Energy Storage Project Roundup — China Energy Storage Alliance

What exactly is happening in China? The world's highest elevation storage facility began operations, Chinese manufacturer GCL announced plans for a 500 MWh project, and what will be the world's largest Zn-Br flow battery components center was announced, to name a few. CNESA has prepared a roundup of some of China's latest energy storage projects that either came online or were announced this past month.

Tibet Shuanghu County Renewable Energy Network (Now Operating)

  
    Location:
    Shuanghu County, Tibet
  
    Companies Involved:
    Owner: Power Construction Company of China – Northwest Engineering Storage providers: Corporation Clou Electronics Co., Sungrow Power
  
    Key Specs:
    13 MW solar PV station, 24 MWh battery storage system, 1.5 km of electricity lines and grid integration system.
  
    Clou Electronics won 3 MW/10.08 MWh in tender for off-grid energy storage and container system (6 total containers) to provide frequency modulation and voltage control for the system. Sungrow Power will provide the entire 13 MW of PV inverters and header boxes, Samsung SDI-Sungrow will provide 7 MW of storage inverters and a 13.6 MWh Li-ion battery system.
  
    Notes:
    The project, situated in Shuanghu County, Tibet, the world’s highest elevation administrative district, also represents the world’s highest elevation solar project. The project is part of an effort to power the region with a history of unstable electricity service, with residents relying largely on diesel generators and yak butter lamps, along with burning coal for heat during the cold winter months, resulting in negative health impacts on residents. The extreme elevation, high wind speeds, and adverse rain/snow conditions pose immense challenges for weatherizing the energy storage system equipment. Furthermore, the location only experiences an average 80 days per year without frost, thereby severely shortening the construction period.

Kehua Technology Large Scale Off-Grid PV Storage Project (Now Operating)

  
    Location:
    An oil field in Uzbekistan
  
    Companies Involved:
    Kehua Technology Co.
  
    Key Specs:
    1.2 MW distributed solar PV, 1 MWh lead acid colloid battery system
  
    Design includes inverters, battery container boxes, power distribution equipment. Principal functions: electricity generation and distribution, with Kehua providing system controls.
  
    Notes:
    System operations are divided into three modes:
  
    1) Solar generation ≥ load requirements: solar PV cells will provide electricity and diesel generators will stop running. The off-grid inverters will convert the solar electricity for use in the oil field and will charge onsite storage batteries.
  
    2) Solar generation < load requirements: [Stage 1]; solar cells and battery storage will provide electricity together. [Stage 2]; When  battery charge is low, this will initiate diesel generators to begin providing the oil field with power, solar energy will be used instead for battery charging.
  
    3) No solar generation and insufficient battery charge: diesel generators provide the oil field with electricity without charging batteries. This guarantees that the critical equipment in the oil field can safely and stably continue operations.

*GCL's E-KwBe currently comes in multiple colors of 2.5 kWh and 5.6 kWh models.*

GCL has called itself the “One-stop solution for comprehensive energy integration.” With its E-KwBe Li-ion battery model is hailed by many as the biggest threat to Tesla’s PowerWall battery systems (and cheaper too), their motto might be more than just marketing puffery. The Chinese manufacturer recently reached an agreement with the Australian wholesaler One Stop Warehouse to distribute another 1,000 E-KwBe units in October. The first batch of 1,000 units was already successfully delivered to Brisbane in September. Currently E-KwBe comes in 2.5 kWh and 5.6 kWh models. New documents show the company is also in preparations for developing a 500 MWh battery storage project. GCL recently raised nearly US$500 million in capital, of which it will siphon US$14.5 million into the the 500 MWh project. Total project investment for the 500 MWh project is estimated to be US$26 million, and is expected to take a year to complete.

China’s First Off-Grid Solar + Storage EV Fast Charging Station (Now Operating)

  
    Location:
    Dongguan Yujia Industrial Park, Dongguan, Guangdong Province
  
    Companies Involved:
    Designed by Beijing Juneng Photoelectric Technology Co.
  
    Key Specs:
    Solar PV station will generate around 80 MWh daily, the storage station will have a capacity of 20 kW/100 kWh
  
    Notes:
    High voltage DC electricity from the PV will charge the Li-ion battery storage system, and high voltage DC will also provide charge for electric vehicles. Taking the Beijing Automobile Works EV160 model electric car as an example, the car is equipped with a 24 kWh battery. Charging from 30% to 80% capacity requires 12 kWh. On a clear, sunny day, this charging station could charge 6-7 EV160 models, each car requiring 40 minutes charging time.
