World's first 300-MW compressed gas energy storage power station achieves grid connection and power generation

According to the official website of the State-owned Assets Supervision and Administration Commission, at 9 o 'clock on April 9, the world's first 300 MW pressurized gas energy storage power station - Hubei Yingcheng 300 MW pressurized gas energy storage power station demonstration project was successfully connected to the grid for the first time, creating three world records for single power, energy storage scale, and conversion efficiency, as well as six industry demonstrations, dozens of international first, and the world's first breakthrough.
The project adopts the pressurized gas energy storage system solution independently developed by China NENG Construction, which is a national new energy storage pilot demonstration project and the world's first grid-connected 300MW pressurized gas energy storage power station. The total investment of the project is about 1.95 billion yuan, the single power is 300 megawatts, the energy storage capacity is 1500 megawatt-hours, and the system conversion efficiency is about 70%.
Compressed air energy storage technology is one of the most mature physical energy storage technologies in addition to pumped storage, and it is also a hot spot in the research and development of large-scale long-term energy storage technology. The construction cycle of 300MW pressurized gas storage power station in Yingcheng, Hubei Province is about 2 years, far lower than the 6-8 years of pumped storage, which is equivalent to pumped storage in scale, life, cost and efficiency, and can be called "super green charging bank", which is the key technology for the construction of a new energy system and the development of a new power system in China and an important direction for cultivating strategic emerging industries.
The successful grid-connection of the project verifies the reliability, innovation and extensibility of the large-capacity, high-efficiency and ultra-long-term "compressed gas energy storage system solution", provides a demonstration for the commercial application of large-scale new energy storage technology, and marks that China's high-power compressed gas energy storage technology has reached the world's leading level.

It is understood that after the completion of the project, it can effectively improve the peak load capacity of the regional power grid, while promoting the grid to absorb more wind power, photovoltaic and other new energy. The project can store energy for 8 hours and release energy for 5 hours per day, with annual gas storage of 1.9 billion standard cubic meters and power generation of about 500 million KWH, which will provide an important driving force for industrial upgrading and economic development in the central region, according to the official website of the State-owned Assets Supervision and Administration Commission, at 9 o 'clock on April 9, 2016.
