State Grid Corporation of China completed more than 450 billion yuan in fixed-asset investment from January to September, up 5.2% year on year. Over the first three quarters, the company advanced project construction in a coordinated way, made every effort to ensure power supply during the summer peak, continued to optimize power supply services, and deepened reform and innovation.
Summer Peak Power Supply
State Grid deployed 24 key work items for summer supply in advance and handled challenges including two new record highs in system load, a peak load of 1.27 billion kW, and load staying above 1.2 billion kW for 26 consecutive days, keeping power supply stable and orderly. Facing natural disasters such as a mudslide in Gyirong, Tibet, typhoons “Bavi” and “Dolphin”, and severe floods in Shenyang, Liaoning and Dunhua, Jilin, State Grid operated the whole grid as one coordinated system, deploying emergency forces and supplies in advance to carry out emergency repair and disaster relief.
UHV and New Grid Construction
Since the beginning of this year, UHV projects such as Shaanbei-Anhui and Yanwei have been commissioned one after another, while key projects including Datong-Tianjin South, Gansu-Zhejiang, the Chongqing-Guizhou, Fujian-Jiangxi and Hunan-Guangdong DC projects and the Hubei-Anhui back-to-back DC project are proceeding in an orderly manner. To date, State Grid has built 44 UHV projects (“23 AC and 21 DC”) with inter-regional and inter-provincial transmission capacity exceeding 380 million kW. State Grid has also released measures to support the achievement of the national carbon peaking goal during the 15th Five-Year Plan period, improved grid-connection services for new energy, and supported new business formats such as large bases in desert, Gobi and wasteland areas, distributed PV grid connection, green power direct connection, and source-grid-load-storage integration.
Power Supply Services and Market Building
State Grid released 10 measures, including upgrading the “three zeros” convenient power connection service and supporting highly reliable electricity use for new quality productive forces. Electricity spot markets in Anhui, Shaanxi and Fujian have entered formal operation, and the inter-provincial electricity market and the medium- and long-term markets in 21 provinces now operate continuously on every calendar day. State Grid innovated an inter-provincial transmission rights mechanism and achieved two-way trading with China Southern Power Grid. In terms of technological innovation, State Grid built the nation’s first grid-friendly high-power electric heavy-duty truck charging demonstration station, developed the full set of key equipment for the world’s largest-capacity grid-forming static var generator (SVG), and had 37 pieces of equipment selected into the sixth batch of first (set) major technical equipment in the energy sector issued by the National Energy Administration.
