Recently, Narada Power successfully signed an independent energy storage project order with a total capacity of up to 2.8GWh, with the project fully utilizing Narada’s independently developed 314Ah semi-solid energy storage batteries. This is the largest semi-solid battery energy storage project worldwide to date, marking a critical breakthrough in the commercial application of solid-state energy storage battery technology.
Three Major Projects Launched in the Greater Bay Area, Independent Energy Storage Supports Grid Resilience
The won order consists of three independent energy storage projects, with a total capacity of 2.8GWh. Among them, the Shenzhen project scale is 1.2GWh; the Shanwei City arranges two projects, each with a capacity of 800MWh.
After completion, the projects are expected to consume more than 1 billion kilowatt-hours of new energy annually, significantly enhancing the regional grid’s capacity to accommodate renewable energy, effectively alleviating the power supply and demand contradictions in the Guangdong-Hong Kong-Macao Greater Bay Area, while reducing carbon dioxide emissions by about 1 million tons annually.
This project represents a major breakthrough in the company’s “energy storage technology + scenarios” approach. Shenzhen, as a megacity, requires extremely high safety and cycle life standards for energy storage systems; Shanwei relies on offshore wind power resources and requires energy storage to support grid stability. Narada’s semi-solid battery energy storage system precisely meets the core needs of these two application scenarios.
Semi-Solid Battery Solves Safety and Cost Challenges
The technical core supporting this mega energy storage project is Narada Power’s independently developed 314Ah semi-solid energy storage battery. This battery achieves a major leap in safety and performance through two key innovations: “oxide solid-liquid hybrid technology” and “high melting point polymer separator.”
Narada Power’s technical team has overcome key material and process technology challenges including solid-state electrolytes and interface wetting agents.
The 314Ah semi-solid energy storage battery innovatively applies an oxide-based solid-liquid hybrid electrolyte, significantly suppressing internal lithium dendrite growth, reducing thermal runaway risk, while also maintaining ionic conductivity, providing dual guarantees for long battery life and high safety.
Acceleration of Solid-State Battery Commercialization
This is the first time solid-state battery technology has achieved commercial application in a gigawatt-hour-level energy storage project globally.
The signing of this order reflects the industry’s high recognition of Narada’s solid-state technology and engineering capabilities, and also provides operational data support for the company’s subsequent expansion into data center energy storage, C&I energy storage, and other scenarios.
Solid-state battery technology can meet the core demands of “ultra-high safety” and “long-term reliability” for large-scale energy storage. For the entire industry, large-scale commercialization will strongly drive the maturation and cost reduction of the solid-state battery supply chain, injecting powerful momentum into industry technological upgrades.
Narada Power has always followed the technology development strategy of “develop one generation, reserve one generation,” continuously conducting forward-looking research. The company began solid-state battery development in 2017 and is one of the earliest enterprises in China to layout solid-state batteries.
By the end of 2024, the Zhejiang Province key R&D program project undertaken by Narada Power passed acceptance evaluation, successfully developing a 30Ah all-solid-state battery that solved the “solid-solid interface” problem, effectively improving the cycle life and rate performance of all-solid-state batteries.
In April 2025, Narada Power released the 783Ah ultra-high capacity energy storage solid-state battery. Through three core technological breakthroughs—“flexible two-phase oxide solid electrolyte,” “multi-layer heterogeneous composite structure design,” and “in-situ electrolyte film formation”—the battery’s energy density and safety performance achieved a leap forward.
