Zhejiang Shaoxing Industrial Park 2 MW / 4 MWh optical storage project (commissioned in July 2021)
1 Overall project scale
• Distributed PV: 14.5 MWp (construction in three phases, rooftop BAPV/BIPV hybrid)
• Behind-the-meter energy storage: 2 MW / 4 MWh (two 0.5 MW / 1 MWh containers + one 1 MW / 2 MWh container)
• Access voltage: 10 kV grid-connected, T connected to the park power distribution room
2 Detailed parameters of energy storage system
Battery type Lithium Iron Phosphate (LFP)
Rated capacity 2 MW / 4 MWh (0.5 C)
