  As an important part of the "West-to-East Power Transmission" energy strategy, Yanmenguan Converter Station has always maintained safe and efficient operation, and the power delivered has repeatedly hit new highs, reaching 46.75 billion kilowatt-hours in 2023, a year-on-year increase of 26%.

  Yanmenguan Converter Station continues to transport the abundant thermal power and wind power resources in northern Shanxi to East China, greatly improving the new energy consumption level of Shanxi Power Grid, effectively alleviating the tight power supply and demand situation in East China during peak hours, and playing a key role in promoting the development of Shanxi's energy base and energy export. It is of great significance to transport, expand the scope of new energy consumption, accelerate the energy revolution and transformation, and alleviate the pressure on environmental protection, providing a stable energy supply to achieve the "double carbon" goal.
