- Avista Corp reported an average residential price of 11.62¢ per kWh across its bundled residential customers in the 2024 EIA Form 861 release.

- What is the average electricity bill for Avista Corp customers?
- Dividing reported residential sales by residential customers gives about 10,578 kWh per customer per year. At the reported average price that implies roughly $1,229 a year, or about $102 a month. This is RateWatt's arithmetic on two EIA columns, not a figure EIA publishes.
- Who owns Avista Corp?
