Hitachi America, Ltd. and Demansys Energy, Inc. have completed construction and commissioning of a 1MW Lithium Ion energy storage facility using Hitachi’s CrystEna compact container-type energy storage system. The demonstration project is located in Somerdale, N.J.
Energy storage is an emerging disruptive technology in the power grid management space because it enables integration of larger quantities of intermittent renewable generation sources like wind and solar, real time stabilization of the grid at a lower cost than using traditional generators, and it can shift loads to avoid peak demand on strained transmission and distribution facilities deferring costly utility investment.
Demansys and Hitachi had an agreement to perform a demonstration project using Hitachi’s CrystEna in the market for frequency regulation and capacity services last year. Demansys managed this demonstration project that involves the installation of a Hitachi CrystEna system in New Jersey, not far from Philadelphia. To verify the system’s effectiveness for grid stabilization, the project will collect data over a two year period, including a capacity pilot project with PJM's Interconnection and frequency regulation operation in PJM, the USA’s largest independent grid operator. The project has started to further evaluate energy storage systems and to verify system reliability and effectiveness with the aim to engage in a large deployment in the U.S. ancillary services market.
Hitachi supplied the energy storage system, which is the first North American deployment of its CrystEna compact container-type energy storage system and includes the lithium ion batteries, power conditioning system, battery management system, and cooling and fire suppression systems all in one 45 ft shipping container. Hitachi is using this installation to prove its product in the PJM market in the US and to collect data that will be used to further improve the offering.
Demansys developed the facility including managing the interconnection process with the Regional Transmission Operator, PJM Interconnection, engineering the facility, procuring the balance of plant equipment, and supplying all of the SCADA and control systems necessary to remotely operate the system. Demansys also represents the system in the PJM energy market, bidding the facility on an hourly basis and connecting the PJM grid control system to the battery enabling it to respond to real time control signals from the grid.
