Recently, a project announcement was made in Ulanqab City, Inner Mongolia, unveiling the new layout of Chinese energy giants in the construction of new power systems. When Beijing Energy Group's Jingneng Electric Power and State Energy Group's Guodian Electric Power teamed up to invest 868 million yuan to provide energy storage for the local multi million kilowatt level new energy base, it was not just a simple project investment, but also a set of giant stabilizers and regulating valves tailored by the two energy national teams for the integrated wind solar thermal storage large base.

900MWh energy storage stabilizes fluctuations

The core of this announcement is a lithium iron phosphate energy storage power station with a capacity of up to 225 megawatts/900 megawatt hours. As a supporting project for the 1500 MW wind solar thermal storage integrated base in Ulanqab, this giant power bank will charge when there is surplus electricity and discharge when there is insufficient wind solar output or peak electricity consumption. The 4-hour energy storage time is sufficient to cover most of the peak shaving needs of the power grid, effectively solving the intermittent problem of relying on the weather for new energy generation and ensuring the stable transmission of tens of millions of kilowatts of electricity.

Double giants join forces to open up delivery channels

Another major highlight of the project lies in its shareholder background and supporting delivery projects. The strong alliance between Jingneng Power and Guodian Power, two flagship listed companies, provides solid funding and technological endorsement for the project. At the same time, the approved 220 kV transmission line project in April this year is simultaneously laying 133 kilometers of transmission lines and fiber optic communication networks. This not only connects the physical channel of new energy from the production base to the 500 kV collection station, but also builds an intelligent scheduling neural system to ensure that energy can be delivered and controlled.

Nearly 100 million investment leveraged integrated demonstration

The total investment of 868 million yuan, equivalent to a cost of less than one yuan per watt hour, reflects the cost competitiveness of current energy storage technology in large-scale applications. The construction period of this project is from September 2026 to September 2027, which coincides with the construction pace of the wind and photovoltaic base. Its landing marks that China's large-scale base projects are moving from simple development of wind and solar resources to a systematic operation stage of deep integration of power supply, power grid, load, and energy storage, providing a replicable Ulanqab sample for the integration of wind, solar, thermal, and energy storage across the country.Editor/Gao Xue
