Application of a uniform testing protocol for energy storage systems

Rosewater, David M.; Scott, Paul; Santoso, Surya

Methods for benchmarking and comparison can either limit or accelerate the adoption of emerging energy storage technologies on the grid. This paper assesses the efficacy of the methods in the U.S. DOE Protocol for Uniformly Measuring and Expressing the Performance of Energy Storage to remove barriers to the technology's acceptance. The protocol enables standardized data collection to compare different technologies for energy storage applications fairly. We apply the relevant portions of the protocol to a 1-megawatt lithium-ion battery system to provide a critical assessment of procedures and methods it stipulates. Field experience and data will be invaluable to standards development organizations as they begin to consider these methods for codification.
