An Appalachian Power Co. affiliate will file requests this year with regulators in West Virginia to make more than $337 million in upgrades in its power grid, the company announced Wednesday.

The upgrades made by AEP West Virginia Transmission Co. Inc. are meant to accommodate power plant retirements in the Kanawha and Ohio valleys that will change the way electric power flows on the transmission grid as well as address additional issues identified by an independent regional transmission operator. Most of the work on the grid is planned for Kanawha Valley.

The upgrades include rebuilding around 52 miles of existing transmission lines as well as making upgrades to substations. For the rebuild, the company will remove current transmission facilities and replace them with similar but sturdier facilities of the same voltage.
