Inner Mongolia’s Arishan 500-kV transmission and transformation project entered operation on October 25, connecting four main transformers to the grid.

The project entered operation at 12:40 p.m. on October 25, according to a Telegram report citing Inner Mongolia Daily. Four main transformers were formally connected to the grid. The reported 500 kilovolts is the project’s voltage level, not its generation output or power-transfer capacity.

The installation is located in the Ulan Buh Desert within Alxa High-Tech Zone, Alxa League, Inner Mongolia. It is identified as the core hub of the “Alxa Power into Wuhai” project. The source describes that broader initiative as Inner Mongolia’s first cross-league/city cooperative project for renewable-energy grid connection and consumption.

The reported milestone is actual commissioning rather than a construction proposal. However, the message does not provide transformer ratings, line lengths, transfer capacity, or connected renewable-generation capacity. It also does not identify a data-center customer or a dedicated AI-compute supply arrangement.
