As the world's first tidal current power station, the LHD Zhoushan Tidal Current Power Station in East China's Zhejiang province, has generated over 8.7 million kilowatt-hour of electricity after eight years of continuous operation, holding the world record for both single-unit capacity and operational duration.

Through iterations of its generator unit, the cost of tidal current power generation per kWh has decreased from 106 yuan ($14.77) with the first-generation unit to 1.1 yuan with the current fourth-generation unit (with scaled installation).

Lin Dong, director of LHD, said the power station will continue reducing costs and further contribute to the efficient use of clean energy.
