Nation's first grid-side energy storage plant using lead-carbon battery technology
Recently, many parts of the country have turned on the high temperature mode, and the electricity consumption of residents has increased. During this critical period of summer, Tennant's high-performance lead-carbon batteries, which have won the China Industrial Award, play an important role. In Changxing, Huzhou, the city's "giant charging treasure" composed of a block of Tennant's lead-carbon batteries is effectively guaranteeing the safety and stability of residents' electricity consumption.
"The Pheasant City energy storage power station uses Tennant's valve-regulated high-performance lead-carbon batteries for energy storage. Take a bunch of batteries, for example, more than 5,000 battery's can do about 0.1 equalization difference, these batteries are produced from the automated production line of Tianneng Intelligent Factory, stability and consistency is very good." Zhejiang Tianwang Intelligent Energy Company senior project management engineer Pu Junwei said.
Walking into the 10 kV energy storage power station in Changxing Piancheng Street, 20,160 Tianneng batteries are neatly and orderly placed on the battery rack. The real-time status of the batteries is displayed on the control screen through the battery system.
Pu Junwei said, the energy storage power station mainly plays a "peak shaving fill in the valley" role, in the city of electricity in the valley, the energy storage battery charging energy storage; peak electricity consumption, can be stabilized discharge to fill the power gap, for the grid "relay renewal"; in the event of a sudden failure of the power grid In the event of a sudden grid failure, the battery can be replaced at millisecond speed to continue to provide stable and reliable power supply for the urban area.
The power station was put into use in May 2020, is the country's first grid-side energy storage power station using lead-carbon battery technology, located in Changxing City, using lead-carbon batteries with safe, reliable and low operation and maintenance costs, etc., the battery can be retired to achieve more than 99% of the cycle of regeneration. Assuming that each resident uses ten degrees of electricity per day on average, the power station can provide 2,600 residents with one day's electricity consumption.
Energy storage is one of the key technologies for energy transformation, and it is also the focus of Tianneng's layout. Tianneng has comprehensively laid out the grid side, power generation side, industrial and commercial user side and other key markets, Datang Lubei, South Taihu high-energy lithium, Xinfeng Reserve One Intelligent Manufacturing Base and other large projects have been put into operation, and the world's largest single lead-carbon energy storage power station running on the grid has won the "Best Energy Storage Demonstration Project Award of 2023", and the Li-ion liquid-cooled energy storage system project has been selected as one of the "Advanced Technological Innovation Projects of Zhejiang Province in 2023". The lithium-ion liquid-cooled energy storage system project was selected to be on the list of advanced technological innovation achievements of Zhejiang Province in 2023.
Tianneng will give full play to the leading advantages of the whole industry chain support and multiple technology routes to build the energy storage industry ecosystem and help the healthy development of China's energy storage industry.
