Lead Handbook development and integration support has been provided in this joint EPRI and DOE project to provide potential utility end-users and technology developers with a balanced appraisal of economic incentives for deploying advanced energy storage systems in T&D applications. A Supplement to the Handbook addresses wind power applications. The Handbook assesses the potential benefits and costs of energy storage on the national and corporate level and provides a "technology-neutral," comparative framework that utilities can use to formulate detailed application and site-specific assessments of specific technologies. The Handbook details the status, capabilities and limitations, and costs and benefits of the leading available storage technologies: lead-acid, nickel-electrode, and sodium-sulfur modular batteries; zinc-bromine and vanadium redox flow batteries; superconducting magnetic energy storage; flywheels; electrochemical capacitors; and compressed air energy storage. Each technology is ranked as to suitability, and compared with other technologies, in one or more of 14 different utility T&D system applications. Our role in this effort included lead responsibility for the characterization of the applications and incentives, the development of the economic analysis methodology, the detailed assessment of select storage technologies and integrated Handbook preparation. The end product advances the familiarization of energy storage options and provides a framework for users to make informed decisions on the relative merits of emerging technologies applied to specific applications.
