資料中心發電機：市場佔有率分析、產業趨勢與統計資料、成長預測（2026-2031 年）

預計到 2026 年，資料中心發電機市場價值將達到 79.2 億美元，從 2025 年的 75.7 億美元成長到 2031 年的 98.9 億美元。

預計從 2026 年到 2031 年，其複合年成長率將達到 4.56%。

這一穩步成長得益於超大規模設施的激增和新一輪人工智慧叢集的興起，它們正將機架密度推向兆瓦級，從根本上改變了備用電源的設計。儘管柴油機組仍佔據安裝基礎的大多數，但碳減排政策、燃料價格波動以及更嚴格的Tier 4排放法規正在加速人們對天然氣、氫氣和HVO平台的興趣。大缸徑引擎的供應鏈限制延長了交貨時間，促使營運商簽訂多年框架協議或改用從區域組裝中心出貨的模組化機組。同時，創紀錄的銅價推高了發電機製造成本，促使原始設備製造商（OEM）更加垂直整合，並在技術允許的情況下擴大鋁繞組的使用。競爭壓力正從單純的功率轉向更廣泛的因素，例如燃料柔軟性、排放規性以及提供預測性維護分析的數位化服務，以確保發電機的運作。

全球資料中心發電市場趨勢與洞察

快速建造超大規模和託管設施

如今，超大規模計劃的裝置容量通常超過100兆瓦，迫使營運商將數十個2.5兆瓦的機組聚合起來，建造N+2環網，以確保即使在斷電情況下也運作。 2024年，Google累計50億美元，將新加坡資料中心的容量擴大35%，相當於新增超過150兆瓦的備用電源。託管服務供應商也在進行類似的擴張，例如普林斯頓數位集團在其位於馬來西亞的150兆瓦園區部署了並聯開關設備，以最佳化負載削減流程。合約內容越來越涵蓋發電機供應、試運行和長期維護，從而降低了前置作業時間風險和價格波動。隨著對超大規模設施建設的需求不斷成長，原始設備製造商（OEM）正在加強其在東南亞和美國中西部的本地組裝基地，以解決物流瓶頸並利用國內採購激勵政策。

透過人工智慧工作負載提高機架功率密度

裝滿GPU的機架，每個GPU的功耗高達1兆瓦，正在考驗傳統發電機組的安全裕度，迫使其重新評估容量，甚至徹底更換。康明斯宣布，其電力系統業務在第一季的營收成長了19%，並將成長歸功於人工智慧資料中心訂單。業者要求更嚴格的電壓調節頻寬和小於10秒的動態反應時間，以保護數千個無法承受電壓驟降的互聯加速器。為了解決這個問題，發電機組正在採用更大的交流發電機、主動諧波濾波器和液冷迴路，以散發高位定子產生的熱量。韌體升級還實現了與飛輪式UPS緩衝器的即時同步，確保在電網發生故障時實現無縫切換。

柴油發電機碳排放法規

加州空氣資源委員會限制了非緊急運作時間並強制要求即時監測，迫使營運商安裝昂貴的選擇性催化還原（SCR）設備和顆粒物過濾煙囪。在歐盟，工業排放指令收緊了許可程序，對於嚴重依賴柴油的校園，核准最多會延遲14個月。遵守法規會增加生命週期擁有成本，因為廢氣後處理組件必須每15,000個運作小時更換一次。雖然一些校園已透過將備用發電機組遷移到監管較少的地區來應對，但這種策略與對延遲敏感的用戶需求相衝突，迫使原始設備製造商（OEM）創新研發更清潔的燃燒技術和混合動力解決方案。

細分市場分析

至2025年，柴油發電機將佔需求的81.25%，但隨著營運商對碳排放責任進行財務量化，其成長潛力已趨於平緩。 2028年更嚴格的配額最終確定後，預計資料中心柴油發電機市場規模將略有成長，之後趨於穩定。氫能和氫化植物油（HVO）平台雖然基數小規模，但得益於即時的兼容性和政府稅收優惠政策，正展現出強勁的成長勢頭。隨著1%混合燃料在歐洲天然氣管網的普及，氫能發電機在資料中心發電機市場的佔有率預計將穩步提升。

