SPOKANE, Wash., Sept. 01, 2023 (GLOBE NEWSWIRE) -- Avista (NYSE: AVA) has made annual rate adjustment filings with the utility commissions in Washington and Idaho that, if approved, will result in an increase in electric rates and decrease in natural gas rates in Washington, and increase natural gas rates in Idaho, effective November 1, 2023.

1. Wildfire Expense Balancing: increase of $3.3 million or 0.6%
2. Residential Exchange Program: increase of $1.1 million or 0.2%
3. Insurance Expense Balancing: increase of $0.1 million or 0.0%
4. Low Income Rate Assistance Program: increase of $7.6 million or 1.3%

3. Insurance Expense Balancing: increase of $10 thousand or 0.0%
   

Idaho Natural Gas Adjustment Filing

1. Purchased Gas Cost Adjustment: increase of $5.4 million or 5.0%
   

Purchased Gas Cost Adjustment (PGA) – Applicable to Washington and Idaho Natural Gas
PGA requests are typically filed annually to balance the actual cost of wholesale natural gas purchased by Avista to serve customers with the amount presently included in customer’s 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.

These rate adjustments are driven primarily by higher wholesale natural gas prices observed during this past winter, which were well above the amounts included in rates. That was partially offset by lower forward wholesale natural gas prices for the upcoming PGA year. For Washington, the reduction is largely driven by a reduction in the current seasonal surcharge amortization rate in effect for residential customers, as approved by the Washington Utilities and Transportation Commission last Fall.

Wildfire Balancing – 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 increase proposed today reflects the higher level of expense incurred above the amount presently included in customer’s 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 credit in their monthly electric rates. Due to fluctuations in usage, Avista rebated to customers a level of benefits that was higher than the level of benefits received from BPA. Through this filing Avista is seeking to slightly decrease the level of benefits provided to qualifying customers in order to return the over-rebated balance.

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. While this program has historically provided lump-sum grants to customers, LIRAP will transition to an income-based bill discount – in addition to offerings to help customers manage their past due balances, or arrearages – on October 1, 2023. This new bill assistance model will expand LIRAP to serve more customer than ever before, therefore requiring increased funding to do so. The rate increase proposed reflects this higher level of funding needed.

Insurance Balancing – 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 lower expense incurred for natural gas customers, compared to the amount presently included in customer’s rates.
