Kauai Island Utility Cooperative Electricity Rate per kWh (2024 EIA Data)
Cooperative|EIA utility 10071|Hawaii|Bundled
In 2024, Kauai Island Utility Cooperative's residential customers paid an average of 41.29 cents per kWh: $80 million of revenue over 193,728 MWh of sales across 30,109 bundled residential customers, as reported to EIA on Form 861.
How the 41.29c figure is calculated
41.29c/kWh = $79,983k revenue / 193,728 MWh x 100. This is EIA's average realised price for 2024: everything Kauai Island Utility Cooperative 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 $413 before taxes.

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.
