Financing models, energy diplomacy, and strategic dependency in nuclear power projects: A comparative analysis of Akkuyu and El Dabaa nuclear power plants
摘要
Nuclear power projects combine long construction periods, high capital intensity, contractual arrangements, and long-lived geopolitical relationships. This study compares the Akkuyu Nuclear Power Plant in Türkiye and the El Dabaa Nuclear Power Plant in Egypt to examine how financing architecture interacts with capital cost, ownership, debt exposure, operational control, and supplier dependence. The projects are treated as highly comparable rather than technically identical: both are four-unit Rosatom-supplied VVER-1200 projects with a gross capacity of 4800 MW, but Akkuyu uses the V-509 variant and El Dabaa the V-529 variant. The quantitative analysis uses a common net electricity-output basis of 35 TWh/yr. A standardized August-2026-real-USD scenario holds technical and operating assumptions constant and treats 8% for Akkuyu and 6% for El Dabaa as scenario discount rates rather than observed WACCs, yielding LCOEs of 6.30 and 5.37 cent/kWh. A second scenario makes public capital-cost proxies price-consistent: Akkuyu's USD 24.5 billion 2024 current-price estimate is normalized to USD 26.16 billion in August 2026 dollars, while El Dabaa's USD 28.75 billion agreement-era estimate is treated as a 2017-dollar proxy and normalized to USD 39.29 billion. The resulting LCOEs are 8.28 and 9.21 cent/kWh, respectively. This reversal shows that financing conditions cannot be interpreted independently of capital-cost level and price base. Akkuyu's tariff-LCOE comparison is reported only as an August 2026 base-date spread, while El Dabaa's sovereign loan is treated separately as a nominal debt-service obligation. Policy evaluation should jointly stress-test capital cost, discount rates, offtake terms, debt service, exchange-rate exposure, localization, and supplier resilience.
中文摘要
核电项目兼具建设周期长、资本密集度高、合同安排复杂以及地缘政治关系持久等特点。本研究比较土耳其阿库尤核电站与埃及埃尔达巴核电站，考察融资架构如何与资本成本、所有权、债务敞口、运营控制及供应商依赖相互作用。两个项目被视为高度可比而非技术完全相同：二者均为俄罗斯国家原子能公司供应的四机组VVER-1200项目，总装机容量4800 MW，但阿库尤采用V-509型，埃尔达巴采用V-529型。定量分析采用35 TWh/年的统一净发电量基准。标准化2026年8月实际美元情景保持技术与运行假设不变，并将阿库尤8%和埃尔达巴6%视为情景贴现率而非观测到的加权平均资本成本，得出平准化度电成本分别为6.30和5.37美分/千瓦时。第二情景使公共资本成本代理值价格一致：阿库尤245亿美元2024年现价估算值归一化为2026年8月美元的261.6亿美元，而埃尔达巴287.5亿美元协议期估算值被视为2017年美元代理值并归一化为392.9亿美元。由此得出的平准化度电成本分别为8.28和9.21美分/千瓦时。这一反转表明，融资条件不能脱离资本成本水平和价格基准来解读。阿库尤的电价与平准化度电成本比较仅作为2026年8月基准日的价差报告，而埃尔达巴的主权贷款则单独作为名义偿债义务处理。政策评估应联合对资本成本、贴现率、承购条款、偿债、汇率敞口、本地化及供应商韧性进行压力测试。
