Avista Corp Electricity Rate per kWh (2024 EIA Data)
Investor Owned|EIA utility 20169|Washington + 2 more|Bundled
In 2024, Avista Corp's residential customers paid an average of 11.87 cents per kWh: $316 million of revenue over 2.66 million MWh of sales across 246,055 bundled residential customers, as reported to EIA on Form 861.
How the 11.87c figure is calculated
11.87c/kWh = $315,779k revenue / 2,661,059 MWh x 100. This is EIA's average realised price for 2024: everything Avista Corp billed its residential customers (energy, delivery, fuel and rider charges, fixed charges) divided by the kilowatt-hours it sold. It is not a tariff rate, and a 2024 annual average will differ from a current bill. For a 1,000 kWh month at this average, the energy cost works out to about $119 before taxes.
About Avista Corp's 2024 electricity prices
Avista Corp is an investor-owned electric utility that reports to the U.S. Energy Information Administration under utility number 20169. In 2024 it served 246,055 bundled residential customers in Washington (its largest state of 3), and its average realised residential price was 11.87 cents per kWh: $316 million of residential revenue divided by 2.66 million MWh of residential sales.
Across the other sectors, Avista Corp's 2024 average prices were 12.77 cents for commercial customers (27,249 accounts) and 7.80 cents for industrial customers (811 accounts). Industrial customers paid 4.07 cents less per kWh than households, a 34% discount that is typical of high-volume, high-voltage service.
Within Washington, Avista Corp ranked number 4 of 40 utilities with bundled or delivery service by residential accounts served (246,055) and accounted for 6.89% of the state's residential electricity sales in 2024, measured in MWh sold or delivered rather than in customers. The state-wide average realised residential price in 2024, computed from the same EIA file, was 11.90 cents per kWh, so Avista Corp's customers paid 0.03 cents below the Washington average (-0.3%). For context, EIA's latest monthly figure for Washington is 14.91 cents per kWh (June 2026, Electric Power Monthly); that is a different, more recent measure across all utilities and is not directly comparable with a 2024 annual average.

On the grid side it operates in the WECC NERC region, and reported generation, transmission, buying transmission, distribution, wholesale marketing, and bundled as its activities. Balancing authority code: AVA.

Final 2024 file f8612024.zip (released 3 December 2025) from the EIA-861 detailed data files.

Method: cents per kWh = revenue (thousand dollars) divided by sales (megawatthours), times 100. Customer counts, sales and revenue are the utility's own annual survey responses by state and sector. Bundled = energy plus delivery from one utility; delivery-only = the wires charge for customers who buy energy from a competitive supplier; energy-only = a competitive supplier's energy charge without delivery. County lists come from the EIA-861 Service Territory file; territory centroids used for "nearby utilities" are unweighted means of Census 2023 county centroids.
