State Grid UHV Energy Storage Power Station

How many UHV lines does State Grid have?

In January 2009, State Grid energized its first UHV demonstration line —a 650-km, 1,000-kV UHV AC transmission line that linked the North China and Central China regional grids. Ten years on, State Grid has completed 19 of 30 proposed UHV lines.

Why is China building a UHV power grid?

State Grid is also building a world-leading set of ultrahigh-voltage AC lines, to help eastern China’s regional AC grids absorb the output from those massive lines. “The UHV AC power grid is like a deep-water port, and the UHV DC is like a 10,000-ton ship.

Which is the highest-altitude UHV direct current power transmission project in the world?

It is currently the highest-altitude UHV direct current power transmission project in the world. State Grid said the project will pass through four provincial regions: Tibet, Sichuan, Chongqing and Hubei. The Tongshan pumped-storage hydropower station will be equipped with four sets of power generators, each with a capacity of 350,000 kilowatts.

What is ultra-high-voltage electricity transmission (UHV)?

Ultra-high-voltage electricity transmission (UHV electricity transmission) has been used in China since 2009 to transmit both alternating current (AC) and direct current (DC) electricity over long distances separating China's energy resources and consumers.

Should China move more energy through UHV DC?

They argue that the country must move far more energy via UHV DC to maximize the use of renewable energy while slashing reliance on coal. State Grid is also building a world-leading set of ultrahigh-voltage AC lines, to help eastern China’s regional AC grids absorb the output from those massive lines.

What does UHV stand for?
