Each FPV systemgenerates about 120 000kWh of electricity annually which will be used to power nearby pumping station or air compressor house of the reservoir. Following the establishment of Hong Kong’s first hydropower plant at Tuen Mun Water Treatment Works, we completed the construction of a second hydropower plant at Sha Tin Water Treatment Works, and its operations began in the third quarter of 2020. The design for the hydropower plant at Ma On Shan Water Treatment Works was completed which will be commissioned in 2024. 繼香港首個水力發電站在屯門濾水廠落成 後，位於沙田濾水廠的第二個水力發電站 亦已竣工，並於二零二零年第三季開始投 入使用。而位於馬鞍山濾水廠的水力發電 站的設計工作亦已完成，預計於二零二四 年投入運作。 水力發電廠 Hydropower Generation Plants 沙田濾水廠的水力發電站 Hydropower Plant at Sha Tin Water Treatment Works WSD Annual Report 2020/21 57 Operational Sustainability 可 持 續 運 作
