The warm sun on the island in winter is still the same, and in the past few days, the "windmill forest" in the northern sea area of Pingtan Island has stood proudly in the wind, sucking wind and spitting electricity. In Luliao Village, Junshan Town, which is about 7 kilometers away from the Yangtze River Ao Wind Power Landscape Area, the construction of key projects is in full swing. Pingtan Comprehensive Experimental Zone Urban Distribution Network Power Supply Capacity Improvement - Shared Energy Storage Power Station Project (Phase I) (hereinafter referred to as "Pingtan Shared Energy Storage Power Station") is located here. During the Spring Festival, more than 20 workers were still stationed at the project site.
As the first 220 kV energy storage power station in Pingtan City, the total land area of Pingtan shared energy storage power station is about 40 acres, and the investment is about 66.6 billion yuan. The project mainly arranges 1 4-storey comprehensive building, 1 1-storey power distribution device building, 1 batch of electrical equipment, a total of 72 battery containers and 40 converter and booster integrated machines, and 1 new 220kV high-voltage transmission line of about 2 kilometers.
This is the first large-scale centralized shared energy storage power station in Fujian Province, and it is also the electrochemical energy storage power station with the largest single capacity in Fujian Province. Since the start of construction in June last year, the project has set the goal of "planning to be connected to the grid and put into operation in 2024". "Race against time to rush the progress, and strive to complete the capping of the complex building by the end of March. Zhang Yongming, deputy general manager of the project construction unit and Pingtan Comprehensive Experimental Zone Energy Storage Technology Co., Ltd., said.
The project site during the Spring Festival is much quieter than usual. The reporter saw at the scene that only a few engineering vehicles were shuttling back and forth, and workers wearing hard hats were climbing up and down for construction work. The prototype of the energy storage unit made of cement has appeared, and the comprehensive building has put on "green clothes". "Inside the protective net, the construction team is curing the newly poured concrete to accelerate its hardening and strength growth. Zhang Yongming explained.
Formwork worker Lin Xiaohong spent the New Year in the field for the first time. He is from Jiangxi and has many years of experience in formwork structure construction. "In the pre-construction of construction projects, concrete pouring is an indispensable step, and wood formwork is an auxiliary tool when pouring concrete. Talking about the reason for staying, Lin Xiaohong said with a smile: "In order to keep the construction progress of the project unabated, the formwork structure has to be built almost every day, and everyone has to go back for the New Year, so I should stay." ”
At the beginning of this year, the National Energy Administration released a list of national new energy storage pilot demonstration projects, and Pingtan shared energy storage power station became the only project selected in our province. When the good news reached the construction site, the workers were more motivated. "From the project manager to the construction team, we arranged a detailed construction plan during the Spring Festival, and held daily production coordination meetings to discuss the progress of the project. Zhang Yongming said.
It is reported that the shared energy storage power station will focus on the national "double carbon" strategic goal, optimize the integration of wind power development, regional power grids, emerging industrial parks and other projects, explore the creation of an integrated demonstration area of "source, grid, load and storage", and help the construction of Pingtan "zero carbon island". After completion, it will help Pingtan clean energy power generation enterprises to provide local shared energy storage facilities, effectively alleviate the blockage of power transmission channels, improve wind power absorption capacity, implement the "Electric Fujian" action plan, and boost the development of Fujian's energy storage industry. "It can not only provide supporting energy storage for the development of Pingtan offshore wind power industry and improve the capacity of wind power consumption, but also provide flexible adjustment resources such as peak regulation, frequency modulation, and black start for the island-type regional power grid to ensure the guaranteed power supply. Zhang Yongming said.
At the end of the interview, the reporter looked at this giant shared "charging treasure" when he left, and it is foreseeable that in the future, it will be charged and stored in the valley, and discharged and regulated in the peak, with the support of strong energy storage technology, to "shave the peak and fill the valley" for the power grid. The office area and dormitory not far from the construction site are hung with lanterns, Spring Festival couplets, blessing characters, etc. Lin Xiaohong's words were recalled in my ears: "Stand on this shift for the Spring Festival and have a Chinese New Year's Eve dinner with my brothers." When the project is completed, I will go back to my hometown to reunite with my family as soon as possible! (Fujian** reporter Lin Xia).
