High heat and California power grid strain

High temperatures are expected to continue this week in Northern California. The National Weather Service has an Extended Heat Warning in place for the Bay Area through at least Wednesday.

Stanford expects to have sufficient chilled water capacity for campus cooling needs during the coming week. No chilled water curtailment is expected at this time.

Over the weekend there have been rolling electricity blackouts during the evening in some areas of California, ordered by the California Independent System Operator (California ISO). While these blackouts did not affect Stanford, additional rolling blackouts in California are possible in the coming days, due to the strain placed on the power grid by the extreme heat in the Western U.S.

Please help conserve energy, especially during this period, and stay hydrated. Also take any precautions, including for research projects, in the event that a power outage occurs with little or no warning. PG&E is providing updates at https://pge.com and https://twitter.com/PGE4Me.

Community Alert

A Stanford AlertSU community alert has been posted at https://police.stanford.edu/alert

Chilled water curtailment ending

The current Stage 1 curtailment will end this morning, Monday, Sept. 2. Campus buildings will return to chilled water service by this afternoon. We expect this will be the final notification for this curtailment event.

Stage 1 Cooling Curtailment

Due to multiple warmer than normal nights with high humidity and forecast high temperatures, Stanford is implementing Stage 1 Chilled Water Curtailment starting immediately.

Under Stage 1, cooling is reduced in many offices and other parts of the campus not involved in medical, research, data processing and other facilities. Temperatures in occupied spaces are allowed to exceed campus guidelines. A complete description of the impact and a list of affected buildings can be found in Land, Buildings & Real Estate’s chilled water curtailment guide.

Works is progressing on the temporary cooling tower for the chilled water system that cools many buildings on the main Stanford campus and we expect to have it connected and operational on Monday. The new tower expands chilled water capacity on the campus by 35 percent.

Updates will be provided through the AlertSU system.

Chilled water curtailment ending

AlertSU: Chilled water curtailment on main Stanford campus ending Monday morning. Information at https://emergency.stanford.edu.

Cooling curtailment remains at Stages 1-2

Stage 1 and Stage 2 chilled water curtailment will continue on the main Stanford campus through the weekend.

We will continue to monitor campus loads and weather forecasts. This will be the final update until Monday unless circumstances change.

Please continue to consult the Chilled Water Curtailment Guide for additional information. Updates will be provided through the AlertSU system and at https://emergency.stanford.edu.

More Information on Chilled Water Curtailment

Stanford is continuing to implement Stage 1 through 4 Chilled Water Curtailment on the main Stanford campus this morning.

Here is more information about the situation:

CONDITIONS: Warm and very humid overnight conditions resulted in very large loads being pulled through the campus cooling system. The resulting reduction in our chilled water supply, combined with high forecast temperatures and humidity that will further tax the system today, led to the multi-stage curtailment that is now in effect. High humidity is a challenging part of this week’s conditions, as opposed to the high temperatures alone that were present last week.

ACTIONS YOU CAN TAKE: We are asking everyone on the main campus to help reduce the loads on the system. Turning off lights, closing blinds or covering windows exposed to direct sunlight, and turning off unnecessary equipment all help. See the curtailment guide for details, up to and including Stage 4 curtailment.

DURATION: The chilled water system is being continuously monitored, and updates are being provided to building managers every two hours. We do not have an expected duration for the curtailment. Forecasts for the next several days indicate an easing of overnight temperatures and humidity, but higher afternoon temperatures.

TEMPORARY TOWERS: After the cooling curtailment that occurred in June, new temporary cooling towers were ordered to increase the capacity of the chilled water system. These temporary towers have been scheduled to be in place by the end of August, but efforts are under way to accelerate their installation. In addition, longer-term plans are under way for increased chilled water capacity that will mitigate the need to curtail during extreme heat.

LAB SAFETY: Researchers should coordinate with building managers where needed regarding specific, localized mitigations to address impacts to research and equipment. As you do so, Environmental Health & Safety has the following reminders for those working in laboratories:

–      Wear proper PPE (personal protective equipment) and street clothes.

–      Avoid the use of fans in laboratories, as they may adversely affect exhaust ventilation.

–      PIs and supervisors must assess the conditions in their facilities to ensure safe and healthy working conditions. Check in with employees on their welfare and provide alternate work if conditions do not allow for safe lab work.

MANAGERS AND EMPLOYEES: During the cooling curtailment, managers should encourage precautionary measures and have discussions with employees about alternate work arrangements if needed due to the temperature in their location. If your manager is not available, please contact Human Resources for assistance.

Continued updates will be available through the AlertSU system and on emergency.stanford.edu.

Chilled Water Curtailment Stages 1-4 Today

Due to warm and very humid overnight conditions, forecast high temperatures and very high humidity today, and currently low chilled water thermal storage tank levels, Stanford needs to implement Stage 1 through 4 Chilled Water Curtailment starting immediately. Take immediate actions necessary to protect sensitive equipment.

