State Grid Corporation of China to Invest $75.8 Billion for Ultra-High-Voltage Transmission Projects in Next Five Years

---

Researched by Industrial Info Resources (Sugar Land, Texas)--State Grid Corporation of China (Beijing) will invest $75.8 billion for ultra-high-voltage transmission projects with a total length of 40,000 kilometers in the next five years, according to Zhenya Liu, the general manager of State Grid Corporation of China.

By 2015, a strong nationwide grid, comprised of "three latitudinal and three longitudinal" ultra-high-voltage AC transmission projects and 11 ultra-high-voltage DC transmission projects, will be established in China.

Because of a recurring shortage of coal transportation capacity in China, it is necessary to attach equal importance to both coal transmission and power transmission, said Liu Zhenya at the groundbreaking ceremony for the expansion of the first ultra-high-voltage transmission line in both China and the world.

In the next 10 years, China's ultra-high-voltage grid should grow significantly. Power consumption and the installed capacity of power equipment in China is expected to reach 6.1 trillion kilowatt-hours (kWh) and 1,440 gigawatts (GW), respectively, by the end of 2015. By the end of 2020, these values will rise to 7.8 trillion kWh and 1,760 GW.

Following the construction of large-scale coal-fired, nuclear and renewable energy-based power plants, it's expected that the inter-regional (provincial) power transmission will reach more than 400 GW by 2020. Therefore, accelerating the construction of the ultra-high-voltage grid is urgent, said Liu.

By 2015, the wind power and coal power generated in Inner Mongolia, Shaanxi and Hebei will be transmitted to northern, central and eastern China via the three longitudinal transmission passages. The northern coal-fired power and southwest China's hydropower will be transmitted to northern China, central China and the Changjiang River Delta via the three latitudinal ultra-high-voltage transmission passages.
