Over the past couple of years, we have completed a few projects to harden our system to be more resilient to harsh weather. Notable projects include:

• Rebuilt five miles of three phase line northeast of Sidney going from our Colton substation back to the west.
• Reconductored (changed out wire) seven miles of three phase line south of Dalton going east from our Dalton Rural substation.
• Reconductored one mile of three phase sub transmission line going north from the Chappell substation.

These projects consisted of changing to T-2 conductor, also known as twisted pair. The design of this wire helps to shed ice during freezing fog and other winter storm conditions to reduce or prevent swaying or galloping lines. Galloping lines are very dangerous as they can collide with other lines causing outages, line equipment damage and in some cases damage to customer equipment. Additionally, when outages occur during these types of weather events it poses additional risk and hazards during restoration efforts.

We have other upcoming projects to increase the resilience of the electric system. More to come on that next month.
