商用發電機：市場佔有率分析、產業趨勢與統計、成長預測（2026-2031 年）

據 Mordor Intelligence 稱，商用發電機市場預計將從 2025 年的 132.6 億美元和 2026 年的 143.8 億美元成長到 2031 年的 212 億美元，2026 年至 2031 年的複合年成長率為 8.07%。

本報告按燃料類型（柴油、天然氣、雙燃料和混合動力、其他）、額定功率（小於 75 kVA、75 kVA 及以上）、應用（備用電源、主電源/持續電源、其他）、終端用戶行業（商業建築、資料中心、其他）和地區（北美、歐洲、亞太、南美、中東和非洲）細分。市場預測以美元計價。

全球商用發電機市場趨勢與洞察

超大規模和邊緣資料中心的激增

PJM和ERCOT併網的平均等待時間約為八年，這促使營運商選擇在本地部署約10-12吉瓦的電力，而不是等待新的輸電基礎設施建設。在印度，資料中心的裝置容量正從2025年第二季的1.4吉瓦成長，並計畫在2030年達到4-10吉瓦，這得益於對新建超大規模資料中心業者400億美元的投資。 Atlas Energy斥資8.4億美元訂購1.4吉瓦的CaterpillarCG260-16和G3520天然氣發電機組，這清楚地表明，印度正在進行大規模、兆瓦級的「表後」電力採購，旨在解決電網瓶頸問題。

美國陽光地帶和歐盟快速發展的商業房地產正面臨電網限制。

預計到2025年，ERCOT的併網申請等候名單將達到226吉瓦，其中資料中心約佔待處理申請的四分之三。電網升級預計需要7到10年才能完成。奧斯汀、達拉斯、鳳凰城和坦帕等城市的開發商正在新建項目中安裝主發電機，而德國的辦公大樓則正在安裝持續運作的發電機，以應對太陽能和風能發電量減少的時期（稱為「Dunkelfraute」）。

商用電池價格暴跌

預計到 2025 年，磷酸鋰鐵鋰電池組的平均價格將降至每千瓦時 98 美元，比前一年下降 31%，到 2028 年將進一步降至每千瓦時 72 美元。目前，資料中心在斷電後的前 30 分鐘使用電池供電，而將發電機用於更長的斷電，從而減少 15-25% 的柴油消耗。

細分市場分析

預計到2025年，天然氣將以11.4%的複合年成長率成長，而柴油則佔商業發電市場的63.1%。推動這一轉變的原因是因為營運商希望避免Tier 4-Final後後處理系統相關的成本。Caterpillar與Atlas Energy簽訂的1.4吉瓦合約凸顯了這項轉型，而氫燃料混合引擎則為長期脫碳提供了一條潛在途徑。然而，液化天然氣指數的波動以及預計2027年的價格上漲，使得買家的燃料避險策略變得複雜。

柴油在快速啟動備用電源應用中仍然發揮著至關重要的作用，尤其是在天然氣管道接入受限的醫院和其他生命安全設施中。供應商透過提供模組化選擇性催化還原（SCR）套件來降低合規成本，這些套件可確保與生物柴油相容。此外，針對印尼和奈及利亞等地區通訊基地台最佳化的柴油-電池混合動力系統整合了自動負載追蹤功能，從而提高了引擎效率，最大限度地減少了怠速排放氣體，並延長了維護週期。

預計容量超過 750 kVA 的發電機組將以 10.1% 的複合年成長率成長，這主要得益於需要 N+1 冗餘的多兆瓦資料中心設施的需求。 Atlas Energy 迄今為止最大的 4.5 MW訂單訂單表明，市場對可擴展至 100 MW 的貨櫃式模組的需求正在成長。

