Avista Makes Annual Price Adjustment Requests in Washington

AVA

Avista filed annual rate adjustment requests with the Washington Utilities and Transportation Commission to align customer rates with actual incurred costs.
Approved filings would decrease natural gas rates by approximately 11.5% while leaving electric rates nearly unchanged with a 0.01% reduction.
The primary driver for the natural gas decrease is the Climate Commitment Act, which accounts for an 11% reduction, alongside lower supply & transportation costs.
Most residential natural gas customers using 61 therms monthly would see bills drop from $96.18 to $88.80, a decrease of roughly 7.7%.
Non-residential natural gas customers face larger decreases, including a 35.7% reduction for transportation service schedule 146 customers.
Residential electric customers using 925 kWh monthly would see a negligible bill decrease from $125.69 to $125.64, representing a 0.04% drop.
Electric adjustments include a 0.03% decrease for residential service but small increases for general service, large general service, extra large general service, & street lighting schedules.
Natural gas adjustments total $34.3 million in reductions, driven by $32.8 million from the Climate Commitment Act, $1.3 million from the Purchased Gas Cost Adjustment, & $0.1 million from insurance expense balancing.
The Climate Commitment Act adjustment reflects lower compliance costs & updated benefits from the sale of no-cost allowances allocated by the Washington Department of Ecology.
The Purchased Gas Cost Adjustment reflects lower wholesale natural gas prices during the past winter compared to previously approved levels.
Electric adjustments result in an overall decrease of approximately $20,000, offsetting a $0.5 million increase for the Clean Energy Implementation Plan with decreases from the Residential Exchange Program & insurance expenses.
