dc.description.abstract | Most Army installations purchase electricity from local utilities and pay an additional charge for peak demand. If the peak demand can be reduced, installations can realize significant cost savings. This research investigated the technical and economic issues associated with constructing a small scale superconducting magnetic energy storage (SMES) system for reducing peak demand at Army installations. Analyses included magnetic design parameters, and costs of materials currently available and those being developed. Although advanced materials could reduce costs by as much as 45 percent, current SMES technology is still too costly for use at Army installations. Technological advances and future wide-spread use of SMES systems may reduce costs to the point where this alternative would he practical. | en_US |
