Hart Electric Member Corp is a member-owned electric cooperative operating in Georgia under EIA identifier 8210. It reports service to approximately 39,140 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 20 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 Hart Electric Member Corp customer experienced 97.8 minutes of power interruptions, a measure known as SAIDI, or 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 1.30 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 79.2 minutes, and the spread against the headline 97.8 indicates how much weather, versus routine infrastructure, drove the outage total.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Hart Electric Member Corp, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 750.9 to 97.8 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes. 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 Hart Electric Member Corp's other reported years.
