日本語
スペインの原子力廃止時期延期が電力卸価格、再生可能エネルギー収益性、CO2排出に与える影響を分析。静的評価では価格と排出削減効果があるが、投資反応を考慮すると再生可能エネルギー投資を抑制し、長期的には価格上昇や排出増加につながる可能性を指摘。
English
This paper simulates the consequences of postponing nuclear retirement in Spain. It finds that while static benefits include lower prices and emissions, the dynamic effect undermines renewables investment due to reduced captured prices and increased curtailment, potentially leading to higher prices and emissions.

📄 Abstract（原文）
As Spain approaches the first scheduled nuclear retirements—most notably, Almaraz in 2027—the debate over the implications of delaying the nuclear phase-out has reopened. This paper uses detailed simulations of the Iberian electricity market to assess the consequences of postponing Almaraz’s closure on wholesale electricity prices, renewable and storage profitability, and power sector $$\hbox {CO}_2$$ emissions. We test the robustness of our findings to alternative investment targets, electricity demand paths, and gas marginal costs. We caution against a purely static assessment: while extending Almaraz, holding everything else equal, lowers prices and emissions by displacing gas, it also depresses renewables’ captured prices and increases curtailment, weakening incentives to invest in renewables and storage. If the investment response is large enough, a delayed nuclear phase-out may ultimately lead to higher prices and higher emissions.
