On January 16, China's largest behind-the-meter (BTM) energy storage project, jointly built by Great Power and Sichuan Zhongfu, was officially connected to the grid and put into operation. Boasting a scale of 107.12MW/428.48MWh, it is also the first large-scale BTM energy storage project in the aluminum industry. Upon grid connection and operation, it will help the industrial park substantially cut power consumption costs, improve power supply reliability, and set a benchmark for the green and low-carbon transformation of energy-intensive industries in Guangyuan, Sichuan Province, and across China.
For this BTM energy storage project, Great Power delivered a reliable, durable, smart and efficient overall solution for the energy storage power station. It adopts the Great Com liquid-cooled energy storage system with high safety, high energy efficiency and long cycle life, and is equipped with the Great E intelligent operation management system.
Meanwhile, by applying electrolysis energy storage DC-connected technology jointly developed by both parties — a pioneering innovation in the aluminum industry — this technology can be combined with PV to form a "PV + energy storage coupled" DC direct supply system, significantly reducing power losses, enhancing economic benefits, and achieving efficient transformation of technological innovation into low-carbon transition practices.
Against the strategic backdrop of Guangyuan City striving to build itself into China’s Green Aluminum Hub, aluminum industry, which is an energy-intensive sector, has long been plagued by soaring power costs, difficulties in consuming green power, and mounting carbon emission pressure. Closely aligning with the core demands of the industry and the project, Great Power relied on its profound technological expertise and mature project delivery system in the energy storage sector. Despite complex construction conditions, the full-capacity grid connection was completed in merely over 100 days, demonstrating the company’s solid engineering capability and efficient project execution.
As the nation’s largest project of its kind and the first large-scale BTM energy storage project in the aluminum sector, this energy storage power station is expected to reduce the power cost of aluminum production in the Guangyuan Economic Development Zone Aluminum Industrial Park by approximately RMB 140 per ton. It will save over RMB 60 million in annual power costs, cut standard coal consumption by around 19,700 tons per year, and reduce carbon dioxide emissions by about 52,000 tons, markedly boosting corporate economic benefits and accelerating green transformation.
The official operation of the project consolidates the foundation for low-carbon and high-quality development of China’s Green Aluminum Hub. It also marks Great Power's breakthrough in the BTM energy storage business, providing a replicable model for high-energy-consuming industries to cut costs, improve efficiency and pursue low-carbon transformation via smart energy solutions.
Going forward, Great Power will continue to focus on energy storage technological innovation, inject impetus into the green transformation of various industries and the development of the new power system, and contribute steadily to the achievement of the national dual-carbon goals.
