日本語
本論文は、ギリシャの電力市場（前日市場・需給調整市場）における蓄電池の収益を最大化する最適化モデルを用い、蓄電池導入拡大に伴う競争激化が市場価格や調達可能な調整エネルギー量に与える影響を分析する。得られた収益ストリームからMIRR（修正内部収益率）に基づく経済性評価を行い、異なる価格動向下での蓄電池投資の実現可能性を検討している。
English
Using an optimization model that maximizes storage revenues in Greece's Day-Ahead and Balancing Markets, this paper analyzes how rising storage penetration and competition reduce balancing prices and accessible balancing energy. It then applies a Modified Internal Rate of Return (MIRR) assessment to evaluate storage investment viability under different price dynamics.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
蓄電池投資の収益性評価は、再エネ大量導入下での系統安定化・調整力確保という日本のGX課題と共通する。ただし本論文はギリシャ市場制度に基づく分析であり、日本への直接的な示唆は限定的で、蓄電池事業の収益モデル設計の参考事例として位置づけられる。
In the global GX context
As global power systems integrate more renewables, storage economics and market design are central to the energy transition. This paper contributes empirical evidence from Greece's newly implemented storage market framework, offering a replicable MIRR-based methodology for assessing storage investment viability under competition—relevant to ISSB/transition-finance discussions on energy infrastructure.
👥 読者別の含意
🔬研究者:蓄電池の市場収益モデルと競争影響を定量化する手法（最適化＋MIRR）の実証例として参考になる。
🏢実務担当者:蓄電池事業の投資判断において、市場競争激化が収益に与える影響を考慮する必要性を示唆する。
🏛政策担当者:蓄電池普及に伴う調整市場価格の低下を踏まえ、投資インセンティブ設計や容量メカニズムの検討に資する。
📄 Abstract（原文）
Participation of energy storage systems in electricity markets is a rapidly growing research area, in response to increasing renewable energy penetration and evolving market designs. Greece has recently set in place the regulatory framework for storage participation in both the Day-Ahead and Balancing Markets. As interest in storage deployment increases, it is imperative for investors to be aware of the relevant potential revenues. This paper is based on the authors' optimization model which maximizes revenues from storage participation in the Day-Ahead and Balancing Markets, considering both capacity and energy products in upward and downward directions, in line with Greek market rules. Indicative results on past research from the authors highlight the role of the Balancing Market in storage-related investments, with a significant increase in annual revenues compared to participation only in DAM. However, such results have not considered the competition that will be introduced in case of increased storage installation in Greece. This paper considers the impact of increasing penetration of energy storage assets in market results, particularly with potential reductions in Balancing Market prices. Moreover, the paper examines a potential reduction in the amount of balancing energy that an examined storage asset will have access to due to increased competition. The resulting revenue streams are used to perform an economic assessment based on the Modified Internal Rate of Return (MIRR), enabling an evaluation of the economic viability of storage investments under different price dynamics.
