Average price of electricity to ultimate consumers represents the cost per unit of electricity sold and is calculated by dividing electric revenue from ultimate consumers by the corresponding sales of electricity.
The average price of electricity to ultimate consumers reported in this publication by sector represents a weighted average of consumer revenue and sales, and does not equal the per kWh rate charged by the electric power industry participant to the individual consumers.

- SAIDI without major event days: 18.8 minutes for each customer in 2024, 19 minutes.
- SAIFI with major event days: 0.47 interruptions for each customer in 2024.

|---|---|---|---|---|
| SAIDI with major event days (minutes per customer per year) | 39.2 | 85.7 | 166.7 | 184.5 |

The utility reported these figures to EIA with the IEEE 1366 standard. Methods differ between utilities. What SAIDI and SAIFI mean
For utilities using the IEEE method, a Major Event Day is any day that exceeds a daily SAIDI threshold called Tmed. Tmed is a duration statistic calculated from daily SAIDI values from the past five years. For utilities not using IEEE methods, Major Events are self-determined by the reporting utility.
