フィンランドの公共オフィスビルにおける太陽光発電と蓄電池のハイブリッドシステムについて、周波数制御予備力（FCR-N）提供の経済性と環境影響を線形計画法で最適化し評価。FCR-N提供が蓄電池の経済的成立に必須であり、200kWh以上の容量で正味キャッシュフローが正になることを示した。また、FCR-N提供の環境影響をクレードル・トゥ・ゲート排出量で定量化し、2.29 g CO2e/kW/hという値を提示した。

This study optimizes a hybrid PV-BESS system in a Finnish public office building, showing that FCR-N provision is essential for BESS economic viability, with net-positive cash flows at capacities ≥200 kWh. It introduces a cradle-to-gate emission metric for FCR-N, finding 2.29 g CO2e/kW/h for a two-hour BESS under Nordic regulation, highlighting the role of ancillary services in renewable transition.

日本のGX文脈において
日本では、再生可能エネルギーの導入拡大に伴い、蓄電池の系統安定化への貢献が注目されている。本論文のFCR-N提供の経済性評価は、日本の需給調整市場や容量市場における蓄電池ビジネスの採算性検討に示唆を与える。また、環境影響の定量化手法は、日本の蓄電池導入におけるライフサイクル評価の参考となる。
In the global GX context
Globally, this paper contributes to the growing literature on the economic viability of BESS in ancillary service markets, which is critical for integrating variable renewables. The novel cradle-to-gate emission metric for grid balancing provides a basis for quantifying the environmental footprint of frequency regulation, relevant for markets like the UK's or Australia's.

📄 Abstract（原文）
This paper investigates the economic and environmental impacts of Frequency Containment Reserve (FCR-N) provision for a hybrid battery energy storage system (BESS) and solar photovoltaic (PV) installation in a public office building located in Finland. Various scenarios and capacities were optimized using linear programming. The results show that FCR-N provision was necessary for the economic viability of BESS. Notably, net-positive system-level cash flows were achieved with a BESS capacity of at least 200 kWh. Generally, BESS affected annual system costs noticeably more than PV did. Furthermore, a cradle-to-gate emission metric is introduced to quantify the environmental impact of FCR-N provision. This metric was found to be 2.29 g CO₂e/kW/h for a two-hour BESS under Nordic regulation. The findings confirm the central role ancillary services have in the economic viability of BESSs. They also provide a basis for quantifying the environmental impact of grid balancing within the renewable energy transition. ; ei tietoa saavutettavuudesta
