Notice of Start of Operation of Yasugi Battery Storage Station

安来蓄電所運転開始のお知らせ（安来蓄電所）

RENOVA announced that its 2MW Yasugi battery storage station in Yasugi City, Shimane Prefecture, began operating on April 17, 2026. The company has brought market-operation functions (bidding and charge/discharge dispatch) in-house to build operational know-how for larger projects such as its 90MW Kikugawa storage station. The project is a step toward RENOVA's mid-term plan target of 0.9GW of storage capacity by 2030.

  • RENOVA Inc. (HQ: Chuo-ku, Tokyo; President & CEO Yosuke Kiminami) announced on April 20, 2026 that the Yasugi Battery Storage Station (Yasugi City, Shimane Prefecture; capacity 2MW) started operation on April 17, 2026.
  • RENOVA sees cost competitiveness through scale as key amid many new entrants to Japan's battery market driven by renewable expansion.
  • Four major barriers to scaling storage: grid connection, procurement, operation, and finance; this project focuses on establishing optimal battery operation strategy.
  • RENOVA has in-housed the 'optimal operation function', directly handling bidding in power markets and charge/discharge commands.
  • Know-how and data from the 2MW project will support stable operation and revenue maximization of large projects, including the 90MW-class 'Kikugawa Nishimura storage station' / 'Kikugawa storage station (90MW)', described as among Japan's largest, under development.
  • Operation is described as an important step toward the mid-term plan goal of 0.9GW storage capacity by 2030.
  • 'Market-sale type' model: revenue earned by providing balancing capacity and supply capacity in markets such as the balancing market (需給調整市場) and capacity market, without relying on state price guarantees (e.g. FIT) or long-term fixed-price contracts with specific counterparties.
  • Mission: build green and self-sustaining energy systems to solve key social issues; contribute to grid stabilization and decarbonization.

安来蓄電所運転開始のお知らせ（安来蓄電所）

  • 株式会社レノバ（本社：東京都中央区、代表取締役社長CEO：木南陽介）は2026年4月20日、「安来蓄電所」（島根県安来市・設備容量2MW）が2026年4月17日付で運転を開始したと発表。
  • 国内蓄電池市場は再エネ導入拡大を背景に多様なプレイヤーが参入しており、競争力の鍵は「大規模化によるコスト競争力」と認識。
  • 蓄電事業の大規模化には「系統接続」「調達」「運用」「ファイナンス」の4つの壁があり、本蓄電所は最適な「蓄電池の運用戦略」確立を主眼とする。
  • 「最適運用機能」を内製化し、電力市場での応札や充放電指令等の業務を直接担う。
  • 2MWの本事業で運用知見とデータを蓄積し、90MW級の「菊川西村蓄電所」や国内最大級の「菊川蓄電所（90MW）」など大型プロジェクトへ展開。
  • 中期経営計画の「2030年までに蓄電事業の設備容量0.9GW」目標達成に向けた重要な一歩。
  • 「市場販売型」：FIT制度等の国の価格保証や特定相手との長期固定価格契約に頼らず、「需給調整市場」や「容量市場」で調整力・供給力を提供して収益を確保する事業形態。
  • ミッション「グリーンかつ自立可能なエネルギー・システムを構築し、枢要な社会的課題を解決する」のもと、電力系統の安定化と脱炭素社会実現に貢献。
