Grid Storage Solution (GSS)
A123’s Grid Storage Solution (GSS) is a flexible and fully integrated solution with a grid-ready design that can be rapidly deployed today to enable generators, utilities and grid operators to reduce costs and increase plant efficiency. With High-Rate (HR) and Long-Duration (LD) options ranging from kilowatt-scale to hundreds of megawatts, A123’s GSS can be easily configured to meet customers’ exact power and energy requirements. The modular design of the GSS system is highly portable, easily placed (easy to site and permit) and can be configured to fit in spaces that cannot accommodate traditional generation assets.
Grid Storage Solution Architecture
A123’s GSS offers a flexible, modular architecture that consists of three key components: the Grid Battery System (GBS), AEROS™ Energy Control System and Power Conversion System, which are fully integrated and grid-ready. The GSS delivers a system-level AC-AC roundtrip efficiency rating of 90 percent*.
