電力向陽生

美國能源資訊署（U.S. Energy Information Administration，EIA）於最新短期能源展望報告中指出，美國電力需求增長正呈現更廣泛的地理分布，而新增需求將主要由太陽能發電滿足。

The U.S. Energy Information Administration (EIA) reported in its latest Short-Term Energy Outlook that electricity demand growth in the United States is becoming more geographically widespread, with new demand expected to be met primarily by solar generation.

EIA 表示，德州與美國中大西洋地區的經濟活動升溫與資料中心建設擴張，是近期電力需求成長的重要驅動因素。此外，本月 EIA 進一步上調中部與中西部地區的電力消費預測，主因是對資料中心擴張速度的預期提高，顯示 AI 與雲端基礎設施建設正逐步向內陸地區擴散，而非僅集中於傳統科技樞紐。

According to the agency, rising economic activity and data center expansion in Texas and the Mid-Atlantic have been key drivers of recent demand growth. EIA also raised its outlook for electricity consumption in the Central and Midwest regions, citing stronger expectations for data center development beyond traditional technology hubs.

太陽能成長動能最強，風電穩步擴張

EIA 指出，太陽能將持續成為美國成長最快的發電來源。該機構預測，2026 年太陽能發電量將成長 17%，2027 年再增長 23%；同期風力發電則預計分別成長 6% 與 7%。

Solar to Remain the Fastest-Growing Source

EIA projects that solar generation will increase by 17% in 2026 and by an additional 23% in 2027. Wind generation is expected to grow by 6% and 7%, respectively, over the same period.

依據預測數據，美國今年太陽能發電總量將達 3,410 億度（kWh），2027 年將升至 4,180 億度，高於 2025 年的 2,910 億度。顯示在聯邦與州層級政策支持、企業購電協議（PPA）以及科技產業低碳承諾的推動下，再生能源滲透率持續提升。

新增裝置容量大幅領先化石燃料

根據美國聯邦能源管制委員會（Federal Energy Regulatory Commission，FERC）最新能源基礎設施更新報告，去年 1 月至 11 月期間，美國新增太陽能裝置容量達 25.4 GW，顯著高於天然氣新增的約 4 GW 及風電新增的 5.5 GW。

Total U.S. solar generation is forecast to reach 341 billion kilowatt-hours (kWh) this year and 418 billion kWh in 2027, up from 291 billion kWh in 2025. These projections reflect continued policy support at federal and state levels, corporate power purchase agreements, and growing clean energy commitments from technology companies.

New Capacity Additions Outpace Fossil Fuels

Data from the Federal Energy Regulatory Commission (FERC) show that from January to November of last year, new solar capacity additions totaled 25.4 gigawatts (GW), significantly exceeding new natural gas capacity at approximately 4 GW and new wind at around 5.5 GW.

EIA 進一步指出，2026 至 2027 年間，約有 70 GW 的新太陽能發電容量預計上線，較 2025 年底的營運容量增加 49%。這意味著美國太陽能產業正處於加速擴張階段，其增量規模已遠超傳統化石燃料機組。

EIA further noted that nearly 70 GW of new solar capacity is scheduled to come online in 2026 and 2027, representing a 49% increase in operating solar capacity compared with the end of 2025. This underscores the accelerating expansion of the U.S. solar sector relative to conventional generation sources.

資料中心與能源轉型交織

Data Centers Reshape Power Planning

隨著人工智慧運算需求與雲端資料處理規模迅速擴大，資料中心用電正成為電力負載成長的核心變數。這種結構性需求成長，迫使能源規劃必須同步考量電網穩定性、儲能部署與區域輸電能力。

The rapid expansion of artificial intelligence and cloud computing infrastructure is emerging as a structural driver of electricity demand. As data center loads grow, energy planning must increasingly account for grid reliability, energy storage deployment, and regional transmission capacity.

整體而言，EIA 的最新預測顯示，美國電力需求與再生能源供給正進入同步擴張階段，而太陽能將在未來兩年成為承接新增電力需求的關鍵主力。

Overall, EIA’s latest outlook suggests that U.S. electricity demand growth and renewable supply expansion are entering a synchronized phase, with solar power positioned as the principal source meeting incremental demand over the next two years.
