The layout of new energy on the grassland continues to accelerate, and this long-term energy storage project with a total investment of 4.8 billion yuan has reached a critical juncture. The list of candidates for the PC general contracting bid has been publicly announced, and multiple strong units are competing on the same stage to create a stable and flexible power regulation carrier for this energy base, promoting efficient consumption of wind and solar resources.

The list of winning bidders has been released

The public announcement this time is about the 1 million kilowatt and 6 million kilowatt hour power side energy storage PC project in Chayou Zhongqi, which adopts the procurement and construction general contracting mode. The scope of work includes equipment procurement, construction, installation, commissioning, testing, commissioning, and supporting coordination services. The first candidate for winning the bid is a consortium composed of multiple enterprises, with a bid price of 466680 million yuan, equivalent to a unit price of 0.7778 yuan per Wh. The second candidate for winning the bid is China Electric Power Construction Group Guiyang Survey and Design Institute Co., Ltd., with a bid price of 469152556947 million yuan, equivalent to a unit price of approximately 0.7819 yuan per Wh.

Energy storage empowers the power grid

The project belongs to six hour long-term energy storage, with self raised funds of 4.8 million yuan, equivalent to a unit price of 0.8 yuan per Wh, and a total capacity of 1000MW6000MWh. It adopts liquid cooled lithium iron phosphate energy storage technology and is equipped with a 220kV booster station. The energy storage device is connected to the booster station through 150 35kV collection lines, and then connected to the 500kV Chayou Middle Transformer through one 220kV line. After the project is completed, it can undertake peak shaving and frequency regulation tasks, alleviate the pressure on the power grid during industrial and commercial electricity consumption periods, and improve energy utilization efficiency.Editor/Min Jing