預計到2025年，75-750千伏安中等容量發電機組將佔據49.7%的市場佔有率，繼續保持其銷售領先地位。此細分市場主要面向辦公園區、飯店和診所等場所，這些場所越來越需要遵守類似最低能源效率標準（MEES）的更嚴格的能源效率標準。同時，75千伏安以下的可攜式發電機組面臨來自電池供電替代方案的競爭。然而，隨著5G網路在非洲農村地區的擴展，由於電網運轉率維持在65%左右，20-50千瓦的發電機組仍有需求。

區域分析

預計到2025年，亞太地區將佔據商用發電機市場45.2%的佔有率，成為最大市場。這項成長主要得益於印度伺服器叢集的擴張，而印度伺服器叢集的擴張又受到沿岸地區AWS服務中斷的影響，以及超大規模資料中心業者資料中心400億美元的資本投資。這推動了那格浦爾和齋浦爾等二線城市的需求。此外，中國原始設備製造商（OEM）正在擴大其在中端市場的佔有率。在東南亞，5G網路正在快速擴張，由於電網擴建成本有時高達每公里5萬美元，30千瓦至250千瓦功率範圍的發電機訂單持續成長。

預計北美將呈現最高成長率，到2031年複合年成長率將達到9.1%。陽光地帶的電網限制正在推動對主用發電機組的強勁需求。例如，ERCOT（德州電力可靠性委員會）226吉瓦的專案待建清單以及鳳凰城12%的年負載成長凸顯了結構性供不應求，促使人工智慧晶圓廠和半導體製造廠部署兆瓦級天然氣發電廠。在加拿大，聯邦政府的獎勵正在加速氫能發電的維修；而在墨西哥，一項200億美元的近岸外包舉措正在蒙特雷工業園區創造對1000千伏安發電機組的需求。

在歐洲，如何平衡可再生能源的高普及率與「日落電力短缺」（Dunkelfraute）的風險，是亟待解決的問題。在德國，辦公大樓正在將燃氣引擎整合到建築規模的微電網中。在英國，業主們正根據「最低能源效率標準（MEES）」進行維修，這些標準通常包括備用發電機，以支援暖通空調系統的電氣化，而無需對電網進行擴容。斯堪的納維亞半島的礦場正在試驗使用100%氫動力裝置，而巴黎和米蘭的噪音法規已將低噪音座艙罩列為標準配備。

第7章 市場機會與未來展望

According to Mordor Intelligence, the commercial genset market is expected to grow from USD 13.26 billion in 2025 and USD 14.38 billion in 2026 to USD 21.20 billion by 2031, with a CAGR of 8.07% during the period from 2026 to 2031.

This report is Segmented by Fuel Type (Diesel, Natural Gas, Dual-Fuel and Hybrid, and Others), Power Rating (Below 75 KVA, and More), Application (Standby Power, Prime/Continuous Power, and More), End-User Industry (Commercial Buildings, Data Centers, and More), Geography (North America, Europe, Asia-Pacific, South America, and Middle East and Africa). Market Forecasts are Provided in Value (USD).

Global Commercial Genset Market Trends and Insights

Surge in Hyperscale & Edge Data-Centers

Queue delays at PJM and ERCOT average around eight years, leading operators to secure an estimated 10-12 GW of onsite generation rather than waiting for new transmission infrastructure. In India, the installed data center power capacity increased from 1.4 GW in Q2 2025, with a target of reaching 4-10 GW by 2030, supported by USD 40 billion in new hyperscaler investments. Atlas Energy's USD 840 million order for 1.4 GW of Caterpillar CG260-16 and G3520 natural gas units underscores substantial multi-megawatt behind-the-meter procurement aimed at addressing grid constraints.

Fast-Rising Grid-Constrained Commercial Real-Estate in the US Sun Belt & EU

ERCOT's interconnection queue is projected to reach 226 GW by 2025, with data centers accounting for approximately three-quarters of the backlog. Transmission upgrades are expected to take seven to ten years to complete. Developers in cities such as Austin, Dallas, Phoenix, and Tampa are incorporating prime-power gensets into new constructions, while German offices are installing continuous-duty machines to manage periods of reduced solar and wind energy generation, referred to as Dunkelflaute.

