ChiChi Nanan and ShiZhun, Taiwan

Pushing renewable energy

Following orders for two hydropower plants in 2019, EPC-contractor Nan Dao Engineering has awarded a contract for a further 13 small turbines at seven different locations in Taiwan to ANDRITZ Hydro. As with the earlier projects, ­Chichi Nanan 2 and Hoshan, the hydropower stations will be added to an existing dam and irrigation canal and will thus help to boost renewable energy in Taiwan.

Six of the seven new power stations will be equipped with a total of 12 bevel gear Bulb turbines with runner diameters of 1,770 mm and 2,150 mm. One of the projects, the Shizhun power station, will be equipped with one vertical Compact Francis turbine with a runner diameter of 1,245 mm. The Bulb turbine sites are located mainly in central Taiwan while the Francis turbine is near the capital Taipei.

The delivery of the first main turbine components is scheduled for the third quarter of 2021.

Taiwan has become a very interesting market for hydro and especially small hydro over recent years as the government has set ambitious targets to increase the share of renewable energy.

The trust the customers place in ANDRITZ Hydro is proven with these follow-up contracts. ANDRITZ Hydro is proud to be a part of the positive development of renewable energy in Taiwan.

Sustainable energy out of urban infrastructure

Existing irrigation canals and drinking water reservoirs in urban areas can be effectively used for the generation of electricity. Using small hydropower plants developed by ANDRITZ Hydro, this water may be harnessed to generate electrical energy. The units can be applied in any number of diverse locations. The only requirement is an economically viable combination of head and flow. By using this electrical energy local communities can be supplied with power and thousands of tonnes of CO2 emissions can be saved over time.
