河北定州多能互补提速 200MW/400MWh独立储能电站年送绿电1.25亿度Hebei Dingzhou speeds up multi-energy complementarity; 200MW/400MWh independent energy storage power station delivers 125 million kWh of green electricity annually

In August this year, the 200MW/400MWh independent energy storage power station in Dongting Town, Dingzhou City, officially connected to the grid and commenced operation, continuously feeding clean green electricity into the southern Hebei power grid. According to calculations, the power station is expected to deliver 125 million kWh of clean electricity annually, reduce carbon dioxide emissions by 98,200 tons, and contribute to regional pollution reduction, carbon reduction, and the tangible results of green transformation.

This large-scale 200MW/400MWh grid-side independent energy storage power station was invested and constructed by Jiantou Energy Storage (Dingzhou) New Energy Technology Co., Ltd., a joint venture established by Hebei Construction Investment Group and Dingzhou Construction Investment Holding Group Co., Ltd. It is equipped with a domestically mature and advanced 314Ah lithium iron phosphate energy storage system, accompanied by a constructed 220kV booster substation and a 6.5-kilometer 220kV delivery line. The entire station relies on large-scale integrated equipment layout and full-process intelligent management to achieve efficient power storage, precise dispatching, and stable output, becoming a core carrier for green electricity regulation and peak shaving in the central-southern Hebei region.

"The power station is equivalent to a large power bank for the grid," explained Zhang Junniu, General Manager of Jiantou Energy Storage (Dingzhou) New Energy Technology Co., Ltd. During periods of low electricity demand, it stores clean green electricity such as wind and solar power; during peak demand, it delivers electricity steadily, responding to power adjustment needs within milliseconds. This can effectively solve the problem of fluctuations in renewable energy generation, greatly improve the local utilization rate of renewable energy, and enhance the flexibility and safety margin of grid operation.

The successful implementation of renewable energy storage is a vivid reflection of Dingzhou's energy transition and is a key component in the city's effort to build a diversified and coordinated energy system. In recent years, Dingzhou has deeply practiced the "dual carbon" strategic plan, seized opportunities for renewable energy transformation and development across the province, leveraged its geographical advantages, industrial base, and resource endowments, and coordinated the development of multiple sectors including photovoltaic, wind, renewable energy storage, hydrogen, and biomass energy. The city is accelerating the construction of a new modern energy system that is multi-energy complementary and collaboratively efficient, integrating "solar, wind, storage, hydrogen, and biomass."

Improving the quality and expanding the capacity of the photovoltaic industry. Dingzhou is promoting residential and commercial distributed photovoltaic projects across the city, steadily expanding photovoltaic power generation capacity and continuously broadening coverage. As of now, the total grid-connected photovoltaic power generation capacity in the city has reached 668 megawatts.

Accelerating breakthroughs in the wind power industry. In the city, the 850 MW wind power project with a total investment of 4.85 billion yuan is progressing in an orderly manner. The first phase, a 50 MW project, has already been fully connected to the grid, and the main construction of the second phase, a 200 MW project, is steadily advancing. The hydrogen energy industry is leading in demonstration projects. Relying on the leading advantage of Xuyang Group, the country’s first commercial 5-ton/day hydrogen expansion refrigeration liquefaction project has been constructed and successfully put into operation, filling the domestic gap in civilian liquid hydrogen technology and laying a solid industrial foundation for building an important hydrogen energy supply base in the Beijing-Tianjin-Hebei region.

Biomass energy recycling and efficiency enhancement. Building on the resource advantages of a major agricultural city, Dingzhou has vigorously promoted comprehensive utilization demonstration projects for biomass energy, advancing the efficient use of agricultural organic waste such as straw and livestock and poultry manure through resource conversion, reduction, and harmless treatment. Currently, the city can handle 566,000 tons of crop straw and 186,000 tons of livestock and poultry manure annually, producing 10.15 million cubic meters of natural gas and generating 110 million kilowatt-hours of electricity, with residual heat supplying 67,000 square meters of heating area.

At the same time, the Gaoxin Jiantu Zhunen Green Power Direct Connection Project was successfully selected as one of the first batch of green power direct connection projects in Hebei Province for 2026, further smoothing the entire chain of green power production, consumption, and utilization, and helping upgrade green energy use in the industrial sector. The collaborative efforts of diverse energy sectors continue to expand new space for energy transformation at the county level, and the renewable energy industry has become a new green engine for promoting high-quality economic and social development across Dingzhou.

Dingzhou City stated that it will continue to optimize the development layout of the energy industry, deepen the multi-energy complementary and collaborative development model, and implement key tasks such as the construction of renewable energy projects, securing necessary resources, policy implementation, and support services. It will accelerate the adjustment of the regional energy structure and expand the green industry cluster, injecting green momentum into high-quality economic and social development through comprehensive and multi-level energy green and low-carbon transformation.
