WebOct 1, 2024 · As such, CAIDI can be misleading because it can stay the same even when the SAIDI and SAIFI values decrease and there is an improved customer experience. For example, if a utility improves its grid and decreases its SAIDI to three hours and its SAIFI to one outage, the utility’s CAIDI value would be 3 (three hours per outage).
