The $1.5M system will be installed at corporate headquarters at 201 Washington Road in Princeton, NJ, and connect to the PSE&G electric grid. In addition to a 200 kilowatt solar array, the installation will include a 200 kwh energy storage system consisting of large-format lithium-ion batteries manufactured by International Battery in Pennsylvania using their water-based process.
The energy storage system will be housed in a 20 ft shipping container and is expandable to 1 MWh of storage. The system will be controlled and connected to the electric grid using Princeton Power System’s Grid-tied Inverter (GTIB) product, manufactured in NJ. The installation will demonstrate advanced smart grid functionality including microgrid operation, demand response, frequency regulation, and power dispatch.
“Integrating large amounts of alternative energy sources like solar and wind into the electric grid will require improved controls and electronics, and this in turn will make distributed generation much more valuable and effective,” stated Darren Hammell, Executive Vice President of Business Development at Princeton Power. “Our goal is to show that this is possible and cost-effective today, using available technologies, while creating jobs and doing our part to help the environment.”
When commissioned, the solar array will produce sellable Solar Renewable Energy Certificates (SRECs) and offset a portion of the building’s energy usage. The project is financed in part by the State of New Jersey’s Clean Energy Manufacturers Fund, which is helping Princeton Power Systems to expand its state-of-the-art research and development and manufacturing facilities for next-generation power electronics.
