What mid-pack Powder River Energy Corp filings show

Powder River Energy Corp is a member-owned electric cooperative operating in Wyoming under EIA identifier 19156. It reports service to approximately 26,558 customer accounts and generated about $0.16 billion in annual electric revenue, with a service footprint spanning 48 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 Powder River Energy Corp customer experienced 205.5 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. The SAIFI figure, which tracks average outage events per customer, came in at 1.40 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 205.5 minutes; the difference from the headline 205.5 shows how much of the outage total came from weather rather than everyday grid issues.

With 4 consecutive years of EIA data (2020–2023), Powder River Energy Corp's reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 286.1 to 205.5 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.

Price vs. reliability

Where Powder River Energy Corp sits on price vs. reliability

Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Powder River Energy Corp charges more per customer than 99% of them, and is more reliable (lower SAIDI) than 45% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
