The largest electrochemical energy storage project in China has started construction
On December 25th, the new energy supporting energy storage project of Huaneng Longdong Energy Base was fully launched in Qingyang, Gansu Province. This is currently the largest electrochemical energy storage project under construction in China.
As a supporting new energy storage project for the "Gansu Electricity to Shandong" initiative, this project has a total capacity of 600 megawatts / 2,400 megawatt-hours and is constructed at two sites.
The picture shows the groundbreaking ceremony.
Among them, the energy storage power station adopts the single-stage distributed energy storage technology independently developed by Huaneng Clean Energy Research Institute. It is composed of hundreds of battery cells connected in series to form a battery cluster. Each battery cluster performs distributed energy processing through a single low-power PCS, achieving one-cluster-one-management and simple and flexible operation and maintenance. It has advantages in terms of consistency of battery cluster state, system capacity availability, cycle life, and system availability under faults. The average comprehensive efficiency is about 4.6 percentage points higher than that of centralized technology route power stations, and the average available capacity retention rate is increased by about 5 percentage points.
This project is expected to be completed and put into operation in the first half of 2025 in tandem with the Longdong to Shandong UHVDC project. Once completed, it will consume approximately 840 million kilowatt-hours of new energy annually, with a single charge capable of storing about 2.4 million kilowatt-hours of electricity. This will effectively promote the consumption of new energy projects and contribute to the safe and stable operation of the power system. Contribute to the construction of a new energy system that is clean, low-carbon, safe and efficient.
