Black Hills Electric Coop, Inc

What This Utility Data Tells You

Black Hills Electric Coop, Inc is a member-owned electric cooperative operating in South Dakota under EIA identifier 1769. It reports service to approximately 11,185 customer accounts and generated about $0.02 billion in annual electric revenue, with a service footprint spanning 23 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 Black Hills Electric Coop, Inc customer experienced 163.8 minutes of power interruptions, a measure known as SAIDI, or 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. Over the same period, SAIFI (outage events per customer) was 0.78, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 87.8 minutes, the gap between that figure and the headline 163.8 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Black Hills Electric Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 222.6 to 163.8 minutes across that span, a direction regulators and prospective customers tend to watch closely.
