Micro hydropower system for building applications, usable with solar

Japanese startup Yumes Frontier has developed a 2.7 kW micro-hydropower system that can be used in some buildings. It can also be combined with solar to provide power for lights and surveillance cameras.

World’s largest hybrid hydropower-photovoltaic station

Yalong Hydropower is building a 1 GW solar park that will be connected to an operational 3 GW hydropower facility on the Yalong River in southwestern China.

Hybridizing floating solar with hydropower

Scientists from the National Renewable Energy Laboratory (NREL) have said that the combination of floating solar with hydropower could reduce PV curtailment.

Thai utility EGAT launches tender for hybrid project combining hydro, floating PV and storage

The Ubol Ratana Dam Hydro-Floating Solar Hybrid Project will have a capacity of 24 MW and will be located the company’s Ubol Ratana Dam in Khok Sung, Ubolratana District.

Canadian hydropower dam to be coupled with 180 MW of lithium-ion battery storage

TransAlta has planned to start construction on the storage facility in March 2023 and to complete it within nine months. The 180 MW battery facility is designed to be charged by the existing Ghost Hydroelectric facility when demand is lower.

State Grid of China switches on world’s largest pumped-hydro station

Located in China’s Hebei province, the 3.6GW facility consists of 12 reversible pump generating sets with a capacity of 300MW each and has a power generation capacity from storage of 6.612 billion kWh.

Combining big floating solar with hydropower

Scientists in Bangladesh have evaluated how a 50 MW floating PV plant could be integrated with the 230 MW Karnafuli Hydroelectric Power Station, located at the Kaptai Dam on the Karnaphuli River. They found that the two energy sources can be perfectly optimized and that PV can compensate for the reservoir’s shortage of water storage during the winter season while hydropower can compensate for the poor yields of the floating array during the monsoon season.
