China’s Vision of a Global Grid

Chinese exec calls for bold global grid transformation


EDITOR’S NOTE: This is the first of a two-part series, excerpted and edited, from a speech by Zhenya Liu, chairman of the State Grid Corp. of China, delivered recently at IHS CERAWeek in Houston. Next week: “A Grid to Knit Together the World.”  The SGCC provides grid services to 88 percent of China.

After years of construction, the networks of transportation and information have been interconnected worldwide. The energy network will follow the same direction, which turns out to be a Global Energy Interconnection. 

The worldwide grid is an interconnected strong and smart grid with a UHV grid as the backbone, which will serve as a platform for extensive development, deployment and utilization of clean energy globally. In essence, the global grid is ‘UHV Grids + Smart Grids+ Clean Energy’. UHV grids are the key, smart grid is the foundation and clean energy is the principle.

The global grid will create great economic, social and environmental significance.

Wth the contribution of the global grid, if renewable generation grows at an annual growth rate of 12.4 percent over the world, then by 2050 renewable energy shall increase to 80 percent of total consumption, realizing clean energy supplement forever and completely solving the dilemmas caused by fossil fuels.

By 2050, the total CO2 emission will be controlled at about 11.5 billion tons, half of emissions in 1990, holding the temperature rise to within 2 degrees.

The accumulated investment on the global grid will exceed $50 trillion, tremendously boosting the development of new-emerging strategic industries, renewable energy, new materials and electric vehicle.

Moreover, it will bring great benefits through differences of power tariff levels, time and seasons. In the future, with the development of the global grid, electricity trade will witness a rapid growth and play a pivotal role in pulling economic growth. 

The global grid will curb international disputes and narrow regional gaps. Eventually, our world will turn into a peaceful and harmonious global village, a community of common destiny for all mankind with sufficient energy, blue skies and green land.

The construction of global energy interconnection can be divided into three phases, namely domestic interconnection, intra-continental interconnection, and intercontinental interconnection.

From now on to 2020, we need to promote clean energy development, domestic grid interconnection and smart grid construction in various countries. By 2030, large energy bases shall be established and grids shall be interconnected among countries within the continent.

By 2050, we need to accelerate the development of energy bases at the North Pole (wind power) and the Equatorial Regions (solar power), realizing intercontinental interconnections. By then the global energy interconnection will basically come into being.

At present, the prerequisite conditions for building global energy interconnections are satisfied.
