NEMA Targets Electrical Energy Storage Systems
The National Electrical Manufacturers Association has published NEMA ESS 1-2019 Protocol for Uniformly Measuring and Expressing the Performance of Electrical Energy Storage Systems. The standard provides a set of best practices for characterizing electrical energy storage systems (ESS) 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. The standard treats all systems the same concerning technology, size, and rating. Click here for more information.
