Hitachi America and Demansys Energy reached an agreement to perform a demonstration project using Hitachi’s “CrystEna” compact container-type energy storage system in the market for frequency regulation and capacity services, and that site installation work will soon commence.
The demonstration, which is designed to confirm the benefits of using the CrystEna energy storage system for grid stabilization, will run for two years, beginning in June 2014.
Recently, 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 online.
Hitachi’s CrystEna is a complete energy storage system. The system was developed with an emphasis on long operating life, providing significant commercial value. It uses Hitachi’s control systems and power conditioning systems (PCS), and lithium-ion batteries from Hitachi Chemical Co. Its enhanced economics are due to both its compact design and system performance improvements.
Demansys is participating in frequency regulation and reserves programs throughout the Northeastern U.S., using its Grid Daemon platform to supply grid operators with highly-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.
Demansys’ Grid Daemon has been used in a 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.
