Lianyungang Energy Group 150MW/300MWh Independent Shared New Energy Storage Project
Project Highlights
Leading Scale: Jiangsu Province’s first 100MW-class independent shared energy storage project with a total capacity of 150MW/300MWh.
Innovative Model: Adopts the "independent construction + market-oriented sharing" model to provide flexible energy storage services for multiple entities.
Advanced Technology: Equipped with a high-energy-density liquid-cooled battery system, supporting millisecond-level response and multi-scenario coordinated control.
Efficient Grid Connection: Successfully connected to the grid in December 2024, with a daily dispatching utilization rate exceeding 85%.
Core Values
Large-Scale Shared Operation
As a regional shared energy storage platform, it can simultaneously provide leasing, frequency regulation, backup power and other services for new energy power stations, industrial and commercial users, and power grid enterprises, improving asset utilization efficiency and revenue diversity.
Supporting High-Proportion New Energy Consumption
Effectively alleviates the grid transmission pressure during the midday peak of photovoltaic power generation in the regional power grid, increases new energy utilization rate by approximately 6%, and promotes green power consumption by over 200 million kilowatt-hours annually.
System-Level Safety Design
Adopts a three-level protection system of "Pack-level fire protection + cabin-level isolation + station-level monitoring", equipped with combustible gas detection and directional explosion relief devices. The entire system realizes cell-level real-time monitoring and thermal runaway early warning.
Intelligent Operation Platform
Connected to the provincial energy storage dispatching platform and power trading center, supporting remote strategy optimization, intelligent operation and maintenance, and automatic power market quotation, achieving integration of "monitoring, control, maintenance, and operation".
Project Site
Multiple prefabricated energy storage containers are neatly arranged, collaborating with the step-up substation and centralized control center to form a modern energy storage station, reflecting the integrated beauty of industry and technology.
Customer Evaluation
"As an important demonstration of the development of new energy storage in our province, this project not only achieves a breakthrough in scale but also provides replicable and promotable practical experience for the industry in terms of business model and technical level, which is of positive significance for building a new power system."——Relevant Person in Charge of Jiangsu Provincial Energy Authority
Technical Features
Grid-Forming Energy Storage System: Possesses voltage source characteristics, which can enhance local power grid strength and anti-disturbance capability.
Hybrid Battery Configuration: Mainly uses lithium iron phosphate batteries, supplemented by a small amount of sodium-ion batteries for technical verification and operating condition optimization.
Cloud-Edge Collaborative Control: Edge computing terminals realize local rapid control, while the cloud platform completes cross-station collaboration and market decision-making.
Social and Economic Benefits
Provides approximately 120 million kilowatt-hours of peak-shaving electricity for the power grid annually, equivalent to saving 37,000 tons of standard coal.
Improves regional power supply reliability and can serve as a black-start power source to support the recovery of the local power grid under extreme conditions.
The total investment internal rate of return (IRR) of the project reaches an excellent level in the industry, with economically feasible sustainability for promotion.
Application Prospects
The successful commissioning of this project marks a key step for Jiangsu Province in the field of large-scale independent shared energy storage, providing an important reference for load center regions such as the Yangtze River Delta to resolve the contradictions between new energy consumption and power grid peak shaving. In the future, such projects can realize value release through multiple channels including capacity leasing, auxiliary services, and demand response, becoming an indispensable regulatory resource and flexibility guarantee in the new power system.
