In 2023, the average PUD No 1 of Grays Harbor County customer experienced 256.0 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report.
