New Standard Identifies Performance Requirements for Electrical Energy Storage Systems

ROSSLYN, Va., April 9, 2019— The National Electrical Manufacturers Association (NEMA) published NEMA ESS 1-2019 Protocol for Uniformly Measuring and Expressing the Performance of Electrical Energy Storage Systems. This Standard provides a set of best practices for characterizing electrical energy storage systems (ESSs) and measuring and reporting their performance.

An ESS includes a storage device, battery management system, and any power conversion systems installed with the storage device. This Standard treats all systems the same concerningtechnology, size, and rating.

“ESS 1 serves as a basis for assessing how an ESS will perform with respect to key performance attributes relevant to different applications,” said Brian Marchionini, Senior Program Manager, NEMA. “It is intended to provide a valid and accurate basis for the comparison of different ESSs. This Standard will enable more informed decision-making in the selection of ESSs for various stationary applications.”

NEMA ESS 1-2019 is available in hard copy and as an electronic download for $150 on the NEMA website.

The National Electrical Manufacturers Association (NEMA) represents nearly 325 electrical equipment and medical imaging manufacturers that make safe, reliable, and efficient products and systems. Our combined industries account for 360,000 American jobs in more than 7,000 facilities covering every state. Our industry produces $106 billion shipments of electrical equipment and medical imaging technologies per year with $36 billion exports.
