Vermont Electric Cooperative, Inc is a member-owned electric cooperative operating in Vermont under EIA identifier 19791. It reports service to approximately 40,835 customer accounts and generated about $0.09 billion in annual electric revenue, with a service footprint spanning 80 ZIP codes. Cooperative ownership means the utility is run for the benefit of the ratepayer-members who elect its board, rather than for shareholder returns, which can shift how rate and investment decisions get made.
In 2023, the average Vermont Electric Cooperative, Inc customer experienced 486.3 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. The SAIFI figure, which tracks average outage events per customer, came in at 2.25 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 204.3 minutes, and the spread against the headline 486.3 indicates how much weather, versus routine infrastructure, drove the outage total.
With 4 consecutive years of EIA data (2020–2023), Vermont Electric Cooperative, Inc's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 158.4 to 486.3 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
