Peninsula Light Company

What This Utility Data Tells You

Peninsula Light Company is a member-owned electric cooperative operating in Washington under EIA identifier 14668. It reports service to approximately 35,429 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 18 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 Peninsula Light Company customer experienced 179.5 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 1.34 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 106.0 minutes — the gap between that figure and the headline 179.5 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Peninsula Light Company, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 77.0 to 179.5 minutes, which may reflect either worsening weather exposure or delayed grid modernization. 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.
