Grady Electric Membership Corp

What This Utility Data Tells You

Grady Electric Membership Corp is a member-owned electric cooperative operating in Georgia under EIA identifier 7450. It reports service to approximately 20,389 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 23 ZIP codes. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.

In 2023, the average Grady Electric Membership Corp customer experienced 719.2 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That exceeds the 120–180 minute national benchmark by a wide margin, a pattern often tied to severe weather exposure, older infrastructure, or longer repair windows. The SAIFI figure, which tracks average outage events per customer, came in at 4.82 for the same period, meaning customers statistically saw about 5 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 503.0 minutes, and the spread against the headline 719.2 indicates how much weather, versus routine infrastructure, drove the outage total.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Grady Electric Membership Corp, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 187.4 to 719.2 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
