AEP Ohio and its partners are building a secure, interoperable, and integrated Smart Grid infrastructure in Ohio that demonstrates the ability to maximize distribution system efficiency and reliability, and consumer use of demand response programs to reduce energy consumption, peak demand costs, and fossil fuel emissions. The demonstration area includes 150 square miles including parts of Columbus, Bexley, Gahanna, New Albany, Whitehall, Reynoldsburg, Westerville, Blacklick, Johnstown, Alexandria, Minerva Park, and Pataskala. This area includes approximately 110,000 meters and 70 distribution circuits. AEP Ohio will implement Smart Grid technology over 58 13kV circuits from 10 distribution stations and 12 34.5kV circuits from six distribution stations. Included in this project is a redistribution management system, integrated volt-VAR control, distribution automation, advanced meter infrastructure, home area networks, community energy storage, sodium sulfur battery storage, and renewable generation sources. These technologies will be combined with two-way consumer communication and information sharing, demand response, dynamic pricing, and consumer products, such as plug-in hybrid vehicles.

The plan was to integrate 80 CES (25kW/25kWh) units of storage resources into the existing grid. After initial testing, AEP Ohio began field installations and commissioned 15 CES units into operations by December 31, 2011. Following this deployment, technical issues were discovered and the CES units were not performing to AEP Ohio’s stringent standards. The CES units were removed from the field and returned to S&C. This component of the project has been redefined to include a limited deployment of four CES units at an outdoor test environment on AEP Ohio property to continue extensive testing.
