Types of Improvements

Electric Distribution System

Power lines typically located on wood poles next to the street or in your backyard that provide electric service to your house.

Installing smart devices

Without automated line devices, a problem on the line can cause all customers served by the line to lose power.

By adding automated line devices, outages are automatically isolated to smaller portions of the line so that fewer customers lose power when there’s an issue.

Adding connections

Without a connection to a nearby line, customers may not have an alternate source of power in the event of an outage.

By adding a connection to a nearby line, power may be rerouted to customers.

Relocating lines

Some lines are located in areas that are hard to access. In the event of an outage, this can increase the time it takes for a repair crew to get to the line and restore power.

Moving the line closer to the road makes it easier for a repair crew to access the line in the event of an outage and restore power more quickly.

Strengthening lines

Certain lines may benefit from targeted facility, material, and upgrades to improve power reliability.

Undergrounding lines

Overhead lines in certain areas may be more prone to outages caused by trees contacting lines or vehicular collisions.

Placing targeted portions of overhead lines underground makes lines less prone to outages.


Electric Transmission System

Large electric lines that carry bulk electricity over long distances from one area to another.

Replacing lines

Certain transmission lines may benefit from replacing the conductor on the transmission line while generally leaving the existing structures in place.

Replacing structures

Certain transmission lines may benefit from partial or full rebuild. A rebuild would typically include the replacement of all structures and wires.

Improving substations

Certain substations may benefit from replacing aging equipment. Substation improvements could include rebuilding the substation.
