Under the guidance of the "dual carbon" target, high-energy consuming enterprises are entering an important breakthrough period in their energy transformation. Recently, Inner Mongolia Chuangyuan Metal Co., Ltd. signed a cooperation contract with Guangzhou Zhiguang Energy Storage Technology Co., Ltd. (referred to as "Zhiguang Energy Storage") for the third phase of the source grid load storage integration project. The total capacity of the first, second, and third phases of the project's cascaded high-voltage energy storage system has exceeded 1GWh, continuously breaking the industry record for the installation scale of user side structured energy storage systems.

From 2024 to present, the two parties have deepened cooperation through project construction and established a full chain partnership of "technology research and development engineering application system integration". This not only realizes the large-scale application of cascaded high-voltage energy storage technology in large-scale industrial load scenarios, but also provides a replicable industry model for large high energy consuming enterprises to achieve stable direct supply of green electricity and build a low-carbon energy system.

The cumulative scale of the third phase of deep collaboration under the policy wind exceeds 1GWh

The three phases of the project are all located in the industrial park of Huolingole City, Tongliao, Inner Mongolia, and all adopt the grid type cascaded high-voltage energy storage system independently developed by Zhiguang Energy Storage. At the time of the release of the Guiding Opinions on Promoting the Integrated Development of New Energy by the National Energy Administration, grid based energy storage has been clearly listed as a "hard indicator" for the integration of new energy into the grid. Relying on the abundant wind and light resources of the Keerqin grassland in Inner Mongolia, both sides have jointly built a green energy ecology of "wind solar energy storage" synergy.

Phase I project (Chuangyuan Metal): Completed the world's first grid type cascaded high-voltage energy storage combined with coal-fired unit black start test, successfully selected as an excellent energy storage demonstration project in Inner Mongolia.

Phase II project (Chuangyuan Ke Right New Energy): equipped with 72 battery containers and 4 grid connected cabins, with full scenario power service capabilities such as frequency regulation, peak shaving, and black start.

Phase III project (Chuangyuan Science and Technology Right New Energy): Further strengthen the closed-loop of "source grid load storage" and continuously enhance the regional power grid support capacity

The scale of the third phase energy storage construction exceeds 1GWh, marking that the project has become a leading demonstration case in the domestic user side configuration network energy storage system, providing important infrastructure support for high energy consuming enterprises to achieve large-scale green power consumption.

Network construction technology breaks through the deadlock, green power supply, hard core strength escorts industrial energy use

Behind the abundant scenic resources of the Khorchin grassland in Inner Mongolia, extreme weather conditions such as severe cold, high temperatures, and strong winds, coupled with the volatility and intermittency of new energy, pose severe challenges to the continuous production of enterprises. Especially for enterprises like Chuangyuan Metal, which have high electricity loads and high requirements for power supply reliability, how to achieve safe, stable, and efficient direct supply of new energy power has become the key to the project.

The grid type cascaded high-voltage energy storage system independently developed by Zhiguang Energy Storage actively constructs the grid voltage and frequency through the "self synchronous voltage source" control technology, with strong inertia support and wide short-circuit ratio adaptability. In the first phase of the project, the system successfully achieved black start and synchronous grid connection for the supporting coal-fired units, verifying its ability to maintain stable system operation under extreme weather conditions.

This system is equivalent to installing an 'energy buffer' and an 'emergency power supply' for the factory building, "said the project leader of Chuangyuan Metal. Through the technical advantages of the intelligent photovoltaic energy storage network type cascaded high-voltage energy storage system, which is" power station to simplicity, network to strength, efficient to profitability, and extremely safe, "it can effectively improve the green power consumption rate. Even in the face of sudden drops in wind power output or fluctuations in the power grid, the system can still respond quickly, effectively avoiding huge losses caused by production interruptions, and truly achieving the goal of "no discount for wind and solar power generation, and continuous supply of green electricity".

Highlighting the benchmark effect and leading the industrial zero carbon transformation

The cooperation between Zhiguang Energy Storage and Chuangyuan Metal explores a new path for the coordinated development of green, low-carbon, and efficient production through the deep coupling of "grid type energy storage+wind and solar power generation+industrial load". While maximizing the consumption of clean energy, it effectively reduces the electricity cost of enterprises and enhances the reliability of power supply.

This model has set an innovative example for high energy consuming enterprises nationwide to promote energy transformation. Against the backdrop of the deepening of the dual carbon strategy, there is an urgent need for green electricity substitution in high energy consuming industries such as steel, electrolytic aluminum, and alloys. The application of grid type cascaded high-voltage energy storage systems is gradually becoming the "golden key" to solving the problem of reliable direct supply of new energy.

The relevant person in charge of Inner Mongolia Chuangyuan emphasized that the third phase cooperation is a key measure for enterprises to practice green development. In the future, with the full operation of the project, this energy solution covering the entire chain of "power generation storage electricity consumption" will continue to release green energy in the Khorchin grassland, accelerate the transformation of regional energy structure towards clean and low-carbon, jointly create a benchmark and industry model for direct green power supply, and practice the "dual carbon" goal with practical actions.Editor/Yang Meiling
