At the construction site of the Mengxi Beijing Tianjin Hebei ± 800 kV high-voltage direct current project, the pouring of the iron tower foundation is advancing at full speed. When policy dividends and project progress intersect in the grasslands and deserts, a battle to upgrade the West East power transmission, which is related to the national green power map, has been fully launched.

The amount of electricity transmitted outside reached a new high in the first quarter

In the first three months of 2026, the external transmission capacity of Inner Mongolia's ultra-high voltage power grid reached 46.035 billion kilowatt hours, a year-on-year increase of 6.67%, setting a new high for the same period in previous years. At present, the eastern part of Mongolia has built 8 ultra-high voltage channels with a transmission capacity of 48.7 million kilowatts and a cumulative transmission capacity of over 880 billion kilowatt hours, equivalent to the annual electricity consumption of 290 million households. In the first quarter, the proportion of new energy generation exceeded 42%, and the utilization rate remained above 92%.

Simultaneous construction of supporting facilities at Shage Wilderness Base

The 4 million kilowatt new energy transmission project in the Kubuqi Desert Ordos started construction on April 15th, with 279 kilometers of new 500 kV transmission lines and a total investment of 1.94 billion yuan. After being put into operation, it can transmit 14 billion kilowatt hours of electricity to the Beijing Tianjin Hebei region annually. The Mengxi Beijing Tianjin Hebei ultra-high voltage direct current project is advancing synchronously, and the supporting Dalat Mengxi 1000 kV AC project has been approved. It is planned to start construction in April 2026 with an investment of 4.374 billion yuan. Keywords: New Energy News Network, Resource Conversion

Energy storage scheduling to stabilize wind and solar fluctuations

In early April, many parts of eastern Mongolia experienced heavy snowfall, resulting in significant fluctuations in wind and solar power output. The control center relies on intelligent systems to monitor the power grid flow in real time, scientifically call upon 4.48 million kilowatts of new energy storage resources, and accurately issue frequency regulation instructions. During the 15th Five Year Plan period, Inner Mongolia will build 12 new ultra-high voltage projects, including the "Six Crossings and Six Direct", with a total power transmission capacity of 96.7 million kilowatts. The expected external power transmission capacity over the next five years is expected to exceed 1 trillion kilowatt hours. The infinite scenery of grassland and Gobi is illuminated by the criss crossing steel and silver wires that light up thousands of households.Editor/Gao Xue
