Following the contract, Alstom will provide three 200 MW units - pump turbine, motor generator with other key equipment - to the 600 MW new plant. The first unit is due to enter commercial operation on December 2017.
Invested by China Southern Power Grid (CSG), Hainan Qiongzhong pumped storage power station is an important supporting facility for the Hainan Changjiang nuclear station in terms of peak load regulation. Alstom’s largest hydro power manufacturing site in Tianjin, China, will provide a comprehensive range of pumped storage electromechanical equipment including Alstom’s pump turbine, motor generator and balance-of-plant, as well as handling the design, delivery and installation supervision of the project.
During off-peak hours, pumped storage uses the energy from other power stations to transfer water to a high storage reservoir. The stored water will later be reused to generate electricity to cover temporary peaks. As another successful cooperation with CSG, Alstom’s leading pumped storage technology will enable Hainan Qiongzhong pumped storage power station to respond quickly to fluctuating power demand and to manage demand peaks.
“This contract demonstrates our customers’ confidence and trust for the quality and excellent execution capability of Alstom team, and further reinforces our leading position on the hydro pumped storage power market. I strongly believe that our global expertise and complete local value chain will best position us to tap the booming Chinese’s pumped storage power market,” said Fabio Nossaes, General Manager of Alstom Hydro China .
Pumped storage is the most widespread energy storage system in use on power networks, and today there is over 127 GW of pumped storage in operation around the world. Alstom has been providing units - pump turbines and generators - for over 50 years and has supplied 140 units to date, which represents a market share of more than 39 per cent and positions Alstom as the leader in this field.
