Hawk Fire Power Outages – Customer Updates
8/23, 6:30pm —The switching work done today by TDPUD, Liberty Utilities, NV Energy and PG&E was successful, so we don't anticipate a wildfire-related power outage in Truckee this evening.
While there are no plans for a power outage tonight, it is still a good idea to always be prepared for wildfire-related outages at this time of year. Aside from the impacts of the Hawk Fire, we are in the heart of wildfire season, and wildfire-related power outages are often a possibility, whether it be preemptive power shutoffs when wildfire danger is high, or emergency de-energization when an active wildfire is near power infrastructure. To learn more about wildfire safety power outages, visit tdpud.org/wildfire.
8/23, 3:45pm —Thank you to our Truckee community for being cooperative and understanding regarding last night’s wildfire-related emergency de-energization power outage. Local utilities are still determining whether a similar outage will be needed this evening to support public safety, but in the meantime, TDPUD customers should prepare for the possibility of being without power for a few hours this evening.
Our region’s power providers — Truckee Donner PUD, Liberty Utilities, NV Energy and PG&E — are all working together on alternative solutions to avoid the need for a power outage this evening. This is the reason for the brief power outage at 3:30pm today. If these solutions succeed, we should be able to avoid de-energization in Truckee this evening.
Should we need to de-energize tonight, it would not be a full transmission outage like last night where the whole region goes dark. TDPUD, Liberty Utilities and NV Energy would work together to shed load to alleviate the strain on the transmission system, which is due to outages and damage caused by the Hawk Fire. Each agency would decide locally which areas of the system would be de-energized.
For TDPUD, our priority would be keeping power on for our critical infrastructure and the downtown area. We would decide which areas of the system would make sense to de-energize given the target that we are asked to reach. This outage would likely last for a few hours; we expect we will be able to return power to customers before midnight.
We will follow up with more information once it becomes available to us, including whether or not an outage will occur, and which areas would be affected.
Apagones por el incendio ‘Hawk Fire’ – Actualizaciónes para los clientes de TDPUD
23/8, 6:30pm: Los trabajos de conmutación realizados hoy por TDPUD, Liberty Utilities, NV Energy y PG&E se llevaron a cabo con éxito, por lo que actualmente no es necesario realizar un corte de electricidad en Truckee esta noche.
Aunque no hay ningún apagón planeado para esta noche, sigue siendo una buena idea estar siempre preparados para apagones relacionados con incendios forestales en esta época del año. Además de los efectos del incendio ‘Hawk Fire’, nos encontramos en plena temporada de incendios forestales, y los cortes de electricidad relacionados suelen ser una posibilidad, ya sean cortes preventivos cuando el peligro de incendio es alto o desenergizaciones de emergencia cuando un incendio activo se acerca a la infraestructura eléctrica. Para obtener más información sobre los cortes de electricidad por seguridad ante incendios forestales, visiten tdpud.org/wildfire
23/8, 3:45pm—Agradecemos a nuestra comunidad de Truckee por su cooperación y comprensión respecto al apagón, o corte de electricidad, de emergencia de anoche, relacionado con el incendio forestal. Las agencias de servicios públicos locales aún están evaluando si será necesario un corte similar esta noche para garantizar la seguridad pública, pero mientras tanto, los clientes de TDPUD deben prepararse para la posibilidad de quedarse sin electricidad durante unas horas esta noche.
Las agencias de servicios de electricidad de nuestra región —Truckee Donner PUD, Liberty Utilities, NV Energy y PG&E— están trabajando juntas en soluciones alternativas para evitar que sea necesario un corte de luz esta noche. Esta es la razón del breve apagón ocurrido hoy a las 3:30 p. m. Si estas soluciones dan resultado, deberíamos poder evitar otro apagón en Truckee esta noche.
En caso de que fuéramos obligados a realizar un corte del servicio eléctrico esta noche, no se trataría de un corte total de la red de transmisión como el de anoche, en el que toda la región quedó a oscuras. TDPUD, Liberty Utilities y NV Energy trabajarían en conjunto para reducir la carga y aliviar la presión sobre el sistema de transmisión, la cual se debe a las interrupciones y los daños causados por el incendio ‘Hawk Fire’. Cada agencia decidiría a nivel local qué áreas del sistema quedarían sin electricidad.
Para TDPUD, nuestra prioridad sería mantener el servicio de electricidad en nuestra infraestructura crítica y el centro del pueblo. Decidiríamos en qué áreas del sistema sería conveniente cortar el servicio de electricidad, considerando el objetivo que se nos ha pedido alcanzar. Es probable que este apagón dure unas horas; esperamos poder restablecer el servicio a los clientes antes de la medianoche.
Les mantendremos informados con más detalles tan pronto como los tengamos disponibles, incluyendo si se producirá o no un apagón y qué áreas se verían afectadas. Sigan nuestros canales de redes sociales o visiten tdpud.org/outage para ver las actualizaciones.

Recent Outage Recaps
Aug 3, 2026 — At 9:30am, we experienced an outage that affected approx. 1,700 customers in the Tahoe Donner area. Crews responded and found damage to TDPUD equipment. They made repairs and power was restored to all customers by 10:45am.
July 25, 2026 — Around 7:45am, we experienced an outage that affected about 750 customers in the Tahoe Donner area. Power was restored around 10:00am and the cause of outage was animal contact with our electric equipment and wildfire safety settings on our protective devices. Thank you for your patience.
