炭素制約下の電力系統で蓄電池（BESS）容量倍増の効果を経済負荷配分最適化で評価した概念実証研究。250tCO2/日の排出上限は排出を22%削減するが供給不足を招き、日次運用コストは£0.1Mから£2.1Mへ急増。BESS倍増は負荷軽減に全く寄与せず、可変再生可能エネルギー増強や動的充電設計なしでは座礁資産化すると示す。
English
A proof-of-concept economic dispatch model assesses doubling BESS capacity in a carbon-constrained grid across four 24-hour scenarios. A 250 tCO2/day cap cuts emissions 22% but causes severe supply shortfalls, raising daily operating costs from £0.1M to £2.1M. Doubling storage yields zero relief—the BESS stays unutilized—showing storage expansion without more renewables or dynamic charging becomes a stranded asset.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
再エネ大量導入と蓄電池投資を進める日本の電力系統計画・容量市場設計に対し、蓄電池単独増強の限界を示す警鐘となる。GX推進下での系統増強と電源構成の同時最適化の重要性を示唆。
In the global GX context
Speaks to global decarbonization planning where storage is often framed as a silver bullet; it cautions that carbon caps and storage mandates must be paired with renewable over-provisioning and flexible charging to avoid stranded assets and cost blowouts.

📄 Abstract（原文）
This paper presents a proof-of-concept economic dispatch optimisation model to evaluate the operational, economic, and environmental impacts of scaling Battery Energy Storage Systems (BESS) within a carbon-constrained power network. Four distinct scenarios are evaluated over a deterministic 24-hour horizon: Baseline, Flexible, Low-carbon, and Doubled-Storage (120 MWh). The simulation results reveal a profound systemic bottleneck: while enforcing a strict carbon emission cap of 250 tCO2/day successfully reduces environmental impacts by 22%, it triggers severe supply inadequacy. This causes unserved load penalties that escalate daily operating costs from £0.1M to £2.1M. Crucially, doubling the BESS capacity provides zero operational relief, with the storage system remaining completely unutilized and flatlined at its initial state-of-charge. This paper demonstrates that expanding energy storage capacity in isolation—without concurrent over-provisioning of variable renewable generation capacity or dynamic charging architectures—creates a stranded asset that cannot mitigate supply deficits or lower system costs. The findings offer critical cautionary insights for grid planners and policymakers targeting decarbonisation milestones.
