エクアドルの2003〜2024年の電力発電を対象に、設備容量と実効容量の乖離、燃料依存、GHG排出を診断した研究。IPCC 2006ガイドラインとAR5/AR6のGWP係数を用い、CO2・CH4・N2Oの年次系列を推計。非再生可能電源がCO2の大半を占める一方、非従来型再エネはCH4・N2Oに寄与する。水力偏重や燃料補助金の変動など構造的脆弱性が脱炭素シナリオの制約となることを示す。
English
A diagnostic study of Ecuador's electricity generation (2003–2024) examining structural vulnerabilities, fuel dependence, and GHG emissions. Using IPCC 2006 Guidelines and AR5/AR6 GWP factors, it estimates annual CO2, CH4, and N2O series. Non-renewable sources dominate CO2, while non-conventional renewables contribute notably to CH4 and N2O. Hydropower concentration, insufficient thermal backup, and fuel-subsidy volatility constrain decarbonization pathways.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業の直接の対象国ではないが、水力偏重・燃料補助金依存という構造的脆弱性は、再エネ比率拡大と電源多様化を進める日本の電力脱炭素戦略や、Scope 2排出量算定における電源構成の不確実性を考える上で示唆がある。
In the global GX context
Adds a Global South empirical case to the electricity-sector decarbonization literature, complementing TCFD/ISSB-aligned transition planning by quantifying how structural grid vulnerabilities (hydrology risk, subsidy volatility) shape credible emission-reduction pathways and national climate commitments.
👥 読者別の含意
🔬研究者:IPCCガイドラインに基づく発電部門のGHG推計手法と、電源構成の脆弱性が排出プロファイルに与える影響の実証例を提供する。
🏢実務担当者:新興国での電力調達やScope 2算定において、電源構成の変動と排出係数の不確実性をどう扱うかの参考になる。
🏛政策担当者:水力依存と燃料補助金の変動が脱炭素シナリオの実現可能性を左右する点を、電源多様化政策の設計に活かせる。
📄 Abstract（原文）
This research presents a comprehensive diagnosis of Ecuador’s electricity generation (2003–2024), focusing on structural vulnerabilities, fuel dependence, and Greenhouse Gas (GHG) emissions from electricity generation. The technological composition of the grid, including installed and effective capacity, as well as the share of fossil and organic fuels, is analyzed to construct a coherent analytical framework. GHGs (i.e., CO2, CH4, and N2O) are estimated from fuel consumption in Non-Conventional Renewable Energy (NCRE) and Non-Renewable Energy (NRE), in accordance with the 2006 IPCC Guidelines. Conversion to CO2 equivalent utilizes the AR5 GWP factors, in agreement with AR6. The results present annual series for each gas and their corresponding CO2 equivalents, showing that NREs dominate the CO2 profile, while NCREs contribute significantly to CH4 and N2O. Despite the expansion of installed capacity, a gap persists with effective capacity, reflecting the structural vulnerabilities of Ecuador’s electricity generation system, including exposure to hydrological variability (Kraftnōt, referring in this research to electricity shortages caused by reduced hydropower generation under adverse hydrological conditions), insufficient thermal backup, a high concentration of hydropower plants, fluctuating fossil fuel subsidies, and limited diversification. This manuscript provides a technical and quantitative basis using annual CO2, CH4, and N2O values and their CO2 equivalents to inform future decarbonization scenarios that strengthen NCRE integration within international climate commitments and a sustainable electricity transition.
