BEIJING, Aug. 19 (Xinhua) -- As of 3:00 am on August 15, the Hami-Chongqing ±800 kilovolt ultra-high voltage direct current (UHV DC) power transmission project has transmitted over 5 billion kilowatt hours (kWh) of electricity cumulatively since its commissioning on June 10, injecting strong momentum into Chongqing's energy supply and green development.

Since the beginning of summer, Chongqing's electricity consumption has continued to rise, and the power grid load has reached four historical highs, breaking through the 30 million kilowatt mark for the first time, and reaching a maximum of 30.28 million kilowatts, an increase of 1.91 million kilowatts from last year's highest load, with a growth rate of 6.7 percent.
To ensure the electricity supply for people's livelihood and industrial development in Chongqing, the Hami-Chongqing UHV DC power transmission project has maintained high power operation since its commissioning.

At the Barkol converter station, relevant personnel of State Grid Xinjiang branch use the "artificial+intelligent monitoring" method to carry out operation and maintenance operations. Based on real-time monitoring of the digital system, daily inspections are carried out to establish a sound monitoring, warning, and emergency response mechanism, ensuring the smooth transmission of power from Xinjiang to Chongqing.
While at Chongqing's Yubei converter station located over 2,000 kilometers away, employees of State Grid Chongqing branch utilize a smart inspection system to achieve daily special inspections and real-time monitoring of key equipment. Through intelligent recognition, warning linkage, remote decision-making, and other means, the quality and efficiency of operation and maintenance are improved.
The Hami-Chongqing UHV DC power transmission project has further enhanced Xinjiang's industrial chain advantages in wind power equipment manufacturing, photovoltaic module production, etc.
It will also help Chongqing accelerate the construction of a diversified power mutual-aid system of hydropower, thermal power, wind power and photovoltaic power, providing a continuous stream of "green momentum" for the construction of the Chengdu-Chongqing economic circle and the high-quality development of Chongqing's economy and society.
