Powering Off for Wildfire Safety
A Public Safety Power Shutoff (PSPS) is when an electric utility temporarily shuts off power to reduce the risk of a fire caused by utility equipment. Dangerous fire weather conditions — which include strong winds, dry vegetation and low humidity — drive PSPS events.
Losing power for any amount of time is a hardship; while it’s frustrating and inconvenient, safety must come first. Our mission is to keep the power on when it is safe to do so.

4-7 Days Ahead
When forecasts indicate extreme fire conditions, we begin predictive modeling to assess potential impact. Our weather awareness map shows counties of concern for PSPS up to seven days ahead.
4 Days Ahead
We continue to refine predictive models. Incident responders are placed on alert.
3 Days Ahead Notification
When extreme fire conditions are forecast, we coordinate with the emergency management community, first responders and local government.
We notify potentially affected customers and show affected areas on the Outage Map. PSPS areas are indicated with lines showing the potentially affected circuits. Not all PSPS events can be forecasted this far in advance.
2 Days Ahead Notification
As the forecast becomes more precise, we update the list of circuits that might be impacted. If weather conditions persist, impacted customers and public safety partners receive a notification confirming the PSPS event and timing.
1 Day Ahead Notification
When extreme fire conditions are imminent, we continue to coordinate with the emergency management community, first responders, local government and customers of possible PSPS.
1-4 Hours Before Shutoff Notification
If we estimate that power could be shut off within one to four hours, an expected shutoff notification will be sent to customers, when possible. Once customers receive this notification, power shutoffs could happen at any time until the end of the PSPS event.
Power Shutoff Notification
When wind speeds and fire conditions are about to reach or exceed predetermined thresholds, we notify the emergency management community, first responders, local government and customers when we shut off power.
Before Power Restoration Notification
When fire conditions subside and PSPS is no longer needed, field crews will check lines to make sure power can be safely restored. Customers are notified when line inspections begin. It typically takes up to eight hours for inspections to be completed for all deenergized lines or it might take more time if daylight is required by foot or helicopter patrols.
Restoration Notification
All customers notified about PSPS will receive a final notification when their power has been restored or when the event has ended.
Other notifications may occur as needed to keep customers informed.
Disclaimer: Our advance forecasts might not capture the real time onset of strong winds or other dangerous fire conditions. In these cases, there might be little to no notice before power is shut off for PSPS. After a shutoff, customers will be notified as soon as possible and can check the Outage Map to confirm it is due to PSPS.
在危險的火災天氣條件下,當預測強風、乾燥植被和濕度過低時,我們便會考慮公共安全斷電措施。在這些條件下,火勢可能會迅速蔓延,造成重大安全風險。PSPS 可降低強風導致樹枝或其他碎片殘骸接觸電力設備並引發火災的風險。
PSPS 的決策是基於 PSPS 電路上或架設於鄰近的電線桿頂部之小型氣象站的即時天氣報告。在切斷電路或電路段的電源時,我們主要會考量以下因素和條件:
- 強風
- 低濕度
- 可作為燃料的乾燥植被

Customers who live in high fire risk areas are more likely to experience PSPS. However, customers who live near high fire risk areas may also be affected because they are connected to power lines that run through or near high fire risk areas.
如欲查詢您是否位於高火災風險地區,請在我們的停電地圖上輸入您的地址,並選擇「高火災風險地區」篩選條件。
雖然有些客戶的住家或公司可能沒有遇到強風,但他們所使用的電路可能源自或經過一處風勢強勁的高火災風險區,然後才到達他們的地址。因此,某一區塊或社區可能仍有電力供應,而鄰近區域則沒有。我們會盡力透過暫時切換至鄰近電路,來降低停電影響,但這並非在所有情況下都可行此外,所有電路在恢復供電前,都必須由地面工作人員進行目視檢查,因此各電路的復電時間可能會有所不同。
Resources and Preparedness Frequently Asked Questions
Resources and Preparedness FAQ
有時 PSPS 可能會持續超過 24 小時。制定緊急應變計劃,以確保停電期間家人的安全。其中應包括緊急物資的位置清單,例如瓶裝水、電池式收音機、手電筒、急救箱、額外毛毯以及可用的電池。
- 延長停電的準備建議。
- 查找為有行動或功能需求的客戶提供的資源與支援,以及社區協助與緊急應變資訊。
- 註冊 PSPS 通知,可選擇英文或其他可供語言。
如果您或家中有人因健康因素需依賴電力,您可能符合資格申請我們的 Medical Baseline Allowance 計畫。
SCE 在 PSPS 及其他大型公共安全事件期間,透過社區資源中心 (Community Resource Centers) 與社區行動車 (Community Crew Vehicles) 為客戶提供協助。在 PSPS 期間,請造訪停電地圖 (Outage Map)查看相關地點資訊。地點通常會在公告的 PSPS 停電前最多提前一天公布。
服務包括資訊、輕食和應變工具包。客戶也可在現場為行動裝置與可攜式醫療設備充電。我們也提供多語言支援,並協助有身心障礙或其他行動與功能需求的客戶。
為了更好地為 PSPS 和其他緊急停電做好準備,我們通過自行發電獎勵計畫 (SGIP) 提供獎勵措施。當停電或 PSPS 發生時,這些系統可作為備用電池為您的家庭供電。
居住在高火災風險地區或其他符合條件的社區的客戶,可能符合申請 SGIP 韌性獎勵補助的資格。不住在高火災風險地區或其他符合條件的社區的客戶仍然可以申請 SGIP 的一般市場獎勵。
如需更多資訊,請參閱《SGIP 住宅用戶電池儲存資料表》。
造訪SCE Marketplace,選購可攜式電源站與發電機。可攜式電源站可為筆電、手機、平板與部分網路路由器等小型設備與家用電器提供備援電力。可攜式發電機則可供應冰箱、照明、水泵與車庫門等大型家用設備所需的備用電力。