監管激勵措施進一步推動了這一趨勢。德國494號設施撥款5.5億歐元用於維修綠色備用電源，並鼓勵訂購可自動調節至甲烷-氫氣混合燃料的雙燃料引擎。同時，超大規模資料中心業者正在簽署可再生柴油採購協議，以確保2030年之前的價格可預測性。製造商則透過空中韌體更新來應對，根據燃料特性的變化重新校準噴射圖，從而延長引擎壽命並提供針對生物柴油污染的保固保護。儘管柴油因其能量密度和普遍可用性仍然十分重要，但替代燃料正在獲得創新動力。

由於需要數千個小規模邊緣站點來確保本地內容傳送，1MW 以下的機組仍然佔據主導地位。然而，隨著超大規模營運的不斷精簡，對 2MW 以上單一機組的需求正在加速成長。預計到 2031 年，資料中心發電機市場 2MW 以上的細分市場將以 13.78% 的複合年成長率成長，幾乎與長期以來在 1MW 以下細分市場佔據領先地位的機組持平。營運商青睞這些更大功率的機組，因為更少的引擎可以簡化燃料物流，減少備件庫存，並縮小面積——這對於沿海光纖登陸點附近的高成本地區來說至關重要。

原始設備製造商 (OEM) 正在透過引入配備工廠預裝配電盤和控制設備的模組化驗收測試間來解決供應鏈擁塞問題，將現場試運行時間縮短至 10 天以內。同時，租賃設備供應商也在擴展其 1-2 兆瓦功率範圍的產品組合，以填補交付缺口。合約通常包含在設備出貨後購買永久設備的選項；這些靈活的模式有助於保持資本預算的可預測性，並避免因託管合約中承諾在特定日期前交付機架而產生的逾期罰款。

資料中心發電機市場按產品類型（柴油、天然氣、氫/HVO相容型、其他）、容量（<1MW、1-2MW、>2MW）、等級（Tier I/II、Tier III、Tier IV）、資料中心類型（超大規模、企業級、主機）和地區進行細分。市場預測以美元計價。

區域分析

北美地區佔2025年總收入的40.55%，這主要得益於北維吉尼亞、達拉斯和鳳凰城等高密度資料中心走廊的強勁發展。目前，投資重點已從購買新土地轉向提高電力密度，營運商正用3.5兆瓦的Tier 4-Fital型號發電機替換老舊的2兆瓦柴油發電機，從而在不擴建牆體的情況下充分利用閒置頻段。聯邦政府對氫氣和沼氣生產的稅額扣抵也進一步推動了向低碳發電機的轉型。

亞太地區展現最強勁的成長潛力，預計2031年複合年成長率將達到10.42%。新加坡已解除資料中心許可的暫停發放限制（前提是效率提升），並正在推動五個總合300兆瓦的計劃計畫。印度的《數位個人資料保護法》正在刺激國內雲端運算建設，光是孟買一地就計畫新增700兆瓦的IT負荷。在日本，Softbank Corporation位於北海道的園區（300兆瓦）正在與水力發電電網對接，並配備雙燃料備用電源以應對地震造成的停電。同時，馬來西亞和印尼正透過向超大規模資料中心業者營運商提供土地贈款和可再生能源認證，成為具有成本主導的地區。歐洲在絕對值方面排名第三，但在永續性要求方面卻處於領先地位。阿姆斯特丹市政府透過限制柴油車運作時間和對年二氧化碳排放超過500噸的車輛課稅，鼓勵業者改用燃氣引擎和電池混合動力汽車。都柏林輸電能力的限制迫使開發商將目光轉向西班牙和葡萄牙，導致電力需求向南轉移。中東地區正充分利用其豐富的天然氣和太陽能資源：杜拜數位園區正在安裝燃氣發電機組，並配備吸收式製冷機，將廢熱用於區域供冷系統。非洲雖然仍處於起步階段，但已展現出巨大潛力，內羅畢和拉各斯正在部署配備400千伏安柴油發電機的微型模組化資料中心，以應對不穩定的電網。

第7章 市場機會與未來展望

The data center generator market size in 2026 is estimated at USD 7.92 billion, growing from 2025 value of USD 7.57 billion with 2031 projections showing USD 9.89 billion, growing at 4.56% CAGR over 2026-2031.