July 13, 2026 — Around 4:45pm, we experienced an outage that affected about 1,700 customers in the Prosser/Alder Hill/Gray’s Crossing area. In the summer, our system is placed into wildfire safety settings, which require crews to visually inspect the line before we can restore power. This can take a few hours, which is why our summertime outages are usually lengthier. At first, we anticipated that—due to this inspection procedure—power would not be restored until 9pm. However, the outage occurred in an area of our system where we are currently running a pilot program to test out automated line sensor technology. Crews were alerted to the exact location of the fault, removing the need for the visual inspection. The cause of the outage was squirrel interference. Power was restored to all customers by 5:50pm.
Outage recaps will remain on the website for at least one week following widespread or extended outages.

What are the causes of power outages?
Electric power outages in Truckee's mountainous environment are primarily caused by severe winter storms (wind, snow, and ice) creating faults or damaging equipment. They are occasionally caused by equipment failures in TDPUD's electric distribution system, routine maintenance, or NV Energy transmission outages. Summer outages are typically caused by thunder storms, animals, transmission, and necessary wildfire mitigation safety practices.
TDPUD is a transmission dependent utility of NV Energy. This means that power is not generated locally and TDPUD relies on NV Energy's transmission system for our electrical supply. While NV Energy's reliability is generally good, transmission outages do occur and are beyond TDPUD's control.
During winter storms, the primary causes of outages are from snow or ice shedding from trees and power lines or trees and limbs falling and making contact with electric distribution equipment. Short duration interruptions - a few seconds - are the result of TDPUD's protection equipment which can distinguish between a temporary fault (snow shedding from on onto power lines creating a temporary fault, for example) and an outage requiring field repair. In the temporary fault situation, the protection equipment automatically re-energizes the line preventing a much longer outage.
During the summer and fall months, outages are caused primarily by thunder storms, animals getting into TDPUD's electrical equipment, transmission, and changes in operations for wildfire mitigation. TDPUD wildfire mitigation safety practices increase the duration of power outages during wildfire season which extends into the summer and fall months. New California laws and regulations require that TDPUD modify operations to minimize the chance of ignition. In many cases, TDPUD is required to visually patrol all circuits in an outage to ensure that restoring power does not cause a fire. The end result is longer outages during wildfire season. See TDPUD's wildfire page for more information..
TDPUD's dedicated staff takes reliability very seriously, work hard to prevent power outages, and respond quickly when they do occur.
How do I report a power outage?
If your home or business loses power, before you report a power outage to the TDPUD you should check to ensure that TDPUD is the cause of the power outage. If you are at home, first check your circuit breakers and look outside to see if there is any damage on your property. Also check to see if your neighbors power is out or not.
If you are experiencing an electric outage, to report the outage call TDPUD at 530-587-3896.
TDPUD takes reliability and safety very seriously. We work hard to maintain our electric system and respond quickly to outages.
Outage Management System FAQ
What is OMS?
OMS stands for Outage Management System, and it is the new notification system that the TDPUD will be using to communicate with customers during a power outage.
How do I sign up for OMS?
Customers should log on to their TDPUD SmartHub Account and verify their contact information in order to receive OMS text alerts. Once in SmartHub, customers must go to “manage contacts” under the notifications tab, confirm their mobile number, click the box to receive text messages and follow the instructions to receive a 6-digit code and complete the verification. Check out the OMS text verification tutorial for step-by-step instructions with pictures.
How is OMS different than previous TDPUD outage communications?
- OMS is able to send automatic notifications when an outage is predicted, so you’ll know in almost real-time when you’re experiencing an outage.
- OMS can identify exactly which homes and businesses are being affected, which is how it only sends notifications to the customers who are experiencing the outage.
- OMS gathers information from a number of sources, and for the first time integrates all of this analysis in order to predict outages and their impacts, as well as communicate them to customers.
- At the individual account level, it gathers real-time information from the “smart meter” system we utilize to collect power information and detect interruption at each meter.
- At the infrastructure level, it gathers real-time information from the data monitoring and control system at the substations and electric feeders. This is the equipment that facilitates the delivery of power from transmission lines to local distribution lines.
- It uses our improved mapping system to trace the impacts of an outage. It can detect where an outage will originate, and then follow the model to know which homes and businesses will be impacted.
- It uses our SmartHub customer service system to log information from customer calls to our call center. It also utilizes the customer profile information in SmartHub to communicate with affected customers.
- The way these systems work together for the first time is what sets OMS so far apart and ahead from the previous outage notification systems TDPUD has used.
How can I receive OMS alerts if I am not the account holder for my residence?
OMS alerts can only be sent to the contact information associated with the utility account. If you are a resident but are not on the TDPUD account, you can visit tdpud.org/outage to find information during a power outage. You should also sign up for TDPUD Nixle emergency alerts by texting TDPUD to 333111. Text and email alerts will still be send via Nixle during an outage if it impacts a significant amount of the community.
How do I get information on outages if I am visitor and renting a home for vacation?
Visitors can visit tdpud.org/outage to find information during a power outage. They can also sign up for TDPUD Nixle emergency alerts by texting TDPUD to 333111, but alerts will only be sent via Nixle for large-scale outages.
What kinds of alerts will OMS send me?
Customers can expect email and text alerts for when an outage occurs, when a restoration time is established if available and when power is restored.
Why did I get an OMS alert when my power isn’t out?
We are rolling out this new OMS in a “beta launch.” As a new system, we know that everything might not be functioning perfectly to start, but through real-world usage and customer feedback we plan to use the next few months to make the necessary changes to optimize the system.
If you receive an outage notification when you’re not experiencing an outage, or don’t receive one when you are, please share your feedback with us by emailing service@tdpud.org.
