An energy storage project for grid stabilization to harmonize intermittent resources will run for two years in New Jersey starting in June.
Hitachi America and Demansys Energy will perform the project using Hitachi’s CrystEna compact container-type energy storage system in the market for frequency regulation and capacity services.
Regulators, grid operators, utilities, and research organizations have projected the need for additional grid storage systems to help ensure reliable power system operation as an increasing percentage of intermittent energy sources, such as wind and photovoltaic power generation, are brought on-line.
CrystEna uses Hitachi’s control systems and power conditioning systems (PCS), and lithium-ion batteries from Hitachi.
Demansys is participating in frequency regulation and reserves programs throughout the Northeastern US, using its Grid Daemon platform to supply grid operators with reliable services involving real-time control and management of energy storage and behind-the-meter energy assets. It also has the ability to provide capacity services and plans to do so from the New Jersey-based demonstration project.
The demonstration involves the installation of a Hitachi CrystEna system in New Jersey. The demonstration will collect data over a two-year period, including a capacity pilot project with PJM and frequency regulation operation in PJM, the US’s largest independent grid operator. The demonstration will be used by Hitachi to further evaluate its energy storage systems and to verify the systems’ reliability and effectiveness with a view to future commercialization.
Demansys’ Grid Daemon has been used in a diverse range of commercial and industrial applications. Since October 2012, the company has participated in a pilot program in the New England frequency regulation market that controls consumer loads in order to regulate frequency without the use of generators.
