Biers Run Substation Project

The Ohio Power Siting Board has approved AEP Ohio Transmission Company (AEP Ohio Transco) application to construct the Biers Run Substation in Ross County.

The Biers Run Project is a major transmission reinforcement project to help AEP Ohio and AEP maintain an adequate level of transmission reliability in southern Ohio. The new Biers Run Substation will allow AEP to address reliability concerns about potential low voltages and thermal overloads under certain conditions. Without this substation, in a worst case scenario, uncontrolled widespread power outages affecting major portions of southern Ohio may materialize. AEP studies indicate that without this reinforcement plan, the performance of the company’s transmission system will be inadequate to provide the level of service that its customers expect.

Prior to filing an application with the power siting board, AEP Ohio held a public meeting for residents in the project area. The company included the information and comments gathered during this meeting in its application. More information about the Ohio Power Siting Board process and a copy of AEP’s certified application can be found at under case number 12-1361-EL-BSB.

Project Information:

Project Benefits

The proposed station will allow the company to address reliability concerns about potential low voltages during certain contingency conditions.

Purpose and Need

The project will resolve voltage concerns in this area by establishing a new 345/138/69-kV source in the southern Ohio area, reinforcing the existing system.

Economic Benefits

AEP’s overall investment in the Biers Run Project is estimated to be $97 million and includes improvements at several existing substations, transmission line upgrades and construction of Biers Run Substation.

The Biers Run Substation portion of the project is estimated to be $12 - $14 million. The 345-kV transmission line loop into the substation is projected to cost about $2 million.

The project will produce additional tax revenue for local schools and communities. AEP projects that the new substation will contribute between $550,000 to $650,000 in property taxes to Ross County, Union Township and the local community. During construction, the project will create approximately 50 temporary jobs within the community.

The new substation also will provide capacity for economic growth in the area.
