Oct. 9 (1:06pm): Message from COO Brian Sherin

The first phase of the Bay Area PG&E Public Safety Power Shutoff was initiated last night, with more than 500,000 customers affected in the North Bay. Phase two is scheduled to begin this afternoon, affecting a number of counties, including San Mateo, Santa Cruz, Santa Clara, and Alameda.

At this time, we are being informed by PG&E that they do not anticipate impact to SLAC or Stanford University’s power supply. Normal operations are continuing at the lab. If the situation changes, we will notify staff using the SLAC911 emergency alert system. 

I urge anyone who hasn’t added their cellphone number to their MyHR profile to do so as soon as possible. This will ensure you receive Emergency Alert notifications should email access be impacted.

We are monitoring the situation closely and are taking precautionary steps such as topping off fuel and bulk gas tanks and securing backup generators for critical systems. 

Even as the lab remains operational, keep in mind that this event is already affecting our people in many different ways. If you are personally affected by this event, work with your manager on alternative work arrangements. Please take care of yourselves and each other as we navigate this unprecedented situation.

Please continue to check this website for periodic updates and talk to your manager about any concerns.

Oct. 8 (6:45pm): There have been no further updates pertaining to SLAC this afternoon on the PG&E power shutoff situation in Northern California. SLAC will be open and operating on Wednesday, October 9. Please continue to refer to the links and resources below. For staff employees, if a PG&E power shutoff at your home or at your child’s school affects your ability to come to work, please contact your manager to discuss any arrangements that may be needed.

Oct. 8 (10:20am): As of this morning, the latest information we have from PG&E about a Bay Area Public Safety Power Shutoff (PSPS) is that SLAC and Stanford campus will not be affected. However, the situation is fluid and we will continue monitoring for changes.

The lab plans to continue operations as normal. Soft preparations are underway in case conditions change.

Staff can check for updates on the PG&E website to see if their homes will be affected. Any personal arrangements should be made in agreement with your supervisor. PG&E advises that affected areas should prepare for up to five days of no power.

Oct. 7 (5:10pm): As stated in the Stanford AlertSU email, PG&E is considering a Public Safety Power Shutoff (PSPS) on Wednesday and Thursday throughout much of the Bay Area.

Please keep in mind that Stanford and SLAC receive power through different lines, so impacts of a potential PSPS event may differ for each site.

We are monitoring the situation closely and will send SLAC-specific information as conditions change.

AlertSU email communication from Stanford University to all staff, 4:45pm Oct. 7:

PG&E announced today that it is considering Public Safety Power Shutoffs on Wednesday and Thursday in portions of many counties in Northern California and the Bay Area. These potential shutoffs are being considered due to expected high winds and elevated fire danger in the region on Wednesday and Thursday.
 
At this time, Stanford sites including the main Stanford campus, Stanford Redwood City and the SLAC National Accelerator Laboratory are NOT among the areas expected to be affected by these shutoffs. The Jasper Ridge Biological Preserve, in the foothills to the west of the main Stanford campus, could potentially be affected.
 
Stanford is monitoring the situation and will provide updates if the situation changes.
 
Because it is possible for the situation to change with little or no notice, we encourage those running research operations or other activities that could be damaged by an unexpected power outage to consider the option of postponing operations beyond this Wednesday and Thursday, where possible. While PG&E has said it will aim to provide at least 8 hours of notice in the event of an actual power shutoff, this notice is not guaranteed.
 
Environmental Health & Safety offers preparation guidance for researchers and those working in lab environments.
 
In addition, please be aware that even if Stanford is not affected by an outage, your home could be. Please consult the PG&E website for details and tips for anticipating a power outage.

Updates will be sent via the AlertSU system if the situation changes, and any new information also will be posted at 10 a.m. Tuesday at https://emergency.stanford.edu
