Cobb Electric Membership Corp

What This Utility Data Tells You

Cobb Electric Membership Corp is a member-owned electric cooperative operating in Georgia under EIA identifier 3916. It reports service to approximately 220,910 customer accounts and generated about $0.43 billion in annual electric revenue, with a service footprint spanning 31 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 Cobb Electric Membership Corp customer experienced 37.4 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. The SAIFI figure, which tracks average outage events per customer, came in at 0.89 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 33.0 minutes; the difference from the headline 37.4 shows how much of the outage total came from weather rather than everyday grid issues.

With 4 consecutive years of EIA data (2020–2023), Cobb Electric Membership Corp's reliability record can be judged on trend rather than one isolated year. Over that window, SAIDI moved from 375.6 down to 37.4 minutes, a trend worth noting for anyone weighing 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 Cobb Electric Membership Corp's other reported years.
