Recently, Ningxia Yuanrun New Energy Technology Co., Ltd.'s provincial key energy storage project, the 100MW/400MWh shared energy storage power station, officially started construction in the energy load core area. The total investment of the project is about 2 billion yuan, and it is planned to achieve full capacity grid connected operation by the end of 2025. As a key supporting project for the construction of a new regional power system, the power station will become one of the largest and most technologically advanced shared energy storage platforms in the local area after completion, providing core guarantees for the consumption of new energy such as wind power and photovoltaics, as well as peak shaving and frequency regulation of the power grid.

Project Core: Technological Leadership and Breakthrough of "Sharing" Mode

The shared energy storage power station adopts an operation mode of "centralized construction, multi-party sharing, and on-demand scheduling", breaking the traditional "one-to-one" binding restrictions of energy storage projects. It can simultaneously serve 5 new energy power stations (with a total installed capacity of over 1.2GW) and 3 local power supply companies in the surrounding area, achieving efficient reuse of energy storage resources.

In terms of technical configuration, the project focuses on improving both security and economy:

Energy storage system: Lithium iron phosphate energy storage batteries are selected, combined with liquid cooling temperature control technology, which can control the temperature fluctuation of the battery operation within ± 2 ℃, increase the cycle life to more than 12000 times, and reduce energy consumption by 30% compared to traditional air-cooled systems;

Control platform: equipped with a self-developed "source grid load storage" collaborative dispatch system, capable of responding to power grid dispatch instructions in real time, with a frequency response time of ≤ 100 milliseconds, reaching the top level in China;

 Safety design: Build a three-level fire protection system of "battery cabin station", equipped with hydrofluorocarbon (HFC) gas fire extinguishing devices and 24-hour AI inspection robots, to eliminate the risk of thermal runaway from the source.

Strategic Value: Triple Empowerment of Regional Energy Transformation

From the perspective of new energy consumption, the 400MWh large capacity energy storage capacity of the power station can effectively stabilize the output fluctuations of surrounding wind and photovoltaic power. It is expected to increase the new energy consumption rate by about 8 percentage points annually and reduce the amount of abandoned wind and solar power by more than 150 million kilowatt hours; From the perspective of power grid security, its 100MW rated power can meet 5% of the load regulation demand during regional electricity peak periods, and can provide up to 4 hours of emergency power supply support in extreme weather conditions, greatly improving the resilience of the power grid; In terms of economic benefits, in addition to obtaining income through peak shaving and frequency regulation, the project can also provide "energy storage+backup power" services to surrounding industrial parks, with an expected full life cycle return rate of 8% -10%, providing a replicable model for the commercial operation of energy storage projects.

According to the person in charge of the project contractor, the next step will be to adopt a "modular construction+digital control" mode to ensure that the project is connected to the grid three months in advance. The construction of this power station not only fills the gap in regional high-capacity shared energy storage, but also marks the acceleration of the transformation of the domestic energy storage industry from "single function" to "diversified sharing", injecting strong impetus into the construction of a new power system.

Industrial linkage: activating a new ecosystem of upstream and downstream collaborative development

The construction of the shared energy storage power station is forming a strong driving effect on the energy storage industry chain. At present, the project has reached cooperation agreements with three leading domestic energy storage battery companies and two energy storage inverter (PCS) manufacturers. The localization procurement rate of core equipment exceeds 90%, directly driving the output value growth of surrounding energy storage equipment assembly, cable manufacturing and other supporting industries by about 500 million yuan. Among them, the liquid cooled energy storage container customized for the project can achieve "plug and play" through standardized design, and can be replicated and applied to other large-scale energy storage projects in the future, promoting the upgrading of energy storage equipment manufacturing towards "standardization and modularization".

At the same time, the project also collaborates with local universities and research institutions to establish a "Joint Laboratory of Energy Storage Technology", focusing on tackling technical challenges such as optimizing the lifespan of long-term energy storage batteries and controlling the stability of energy storage systems in extreme environments. It is expected to cultivate over 200 professional and technical talents in energy storage. This "project driven+industry university research collaboration" model not only provides technical support for projects, but also helps the region build a complete industrial ecosystem from energy storage technology research and development, equipment manufacturing to project operation.

This policy support model is highly in line with the requirements of the national "Guidelines for the Development of New Energy Storage" to encourage innovation in shared energy storage models and improve supporting policies. According to industry data, since 2025, 15 provinces in China have introduced special support policies for shared energy storage, covering multiple dimensions such as subsidies, grid connection, and electricity prices, promoting a 45% year-on-year increase in investment growth rate for shared energy storage projects. The implementation of this power station is a typical case of policy dividends and market demand driven by both directions, and also provides a reference path for the development of shared energy storage in other regions through a combination of policies and projects.Editor/Bian Wenjun
