根據 Mordor Intelligence 預測,東亞可再生能源市場規模(以裝置容量計算)預計到 2025 年將達到 2.59兆瓦,到 2026 年將達到 2.92兆瓦,到 2031 年將達到 5.51兆瓦,2026 年至 2031 年的複合年成長率為 13.5%。

本報告按技術(太陽能、風能、水力、生質能源能、地熱能和海洋能)、最終用戶(公共產業、商業和工業以及住宅)和地區(中國、日本、韓國、台灣和其他東亞國家)進行細分。市場預測以容量(太瓦,TW)為單位。
如今,區域政策框架已將吉瓦級目標納入經濟規劃。中國的「十五」規劃將省級GDP指標與可再生能源普及率掛鉤,確保發電能力提升的政治課責。日本於2024年制定的第七個能源戰略規劃將2040年可再生能源發電目標提高到50%,並轉向根據批發價格浮動的上網電價補貼(FIT)競標機制。這不僅保障了開發商的現金流,也降低了財務風險。韓國的「RE3020」計畫要求公共機構在2030年實現35%的電力來自可再生能源,為此,截至2025年已舉行了18場大型太陽能發電競標競標。台灣已立法設立一項280億美元的離岸風電和綠色氫能基金,計劃於2030年前完成,能源署將按季度進行監督。當這些計劃結合起來時,區域碳價格的下限將約為每噸 45 美元,這將使未併入聯邦的排放電廠在本世紀末之前失去競爭力。
2024年,亞太地區太陽能和風能的平準化度電成本(LCOE)下降了16%。這主要得益於多晶矽的過剩、N型電池效率超過25%以及雙面組件普及率接近70%,這些因素共同作用,使得組件價格降至每瓦0.09美元。 2024年,中國大規模太陽能發電的平均發電成本為每兆瓦時27美元,比天然氣發電便宜35%。在內蒙古自治區,由於競標了一台6.5兆瓦級、轉子直徑180公尺的風力發電機,2025年風電工程的中標價格為每兆瓦時31美元。離岸風電成本依然高成本,但在全羅南道,一條以本地為導向的供應鏈正在建設中,目標是到2028年將成本降至每兆瓦時55美元,屆時斗山能源的15兆瓦級機艙將實現量產。成本的持續降低正在擴大東亞可再生能源市場的潛在規模,並推動混合儲能系統的應用,以確保在尖峰時段獲得溢價收益。
儘管2025年新增太陽能發電裝置容量180吉瓦,但電網擴容未能跟上,導致2026年1月至2月中國太陽能發電棄光率高達9.2%。在西藏,由於僅有一條3吉瓦輸電線路可供400兆瓦負載使用,白天17%的太陽能發電被浪費。國家電網已撥款6,500億元人民幣用於2027年前新建五條特高壓輸電走廊,但典型建設週期可達四年。在北海道,自從引入高壓直流輸電以來,棄光率有所下降,顯示透過建造有針對性的輸電網路可以解決瓶頸問題。然而,在韓國,如果不安裝儲能設施,可變可再生能源的比例仍僅限於25%。持續的電網擁塞阻礙了短期新增裝置容量,並限制了東亞可再生能源市場的成長潛力。
到2025年,太陽能發電將佔總裝置容量的53.1%。成本的持續下降、沙漠地區大型電站的建設以及強制性的屋頂光伏發電系統鞏固了其主導地位,但正如多晶矽審計所顯示的那樣,其供應鏈正呈現兩極分化的趨勢。 2025年,海洋能的裝置容量將不到300兆瓦,年複合成長率將達到43.4%,而韓國始華大壩和日本普羅透斯渦輪機等項目已具備商業化條件。
風力渦輪機尺寸的不斷增大提升了風電的貢獻。目前,16兆瓦級風力發電平台每年可發電80吉瓦時,比2020年加倍。抽水蓄能電站,例如中國3.6吉瓦的豐寧水力發電廠,能夠穩定波動的電力輸出;而九州地熱發電的加入則豐富了日本的能源結構。隨著太陽能發電成本降至每瓦0.10美元以下,聚光型太陽熱能發電和生質能源仍是小眾市場。離岸風電技術的成功試點計畫預計將東亞可再生能源市場的版圖拓展到傳統資源邊界之外。
According to Mordor Intelligence, the east asia renewable energy market size in terms of installed base is projected to be 2.59 terawatt in 2025, 2.92 terawatt in 2026, and reach 5.51 terawatt by 2031, growing at a CAGR of 13.5% from 2026 to 2031.

