HOME / hainan free trade port to officially launch island wide independent
The creation of a free trade port is the highest level of opening-up in the world today. With rich natural resources and the advantages of being backed by China's mega-market, the Hainan FTP covers the entirety of the 33,900-square-kilometer Hainan Island. The FTP currently has eight open ports and 10 second-line customs ports.
On December 18, the country launched island-wide special customs operations in Hainan, transforming the entire island into a high-standard free trade zone, encompassing not a single port or industrial park, but the whole island.
The island-wide special customs operations in Hainan FTP, that began from Dec 18, are different from how the rest of China's general territory functions. Trade in Hainan operates through a dual-line system: the first line between Hainan and overseas markets, and the second between Hainan and China's mainland.
The FTP currently has eight open ports and 10 second-line customs ports. China aims to build the Hainan FTP into an important gateway that leads the country's opening-up in the new era.

In total, the cost of a 2MW battery storage system can range from approximately $1 million to $1.5 million or more, depending on the factors mentioned above. It is important to note that these are only rough estimates, and the actual cost can vary depending on the specific requirements and characteristics of each project.
On average, the cost of lithium-ion battery cells can range from $0.3 to $0.5 per watt-hour. For a 2MW (2,000 kilowatts) battery storage system, if we assume an average battery cell cost of $0.4 per watt-hour, the cost of the battery alone would be 2,000,000 * $0.4 = $800,000.
A battery cabinet houses and protects the batteries that supply stored energy to a UPS system. It ensures that backup power is readily available whenever primary power is interrupted. Battery cabinets can be installed indoors or outdoors and are designed to provide secure, organized, and scalable energy storage for continuous power delivery.

In 2025, the typical cost of commercial lithium battery energy storage systems, including the battery, battery management system (BMS), inverter (PCS), and installation, ranges from $280 to $580 per kWh. Larger systems (100 kWh or more) can cost between $180 to $300 per kWh. How does battery chemistry affect the cost of energy storage systems?
In 2025, the typical cost of a commercial lithium battery energy storage system, which includes the battery, battery management system (BMS), inverter (PCS), and installation, is in the following range: $280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels.
For large containerized systems (e.g., 100 kWh or more), the cost can drop to $180 - $300 per kWh. A standard 100 kWh system can cost between $25,000 and $50,000, depending on the components and complexity. What are the costs of commercial battery storage?
Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
