With the accelerated pace of urban construction and the rapid development of the new energy industry in Shenzhen, industrial buildings and commercial parks are placing higher demands on the safety of energy storage systems. The "General Design Code for Industrial Buildings" (SIG163-2024) issued by the Shenzhen Municipal Housing and Construction Bureau clearly stipulates that industrial parks should be equipped with intrinsically safe electrochemical energy storage systems. Batteries must ensure that even when exposed to high temperatures or strong impacts during charging and discharging, they will not burn or explode. Furthermore, batteries should not pose a risk of combustion or explosion during use (or charging and discharging).
Against this backdrop, the Shenzhen New Yinzhou Plaza solid-state lead-acid battery energy storage project, invested by Shenzhen Power Supply New Energy Co., Ltd., a subsidiary of Shenzhen Power Supply Bureau, and constructed by Ritar International Group, has been successfully completed and put into operation. Located in the core business district of Luohu, Shenzhen, this project is a landmark demonstration project in Shenzhen's indoor energy storage field. It not only ensures stable power supply to the commercial complex but also showcases an innovative energy storage model of "intrinsically safe + intelligent management," providing a replicable safety solution for the development of smart energy in the city. The completion of the project has been highly recognized by the relevant government authorities, and its successful practice has set an authoritative model and feasible path for the large-scale construction and development of indoor energy storage in Shenzhen in the future.
A Model of Safe Energy Storage in a Core Urban Landmark: 0.375MW/1.5MWh The New Ginza Plaza, located at 3045 Chunfeng Road, Luohu District, Shenzhen, is situated in the heart of the Luohu Port business district. This mixed-use building, integrating commerce, offices, residences, and restaurants, is characterized by high foot traffic and high electricity demand.
The project has a construction scale of 0.375MW/1.5MWh, with an annual discharge capacity of 417.6MWh, saving over 5.81 million RMB over its entire lifecycle.
To cope with peak electricity prices, ensure the safety of users' lives and property, and consider the limited indoor space, this project adopts Ritar solid-state lead-acid battery technology to create an intrinsically safe energy storage system that is "fireproof and explosion-proof."
Upon completion, the project will not only help the park smooth out peak and valley loads and improve power quality, but will also become an important and exemplary project for "indoor safe energy storage" in Shenzhen.
Empowering Urban Green Energy with "Intrinsic Safety" [Solid-State Lead-Acid Battery Core Technology]
The New Ginza project utilizes Ritar's core technology OPzV solid-state lead-acid battery energy storage system, coupled with a self-developed EMS/BMS, achieving full-dimensional management from the cell level to the system level.

04 Intelligent Energy Management System (EMS)
The system is equipped with an AI intelligent energy management system, featuring load forecasting, peak-valley arbitrage, remote monitoring, and unattended operation. All operational data is visualized, achieving true automation and sustainable management.
Customer Value: Fully automated power plant operation, transforming the energy system from "safe" to "intelligent," achieving a visible, manageable, and optimizable energy storage management experience.
Expanding Application Scenarios, Unlocking More Possibilities: Ritar Solid-State Lead-Acid Battery Energy Storage Solution
Ritar's solid-state lead-acid battery energy storage solution not only demonstrated outstanding safety and stability in the New Ginza project but also possesses strong adaptability to various scenarios, becoming a better choice for energy transformation across industries.
Industrial Parks
With its inherently safe "non-flammable and non-explosive" characteristics, it can be flexibly deployed in indoor or underground spaces within factories, easily achieving "industrial upstairs" solutions. While ensuring safety, it reduces electricity costs through peak shaving and valley filling, helping enterprises reduce costs and increase efficiency.
Class A, B, and C Production Sites: Chemical plants, gas stations, timber processing plants, etc.
These types of sites have high fire risks. The solid-state lead-acid battery energy storage system, being non-flammable and non-explosive, can provide safe and stable power support for these sites.
Data Centers and Medical Institutions
In critical load locations, it can serve as a stable backup power source to provide uninterrupted power to core equipment, ensuring the safety of life and data.
Charging Stations and Integrated Photovoltaic-Storage-Charging Systems
The energy storage system has virtual expansion capabilities, effectively mitigating the impact of high-power charging on the power grid and, combined with photovoltaics, enabling the local consumption of clean energy.
Applications in Remote Areas and Outlying Islands
The system operates stably with low maintenance costs, requires no on-site personnel, and can provide highly reliable power support to areas with weak power grids for extended periods.
Dual Benefits, Win-Win Development
This solution not only helps achieve "dual carbon" goals, promotes the consumption of new energy sources and improves grid flexibility, but also brings continuous cash returns to investors, creating a win-win situation for both social and economic benefits.
The launch of the New Ginza project is another important practice of Ritar International Group under the concept of "intrinsically safe energy storage." As a model project jointly built by Shenzhen Power Supply New Energy and Ritar International Group, it not only provides reliable energy security for commercial buildings in Shenzhen, but also provides a reference model for safe indoor energy storage in cities across the country with its safe, efficient, and intelligent technology system.
Ritar will continue to be driven by technological innovation, bringing safe energy storage to more buildings and empowering a green future for cities.
