QuESt is a free, open source, Python-based application suite for energy storage simulation and analysis. It was developed to bring Sandia energy storage analytics research tools to the desktop. QuESt currently consists of three distinct yet interconnected applications that individually and collectively will help project engineers and researchers evaluate energy storage systems for different use cases.

DOE Global Energy Storage Database provides research-grade information on grid-connected energy storage projects.
