Heat Wave Info

Older adults, children under four, people with existing medical conditions, and those without access to air conditioning are the most at risk of extreme heat issues and heat-related illnesses. To prepare for a heat wave, here is a list of trusted resources from the Director of the California Department of Aging to keep you and your loved ones safe, healthy, and cool during extreme heat. Help spread the word and share these resources with your family, friends, and communities.

Keep Cool in NEVADA County

Nevada County Cooling Centers

Nevada County’s Department of Social Services is activating Cooling Centers for residents due to extreme daytime temperatures and minimal overnight recovery. Residents can beat the heat in cool public places, like your local Nevada County Library branch, grocery stores, or movie theaters. 

Tue 9/6 through Fri 9/9

  • Cooling Centers will be open at Grass Valley and Penn Valley libraries from 10 am to 8 pm

Air-conditioned space and water will be available. Well-behaved pets on a leash are allowed, and both locations are ADA accessible. Library desk services will only be available during regular library hours, but residents can access the Wi-Fi and look at the materials while using the space.

The National Weather Service Sacramento has issued an Excessive Heat Warning for portions of Nevada County beginning Saturday morning 9/3/22 through Tuesday evening 9/6/22. Higher temperatures can be dangerous for all people, especially the very young, senior citizens, pregnant women, and those with chronic medical conditions. Nevada County’s Office of Emergency Services partners with Nevada County Public Health to plan for Excessive Heat Emergencies during high-heat events.

A Cooling Center is a temporary air-conditioned public space set up by local authorities to deal with the health effects of extreme heat over an extended period of time. Cooling Centers are meant to prevent hyperthermia, especially among the elderly without air conditioning at home.  Cooling Centers provide shade and water, along with referrals to social services. When there is the possibility of rotating power outages, charging stations may also be made available.

Weather Forecast

The National Weather Service Forecast Office in Sacramento has issued an Excessive Heat Warning that will be in effect from Saturday 9/3 at 11 am through Tuesday 9/6 until 8 pm. Forecast temperatures will reach 114 degrees in the valleys and 110 degrees in the foothills. Overnight lows are anticipated to be in the upper 80s in the foothills and upper 70s in the valleys. The NWS is also forecasting elevated fire conditions due to heat, dry fuels and very low humidity.

Reduce Energy Use/Flex Alerts

What is a Flex Alert?

Flex Alert is a call for consumers to voluntarily conserve electricity when there is an anticipated shortage of energy supply. When consumers reduce electricity use during a Flex Alert, it can prevent more dire emergency measures, including rotating power outages.

See Current Flex Alerts

See current Flex Alerts at www.flexalert.org. California ISO issues Flex Alerts to ask residents to voluntarily reduce their energy usage between the hours of 4 and 9 pm due to high temperatures pushing up energy demand and tightening available power supplies.

How to Reduce Energy Use

Conserve power (if health permits) by setting thermostats to 78 degrees or higher, avoid use of major appliances, turn off all unnecessary lights, and avoid charging electric vehicles.

PG&E urges customers to take immediate steps to voluntarily reduce their power usage and conserve energy by doing the following:

  • Raise the thermostat: Set the thermostat to 78 degrees when at home, health permitting. Turn it up to 85 degrees or turn it off when not at home.
  • Use a ceiling fan: Turn on a ceiling fan when using the air conditioner, which will allow the thermostat to be raised about 4 degrees to save on cooling costs with no reduction in comfort. Turn off fans and lights when you leave a room.
  • Cover windows: Use shade coverings and awnings so the air conditioner won’t have to work as hard to cool the home.
  • Avoid using the oven: Instead, cook on the stove, use a microwave, or grill outside.
  • Limit opening refrigerators, which are major users of electricity in most homes.
  • Clean clothes and dishes early: Use large energy-consuming appliances like washing machines and dishwashers earlier in the day or late at night after 10:00 pm.
  • Set your pool pump to run overnight instead of during the day.

Rotating Power Outages/Rolling Blackouts

When there is a high demand on California’s electric grid, PG&E may be ordered to do Rotating Power Outages through different PG&E service areas (by block number). Estimated restoration times are 2-3 hours after the outage actually starts. The situation remains dynamic and shutoff and restoration times may change.

If there is enough advance notice, you can learn if you will be affected by a Rotating Power Outage by finding your block number at https://www.arcgis.com/apps/instant/lookup/index.html?appid=04b7c901f2ff468daed74df54396d75e or on your PG&E bill in the section that says “Service Information.”

What causes Rotating Power Outages?

The need for outages is determined by the statewide grid operator, California Independent System Operator (CAISO), not PG&E. CAISO oversees the larger power grid and balances energy demand with supply. Rotating outages become necessary when CAISO is unable to meet minimum reserve requirements after demand reduction through Flex Alerts. Rotating outages are not related to any issues with PG&E’s equipment or its ability to deliver energy locally. Rotating Power Outages are due to strain on California’s grid and are different from Public Safety Power Shutoff (PSPS) events, which are initiated during specific high fire-threat conditions. (No PSPS events are anticipated by PG&E over the next seven days as of Friday, 9/2.)

Potential Announcements

Due to the nature of this type of emergency, if CAISO requires rotating outages, it is not always possible to notify customers in advance. However, these immediate actions are required to protect and minimize broader impacts on customers. PG&E will notify customers to the best of their ability via the web, media, and social network channels when CAISO grid strains are anticipated.

Monitor PG&E:

Unplanned Outages

Separate from rotating outages, some customers may experience unrelated power outages due to separate heat-related issues. PG&E restoration and repair crews are prepared to immediately respond to potential outages.

PG&E Advisory

As California experiences an extreme and extended heat wave, it is important to prepare for the potential of Flex Alerts, rotating outages, and unplanned outages.

Safety Tips

  • Keep devices and backup batteries charged and readily available
  • Have a backup plan to maintain any life-support equipment 
  • Keep important phone numbers, such as numbers for hospitals, fire departments, police, friends, and relatives in a convenient location in case you need emergency help or other assistance. 
  • Keep a charged cellphone or hardwired, single-line telephone on hand. Cordless phones don’t work without electricity. 
  • Keep a flashlight with extra, fresh batteries in a convenient place. Avoid using candles because of the fire risk. If you must light candles, use extreme caution. 
  • Turn off heat-producing appliances such as ovens, stovetops, and irons during an outage. This practice helps eliminate fire hazards that can occur when power is restored. 
  • Protect sensitive electronic equipment such as televisions and computers with surge suppressors. Unplug any such equipment that is in use when the power goes out.
  • Ensure that food stays cold by keeping your refrigerator and freezer doors closed.
  • Freeze water-filled plastic jugs to make blocks of ice. Place them in the fridge and freezer to help prevent food from spoiling.
  • Keep nonperishable food available that doesn’t require cooking. Ensure that you have a manual can opener.
  • Inform PG&E if you have a generator. Avoid using it unless you’re sure that it was installed safely and correctly. An incorrectly installed generator can damage your property. It can endanger you, and potentially harm PG&E’s line workers who may be working on nearby power lines. Read about the safe installation of generators: Visit Electric Generator Safety

Cooling Centers

PG&E also urges customers to stay safe during this heat wave. The company funds cooling centers throughout its service area to help customers escape the heat and cool off. If PG&E opens cooling centers near you, you can find them here: https://www.pge.com/en_US/residential/save-energy-money/savings-programs/cooler-locator/cooling-center-locations.page or call 1-877-474-3266.
