LCOEはプロジェクトスクリーニングには有用だが、技術比較やエネルギー転換の総コスト評価には不適切である。本稿はLCOEの方法論的限界を指摘し、マクロ経済フレームワークを提案する。このフレームワークはエネルギーの実質コスト変化を国民所得に結び付け、転換コストを明示的に評価する。
English
LCOE is useful for project screening but unreliable for comparing technologies or assessing total transition costs. This paper critiques LCOE's methodological flaws and introduces a macroeconomic framework linking real energy cost changes to national income, making transition costs explicit.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもLCOEは再生可能エネルギー導入議論で多用されるが、本稿の指摘は日本のエネルギー政策(第6次エネルギー基本計画など)のコスト評価に重要な示唆を与える。マクロ経済フレームワークは、日本の転換コストを国民所得ベースで可視化する手法として応用可能。
In the global GX context
Globally, LCOE dominates renewable cost comparisons, but its limitations can mislead policy. This paper’s macroeconomic framework offers a more transparent, economy-wide approach, aligning with ISSB and TCFD calls for systemic risk assessment in transition finance.
👥 読者別の含意
🔬研究者:Provides a clear critique of LCOE methodology and an alternative framework that can be operationalized for empirical studies on transition costs.
🏢実務担当者:Helps energy analysts and corporate strategists understand why LCOE-based comparisons are misleading and how to think about economy-wide cost impacts.
🏛政策担当者:Offers a replicable framework for assessing national income effects of energy transition, supporting more robust cost-benefit analysis for decarbonisation policies.
📄 Abstract(原文)
While Levelised Cost of Electricity (LCOE) can be useful as a project‑level screening tool, this paper argues that it is not a reliable basis for comparing electricity generation technologies or assessing the wider cost of energy transition. Standard LCOE calculations embed inconsistent discount rates, overlook end‑use differences, omit key technologies such as nuclear from headline comparisons, and treat projected carbon prices as fixed inputs rather than uncertain policy variables. Individually and in combination, these methodological choices distort cost comparisons and risk misleading policy decisions. To address this, the report introduces a simple macroeconomic framework that links persistent changes in the real cost of energy to national income using a small number of observable variables, making the cost of transition explicit and testable under alternative scenarios. Together, these insights highlight the need to move beyond narrow generation metrics toward more transparent, economy-wide assessments of energy transition costs.
