The Hami-South-Zhengzhou ±800 kV UHV DC transmission project has successfully transmitted 21.464 billion kWh of electricity. This robust delivery capacity is attributed to the ongoing enhancements in Xinjiang’s energy supply system.In the first half of the year, Xinjiang’s power grid saw its total installed capacity rise to 219 million kilowatts, an increase of 38.42% compared to the previous year. The growth in new energy capacity has been particularly significant, with wind power and photovoltaics reaching an installed capacity of 128 million kilowatts, a 68.67% year-on-year increase. This surge underscores Xinjiang’s accelerated transition towards a cleaner and lower-carbon energy structure.
To ensure the reliable transmission of electricity, State Grid Xinjiang Power Co., Ltd. has been actively developing energy storage projects. This initiative involves building a coordinated “power bank” cluster that includes pumped storage and various new energy storage technologies, such as lithium iron phosphate, all-vanadium liquid flow, flywheel, and supercapacitors. In the first half of the year, Xinjiang added 2.53 million kilowatts/8.25 million kilowatt-hours of grid-connected energy storage, ranking second nationally. Lithium batteries constitute 96% of this newly added energy storage technology. Notably, in southern Xinjiang alone, the installed capacity of new energy storage accounts for 49.4% of the total in Xinjiang, with advanced technologies like grid-type energy storage being widely implemented.
These energy storage systems function by absorbing new energy during periods of low demand and releasing it during peak hours. This process effectively mitigates the intermittency of new energy generation, thereby guaranteeing a stable power supply. As of the end of June this year, Xinjiang’s cumulative installed capacity of new energy storage reached 12.07 million kilowatt-hours. The expansion of new energy storage has led to a 4.6 percentage point increase in the utilization rate of new energy within Xinjiang’s power grid.
State Grid Xinjiang Power Co., Ltd.has implemented a series of measures to enhance its capacity to integrate new energy. On the supply side, a structured working mechanism involving “quarterly coordination, monthly arrangement, weekly coordination, daily control, and post-evaluation” has been established to ensure that new energy projects are integrated as efficiently and as early as possible. On the grid side, significant efforts are being made to construct a robust grid infrastructure, accelerating the progress of key backbone power grid projects to create an energy “high-speed road network” for new energy access and transmission. Furthermore, the company provides crucial support for clean energy sources like wind and solar power. Wind turbines have been allocated priority power generation rights for 24.882 billion kWh, and solar generator sets for 18.185 billion kWh, offering stable market expectations for new energy companies.
