Due to the increased intensity and frequency of wildfires in Northern California, the California Public Utilities Commission has required that the electrical grid be powered down in areas prone to fires in times of elevated risk. In response, PG&E may, at times, implement an expanded PSPS that may impact Tuolumne County. PG&E has indicated it will provide notice 48 hours in advance of a planned power shutoff, when possible. Such notice will trigger the activation of the TCSOS’s three-phased response plan. During this response, you can expect email, voice message, and/or text message communications through our TCSOS emergency contact system.

  • PHASE 1: 48 HOURS PRIOR TO PLANNED POWER SHUTOFF: Early warning that PG&E has given 48-hour notification of a possible power shutoff and that the TCSOS is monitoring the situation. Under most circumstances, TCSOS will not initiate closures of schools or offices based upon this 48-hour notification. At this point, please plan to report to work until you receive further notice.
  • PHASE 2: 24 HOURS PRIOR TO PLANNED POWER SHUTOFF: You will receive an update informing you if the power shutoff has been cancelled/postponed or if it is still scheduled. If the power shutoff is still scheduled, you will be informed no later than 5 p.m. which schools and offices will be closed the following day. If your worksite will be affected, we will require that all computers, printers, copiers, and fax machines are unplugged prior to the outage. PLEASE NOTE: Even during an extended power outage, some functions of the TCSOS will continue and you may be expected to report to work. Your supervisor will communicate what is expected. At this point, please plan to report to work unless directed not to.
  • PHASE 3: DURING PLANNED POWER SHUTOFF: You will receive daily updates until the power is switched back on and schools and offices are back to business-as-usual. You will also be able to find updates at


Since notifications will be delivered through the emergency notification system, it is important your contact information is accurate. To ensure your information is up-to-date, please contact Troy Ashton at or speak with your supervisor.


At TCSOS, we believe that planning ahead is the best safeguard. With this in mind, we have provided more information and resources below to help you and your family prepare for an extended power outage. Please keep in mind that TCSOS employees affected by an extended power outage at home are expected to be prepared to attend work as regularly scheduled unless otherwise directed. All absences must be approved by a direct supervisor and reported either in Aesop or to your supervisor.

  • Make sure you can receive updated information from PG&E by updating your contact information at
  • Talk to your medical provider about a power outage plan for medical devices powered by electricity and refrigerated medicines. Plan for batteries and other alternatives to meet your family’s medical needs when the power goes out.
  • Review the supplies that are available in your household in case of a power outage. Have flashlights with extra batteries for every household member. Have enough nonperishable food and water stored to meet your family’s basic needs for at least a few days.
  • Use a thermometer in the refrigerator and freezer so that you can know the temperature when the power is restored. Throw out food if the temperature is 40 degrees or higher.
  • Keep mobile phones and other electric equipment charged and gas tanks full.
  • Know how to manually open electric garage doors and gates.

If you have questions regarding this communication, please speak with your supervisor. Together, we can work to ensure that employees, families, and students are informed, prepared, and safe during a power outage.
