Idaho Power rebuilding transmission lines

Crews from Idaho Power reconstructing more than 100 miles of high-voltage power lines in northern Idaho, the outgrowth of a high-tech maintenance project begun last year.

“We started a project where we’re surveying all of our transmission lines, 138-kV and above,” using light detection and ranging (LiDAR) measurements, an Idaho Power spokesperson told TransmissionHub on July 2.

“Next year, we’ll put all that data into a report but in the meantime, we’re getting some data back so we’re going ahead and making any repairs or maintenance upgrades that we need to do based on what we’re seeing out there right now,” the spokesperson said.

Repairs and maintenance were shown to be needed on the 70-mile, 230-KV line Ontario-La Grande line and the 60-mile, 138-kV Ontario-Baker line.

“We’re replacing some structures. In some places, full H-frame poles, some cross arm structures, any equipment that needs upgrading,” the spokesperson said.

The maintenance and reconstruction work is to ensure reliability throughout the company’s service area, and meets a new mandate from NERC, the spokesperson said.

Idaho Power is the chief operating subsidiary of holding company IDACORP, Inc. (NYSE: IDA).
