本研究以 2019–2025 年台灣與國際燃氣複循環電廠（Advanced Combined Cycle, ACC）建設成本為研究主題，分析疫情後造價大幅上升的原因。研究蒐集國際資料（EIA、IEA、IHS Markit）與台電及民營電廠（IPP）之成本資訊，並結合營造物價指數及電力需求，建立跨年度比較架構。
研究結果指出，造價上漲為全球共同現象，主因包括：能源轉型推升燃氣機組需求、再生能源間歇性增加對調度型電力的依賴、AI 與資料中心用電激增造成燃機市場吃緊、OEM 產能有限導致價格上調與交期延長，以及疫情後原物料與施工成本全面上升。台電案造價特別偏高，則與其工程規範保守、現場施工比例高及流程複雜等因素相關。
本研究認為，台灣能源轉型需採多元策略：提前鎖定燃機排程、導入模組化施工、提升儲能併網能力，並重新評估核能在穩定供電中的角色。整體而言，燃氣電廠造價上升為能源轉型過渡期的結構性趨勢，台灣唯有整合燃氣、核能、再生能源與儲能，才能維持供電穩定與成本競爭力。

This study investigates the construction cost trends of Advanced Combined Cycle (ACC) of Combine Cycle Gas Turbine power plants in Taiwan and major international markets from 2019 to 2025, with particular focus on the significant cost escalation observed after the COVID-19 pandemic. Drawing on data from EIA, IEA, IHS Markit, as well as publicly available information on Taipower and Independent Power Producer (IPP) projects, this research incorporates construction cost indices, electricity demand data, and international EPC benchmarks to establish a multi-year comparative framework.
The results indicate that the rise in ACC construction costs is a global phenomenon driven by multiple structural factors: increasing reliance on dispatchable generation due to growing shares of intermittent renewable energy; surging electricity demand from AI and data-center development; tight global supply of gas turbines caused by accelerated energy transition; limited OEM manufacturing capacity leading to longer delivery times and higher prices; and post-pandemic inflation in materials, labor, and construction services. In Taiwan, Taipower’s projects display notably higher unit costs compared with IPP and international benchmarks, largely due to conservative engineering specifications, high on-site construction content, and complex administrative requirements.
This study concludes that Taiwan’s energy transition (2025–2035) requires a diversified strategy addressing system stability, supply chain constraints, and rising demand. Key recommendations include early reservation of gas turbine manufacturing slots, modernization of Taipower’s engineering standards, greater adoption of modularized construction, enhanced deployment of energy storage, and a pragmatic reassessment of nuclear energy as a stable, low-carbon baseload option. Overall, ACC cost escalation reflects structural changes in global energy transition, and Taiwan’s future energy security depends on integrating gas, nuclear, renewables, and storage in a balanced and resilient framework.
