我们非常认真地对待我们运营电网的责任. 如果情况威胁到我们安全运行系统的能力, 我们将关闭电源，保护公共安全. 在决定切断电源之前，我们考虑了很多因素. 这些因素包括, 但不限于:紧急情况下, 风速测量, 植被水分, temperature, humidity, 可持续发展目标的实地观测&来自消防部门的人员和信息.

We've developed a way to reduce the number of customers impacted when conditions may lead to a power shutoff in high-fire threat areas. Additional weather stations and electrical devices improve our ability to divide an electric circuit into smaller sections. We can be more precise when shutting off power so the number of customers impacted by a power shutoff is smaller.

Power will remain shut off as long as the threat to our system and public safety continues —that is, as long as winds are creating a safety issue near and around our electric infrastructure. 当风减弱一段时间后, our crews will then patrol the lines to check for system damage from wind-blown debris or any other problems before the power is turned on. 很难预测一次巡逻要花多长时间, 因为它取决于每根电源线的长度, 地形和是否需要空中巡逻. 有些线路位于农村山区，需要直升机巡逻. In those cases, wind speeds need to be below 35 mph for the helicopter to fly safely. 此外，出于安全考虑，我们的工作人员不能在夜间巡逻.

It’s important to remember that improved weather conditions are not the only factor that determines whether a line is safe to re-energize. 为客户恢复供电可能是一个漫长的过程. First, 我们需要在一段持续的时间内记录风速的下降, 然后为可持续发展目标留出4-8小时的日光&E外勤人员在线路上巡逻. 当巡逻, 工作人员正在寻找电线掉落等安全隐患, 被绳子缠住的碎片或树枝, 硬件损坏或通信线路相关问题. 电源线或电线杆是否有损坏, 在恢复供电之前，必须先进行维修.

In the case of fire or other adverse weather conditions, this process can take days. You may see our trucks in your neighborhood as you continue to experience an outage. 他们收集的信息有助于我们计划工作.

During a power shutoff, addressing hazardous situations like downed lines is a priority. 然后，我们会尽快恢复尽可能多的客户. We also prioritize repairs to restore service for critical needs 比如医院, 抽水站、警察和消防部门.

我们正在努力为所有人恢复供电, 你可能会看到附近的灯还亮着, 你的位置还不知道. 一个社区的不同部分可能在不同的电路上, 并不是所有的电路都在同一时间恢复.

SDG&E recommends investing in a landline to ensure a stable communication channel, as well as for SDG&E和急救人员在紧急情况下联系你. Additional solutions include purchasing a small radio with a crank or solar power to stay informed with the latest news. Many retail outlets offer low cost battery supply packs that should be kept charged and can provide backup charging power to your cell phone and other small electronics. 移动设备也可以在车内用低成本的适配器充电. It is always advised to know where your local law enforcement and fire stations are located; they should have the latest information.

如果你在高火力威胁区域, 可能有社区资源中心可以为小型设备充电, 或者你可以考虑在家里准备一台发电机.

Yes. SDG&E has the authority to turn off the power in emergency situations when necessary to protect public safety.

It’s important to remember that power lines from a well-maintained and well-designed power grid can still ignite a catastrophic wildfire. 在过去几年中，可持续发展目标&E has made major improvements to its electric grid when it comes to wildfire preparedness. But, 当存在危险的火灾条件时, it's  hard to prevent a tarp or a palm frond from whipping through 80 mph wind gusts directly into power lines, 点火. 这些都说明了可持续发展目标所需要的条件&我们必须计划和准备保护我们客户的安全. 在有风的情况下没有电力通过输电线, 一个点火源被移除, 保护我们的社区免受另一场灾难性野火的影响.
