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. 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 Peninsula Light Company customer experienced 179.5 minutes of power interruptions, a metric called SAIDI (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. 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. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 106.0 minutes, and the spread against the headline 179.5 indicates how much weather, versus routine infrastructure, drove the outage total.

Peninsula Light Company 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 span, SAIDI rose from 77.0 to 179.5 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
