Fitchburg Gas & Elec Light Co is an investor-owned utility operating in Massachusetts under EIA identifier 6374. It reports service to approximately 10,977 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 12 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.
In 2023, the average Fitchburg Gas & Elec Light Co customer experienced 1014.9 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. SAIFI, the average number of outage events per customer, was 2.45 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 90.4 minutes; the difference from the headline 1014.9 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Fitchburg Gas & Elec Light Co, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 256.8 to 1014.9 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