Rapid Fall in Commercial-Scale Battery Prices

Average lithium-iron-phosphate pack pricing decreased by 31% year-over-year to USD 98 per kWh in 2025 and is projected to decline further to USD 72 per kWh by 2028. Data centers now utilize batteries for the initial 30 minutes of outages, reserving gensets for prolonged events and reducing diesel consumption by 15-25%.

Other drivers and restraints analyzed in the detailed report include:

1. Diesel-to-Gas Switch Driven by Tier 4-Final & Euro Stage V Norms
2. Telecom 5G Densification in APAC & Africa
3. Stricter Urban Noise Ordinances on Standby Units

Segment Analysis

Natural gas is expected to grow at a compound annual growth rate (CAGR) of 11.4% by 2025, in contrast to diesel's 63.1% share of the commercial genset market. This shift is driven by operators aiming to avoid the expenses associated with Tier 4-Final after-treatment systems. Caterpillar's 1.4 GW Atlas Energy agreement underscores this transition, while hydrogen-blending engines offer a potential route for long-term decarbonization. However, fluctuating LNG indices and the anticipated price tightening in 2027 complicate fuel-hedging strategies for buyers.

Diesel continues to play a critical role in rapid-start standby applications, particularly in hospitals and other life-safety facilities where gas pipeline access is limited. Vendors are addressing compliance costs by offering modular selective catalytic reduction (SCR) kits and ensuring compatibility with bio-diesel. Additionally, hybrid diesel-battery systems, tailored for telecom sites in regions such as Indonesia and Nigeria, incorporate automated load-tracking to enhance engine efficiency, minimize idle emissions, and extend maintenance intervals.

Generator sets above 750 kVA are projected to grow at a CAGR of 10.1%, driven by the demand from multimegawatt data center facilities requiring N+1 redundancy. Atlas Energy's record order for 4.5 MW modules highlights the increasing preference for containerized blocks that can scale up to 100 MW farms.

The mid-range segment of 75-750 kVA is expected to maintain its position as the volume leader, accounting for 49.7% of the market share by 2025. This segment primarily caters to office parks, hotels, and clinics, which are increasingly required to comply with stricter efficiency mandates similar to MEES. Meanwhile, portable units below 75 kVA face competition from battery alternatives. However, rural African 5G network expansions continue to specify 20-50 kW gensets due to grid uptime remaining at approximately 65%.

Geography Analysis

Asia-Pacific is projected to hold the largest share of the commercial genset market, accounting for 45.2% in 2025. The growth is driven by India's server-farm expansion, influenced by AWS outages in the Gulf and a USD 40 billion hyperscaler capital expenditure, which is increasing demand in Tier-II cities such as Nagpur and Jaipur. Additionally, Chinese OEMs are gaining traction in mid-tier segments. In Southeast Asia, 5G network expansions, where grid extension costs can reach USD 50,000 per kilometer, are sustaining orders for gensets in the 30 kW-250 kW range.

North America is expected to record the fastest compound annual growth rate (CAGR) at 9.1% through 2031. Grid constraints in the Sun Belt region are driving high demand for prime-duty gensets. For instance, ERCOT's 226 GW project queue and Phoenix's 12% annual load growth highlight structural undersupply, fueling the deployment of multi-megawatt natural gas stations for AI fabs and chip manufacturing plants. In Canada, federal incentives are promoting hydrogen-ready retrofits, while Mexico's USD 20 billion nearshoring initiatives are channeling demand for 1,000 kVA gensets in Monterrey's industrial parks.

Europe is managing its high renewable energy adoption alongside Dunkelflaute risks. In Germany, office buildings are incorporating gas engines into building-scale microgrids. In the United Kingdom, landlords are addressing Minimum Energy Efficiency Standards (MEES) upgrades, which often include backup gensets to support HVAC electrification without requiring grid reinforcement. Nordic mines pilot 100% hydrogen units, and acoustic rules in Paris and Milan make low-noise canopies standard accessories.
