LZY Energy Delivers China Lianyungang 94MW/188MWh Energy Storage Project

Lianyungang City, Jiangsu Province, China — A major milestone in utility-scale renewable energy deployment has been achieved with the successful grid connection of the first phase of the Lianyungang 94MW/188MWh Advanced Energy Storage Project on 19 November 2024. The project supports China’s largest single-site “fish–solar complementary” photovoltaic power generation base, with a total installed capacity of 940MW.

The project represents a new generation of photovoltaic-plus-storage integration designed to improve renewable energy absorption, enhance grid stability, and support flexible dispatch. It is based on advanced lithium iron phosphate (LFP) battery technology and high-density containerized energy storage architecture.

LZY Energy provided the integrated energy storage solution and key equipment for the project, enabling rapid delivery and large-scale system deployment.

Project Overview

The project is located in Lianyungang City, Jiangsu Province, within a large-scale “fish–solar complementary” photovoltaic base combining aquaculture and solar generation. This design maximizes land utilization while producing clean electricity at scale.

To address photovoltaic intermittency and grid stability challenges, a 94MW/188MWh energy storage system has been deployed as supporting infrastructure.

Key highlights:

• PV installed capacity: 940MW
• Energy storage capacity: 94MW / 188MWh (design), 209MWh (delivered)
• Grid connection: 19 November 2024
• Functions: peak shaving, frequency regulation, renewable integration, grid support

Application Scenarios

The energy storage system provides multiple grid services:

• Peak shaving and load balancing
• Frequency regulation
• Renewable energy smoothing
• Power dispatch optimization

It plays a key role in increasing the grid’s ability to absorb large-scale solar power.

System Configuration

The project adopts a modular containerized design with a total delivered capacity of 209MWh:

• 36 × 5MWh 20-foot liquid-cooled containers
• 7 × 4.18MWh 20-foot liquid-cooled containers

This configuration enables scalable deployment, efficient transport, and fast installation.

Core Equipment

The system uses advanced 20-foot liquid-cooled energy storage containers with high energy density and long lifecycle performance.

Key specifications:

• Single container capacity: up to 5.015MWh
• Battery architecture: 104 LFP-3141P cells per pack
• System voltage: 1331.2V
• Size: 6580 × 2438 × 2896 mm
• Weight: ~48 tons
• Protection: IP54 (container), IP67 (battery pack)
• Corrosion resistance: C5 coastal rating
