City of Grand Island - (NE) is a municipally-owned utility operating in Nebraska under EIA identifier 40606. It reports service to approximately 26,744 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 3 ZIP codes.

In 2023, the average City of Grand Island - (NE) customer experienced 11.9 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. The SAIFI figure, which tracks average outage events per customer, came in at 0.43 for the same period, meaning customers statistically saw about 0 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 9.4 minutes, the gap between that figure and the headline 11.9 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), City of Grand Island - (NE)'s reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 27.1 to 11.9 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