This steady climb is rooted in the surge of hyperscale facilities and the new wave of artificial-intelligence clusters that now push rack densities into the megawatt range, fundamentally transforming backup-power design. Diesel units still anchor most installations, but carbon-reduction policies, volatile fuel prices, and stricter Tier 4 rules accelerate interest in natural-gas, hydrogen, and HVO-ready platforms. Supply-chain shortages for large-bore engines lengthen delivery cycles, prompting operators to lock in multi-year framework agreements or pivot toward modular blocks shipped from regional assembly hubs. Meanwhile, copper prices at record highs squeeze alternator manufacturing costs, driving OEMs to intensify vertical-integration moves and to substitute aluminum windings where technical requirements allow. Competitive pressure is therefore shifting from pure horsepower to a broader mix of fuel flexibility, emissions compliance, and digital service offerings that guarantee a generator's readiness with predictive maintenance analytics.

Global Data Center Generator Market Trends and Insights

Surging Hyperscale and Colocation Build-out

Hyperscale projects now regularly exceed 100 MW, forcing operators to aggregate dozens of 2.5 MW units into N+2 rings that guarantee uptime during grid loss. In 2024, Google earmarked USD 5 billion to lift Singapore capacity by 35%, translating into more than 150 MW of incremental standby generation Colocation specialists mirror that scale, exemplified by a 150 MW campus under Princeton Digital Group in Malaysia designed with parallel switchgear lineups to streamline load-shed sequencing. Contract structures increasingly bundle genset supply, commissioning, and long-term service to curb lead-time risk and price volatility. As hyperscale pipelines swell, OEMs strengthen local assembly bases in Southeast Asia and the U.S. Midwest to reduce logistics bottlenecks and to align with domestic-content incentives.

Rising Rack-Power Densities from AI Workloads

GPU-rich racks that consume up to 1 MW each compress the safety margin of legacy generator fleets, prompting capacity re-rating or wholesale replacement. Cummins posted a 19% jump in Power Systems revenue in Q1-2025, attributing the rise to AI-driven data center orders . Operators now specify tighter voltage-regulation bands and dynamic-response times below 10 seconds to protect thousands of interconnected accelerators that cannot tolerate brownouts. Generator skids therefore integrate larger alternators, active harmonic filters, and liquid-cooling circuits that dissipate elevated stator heat. Firmware upgrades also enable real-time synchronization with flywheel UPS buffers, ensuring seamless transition when grid events occur.

Carbon-Emission Regulations Targeting Diesel Gensets

California's Air Resources Board limits non-emergency runtime and enforces real-time monitoring, compelling operators to fit costly SCR and particulate-filter stacks. In the European Union, the Industrial Emissions Directive intensifies permitting scrutiny, delaying approvals by up to 14 months for diesel-heavy campuses. Compliance lifts lifecycle ownership costs as exhaust-after-treatment parts must be replaced every 15,000 engine hours. Some campuses respond by relocating backup yards to less-regulated jurisdictions, yet that strategy collides with latency-sensitive user demands, keeping pressure on OEMs to innovate cleaner combustion or hybrid solutions.