This report is Segmented by Technology (Solar Energy, Wind Energy, Hydropower, Bioenergy, Geothermal, Ocean Energy), End-User (Utilities, Commercial and Industrial, Residential), and Geography (China, Japan, South Korea, Taiwan, Rest of East Asia). The Market Forecasts are Provided in Terms of Volume (TW).
Regional policy frameworks now embed gigawatt-scale targets in economic planning. China's 15th Five-Year Plan ties provincial GDP metrics to renewable roll-outs, ensuring political accountability for capacity gains. Japan's seventh Strategic Energy Plan finalized in 2024 raised the 2040 renewable electricity goal to 50% and switched to feed-in-premium auctions that flex with wholesale prices, reducing fiscal exposure while safeguarding developer cash flows. South Korea's RE3020 requires public institutions to source 35% of power from renewables by 2030, already catalyzing 18 utility-scale solar tenders in 2025. Taiwan legislated a USD 28 billion offshore wind and green hydrogen fund through 2030, monitored quarterly by the Bureau of Energy. Together these programs imply a regional carbon price floor near USD 45 per ton, rendering unabated coal uncompetitive before the decade's end.
Asia-Pacific solar and wind levelized costs fell 16% in 2024 as polysilicon oversupply, N-type cell efficiencies above 25%, and bifacial adoption near 70% drove module prices to USD 0.09 per watt. China's utility-scale PV averaged USD 27 per MWh in 2024, undercutting gas by 35%. Inner Mongolia wind auctions cleared at USD 31 per MWh in 2025 thanks to 6.5 MW turbines with 180-meter rotors. Offshore wind remains pricier, yet localized supply chains in Jeollanam-do aim for USD 55 per MWh by 2028 as Doosan Enerbility's 15 MW nacelles reach volume scale. Continuous cost compression widens the East Asia renewable energy market addressable base and encourages hybrid storage pairings that secure evening-peak premiums.
Solar curtailment in China hit 9.2% during Jan-Feb 2026 as 180 GW of 2025 additions outpaced transmission growth. Tibet dumped 17% of midday solar because a lone 3 GW line serves a 400 MW load. State Grid has earmarked CNY 650 billion for five new ultra-high-voltage corridors through 2027, yet typical build times run up to four years. Hokkaido's curtailment drop post-HVDC shows targeted links can resolve bottlenecks, but Korea still caps variable renewable share at 25% without co-located storage. Persistent congestion restrains near-term additions and trims the East Asia renewable energy market growth runway.
Other drivers and restraints analyzed in the detailed report include:
For complete list of drivers and restraints, kindly check the Table Of Contents.
Solar Energy commanded 53.1% of installed capacity in 2025. Continuous cost declines, desert mega-bases, and rooftop mandates cement its primacy, though polysilicon audits bifurcate supply chains. Ocean Energy's low 2025 base under 300 MW underpins its 43.4% CAGR, with South Korea's Sihwa barrage and Japan's Proteus turbine signaling commercial readiness.
Turbine scaling lifts wind contributions; 16 MW platforms now generate 80 GWh annually, doubling 2020 units. Pumped-storage hydro like China's 3.6 GW Fengning plant stabilizes variable output, while geothermal additions in Kyushu diversify Japan's mix. Concentrating solar and bioenergy stay niche as PV costs plunge below USD 0.10 per watt. Ocean technology pilot success could expand the East Asia renewable energy market frontier beyond traditional resources.
