Thousands of customers served by Peninsula Light Company experienced a widespread power outage across Gig Harbor, the Key Peninsula, and nearby communities in Pierce County, Washington, on Friday, October 16, 2026.
The electricity disruption affected a large portion of Peninsula Light’s service territory after an issue developed at Tacoma Public Utilities’ Pearl Street substation. Because Peninsula Light receives electricity through Tacoma Power’s transmission lines, the problem also affected customers across the peninsula.
Local reports indicated that approximately 36,000 Peninsula Light customers were affected at one point during the incident. The outage occurred alongside a separate disruption affecting customers in Tacoma, University Place, and Ruston.
The widespread interruption left residents and businesses without electricity as utility crews worked to investigate the problem and restore service.
Peninsula Light initially reported that there was no confirmed restoration estimate while crews gathered information. Later updates indicated that the utility had been cleared to begin restoring power to most affected areas.
By Friday afternoon, Peninsula Light had reported that electricity had been restored to its customers. Local news reports also confirmed that power had returned across the affected communities.
What Happened During the Peninsula Light Power Outage?
The widespread outage was reported on Friday morning, October 16, as customers across Peninsula Light Company’s service territory experienced interruptions to their electricity supply.
Peninsula Light announced the territory-wide outage at approximately 11:30 a.m. The utility subsequently identified an issue at Tacoma Public Utilities’ Pearl Street substation as the problem affecting the regional electricity network.
According to local reporting, the substation issue disrupted power delivery to a broad area, including communities served by Peninsula Light.
The utility initially said that crews and staff were gathering details about the interruption. At that stage, the company had not provided a confirmed cause beyond the reported issue involving Tacoma Power’s infrastructure or a definite restoration time.
The outage affected a substantial number of customers simultaneously, making it difficult to determine the full impact immediately.
As more information became available, Peninsula Light continued communicating with members while working with Tacoma Public Utilities to restore electricity safely.
Pearl Street Substation Issue Linked to the Outage
The outage was connected to a reported problem at Tacoma Public Utilities’ Pearl Street substation in Tacoma.
Peninsula Light relies on Tacoma Power’s transmission lines to bring electricity into its service territory. Consequently, a significant problem affecting that transmission infrastructure can interrupt power to many Peninsula Light customers at once.
A substation is an important part of the electrical grid. It helps manage voltage and direct electricity through the network that supplies homes, businesses, and other facilities.
When a problem affects critical transmission equipment, the consequences can extend beyond the immediate location of the fault.
In this case, the disruption crossed utility service boundaries, affecting Peninsula Light customers in addition to customers served directly by Tacoma Public Utilities.
Although the Pearl Street substation issue was identified in local reporting, the precise technical failure responsible for the October 16 incident was not established in the initial reports.
It is therefore important to distinguish the reported infrastructure problem from any unconfirmed explanation of what caused it.
How Many Customers Were Affected by the Peninsula Light Outage?
Approximately 36,067 Peninsula Light customers were reported to be affected at one point during the October 16 outage, according to updates carried by local news outlets.
The incident was part of a broader regional interruption that also affected Tacoma Public Utilities customers.
Across both utility systems, reports placed the combined impact at nearly 50,000 customers during the outage.
These figures represent reported customer impacts at particular times rather than a final count of everyone who experienced an interruption. Outage totals changed as utilities gathered information and electricity restoration progressed.
The outage was especially significant because Peninsula Light serves communities spread across Gig Harbor, the Key Peninsula, and nearby islands.
A disruption affecting a major transmission connection can have a much wider impact than a fault affecting a single neighborhood or local distribution line.
For residents, the loss of electricity affected normal household activities, while businesses faced possible interruptions to communications, payment systems, refrigeration, and other essential operations.
Areas Affected by the Peninsula Light Power Outage
The October 16 incident affected customers across multiple communities in Pierce County, Washington.
Reported areas included:
- Gig Harbor: Customers across the city and surrounding communities experienced power interruptions.
- Key Peninsula: The widespread outage affected Peninsula Light customers throughout parts of the peninsula.
- Fox Island: The island is among the communities served by Peninsula Light.
- Raft Island: Customers in the utility’s wider service territory were potentially affected by the regional interruption.
- Herron Island: The island is also within the communities associated with Peninsula Light’s service area.
The outage occurred alongside interruptions reported in Tacoma, University Place, and Ruston, where Tacoma Public Utilities customers were also affected.
Not every home or business in these communities necessarily lost electricity. The impact on individual properties depended on the affected electrical circuits and the progress of restoration.
Customers who continue to experience an interruption should check Peninsula Light’s official outage information for the latest details about their particular location.
Peninsula Light Restoration Update
Peninsula Light worked with Tacoma Public Utilities as the utility investigated the problem and prepared to restore service.
In its official alerts, Peninsula Light reported that the territory-wide outage began at approximately 11:30 a.m. on October 16. A subsequent update at approximately 12:40 p.m. stated that the company had been cleared to begin the restoration process for most areas.
The utility explained that other areas would come back online after the necessary patrols were completed.
Local news reports subsequently indicated that power had been restored to Peninsula Light customers.
KIRO 7 News also reported that electricity had been restored following the widespread outage affecting nearly 50,000 customers across Pierce County.
Although the broad interruption was reported to have been resolved, customers should not assume that every individual service issue has necessarily disappeared. A separate local fault or a continuing problem at a particular property may require additional attention.
Anyone whose home or business remains without electricity should report the outage directly to Peninsula Light and check the utility’s current outage information.
Why Did the Tacoma Outage Affect Peninsula Light Customers?
Peninsula Light Company’s electricity supply depends on transmission infrastructure operated by Tacoma Public Utilities.
Although Peninsula Light operates its own distribution system for customers in its service territory, it relies on Tacoma Power’s transmission lines to transport electricity into the area.
This connection helps explain why an issue at an important Tacoma substation can affect customers far beyond Tacoma itself.
When a significant problem disrupts the transmission connection, electricity may be interrupted across a large portion of Peninsula Light’s service area.
The October 16 incident demonstrated how a problem affecting one part of the regional electricity network can have consequences for thousands of customers served by more than one utility.
The scale of the disruption also highlights the importance of coordination between electricity providers during investigations and restoration work.
How to Check the Peninsula Light Outage Map
Customers who want to determine whether their address is affected can consult Peninsula Light Company’s official outage center.
The outage center provides access to outage information, reporting options, and updates from the utility.
Customers should check the official information rather than relying only on social media posts or older reports, especially when an outage is developing or restoration work is underway.
If electricity remains unavailable after neighboring properties have regained power, residents should report the problem directly to Peninsula Light.
Customers should also stay away from fallen power lines and damaged utility equipment. Downed lines should always be treated as energized, even when they appear inactive.
Anyone who encounters a dangerous electrical situation should keep a safe distance and contact the appropriate emergency or utility service.
