What This Utility Data Tells You

City of Westfield - (MA) is a municipally-owned utility operating in Massachusetts under EIA identifier 20481. It reports service to approximately 18,311 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 8 ZIP codes. Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.

In 2023, the average City of Westfield - (MA) customer experienced 421.0 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. Over the same period, SAIFI (outage events per customer) was 3.98, putting the typical customer at roughly 4 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 71.3 minutes, and the spread against the headline 421.0 indicates how much weather, versus routine infrastructure, drove the outage total.

With 4 consecutive years of EIA data (2020–2023), City of Westfield - (MA)'s reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 363.3 to 421.0 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
