發展可再生能源有助政府實現二零五零年碳中和的目標。我們把 握面積達24 平方公里的水塘塘面的機遇，積極發展大型浮動太 陽能板發電系統，有效地收集太陽能。隨著位於石壁水塘、船灣 淡水湖和大欖涌水塘的先導系統成功安裝後，我們正計劃在這三 個水塘建造更大的浮動太陽能板發電場，預計每年合共可生產 達50千兆瓦時的可再生能源。與此同時，我們亦正探討在船灣 淡水湖興建大型浮動太陽能板發電場的可行性。我們計劃逐步提 升可再生能源產能，目標是在二零三五年開始年產量達160千兆 瓦時。宏觀來看，就算只能運用10%的塘面面積，我們已可以 將年產量進一步提升至約290 千兆瓦時，足以抵消二零二一至 二二年度部門總耗電量的約37%。 The development of renewable energy contributes towards the Government’s target of achieving carbon neutrality by 2050. We grasp the opportunity brought by the 24 square kilometres of reservoir water surface to proactively develop mega-scale floating photovoltaic systems at impounding reservoirs for harnessing solar energy efficiently. With the successful pilots installed at the Shek Pik, Plover Cove and Tai Lam Chung reservoirs, we are planning larger floating solar farms at these three reservoirs to generate about 50 gigawatt-hours per year (GWh/year) of renewable energy in total. In parallel, we are also exploring the feasibility of a mega-scale floating solar farm at the Plover Cove Reservoir. Our plan is to increase progressively the renewable energy generation capacity up to about 160 GWh/year by 2035 onwards. From a macroscopic perspective, even if only 10% of the water surface area is leveraged, we can further increase the generation capacity up to about 290 GWh/year which can offset about 37% of the Department’s total energy consumption in 2021/22. 大欖涌水塘的浮動太陽能板發電系統 Floating PV System at Tai Lam Chung Reservoir 水務署 二零二一至二二年年報 WSD Annual Report 2021/22 8 署長的話 Director’ s Statement
