What short-outage Town of Braintree - (MA) filings show

Town of Braintree - (MA) is a municipally-owned utility operating in Massachusetts under EIA identifier 2144. It reports service to approximately 16,752 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 7 ZIP codes.

In 2023, the average Town of Braintree - (MA) customer experienced 5.8 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). 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 0.10 for the same period, meaning customers statistically saw about 0 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 5.8 minutes, the gap between that figure and the headline 5.8 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), Town of Braintree - (MA)'s reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 3.9 to 5.8 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
