The U.S. Department of Energy’s Office of Electricity Delivery and Energy Reliability Energy Storage Systems Program, with the support of Pacific Northwest National Laboratory (PNNL) and Sandia National Laboratories (SNL), and in collaboration with a number of stakeholders, developed a protocol for measuring and expressing the performance characteristics for energy storage systems.
The protocol was first published in 2012 and was updated in June 2014. This fact sheet highlights the most recent activities and releases related to the protocol, including the June 2014 revision and some of the latest and upcoming work related to performance and safety.
