Contemporary Amperex Technology (CATL), a China-based lithium-ion batteries manufacturer, has installed battery energy storage system (BESS) multi-mixed energy power station as part of the Luneng Haixi Multi-mixed Energy Demonstration Project.
CATL claims that this is the first of its kind in the country, where 400MW of wind, 200MW of solar and 50MW of concentrated solar power and 100MW of energy storage system have been unified into one system on the grid.
This power station will coordinate three different renewables, with fluctuating and unstable, sources of energy and is required to respond consistently to fluctuating demand.
CATL is the exclusive battery supplier for the project and had to overcome the requirements during the product design and development stage. The company claims that it took only 17 days to test and commission the BESS to the grid.
CATL vice chairman and chief strategy officer Huang Shilin said: “The Station is the first of its kind – a multi-functional, centralized power plant integrated with an electrochemical energy storage system. Its technical reliability and affordability will promote further global deployment of different renewable energy applications.”
The company stated that the first priority while the development of an energy storage station is safety. By selecting reliable materials, the company claims to minimize the possibility of failure incidents and second damage explosion.
It also claims to be following the Potential Failure Mode and Effects Analysis (FMEA) design process to identify risks and execute risk mitigation plans during the early stages of product development, manufacturing and management for safe operation of the battery system.
The station has been installed at Golmud, where temperature varies from -33.6 to 35.5 degrees Celsius. To ensure battery performance, CATL has installed a cooling system that uses air passages and air flow designs to maintain a consistent cabinet temperature.
CATL said: “In addition, the Project has tough structural requirements, as Golmud lies in an active seismic zone, which calls for vibration and shock absorption.
“CATL’s state of the art Test & Validation Center carried out rigorous testing and simulation to prove its batteries are able to withstand a potential earthquake of magnitude 8.”
