In the current era of deepening energy security and sustainable development concepts, energy storage, as a key transformative force in the energy sector, is ushering in a golden period of rapid development. Lisiner Energy continues to deepen its comprehensive layout and innovative exploration of energy storage applications, with diversified projects blooming in multiple locations across the country.

As the largest industrial and commercial energy storage project in Hunan Province, the stable operation of the first phase (20.7MW/120MWh) of Lisiner Chenzhou Nonferrous Metal Smelting 28MW/160MWh Industrial and Commercial Energy Storage Project has provided a new benchmark for the sustainable transformation of local high energy consuming enterprises.

Project Overview

The project covers an area of 8.5 acres, with a grid connected voltage of 10kV and a total investment of 140 million yuan. It is expected to transfer a peak electricity load of 50 million kilowatt hours per year. On the basis of ensuring the stability of enterprise electricity consumption, it can also support the core production line to work at full load for 5 hours under power restrictions.

Since its integration into the grid, the energy storage power station has completed 100% daily electricity consumption according to the planned curve. According to calculations, power stations can effectively reduce the electricity costs of enterprises by about 30 million yuan per year, and the estimated economic benefits throughout the entire lifecycle can reach 600 million yuan. In the future, VPP virtual power plant access will be supported to further enhance the revenue model, and the overall economic benefits of the project will be significant.

Lisiner deeply considers customer needs and creates solutions with "applicability+architecture, AI+control, and 5-dimensional+system" as the core, helping enterprises move forward rapidly on the path of sustainable development.

Applicable+ System Architecture

Equipped with 6 * 3.5MW/20MWh subsystems, each subsystem includes 1 booster tank and 4 * 5MWh containerized energy storage system

Implement modular deployment using a string based architecture, adopting a "two clusters, one management" topology structure without the "barrel effect"

The system lifespan increases by 30%, and the capacity loss caused by faults during maintenance decreases by 90%

AI+Smart Platform

Equipped with Lisiner one-stop digital intelligence platform, realizing AI empowered full chain collaborative management

By combining real-time data such as battery status, seasonal climate, environmental changes, and load fluctuations, the solution achieves a comprehensive energy efficiency range of 87% -89% on the 10kV side

Effectively support the optimization of users' electricity costs, support the appreciation of energy storage assets, and expand broader business models

5+security guarantees

Configure Class A lithium iron phosphate battery cells and establish a "3+2" safety protection system

Implement the "one pre release, two release, and three elimination" measures for fire safety

Equipped with an intelligent BMS system, creating a "comprehensive - no dead corners" security guarantee from battery cells to the entire machine

Project Value

At the current stage of the project, auxiliary power grid peak shaving and frequency regulation can effectively enhance the regional power grid's ability to meet peak loads in summer and winter. As the largest industrial and commercial energy storage project in Hunan Province, this power station has important demonstration significance and provides strong support for improving the flexibility and stability of the local power grid.

In the future, based on the reserved interface for integrated construction of photovoltaic and energy storage, it will be convenient to access clean energy and help enterprises efficiently build green smart microgrids, fully reflecting the multidimensionality and comprehensiveness of the project.

Lisiner will actively explore the innovative model of "energy storage+" based on the development strategy of "leading from points to areas and expanding from areas to bodies", create a new energy industry ecosystem, and contribute to energy transformation and sustainable economic and social development with a more determined pace.
