What short-outage City of Norwood - (MA) filings show
City of Norwood - (MA) is a municipally-owned utility operating in Massachusetts under EIA identifier 13839. It reports service to approximately 15,779 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 6 ZIP codes. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.
In 2023, the average City of Norwood - (MA) customer experienced 62.7 minutes of power interruptions, a measure known as SAIDI, or 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 0.96 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 46.0 minutes, the gap between that figure and the headline 62.7 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 3 years of continuous reporting (2021–2023) for City of Norwood - (MA), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 108.1 to 62.7 minutes across that span, a direction regulators and prospective customers tend to watch closely.
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. Not a measure of electricity rates or customer service, which this portal does not track.
