On January 25, one of the largest electrochemical energy storage projects in China—the Hebei Jidian Longhua Independent Energy Storage Station—officially met the conditions for grid connection. This marks a significant step forward in the development of new energy in the Beijing-Tianjin-Hebei (Jing-Jin-Ji) region, adding a powerful new "energy storage system" to the grid.
Just two months earlier, the 200 MW Photovoltaic and Energy Storage Integrated Project in Weichang, Chengde, Hebei, began operation, supplying clean electricity to the Beijing-Tianjin-Hebei area. Covering more than 7,000 acres, the project includes 61 power generation arrays and over 360,000 photovoltaic panels. It is expected to generate 320 million kWh of electricity annually, enough to meet the yearly needs of over 100,000 households. Additionally, the supporting wind farm features 50 wind turbines, each with a 6 MW capacity. This farm is projected to produce 670 million kWh of green energy per year, saving 204,400 tons of standard coal and reducing carbon dioxide emissions by approximately 545,300 tons.
As Chengde’s "Two Stations, One Channel" infrastructure project progresses, renewable energy is being transmitted at full capacity to the power-hungry regions of Beijing, Tianjin, and Hebei. Wang Hongliang, Deputy Director of the Development and Planning Department at State Grid Chengde Power Supply Company, explained that by 2024, the Chengde power grid will integrate 8.59 million kW of new energy, accounting for 43% of the total installed wind and solar power in the city. The majority of this green electricity will be transported through four 500 kV transmission lines to Tangshan, from where it will be distributed to the Beijing-Tianjin area.
Wind and solar energy often face the challenge of supply and demand imbalance—excess power during low-demand periods and shortages during peak times. To resolve this, the Hebei Jidian Longhua Independent Energy Storage Station was developed. During off-peak hours, surplus wind and solar energy will be stored using lithium iron phosphate batteries. During peak periods, the stored energy will be released, ensuring a stable and reliable supply of green power. By the end of March, the 300 MW/1,200 MWh energy storage facility is expected to be fully operational, meeting nearly half of Chengde's energy storage needs for renewable energy.
