East Penn Manufacturing will design and construct an energy storage facility consisting of an array of UltraBattery™ modules integrated in a turnkey Battery Energy Storage System (BESS). In addition to the UltraBatteries™, the BESS will include a power conditioning system, a master programmable controller, and a battery monitoring system. The completed energy storage system will be designed to sell up to 3 MW of frequency regulation to PPL EnergyPlus, a designated load serving entity within PJM. In addition to frequency regulation, the system will provide demand management services to Met-Ed during specified peak power periods. These services will provide up to 1MW for 1 to 4 hours to meet the requirements of PA Act 129. The UltraBattery™ is uniquely suited to these applications because it was designed for High Rate Partial State of Charge cycling. The system is sized to maintain the battery’s state of charge between 70 percent and 30 percent for a maximum 40 percent depth of discharge for continuous regulation services. The UltraBattery™ is a hybrid energy storage device that combines an asymmetric ultracapacitor and a lead-acid battery in one unit cell. The UltraBattery™ is expected to provide the same benefits as lead-acid battery systems, such as low initial cost, full recyclability, plus increased cycle life by incorporating ultracapacitor technology within the battery. To demonstrate modularity and portability, self-contained, Containerized UltraBattery™ System will be designed and included as a subset of this project.