Other drivers and restraints analyzed in the detailed report include:

1. Expansion of Edge Data Centers in Emerging Markets
2. Transition to Natural-Gas and HVO Gensets for Sustainability
3. Shift Toward Battery and Fuel-Cell Alternatives

Segment Analysis

Diesel sets anchored 81.25% of 2025 demand, yet their headroom is capped as operators quantify carbon liabilities in financial terms. The data center generator market size for diesel solutions is projected to expand marginally before plateauing post-2028 once stricter quotas lock in. Hydrogen and HVO-ready platforms, though starting from a small base, exhibit outlier growth, propelled by immediate drop-in compatibility and government tax credits. The data center generator market share for hydrogen-ready units is forecast to climb steadily as 1% blends become commonplace in European gas grids.

Regulatory incentives further tilt momentum. Germany's funding line 494 directs EUR 550 million toward green backup power retrofits, funneling orders toward dual-fuel engines that self-calibrate to methane-hydrogen blends. Simultaneously, hyperscalers sign offtake agreements for renewable diesel to lock price visibility through 2030. Manufacturers respond with over-the-air firmware updates that retune injection maps when fuel properties shift, prolonging engine life and protecting warranties against biodiesel contamination. Diesel therefore remains critical for its energy density and universal availability, but alternative fuels capture the innovation spotlight.

Less than 1 MW units retain dominance because thousands of small edge sites must guarantee local content delivery. However, hyperscale rationalization accelerates demand for single-block ratings beyond 2 MW. Greater than 2 MW slice of the data center generator market is forecast to compound at 13.78% annually, and by 2031 it will nearly equal the long-time less than 1 MW leader. Operators favor these larger frames because fewer engines simplify fuel logistics, reduce spares inventory, and shrink the real-estate footprint-an important consideration on high-cost plots near coastal fiber landings.

OEMs tackle supply-chain congestions with modular factory-acceptance testing booths that pre-wire switchgear and controllers so that field commissioning falls below 10 days. Rental-fleet providers simultaneously grow their 1-2 MW portfolio to bridge delivery gaps; contracts often include a purchase option once permanent gear ships. Such flex models keep capital budgets predictable and guard against late penalties in colocation contracts that promise rack readiness by preset dates.

Data Center Generator Market is Segmented by Product Type (Diesel, Natural Gas, Hydrogen and HVO-Ready, Other Product Types), Capacity (Less Than 1 MW, 1-2 MW, Greater Than 2 MW), Tier Type (Tier I and II, Tier III, Tier IV), Data Center Type (Hyperscale, Enterprise, Colocation), and Geography. The Market Forecasts are Provided in Terms of Value (USD).

Geography Analysis

North America claimed 40.55% of 2025 revenue on the strength of dense data center corridors in Northern Virginia, Dallas, and Phoenix. Investment now centers on power-density upgrades rather than new land acquisition; operators swap aging 2 MW diesels for 3.5 MW Tier 4-Final models to unlock white-space without expanding walls. Federal production tax credits for hydrogen and biogas further sweeten the switch to low-carbon gensets.

Asia-Pacific showcases the strongest momentum with a 10.42% CAGR through 2031. Singapore lifts its moratorium on data center permits in return for efficiency pledges, unlocking a pipeline of 300 MW across five projects. India's Digital Personal Data Protection Act fuels domestic cloud builds, with Mumbai alone planning 700 MW of fresh IT load. In Japan, SoftBank's 300 MW Hokkaido campus integrates hydro-backed grids but still specifies dual-fuel backup to counter seismic-related outages. Meanwhile, Malaysia and Indonesia emerge as cost-competitive hubs by offering land concessions and renewable-energy certificates tailored to hyperscalers. Europe ranks third in absolute value but leads in sustainability mandates. Amsterdam's municipality now caps diesel runtime and levies CO2 fees above 500 t/year, nudging operators toward gas engines and battery hybrids. Dublin's grid-capacity crunch pushes developers to Spain and Portugal, thereby redistributing generator demand southward. The Middle East leverages abundant natural gas and solar resources; Dubai's Digital Park installs gas-fired gensets with absorption chillers that recycle waste heat into district-cooling loops. Africa remains early-stage yet promising, with Nairobi and Lagos deploying micro-modular data centers backed by 400 kVA diesels to overcome unreliable grids.
