Testing the limits [electricity storage technologies]

In order to meet the energy demands of its customers effectively and efficiently, American Electric Power (AEP) has always tried to remain abreast of new, emerging technologies and has developed many technologies in its own laboratories. AEP began an in-depth study and comparison of different storage technologies in the late 1990s and started to fund the development, testing and application of several electricity storage technologies. This paper provides brief descriptions and background information on some of the more recent electricity storage technologies, either in use today or undergoing laboratory tests before their installation in AEP.
