AES Ohio announces $175M transmission project in Fayette County

AES Ohio is building a new facility in Fayette County that is designed to improve the capacity and reliability of electric service in the AES Ohio transmission system.

This $175 million project located near the new L-H Battery Company is a joint venture between LG Energy Solutions and Honda. It represents the most significant construction project for AES Ohio in three decades.

The project includes the installation of 13.5 miles of new transmission lines and a new substation, critical for supporting the expansion in Fayette County and beyond.

“Our collaboration with the L-H Battery Company is not just about enhancing infrastructure—it’s about empowering communities, creating jobs and leading the charge toward a sustainable, electrified future. We are proud to be at the forefront of this transformative era for Ohio,” Tom Raga, president of AES Ohio, said.

The project has three phases aimed at improving the grid’s reliability and resilience. Phase 1 is nearing completion and is scheduled for the end of 2024. The Fayette substation has two 345 kV lines and uses two transformers to supply the L-H Battery Company.

Phase 2 involves the construction of a new Jeffersonville substation, replacing the existing substation. The completion date for Phase 2 is the end of 2026.

Phase 3 plans include building a new Octa substation and linking it with the Fayette and Jeffersonville substations. This phase is slated for completion in 2028.

AES Ohio provides service to more than 539,000 customers in West Central Ohio.
