本研究は、タイのコンケン大学が2040年までにカーボンニュートラルを達成するための戦略として、太陽光発電（PV）導入を評価。8,760時間の電力負荷データと空間適合性分析、時間別PVシミュレーションを用い、10～30MWpの容量における自家消費率、自給率、出力抑制率を分析。最適容量は19～22MWpとされ、バッテリーなしでScope 2排出量を26～30%削減可能。
English
This study assesses solar PV deployment as a flagship Scope 2 measure for Khon Kaen University's carbon neutrality target by 2040. Using 8,760-hour load data, spatial analysis, and hourly PV simulation, it evaluates self-consumption, self-sufficiency, and curtailment rates for 10-30 MWp capacities. The optimal range of 19-22 MWp achieves a self-consumption ratio of 98.9-99.7% and reduces Scope 2 emissions by 26-30% without battery storage.

日本のGX文脈において
日本の大学もカーボンニュートラル目標を掲げる中、本論文の負荷データとPVシミュレーションによる最適容量評価手法は、日本国内のキャンパスでも応用可能であり、Scope 2削減策として示唆に富む。特に自家消費率を最大化する設計は、FIT終了後の自家消費型太陽光の導入検討に参考となる。
In the global GX context
This paper provides a replicable methodology for universities worldwide to design cost-effective solar PV systems for carbon neutrality. It demonstrates how to balance self-consumption and grid interaction using hourly data, which is directly applicable to institutions under carbon disclosure frameworks (e.g., CDP, ISSB) that require verified Scope 2 reductions.

🏛政策担当者:Provides evidence that targeted PV deployment can significantly contribute to national carbon neutrality goals in the education sector.
📄 Abstract（原文）
The transition of universities toward carbon neutrality requires not only strategic planning but also a feasibility assessment. In the case of the energy sector, the largest GHG source in large higher-education institutions. This study integrates strategic planning analysis with technical evaluation for Khon Kaen University (KKU), which targets carbon neutrality by 2040 and positions solar photovoltaic (PV) deployment as the flagship Scope 2 measure within that pathway. Using 8,760-hour electricity load data, spatial suitability analysis, and hourly PV simulation, the study evaluates the self-consumption ratio (SCR), self-sufficiency ratio (SSR), and curtailment rate across PV capacities of 10–30 MWp, and quantifies the resulting direct GHG reduction and 2040 load-projection performance. Purchased electricity accounts for 60–65% of KKU's emissions, equivalent to a baseline of approximately 81,600 tCO2e/yr. The optimal capacity range of 19–22 MWp yields an SCR of 98.9–99.7%, an SSR of 26–30%, and a curtailment rate of 0.27–1.08%, achievable without battery storage. This range corresponds to a direct GHG reduction of approximately 13,300–15,300 tCO2e/yr, or approximately 26–30% of Scope 2 and 16–19% of total institutional emissions. Under a projected 2040 load scenario, the same capacity range remains technically valid, confirming it as a robust, no-regret near-term measure. These findings demonstrate a strategic balance among direct emissions reduction, load compatibility, and operational feasibility and can guide other Thai universities in linking emissions diagnostics to practical, evidence-based, and monitorable energy strategies.
