LHD 1.7MW turbines

Supported by the SFPMRE, the Hangzhou United Energy Co. Ltd. is developing the LHD Tidal current energy demonstration project. The #1 demonstration platform was deployed near Xiushan Island in March 2016. They plan to install 7 turbines in their platform, with installed capacity of 3 400 kW. 2 turbines (600 kW, 400 kW) were installed on the platform in July and connected to the grid in August 2016. The amount of electricity accumulated was more than 1GWh until December2018. In 2016, Hangzhou United Energy Co. Ltd. was funded RMB 45 million by the SFPMRE to develop new 300 kW h-axis turbines and a new 400 kW v-axis turbines. The turbines were deployed in December 2018; the capacity of LHD project reached 1.7 MW.
