What mid-pack Town of Wallingford - (CT) filings show

In 2023, the average Town of Wallingford - (CT) customer experienced 110.3 minutes of power interruptions, the industry-standard SAIDI metric (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. The SAIFI figure, which tracks average outage events per customer, came in at 0.46 for the same period, meaning customers statistically saw about 0 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 45.2 minutes, and the spread against the headline 110.3 indicates how much weather, versus routine infrastructure, drove the outage total.
With 4 consecutive years of EIA data (2020–2023), Town of Wallingford - (CT)'s reliability record can be judged on trend rather than one isolated year. SAIDI has increased from 60.7 to 110.3 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide.
