中断事件的开始

Regional storm bases and our Emergency Coordination Center open to support crew and resource coordination, response strategy and internal and external communication.

评估损失

As soon as conditions allow and it’s safe to begin field activities, our damage assessors drive to reported outage locations across our service area to:

• 识别潜在的安全隐患(例如.g.(电线倒下)
• Gain visibility of the damage and assess severity
• Report back to the regional storm base with details on the types of crew and equipment needed to restore power

Damage assessment is also a critical step to help us develop estimated restoration times for customers. In a region-wide outage event, damage assessment can take multiple days to fully complete.

建立风暴应变计划

Information from the damage assessors is used by the storm bases and Emergency Coordination Center to determine 资源 needed, outage restoration prioritization and other response strategies.

中断恢复优先级

• 第一个, repair crews focus on restoring power to essential services such as hospitals, 水/废水系统, 和运输. Priority power restoration also goes to high-voltage transmission lines that provide power to substations serving large numbers of customers in a broad geographic area.
• 下一个, crews focus on repairing damage to distribution and service lines – the lines that directly serve homes and businesses.
• 中断恢复优先级 is constantly evolving as we continue to gain knowledge of the situation and respond to emerging issues.

恢复工作继续进行

Our crews and outage response personnel work around the clock until all customers have their power restored.

初始ETR设置

在客户报告中断后, PSE’s System Operations team provides an initial estimated time of restoration (ETR), 对电力恢复时间的估计, 基于历史停机数据.

Restoration through 配电自动化

In many locations across PSE’s service area, power can be restored through 配电自动化 (DA) – often referred to as a “self-healing grid.” If an outage occurs on a DA-enabled distribution line, we can automatically isolate the source of the outage and quickly restore power to all customers who aren’t directly served by the damaged section of power line. This means we can reduce the number of customers affected by an outage and restore power more quickly.

评估损失

PSE’s Electric 第一个 Response team arrives at the outage location to assess field conditions and make the scene electrically safe. 第一个 responders may restore power to some or all remaining customers, depending on the location and severity of the damage.

人员分配

If our first responders identify the need for additional repairs, an electric crew from our service partner Potelco, 公司. 谁被派去修理. They will replace a pole, re-string electrical wire, or replace damaged transformers.

ETR更新

Estimated time of restoration (ETR) information is updated as more information becomes available, based on field conditions and 损伤严重程度.

检查

Once the high-risk weather conditions have subsided, crews will visually inspect the power lines to check for any damage or safety concerns before restoring power. PSE will work to safely restore power as quickly as possible, but there can be challenges if there is limited access or visibility, 或者附近的活火.

恢复阶段

天气“晴朗”: After the weather has passed and it is safe to do so, crews begin line patrols and inspections.
巡视和检查: Crews visually inspect for potential weather-related damage to lines, poles and other equipment.
隔离和修复损坏: 在哪里发现设备损坏, crews work to isolate the damaged areas from the rest of the system and restore any customers not served by the damaged equipment. 然后工作人员将进行必要的维修.
恢复供电: Once repairs have been made and it is safe to do so, PSE will restore power to customers.

估计恢复时间(ETRs)

As our field teams gain boots-on-the-ground visibility, we will add and update ETRs on the outage map.

• 区域ETR: The date/time we expect most customers in a larger region to have their power restored. Some customers will be restored sooner than the regional ETR, while other customers may have their power restored after.
• 字段ETR: Provided by our field personnel once line patrols are complete and updated as crews make any needed repairs.
