Key Features

Republic Transmission Improving Reliability

Improving Reliability

MISO determined the Republic Transmission’s new extra-high voltage transmission line would increase reliability by strengthening the region’s transmission backbone.

Republic Transmission Reducing Costs

Reducing Costs

MISO estimates our transmission facilities will provide over $1 billion in consumer cost savings. Expanding the area’s 345 kV backbone transmission grid and completing an awaited high-voltage loop allows lower cost generation to reach large industrial loads, businesses, and consumers.

Republic Transmission Renewable Energy

Facilitating Renewable Energy

By expanding the 345 kV backbone, Republic Transmission’s facilities further enable the delivery of renewable energy across the MISO footprint. During periods of high renewable resource output, Republic Transmission’s facilities improve MISO’s ability to efficiently deliver excess, low-cost renewable energy to broader areas of the region.

Republic Transmission Competition

Competition is Our Difference

Competition for new transmission development brings significant value to electricity consumers and the regions in which they live. Our company was selected through a competitive bidding process pursuant to FERC Order No. 1000 to develop Republic’s transmission facilities. Because of this competitive process, MISO received a cost-effective, innovative solution that answered unique challenges — crossing the Ohio River with an overhead transmission line and related mitigation and clearing restrictions associated with threatened and endangered species — to its request for proposals.

How the MISO Electric Market Works
