Our teams are working harder than ever to make our electric system smarter and more resilient with fewer outages—all while allowing seamless connection to clean energy sources.
Key Electric System Reliability Efforts
Smart Switches Fuses and Switches
Building a self-healing electric system
A smarter electric system means fewer and shorter outages. Over the past decade, we've installed thousands of smart devices on our electric system that can:
- Isolate power outages and restore thousands from a backup source in fewer than five minutes
- Automatically restore power when a fuse opens, like when a tree limb temporarily contacts a wire
- Protect the electric system when a problem is detected, such as a current surge or overload
Using stronger materials that can withstand forces of nature
To help withstand stronger storms, we're upgrading our infrastructure using more durable materials. Upgrades include:
- Replacing utility poles with more durable structures
- Replacing standard electric wire with sturdier, covered wire
- Replacing wooden high-voltage transmission structures with stronger steel structures