Please reference the below Chilled Water Curtailment Guide for impacted buildings by stage and contact your building facilities representatives for additional support. All Stages 1 through 4 are included in this curtailment:

https://lbre.stanford.edu/sites/lbre-production/files/stanford_chilled_water_curtailment_guide_07-19-public_1.pdf

Building management in all buildings can help us to reduce chilled water load and prevent higher stages of curtailment by implementing the following measures:

  • Close window coverings on sunny exposures
  • Raise thermostat set points to 78F in office and common areas
  • Close laboratory fume hood sashes when not in use
  • Close operable windows in air conditioned buildings
  • Shut off unused office equipment
  • Turn off lights in unoccupied areas
  • Where possible, shut off lab equipment not currently being used

Updates will be sent when available and will be posted at http://emergency.stanford.edu.

Cooling curtailment ended on main campus

Cooling curtailment for all stages is now ended. Operations will return to normal over the next few hours.

Cooling curtailment easing on main campus

Cooling curtailment began easing on the main campus this morning, Friday, August 16, with cooling being restored incrementally in buildings covered under Stage 4 through 11 a.m. During that period conditions of the chilled water system will be monitored, as will actual versus predicted temperatures.

Stage 3 remains in place while cooling is restored in Stage 4 buildings. If all goes well with Stage 4 release, Stage 3 facilities will be evaluated.

Under Stage 3, temperatures in sensitive-conditioned teaching, research, or commercial operations spaces are allowed to exceed campus guidelines. A complete description of the impact and a list of affected buildings can be found in Land, Buildings & Real Estate’s chilled water curtailment guide: https://lbre.stanford.edu/sites/lbre-production/files/stanford_chilled_water_curtailment_guide_07-19-public_1.pdf

Additional capacity for the chilled water system that cools the campus is being planned in both the short and longer terms. To aid with short-term mitigation, temporary cooling towers are now being added to provide supplemental capacity. These temporary towers are expected to be in place by the end of the month. Even with these enhancements, the capacity of the system will be challenged by weather events that include temperatures in the upper 90s/100s over multiple days.

The university will be examining further ways of decreasing the load on the system in the earlier stages of a heat wave to prevent research disruption. Land, Buildings & Real Estate is forming an advisory committee of faculty members and facilities directors to assist with this effort.

Updates will be posted to emergency.stanford.edu after 11 a.m. and whenever there is further information.

Extreme heat: Curtailment update

A Stage 4 Chilled Water Curtailment is being maintained on the main campus through at least tomorrow, Friday, morning.

At Stage 4 curtailment, in addition to previous impacts already noted, temperatures in the research, data processing or communications spaces are allowed to exceed specifications and the water used to cool equipment in those spaces will be affected. The university is asking for your help in this curtailment. Please shut off all non-essential equipment to reduce load and preserve chilled water for essential needs. Researchers should coordinate with building managers if there are specific, localized mitigations they can undertake while the curtailment is in effect.

For further instructions, please see Land, Building & Real Estate’s chilled water curtailment guide: https://lbre.stanford.edu/sites/lbre-production/files/stanford_chilled_water_curtailment_guide_07-19-public_1.pdf

Extreme Heat: Continued curtailment

A Stage 4 Chilled Water Curtailment has been implemented on the main campus this afternoon.

Current temperatures are 4 degrees higher than yesterday’s record temps and about 8 degrees hotter than this morning’s forecast. We expect that temperatures will increase over the next few hours.

At Stage 4 curtailment, in addition to previous impacts already noted, temperatures in the research, data processing or communications spaces are allowed to exceed specifications and the water used to cool equipment in those spaces will be affected.

The university is asking for your help in this curtailment. Please shut off all non-essential equipment to reduce load and preserve chilled water for essential needs. Researchers should coordinate with building managers if there are specific, localized mitigations they can undertake while the curtailment is in effect.

Please see Land, Building & Real Estate’s chilled water curtailment guide for further instructions: https://lbre.stanford.edu/sites/lbre-production/files/stanford_chilled_water_curtailment_guide_07-19-public_1.pdf

The duration of the curtailment is unclear at this time. Updates will be posted to emergency.stanford.edu this evening and whenever there is further information.

During this cooling curtailment, managers should encourage precautionary measures and have discussions with employees about alternate work arrangements if needed due to the temperature in their location. If your manager is not available, please contact Human Resources for assistance.

Extreme Heat

ALERTSU: A Stage 3 Chilled Water Curtailment, affecting building cooling in more campus academic buildings and offices, is being implemented on the main Stanford campus this morning, Thursday, Aug. 15, and is expected to be in place at least through Friday morning.

Campus buildings are cooled by a chilled water system. Due to the unusually high current temperatures, along with expected high overnight temperatures, the Central Energy Facility (CEF) chilled water must be curtailed. A chilled water curtailment is required to reduce load and restore chilled water storage to normal levels.

Under Stage 3, temperatures in sensitive-conditioned teaching, research or commercial operations spaces are allowed to exceed campus guidelines. A complete description of the impact and a list of affected buildings can be found in Land, Buildings & Real Estate’s chilled water curtailment guide.

Note that the stages for curtailment are cumulative, so the buildings affected under Stage 1 and 2, which were implemented on Wednesday, remain in place. See the chilled water curtailment guide for details: https://lbre.stanford.edu/sites/lbre-production/files/stanford_chilled_water_curtailment_guide_07-19-public_1.pdf

The reduced load will help us make it through this heat wave. The duration of the curtailment is unclear at this time. Updates will be posted whenever there is further information.

During this cooling curtailment, managers should encourage precautionary measures and have discussions with employees about alternate work arrangements if needed due to the temperature in their location. If your manager is not available, please contact Human Resources for assistance.
