Steel poles erected for power line

From Local Sources

DUFF — Steel sets of poles and H-frame structures being erected in parts of Dubois and Spencer counties are pieces of a new high-voltage transmission line that will run from a Duff substation to the Coleman Extra High Voltage substation in Hancock County, Kentucky.

The Duff-to-Coleman, 345kV (345,000-volt) electric transmission line will stretch more than 30 miles as it heads south from Duff, goes east of Holland, crosses I-64 northeast of Dale and snakes east of Santa Claus on its way to Hancock County, Kentucky.

Republic Transmission is collaborating with LS Power, Hoosier Energy and Big Rivers Electric Corp. to install the line needed to strengthen the region’s transmission grid.

Republic Transmission, which will own and operate it, says the project will allow lower cost generation to serve congested, large industrial loads and will increase system reliability by expanding the area’s 345kV backbone and completing a high voltage loop started years ago.

Vectren Corporation owns the Duff substation and Big Rivers Electric Corp. owns the Coleman EHV substation. Both utilities are expanding those substations to accommodate the transmission line project.

Planning and meetings for the project began in 2017 and it is expected to go into service in 2020.
