A widespread Tacoma Public Utilities (TPU) power outage left thousands of customers without electricity across Tacoma and surrounding communities in Pierce County, Washington, on Friday, October 16, 2026.
The interruption affected homes and businesses in Tacoma, University Place, Ruston, and other areas, while a separate but related disruption extended across Gig Harbor and the Key Peninsula.
At the height of the incident, approximately 25,000 Tacoma Public Utilities customers were reported to be without power. The outage also affected tens of thousands of customers served by Peninsula Light Company, bringing the combined reported impact across the region to nearly 50,000 customers.
Tacoma Public Utilities identified an issue involving its Pearl Street substation as crews worked to determine the problem and restore electricity. The substation issue also affected Peninsula Light Company because the utility receives power through Tacoma Power’s transmission lines.
By Friday afternoon, electricity had been restored in Tacoma and University Place, according to local news reports. However, an outage update published during the restoration effort indicated that some TPU customers remained without electricity.
The incident disrupted normal activities across several communities and prompted residents to seek information about the cause, affected areas, and restoration progress.
What Happened During the TPU Power Outage?
The widespread outage developed on Friday morning, October 16, with multiple areas experiencing interruptions within a relatively short period.
According to reporting by local media, Tacoma Public Utilities’ outage map initially showed approximately 25,000 customers without electricity across Tacoma and University Place.
Peninsula Light Company also reported widespread outages affecting its service territory, which includes Gig Harbor, the Key Peninsula, and nearby islands.
As the situation developed, TPU spokesperson Mike Halliday told The News Tribune that the utility was experiencing a problem at its Pearl Street substation. Crews were heading to the facility to investigate the issue and work toward restoring electricity.
The interruption affected more than one neighborhood, demonstrating the potential reach of a problem involving important electrical infrastructure.
Residents reported losing electricity at different times, while some said their service returned as crews worked through the restoration process.
The outage maps and customer estimates changed throughout the day as utilities assessed the situation and brought affected sections of the network back online.
Pearl Street Substation Problem Linked to the Disruption
Tacoma Public Utilities identified an issue at its Pearl Street substation as a major factor in the October 16 power disruption.
Substations are important components of an electricity distribution network. They help regulate voltage and direct electricity through the grid to homes, businesses, and other facilities.
A problem at a key substation can affect multiple circuits and interrupt service across a broad area, depending on the equipment involved and how the electrical network is configured.
The Pearl Street issue also affected Peninsula Light Company’s service territory. The company explained that it receives electricity through Tacoma Power’s transmission lines, meaning a disruption affecting those lines can have consequences for its customers.
At the time of the initial reports, utility crews were working to determine the precise problem and address it.
The available reporting did not establish the specific technical failure responsible for the incident. It would therefore be premature to attribute the outage to a particular equipment malfunction or other cause without further confirmation from the utility.
Nearly 50,000 Customers Reported Without Power
The October 16 outage affected a substantial number of customers across Pierce County.
Early reports indicated that approximately 25,000 Tacoma Public Utilities customers were without electricity. As restoration work progressed, the number shown on TPU’s outage map declined.
Peninsula Light Company separately reported that approximately 36,067 customers across Gig Harbor and the Key Peninsula were affected at one point during the incident.
Combined estimates from local reporting placed the number of affected customers across the two utility systems at nearly 50,000.
These figures reflect different reporting points during the incident and should not be treated as a final count of every customer who lost electricity.
The outage affected both residential and commercial areas. For households, the interruption meant losing access to lighting, appliances, internet equipment, and other electrically powered services. Businesses also faced the possibility of disrupted transactions, refrigeration, and daily operations.
The changing customer totals reflected the evolving nature of the outage as the utilities investigated the problem and restored service.
Which Areas Were Affected by the TPU Outage?
The outage affected multiple communities in the Tacoma area and across the wider Pierce County region.
Reported locations included:
- Tacoma: Thousands of Tacoma Public Utilities customers experienced electricity interruptions.
- University Place: The city was among the communities affected by the outage.
- Ruston: Outage reports identified interruptions affecting customers in the area.
- Gig Harbor: Peninsula Light Company reported widespread service disruptions.
- The Key Peninsula: Customers across the peninsula were affected by the related interruption.
- Fox Island and nearby islands: Community reports described outages extending into additional parts of the region served by Peninsula Light Company.
The precise number of affected customers varied by location and changed as restoration progressed.
Not every property in these communities necessarily lost power, and individual neighborhoods may have experienced different outage durations.
Residents who continue to experience an interruption should check their electricity provider’s current outage information rather than relying exclusively on broad regional updates.
Power Restoration Progress Across Tacoma and University Place
Tacoma Public Utilities and Peninsula Light Company worked to restore electricity after the substation problem was identified.
During the restoration process, TPU’s reported number of affected customers declined from approximately 25,000 to around 12,593, according to updates carried by local media.
A later update indicated that approximately 1,493 TPU customers remained without power in the utility’s service area.
Peninsula Light Company also reported progress. By early afternoon, the company announced that electricity had been restored to its customers.
By 3:29 p.m. Friday, local reporting said power had been restored to Tacoma and University Place.
These updates offered relief to residents and businesses that had spent part of the day without electricity.
However, restoration figures recorded at different times represent a developing situation. Customers who experienced a continuing or subsequent outage should verify their property’s status through the official outage map.
Latest reported status: Power was reported restored in Tacoma and University Place, and Peninsula Light Company announced restoration for its customers on Friday, October 16. The initial reports did not establish whether every individual service interruption across the wider region had been resolved.
How the Outage Affected Residents and Businesses
The loss of electricity across several communities created uncertainty for residents who depend on reliable power for everyday activities.
Households may experience difficulties with refrigeration, lighting, heating or cooling equipment, internet access, and electronic devices during an outage.
Businesses can face interruptions to payment systems, food storage, communications, and equipment required for normal operations.
The disruption also generated frustration among residents seeking updates. Some people reported difficulties accessing outage maps or reaching utility phone lines while the incident was developing.
Such challenges can occur during large-scale outages when many customers attempt to obtain information simultaneously.
Clear communication is particularly important during a widespread interruption because customers need to understand whether their address is affected, whether crews are working nearby, and whether an estimated restoration time is available.
For residents who depend on powered medical equipment, an outage can present more urgent concerns. Having a backup plan and knowing how to access assistance can be important when electricity is interrupted unexpectedly.
How to Check the TPU Power Outage Map
Customers served by Tacoma Public Utilities can use the utility’s official outage information page to track reported interruptions and report new outages.
The outage map can help residents determine whether their area is affected and review updates as information becomes available.
Customers should be aware that restoration estimates may change as crews assess damaged equipment and determine the repairs required.
Anyone who sees a downed power line should stay well away and report the hazard. Downed lines should always be treated as energized, even when the surrounding area appears to have no electricity.
Customers should avoid attempting to inspect or repair utility equipment themselves.
If power remains off after nearby homes have regained service, residents should report the problem directly to Tacoma Power or the electricity provider responsible for their address.
