whichever is greater. This rate increase is necessary to support the continuation and expansion of all LIRAP components, which includes both an income-based bill discount as well as offerings intended to help customers manage their past due balances.

Insurance Balancing Account – Applicable to Washington Electric and Natural Gas

The Insurance Expense Balancing account tracks the difference in insurance expense incurred by Avista to the base level of expense approved by the Commission. The difference is rebated to, or collected from, customers annually. The rate changes proposed reflect the higher level of expense incurred for electric customers and slightly lower expense incurred for natural gas customers, as compared to the existing amount presently being collected in customers rates.

Wildfire Balancing Account – Applicable to Washington Electric

The Wildfire Expense Balancing account tracks the difference in wildfire expenses incurred by Avista to address the growing frequency of extreme and dangerous wildfires in Avista’s service territory to the base level of expense approved by the Commission. The difference is rebated to, or collected from, customers annually. The rate change reflects the level of expense incurred as compared to the existing amount being collected in customers rates.

Residential Exchange Program – Applicable to Washington Electric

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 reduction in their monthly electric rates. The benefit Avista will receive from BPA starting in October 2025 will result in a lower level of benefits than is currently being passed through to qualifying customers.

Clean Energy Implementation Plan – Applicable to Washington Electric

Avista’s Clean Energy Implementation Plan (CEIP) tariff recovers the costs associated with our clean energy transition. These costs include a “Named Communities Investment Fund” (NCIF), which helps assist with the equitable distribution of CEIP energy and non-energy benefits and reduction in burdens to vulnerable populations and highly impacted communities (Named Communities). In addition to the NCIF, this tariff recovers the costs for additional resources necessary for implementation of Avista’s CEIP and associated conditions to the CEIP.

Effect on Customer Bills

Natural Gas Customer Bills

Washington: If approved by the Commission, most residential natural gas customers in Washington using an average of 66 therms per month would see their monthly bills change from $95.97 to $86.84, a decrease of $9.13 per month, or approximately 9.5%, when compared to rates currently in effect.

The percentage change will vary by rate schedule, depending on when the customer’s meter was first installed at their premise, and how much energy a customer uses. If approved, natural gas customers could see the following rate adjustments:

Customers served on Transportation Service Schedule 146 procure their own wholesale natural gas and interstate pipeline transportation service. As such, those customers do not receive the effects of the reduction due to the PGA.  

Electric Customer Bills

Washington: If approved by the Commission, residential electric customers in Washington using an average of 945 kilowatt hours/month would see their monthly bills change from $123.42 to $126.69, an increase of $3.27/month, or approximately 2.6%.

The percentage change varies by rate schedule and is dependent upon how much energy customers on the respective rate schedules use. If approved, residential electric customers would see the following rate adjustments:
