The demonstration involves the installation of a Hitachi CrystEna system in New Jersey, not far from Philadelphia. It also has the ability to provide capacity services and plans to do so from the New Jersey-based demonstration project.ĭemansys will be responsible for overall coordination of the new demonstration project. Its enhanced economics are due to both its compact design and system performance improvements.ĭemansys is participating in frequency regulation and reserves programs throughout the Northeastern US, using its Grid Daemon platform to supply grid operators with services involving real-time control and management of energy storage and behind-the-meter energy assets. It uses Hitachi’s control systems and power conditioning systems (PCS), and lithium-ion batteries from Hitachi Chemical. Hitachi’s CrystEna was developed with an emphasis on long operating life, providing significant commercial value. Throughout the US, numerous new entrants, including storage resources, are demonstrating their ability to provide frequency regulation and capacity services. 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 on-line. 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. The capacity services market is an auction through which grid operators secure a sufficient supply of capacity several years into the future from supply and demand-side resources.
