What This Utility Data Tells You

City of Grand Haven - (MI) is a municipally-owned utility operating in Michigan under EIA identifier 7483. It reports service to approximately 14,955 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 1 ZIP code.

In 2023, the average City of Grand Haven - (MI) customer experienced 158.7 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. SAIFI, the average number of outage events per customer, was 1.45 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 28.9 minutes, and the spread against the headline 158.7 indicates how much weather, versus routine infrastructure, drove the outage total.

With 4 consecutive years of EIA data (2020–2023), City of Grand Haven - (MI)'s reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 73.2 to 158.7 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
