Recently, the 500 kV transmission project of the Chifeng 1 GW Desert Wind-Solar-Storage Base, built with the participation of CEEC North China Electric Power Engineering Institute, was commissioned.

Rooted in the new energy strategic layout of eastern Inner Mongolia, the Chifeng 1 GW Desert Wind-Solar-Storage Base project is a controlling, critical, and supporting backbone project for optimizing the regional power grid structure, breaking the bottleneck in green electricity consumption, and consolidating energy supply capacity. North China Institute is responsible for the EPC contract of the project’s 200 kV/500 kV collection station and the supporting 150 MW/300 MWh ESS.

The commissioning of this project has opened a key corridor for delivering GW-level green electricity from Chifeng, enabling the transmission of approximately 2 billion kWh of clean electricity annually. It will effectively enhance the regional power grid’s dispatch capacity and resource complementarity.
