Recent Outage Recaps

March 11, 2025—At about 9am, approximately 700 customers in Sierra Meadows experienced a power outage. Power was restored to all customers by 11:15am.

Feb. 14, 2025—At about 8:10pm, about 2,700 customers experienced a short, two-minute outage, due to NV Energy needing to briefly cut power to one of our substations to complete transmission work.

Feb 13-14, 2025—Due to a severe winter storm, TDPUD experienced multiple localized outages across its system beginning the evening of Feb. 13. At about midnight, a transmission outage to one of our substations caused an outage for about 2,700 customers in the Sierra Meadows, Brockway, Airport, Deerfield, Cold Stream areas and parts of Downtown Truckee. NV Energy fixed the transmission issue at about 6:30am, and power was restored to all customers by 6:50am.

Additionally, at about 1:30am, two separate outages occurred. Once outage affected about 900 customers in Donner Lake, and smaller outage in Tahoe Donner. Power was restored to those customers by about 2:45am.

Feb. 7, 2025—At about 1:30am, we experienced an outage affecting approximately 700 customers. The outage was caused by a falling tree that grazed a power line. Power was restored to those customers at about 2:10am, but crews remained in the field to respond to other small outages due to the weather.

Jan. 7, 2024— At about 3:40pm, we experienced an outage affecting customers in Donner Lake. The outage was caused by a tree falling and breaking a power pole on South Shore Drive. TDPUD crews started work on replacing the pole, but since this would take a few hours, we also worked on restoring power to as many customers as possible by isolating the section of line that needed to be de-energized during the work. We first were able to restore power to customers on the west shore of Donner Lake, and by 6:30pm customers on the South Shore were restored as well. A handful of customers remained without power while the pole replacement was done.

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.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
