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 metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI — the average number of outage events per customer — was 1.40 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 205.5 minutes — the gap between that figure and the headline 205.5 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Powder River Energy Corp, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. 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. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.

Powder River Energy Corp had a SAIDI of 205.5 minutes in 2023, meaning the average customer experienced about 205 minutes of outages that year. This is near the national average.
Powder River Energy Corp is classified as a Cooperative serving Wyoming. Electric cooperatives are member-owned nonprofit utilities, typically serving rural areas.
SAIDI (System Average Interruption Duration Index) measures the average total minutes per year that a customer of Powder River Energy Corp experiences power outages. A lower SAIDI indicates better reliability. The national average is roughly 120-180 minutes per year, so comparing Powder River Energy Corp's SAIDI to that benchmark shows whether this utility is above or below average.
Powder River Energy Corp serves approximately 26,558 customers in Wyoming. Customer count can affect reliability metrics because larger utilities may face different infrastructure challenges compared to smaller ones.
Powder River Energy Corp has 4 years of reliability data (2020-2023). SAIDI has remained relatively stable over this period. Review the trend table above for year-by-year detail.
SAIDI "without major event days" (SAIDI nMED) excludes outages caused by hurricanes, ice storms, and other catastrophic weather events. It better reflects day-to-day infrastructure reliability rather than vulnerability to extreme weather. Both standard SAIDI and SAIDI nMED are shown in the reliability trend table above.
