The Zhangbei National Wind and Solar Energy Storage and Transmission Demonstration Project will eventually grow to include 500 MW of installed wind capacity, 100 MW of installed solar PV capacity and 110 MW of energy storage with an overall investment of 12 billion RMB (1.89 billion USD).

The project currently includes a total of 14 MW of lithium-ion batteries and a vanadium redox flow battery:
(I) 6 MW / 36 MWh Lithium Iron Phosphate batteries (BYD Auto)
(II) 4 MW / 16 MWh Lithium-ion batteries (Amperex Technology Limited (ATL))
(III) 3 MW / 9 MWh Lithium-ion batteries (China Aviation Lithium Battery Co., Ltd.)
(IV) 1 MW / 2 MWh Lithium-ion batteries (Wanxiang Group)
(V) 2 MW / 8 MWh Vanadium Redox Flow Battery (Prudent Energy)
Note: The 5 National Wind and Solar Energy Storage and Transmission Demonstration Project entries in the DOE Energy Storage Database correspond to the 4 lithium-ion battery systems and 1 vanadium redox flow battery system. Original plans to include 4MW of sodium sulfur batteries have been delayed over safety concerns.

Energy storage applications include wind solar and other renewable energy integration, frequency regulation and voltage support. The project is focused on using battery energy storage to enable interactive management of the electric power grid.
