本論文は、固定価格の再生可能エネルギーPPA（電力購入契約）の評価とリスク評価のための財務フレームワークを開発。風力・太陽光発電の主要なPPA設計のペイオフ構造を形式化し、公正な契約価格を導出。モンテカルロシミュレーションを用いた市場リスク評価手法と太陽光発電のための連続時間モデルを提案。イタリア電力市場の実証分析により、技術や契約構造ごとに価格とリスクプロファイルが大きく異なることを示す。
English
This paper develops a financial framework for the valuation and risk assessment of fixed-price renewable Power Purchase Agreements. It formalizes payoff structures of main PPA designs for wind and solar, derives fair prices, and proposes a Monte Carlo simulation-based risk methodology. Empirical analysis of the Italian electricity market shows significant variation in fair prices and risk profiles across technologies and contractual structures, highlighting the trade-off between downside protection and market participation. The framework provides practical tools for pricing and risk evaluation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、固定価格買取制度（FIT）の終了に伴い、再生可能エネルギーPPAの重要性が高まっている。本論文の評価フレームワークは、日本企業や電力会社がPPAの価格設定やリスク評価を行う際の実践的ツールを提供する。特に、太陽光と風力の技術別リスク分析は、日本の電源構成に応じたPPA設計に示唆を与える。
In the global GX context
Globally, renewable PPAs are crucial for corporate decarbonization and energy transition. This paper advances financial and risk assessment tools for non-standard PPA structures, applicable across markets. The empirical evidence from Italy offers comparative insights for other liberalized electricity markets.

📄 Abstract（原文）
Renewable Power Purchase Agreements have become increasingly important instruments for supporting the energy transition, as they offer revenue stability to renewable energy producers and price certainty to electricity consumers. This paper develops a financial framework for the valuation and risk assessment of fixed-price renewable PPAs. We formalize the payoff structures of the main PPA designs adopted in practice for wind and photovoltaic generation and derive fair contract prices based on financial valuation principles. We further propose a market risk-assessment methodology based on Monte Carlo simulation and introduce a parsimonious continuous-time model for solar irradiance suitable for financial applications. An empirical analysis of the Italian electricity market shows that fair prices and risk profiles vary substantially across technologies and contractual structures, highlighting the trade-off between downside protection and participation in favorable market outcomes. This framework provides practical tools for the pricing and risk evaluation of renewable PPAs.
