Energy storage company Younicos has signed an agreement with strategic partner Panasonic to design and build a solar-plus-storage system at Pena Station NEXT in Denver, which includes the operations hub for Panasonic Enterprise Solutions Co. and Panasonic CityNOW.
Younicos says the project calls for four of its Y.Cube “storage-in-a-box” systems to be installed at the Panasonic facility. The 1 MW storage resource, which will be connected to the Xcel Energy power grid, will provide frequency regulation, solar grid integration through ramp control, grid peak shaving, passive energy arbitrage, and backup power – enabled by Younicos’ Y.Q storage control software.
According to Younicos, this multi-mode operating capability will enable Panasonic, Xcel Energy and other microgrid stakeholders to derive maximum benefits from Xcel’s 1.6 MW solar PV system sited on a parking structure nearby, along with 259 kW of PV on the building’s rooftop.
“The solar-plus-storage microgrid is an anchor, not just of Panasonic’s new Denver operations hub, but also for the broader Pena Station NEXT development, which is a 400-acre, smart and sustainable transit-oriented development in Denver,” said Jamie Evans, managing director of the energy solutions group at Panasonic Enterprise Solutions Co. “We are excited to partner with Younicos and Xcel Energy to bring this innovative project to life.”
The Y.Cube consists of two sub-enclosures, one each for the power conversion system and DC battery block. The controls are embedded in the PCS and communicate directly with the battery system, bypassing the need for additional battery-to-PCS communication interfaces, according to Younicos. The company notes that the Y.Cube is available in 250 kVA or 500 kVA modular building blocks that can be deployed individually in smaller applications or combined to create multi-megawatt systems.
