The world’s largest source network load storage demonstration project invested and constructed by the Three Gorges Group-the Three Gorges Ulanchabu New Generation Grid-Friendly Green Power Station Demonstration Project. The energy storage system has recently been tendered and the first phase of 70MW/140MWh smart storage will be provided by Envision Energy. Can system.

The total installed capacity of the Ulanqab "source-network-load storage" demonstration project is 3.1 million kilowatts, including 2.8 million kilowatts of wind power, 300,000 kilowatts of photovoltaics, and supporting energy storage facilities of 880,000 kilowatts × 2 hours. It is also the first domestic “source-network-load storage” "Demonstration project. After the project is completed and put into operation, it will help improve the overall efficiency of the local power system and the coordination of source and network loads, improve the level of clean energy consumption, enhance the peak load protection capability of the regional power grid, and explore grid-side energy storage and direct green power supply Wait for the new model. The Three Gorges Ulanqab New Generation Grid-Friendly Green Power Station Demonstration Project is located in Siziwang Banner, Ulanqab, Inner Mongolia. The Three Gorges Group invested and constructed in three phases. Envision Energy provided 22 sets of 3.35MW/6.7MWh smart energy storage units for the first phase of the project. The total capacity is 70MW/140MWh. In addition, Envision Energy has delivered a 100MW smart wind turbine for the demonstration project, using wind and storage technology solutions to support the construction and operation of the country's first "source network load storage" project.

Safety is the lifeline of energy storage projects. Envision Energy adopted the nation's first "cluster-level perfluorohexanone + water spray" fire protection program in this project, and set up an independent fire control network function to greatly improve the fire safety of energy storage products. As the earliest energy storage product used in large-scale "source-network-load storage" projects, the Envision Smart Energy Storage System provides rapid power response to the grid, improves the power supply capacity of the system during peak hours, and ensures the safety of energy use on the load side.

At the 10th International Energy Storage Summit and Exhibition in April 2021, CSA Group, an international standard certification authority, issued UL9540A international standard certification to Envision Energy. Envision Energy became the first batch of domestic companies that passed the latest version of UL9540A (fourth edition). The provider of energy storage system solutions signifies that Envision's smart energy storage products have the ultimate safety and quality assurance. The Envision Smart Energy Storage System has also obtained certifications such as the IEC62619 international energy storage battery standard, GBT36276 national standard for lithium-ion batteries for power storage, and the Thai power grid PEA standard.
