China begins construction of 4 GW renewable transmission project in Inner Mongolia www.alcircle.com
Construction of a 4-million-kilowatt new energy transmission project began on April 15 in Jungar Banner, located in Ordos, North China’s Inner Mongolia autonomous region, according to State Grid East Inner Mongolia Electric Power Co.
The project is part of the Mengxi–Tianjin South ultra-high voltage (UHV) transmission corridor. It will run from the 500-kV Dalu Substation to the 500-kV Buertao Substation, and further connect to the 1,000-kV Ordos UHV Substation.
The development includes two new 500-kV substations at Dalu and Buertao, along with 279 kilometres of transmission lines and 340 towers. The total investment for the project is RMB 1.94 billion (around USD 283 million).
Once completed, the project will strengthen the transmission of renewable energy from Ordos to the Beijing–Tianjin–Hebei region. It is expected to deliver around 14 billion kilowatt-hours of electricity annually, helping meet rising power demand.
The project is also expected to meet environmental goals by reducing carbon dioxide emissions by approximately 4.4 million tonnes per year.
