WSD Annual Report 2022/23

Contributing towards Hong Kong's Climate Action Plan 2050 Leveraging the water surface area of reservoirs for renewable energy development not only helps offset the Department’s energy consumption but also contributes towards the Government’s decarbonisation target of achieving carbon neutrality as pledged in the Hong Kong’s Climate Action Plan 2050. The pilot FPV projects at the Shek Pik Reservoir, Plover Cove Reservoir and Tai Lam Chung Reservoir have built a solid foundation for the future development of FPV systems on reservoirs in Hong Kong. Following a feasibility study, we are progressively planning to implement large-scale floating solar farms at impounding reservoirs in Hong Kong. In coming years, the first large-scale floating solar farm in Hong Kong is being planned to be installed at the Plover Cove Reservoir. Scheduled to be commissioned in 2026, the floating solar farm will generate about 6 gigawatt-hour per year (GWh/ year) of electricity, constituting about 0.8% of the WSD’s total energy consumption as at 2022-23, which is equivalent to the annual electricity consumption of around 1 800 households with a reduction of about 4 200 tonnes of CO2 emission. Our long-term plan is to increase the renewable energy generation capacity up to about 60 GWh per year from 2035 onwards. 大欖涌水塘 Tai Lam Chung Reservoir 安裝於石壁水塘(大嶼山)、船灣淡水湖(大埔)和大欖涌水塘(屯門)水面上 的浮動太陽能板發電系統利用水的自然冷卻效果提高太陽能板的發電效率,同 時亦有助政府於二零五零年之前實現碳中和的目標。水務署正計劃擴大浮動太 陽能發電技術的應用規模。 The FPV systems on the water surface at the Shek Pik Reservoir (Lantau), Plover Cove Reservoir (Tai Po) and Tai Lam Chung Reservoir (Tuen Mun) can naturally cool the solar panels to enhance the overall efficiency in electricity generation while contributing to the Government's decarbonisation target of achieving carbon neutrality before 2050. The WSD is planning to deploy the technology on a larger scale for developing floating solar farms at impounding reservoirs. 船灣淡水湖 Plover Cove Reservoir 石壁水塘 Shek Pik Reservoir 為《香港氣候行動藍圖2050》出一分力 利用水塘水面發展可再生能源不但有助抵銷部門的用電量,更 可為政府於《香港氣候行動藍圖2050》中承諾實現碳中和的 目標作出貢獻。而石壁水塘、船灣淡水湖和大欖涌水塘的先導 計劃亦為未來在香港水塘發展浮動太陽能發電系統奠下堅實基 礎。 在完成可行性研究之後,我們計劃在香港水塘逐步發展大型浮 動太陽能板發電場,並計劃於未來數年在船灣淡水湖建造首 個大型浮動太陽能板發電場。該發電場預計將於二零二六年 完工,每年預計可生產約6 000 000 度電,約等於水務署二零 二二至二三年度總用電量的0.8%,相當於1 800 戶普通家庭的 年用電量,亦為地球每年減少4200 公噸的二氧化碳排放量。 長遠而言,我們計劃從二零三五年起,將可再生能源產電量提 升至每年約60 000 000 度。 水務署 二零二二至二三年年報 WSD Annual Report 2022/23 66 Scale up 升 級 開 拓
