Town of Sterling - (MA) is a municipally-owned utility operating in Massachusetts under EIA identifier 18087. It reports service to approximately 4,077 customer accounts and generated about $0.01 billion in annual electric revenue. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average Town of Sterling - (MA) customer experienced 3.2 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. Over the same period, SAIFI (outage events per customer) was 0.06, putting the typical customer at roughly 0 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 3.2 minutes, the gap between that figure and the headline 3.2 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), Town of Sterling - (MA)'s reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 54.2 to 3.2 minutes across that span, a direction regulators and prospective customers tend to watch closely. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Town of Sterling - (MA)'s other reported years.
