German pumping tech selected for hydro plant in China

The State Grid Corporation of China orders 1,200MW in pumped storage from Germany’s Voith

China plans to grow its hydroenergy sector

German pump technology totalling 1,200MW is being used to develop a hydro plant in Southeast China. Chinese energy provider, the State Grid Corporation of China, has ordered four German pumped storage units for the Hongping pumped storage plant in Jiangxi province.

German firm Voith will supply four 300MW pumped storage units to China in a deal worth over EUR 70m.

The Hongping pumped storage plant will have its initial development phase completed in 2015. Once the Hongping project is fully developed it is expected to generate 2,400MW of electricity.

Doctor Roland Münch, president and CEO of Voith Hydro, said: “Pumped storage plants are the only proven, economically attractive technology for storing electricity from other renewable sources, such as wind and solar – particularly when the proportion of these sources in the energy mix is becoming more and more significant”.

The pumped storage plant works as both an energy storage system and a hydroelectric power generator. It stockpiles energy during base-load phases, before making this energy available to the grid for peaking supply needs and system regulation.

According to Voith, China already has 24 pumped storage plants with a total installed capacity of approximately 18,700 MW.

Münch said: “Voith technologies make significant contributions in China when it comes to providing a comprehensive and secure supply of power, saving energy and driving sustainable development on the back of renewable energy sources”.
