Narada Power: Thirty years of focus and innovation in the energy storage industry

In 2024, Narada will usher in its 30th year of development. Over the past 30 years, Narada has witnessed the rapid changes in the energy storage market and experienced its development from small to large and from large to strong. These 30 years have also witnessed the company's focus and deep cultivation in the field of energy storage.

In the context of the "dual carbon" era, the energy storage industry is in a period of accelerated development, and the company's external environment has presented unprecedented major opportunities. In a market that is constantly involuted, maintaining a long-term strategic focus and insisting on focus and innovation are also one of the keys to Narada's ability to cross industry cycles and perform well.

Professionalism due to focus

Since the 1990s, Narada Power has entered the industrial energy storage industry with backup power supply as the starting point. From the analog 2G era to the digital 5G era, as a major supplier to global communication operators, service providers and system integrators, it has been deeply involved in the development of the global communication industry.

Since 2010, the company has been actively engaged in the research and development and application exploration of new energy storage technologies. In 2011, it invested in the construction of the first new energy storage demonstration project in China, the "Dongfushan Island Wind, Solar, Oil and Storage Microgrid Demonstration Project", and has successively undertaken more than 50 new energy storage demonstration projects at home and abroad.

In 2016, Narada took the lead in the industry and began to promote the commercialization of energy storage. It has built many energy storage power stations based on various application scenarios at home and abroad. Among them, the 160MWh smart distribution network energy storage power station project in Singapore Industrial Park built in 2017 is the world's largest single multi-energy complementary energy storage project. Since the project was put into operation, it has become a benchmark for domestic energy storage projects.

Since 2021, the company's new energy storage business has entered a stage of large-scale development. At present, the company's cumulative installed capacity of energy storage business has reached 50GWh, of which the cumulative installed capacity of new power energy storage exceeds 6GWh, distributed in more than 40 countries around the world.

Starting from industrial energy storage to the rapid development of new energy storage business, Narada has always focused on the energy storage track, without distraction, and continued to be committed to innovating product technology and expanding market demand, making focus and improvement the key to success in the company's strategic transformation.

Over the past 30 years, it is precisely because of the company's high focus on the energy storage industry, technology, and products that the company has been able to continuously break through key technical bottlenecks, build an integrated layout of the energy storage industry, and its competitive advantages have gradually emerged.

Professionalism makes energy storage safer

In the past two years, the number of newly registered energy storage companies has increased sharply, but there are both good and bad companies. The energy storage industry is not only closely related to the stable operation of the power system, but also to the safety of life and property. Safety has always been the red line and bottom line of the industry.

The safety of energy storage systems needs to be broken through and achieved from multiple dimensions, including battery safety, management safety, and fire safety.

In terms of the safety of the battery cell itself, Narada's dedicated energy storage battery cell uses a composite solid electrolyte membrane with high ion conductivity and good high-temperature stability, combined with positive and negative electrode coated lithium-conductive electrolyte technology, to avoid the use of flammable organic electrolytes and improve the intrinsic safety of the material.

In addition, Narada Power insists on using the lamination process, so that the battery cell can remain flat when the pole piece expands and contracts during the cycle, the internal stress is evenly distributed, and there is no stress concentration problem at the arc corners, which is safer to use. This establishes the first line of defense for the safety of the battery body.

In terms of management safety, Narada Energy Storage BMS comprehensively monitors the voltage, current, temperature, etc. of the battery. Through the four-layer three-dimensional protection of "data collection layer, charge and discharge control layer, system management layer, and cloud service layer", it can control the health status of the battery in real time. When an abnormal battery status is detected, the BMS will issue an alarm in time, greatly reducing the probability of system failure. This establishes the second line of defense for management safety.

The energy storage system also needs a third active safety line of defense. Narada Energy Storage System implements "one warning, two discharges, three eliminations" in terms of active safety. The system has established a multi-dimensional early warning model based on the combination of data drive and battery cell mechanism model, and a three-level detection and early warning, which can effectively prevent thermal runaway.

The energy storage system is equipped with inhibitors that can directly reach the PACK and act on the battery cells, providing efficient fire prevention and continuous suppression. In addition, the energy storage system will formulate strategies and program control valves based on the thermal runaway model to release inhibitors multiple times to extend the protection time. In terms of passive fire protection, each PACK has a built-in micro-suppression device that is passively triggered to provide backup and dual protection.

Narada is one of the first companies in the world to pass the UL9540 and UL9540A certifications for MW-class container energy storage systems. So far, Narada has passed more than 200 global energy storage standard safety certifications, including the Global Financial Financing Qualification License, which are the world's leading standard safety certifications and fully demonstrate the company's strength.

Professionally promote full-scenario applications

In its 30 years of development, Narada has continuously promoted product innovation and created diversified solutions to meet customer needs and solve industry pain points. Its products have achieved large-scale application in all scenarios.

The technical requirements, product specifications, channels and customer groups on the power supply side, grid side and user side are different. Narada Power develops differentiated vertical products for different application scenarios and ultimately reaches the core needs of customers.

On the power supply side, the Narada energy storage system, in the application of wind, solar (water, fire) and storage integration scenarios, relies on the good consistency of battery cells and the powerful computing power of the battery management system (BMS), cooperates with the wind, solar and storage joint monitoring system status, operates autonomously, tracks scheduling plans, and improves network friendliness.

On the grid side, the Narada energy storage system uses the energy management (EMS) system to realize local intelligent energy management, equipment monitoring, fault alarm and other functions, accept the grid AGC/AVC dispatching instructions, and achieve local full-automatic control and energy management. This solves the problem of low utilization rate of mandatory energy storage and reduced return on investment.

On the user side, the EMS smart energy dispatching system equipped in the Narada industrial and commercial energy storage system can output the economic curve of the operation period and generate the best dispatching strategy by fitting and calculating the electricity price factors, environmental factors and cost factors, so as to better realize peak-valley arbitrage, demand control, reverse power protection and other dispatching methods.

With rich experience in scene application, Narada can carry out integrated design of energy storage system strategy and control based on scene characteristics and customer needs, focusing on different functions such as peak shaving, frequency regulation, and black start, and match the optimal solution.
