Runestone Electric Assn

What This Utility Data Tells You

Runestone Electric Assn is a member-owned electric cooperative operating in Minnesota under EIA identifier 16368. It reports service to approximately 15,239 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 41 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 Runestone Electric Assn customer experienced 56.1 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. Over the same period, SAIFI (outage events per customer) was 0.58, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 56.1 minutes, and the spread against the headline 56.1 indicates how much weather, versus routine infrastructure, drove the outage total.

Runestone Electric Assn has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that window, SAIDI moved from 134.8 down to 56.1 minutes, a trend worth noting for anyone weighing capital investment outcomes.
