PROJECT:
Duff to Coleman
Increasing electric transmission capacity while providing cost benefits
Based on the need identified by the Midcontinent Independent System Operator (MISO), Republic Transmission is installing a new high-voltage transmission line between the existing Duff substation in southern Indiana and the existing Coleman EHV substation in northern Kentucky. To execute the Duff to Coleman Project, Republic Transmission has collaborated with three experienced utility companies: LS Power, Hoosier Energy and Big Rivers Electric Corporation. The result will be safe and reliable delivery of power while lowering system costs for consumers across the entire MISO electric transmission grid.

How the Electric Market Works
GENERATION
Generation companies turn energy sources, including natural gas, coal, nuclear, solar and wind, into electricity. This energy is then sold on an open market to retail electric providers that, in turn, sell it to consumers and businesses.
TRANSMISSION
Electric transmission companies like Republic Transmission operate and maintain high-voltage transmission lines to deliver bulk power to retail electric providers.
DISTRIBUTION
After retail electric providers receive the bulk power, they use a lower voltage distribution system to distribute it to consumers and businesses.
