This year, several provinces have adjusted their electricity pricing policies, introducing new uncertainties for the domestic commercial and industrial (C&I) energy storage market. Narada is delivering the key to overcoming these challenges with its integrated hardware + software + operations & maintenance (O&M) energy storage solution, enabling greener energy use for C&I customers.
In Wenzhou, the production base of Hongfeng Copper Foil once faced serious power-use challenges—spiking peak-hour electricity prices increased production costs, and intermittent power restrictions threatened production stability.
Today, with the stable operation of a 5 MW/10 MWh energy storage station on the factory grounds, this Narada-developed system is quietly solving those problems, even under a high-intensity "two charges, two discharges" daily operation pattern.
Amid the major shifts in the C&I energy storage landscape, the question remains: how to ride out the cycles and create stable value for customers? As one of the earliest companies to enter the C&I energy storage field, Narada has accumulated extensive experience in user-side power station construction.
Located on the Wenzhou coast, the project site's high salt-mist and high-humidity climate places stringent demands on the environmental adaptability and reliability of the energy storage system, while also driving up system energy consumption and O&M costs.
The project's liquid-cooled energy storage system, developed by Narada, offers both compressor cooling and natural cooling modes, switching intelligently based on ambient temperature and operating conditions. This reduces auxiliary power consumption by 30%. The self-adjusting intelligent temperature control system keeps the system-level temperature difference within 3 °C, effectively extending service life and ensuring full-lifecycle project returns.
Notably, operational data show that Narada's independently developed and manufactured new-generation BMS delivers excellent active balancing performance, significantly improving system consistency.
Narada's BMS, meeting the AEC-Q100 automotive-grade reliability standard, achieves outstanding precision: single-cell voltage measurement error within ±1.5 mV, high-voltage current acquisition accuracy under ±0.3%—far exceeding the industry average. This ensures the reliability of full-lifecycle data collection for the energy storage system and provides a solid foundation for high-precision SOC estimation.
In the era of digital intelligence, smart O&M has become a critical tool for reducing costs and increasing efficiency. Narada's self-developed intelligent cloud platform, acting like a 24/7 online energy steward, offers real-time operational data monitoring, full data downloads, remote OTA upgrades, and edge-cloud collaborative control. It also features an electricity price strategy optimizer that helps customers refine charge/discharge strategies, maximizing peak-valley arbitrage returns and shortening investment payback periods.
Through this platform, O&M teams can quickly pinpoint anomalies, reducing maintenance costs. Full operational data offline analysis provides the basis for optimizing BMS control strategies and algorithms, as well as for deeply integrating and adapting BMS to specific energy storage scenarios.
In addition, Narada is building a cloud-based AI algorithm, big data analytics, and a digital twin + shadow analysis model. Through a multi-level, multi-dimensional "edge-device-cloud" consistency evaluation engine, both system and cell safety will gain multiple layers of intelligent protection.
As the sea breeze sweeps through Hongfeng Copper Foil's Wenzhou production base, this operating energy storage station is redefining industrial energy management. It is no longer just a container for electricity, but an intelligent hub that balances costs and safeguards production.
Through its self-developed energy storage BMS and intelligent cloud platform, Narada has opened a value gateway for user-side energy storage, providing industries across the board with a reliable pathway toward green, low-carbon transformation—turning energy challenges into competitive advantages through technology.
