NEC Corp. announced that it is working with the Electric Power Research Institute, Inc. (EPRI) to conduct joint field trials of an electricity storage system using NEC’s lithium-ion battery.

In the first phase of the testing, a 25kW system provided to EPRI by NEC will be tested as an initial step toward future smart grid applications. Follow-up electric utility demonstrations of larger 1MW systems could be possible as part of an EPRI - U.S. electric utility industry research collaborative.
