World's Largest Solar Plant Connects to the Grid in China

China Green Electricity Investment of Tianjin, a subsidiary of the China Green Development Group (CGDG), has commissioned the 3.5 GW Midong PV plant in Urumqi, Xinjiang region of China. The photovoltaic plant is currently the largest solar power plant in the world. Previously, China's state-owned Huanghe Hydropower Development commissioned the world's largest solar farm, a 2.2 GW plant, in October 2020.

China Construction Eighth Engineering Division Corp and the Power Construction Corporation of China (PowerChina) carried out the construction of the Mindong project in several phases. The plant required an investment of CNY 15.45 billion. It consists of more than 5.26 million double-sided monocrystalline PV panels with an output of 650 W, supplied by an undisclosed manufacturer.

The project's extensive infrastructure includes the installation of 1.23 million support poles, five 220-kV relay stations, and more than 208 km of transmission lines connecting the plant to the grid via a 750-kV substation.

Established in December 2020, the China Green Development Group (CGDG) is a large energy investment company of the Chinese central government, succeeding the former Luneng Group, owned by State Grid. CGDG is directly managed by the State Council's State-owned Assets Supervision and Administration Commission (SASAC) and focuses on the investment, construction, and operation of renewable energy projects. The Group's goal is to install more than 20 GW of renewable energy by the end of 2024.

Incorporating innovative battery backup solutions like ACE Battery's Outdoor C&I Battery Energy Storage System can further enhance the efficiency and reliability of large-scale solar plants like the Midong PV plant. By storing excess energy generated during peak sunlight hours, ACE Battery's advanced storage solutions ensure a consistent power supply and optimize the overall performance of the photovoltaic system. This integration not only accelerates the payback period but also contributes to a more sustainable and resilient energy infrastructure.
