Tokyu Power Supply Fully Enters Battery Storage Station Business, Starting Operations in FY2026 – Contributing to Power Supply-Demand Stability and Effective Use of Renewable Energy

東急パワーサプライが蓄電所事業に本格参入 ２０２６年度に運転開始 ～電力需給の安定化および再生可能エネルギーの有効活用に貢献～

Tokyu Power Supply is entering the grid-scale battery storage business, with its first storage station in Omaezaki, Shizuoka starting operation in April 2026, followed by stations in Tsu, Mie (May) and Ota, Gunma (June). The company will also own storage and aggregate third-party storage, aiming to absorb surplus daytime solar and improve procurement economics for its retail business. Construction is by Sun Village; specific capacities are not given in the text.

  • Company: Tokyu Power Supply Co., Ltd. (HQ: Setagaya-ku, Tokyo; President: Kazuhide Miyo); release dated 14 April 2026.
  • Entering grid-scale storage business to expand "energy creation" and "energy storage".
  • First station: Omaezaki, Shizuoka (TPS Shizuoka Omaezaki 01 storage station), operation from April 2026.
  • Further stations: Tsu, Mie in May 2026; Ota, Gunma in June 2026 (planned).
  • Construction: Sun Village Co., Ltd.
  • Note: one charge/discharge cycle per day equals the daily usage of about 750 average households (per the overview; MW/MWh not stated in text).
  • Rationale: rapid solar growth causes daytime surplus; charging surplus and supplying at night raises CO2-free share over 24 hours and supports Japan's NDC (60% and 73% GHG cuts vs FY2013 in FY2035 and FY2040, submitted Feb 2025).
  • Will participate in aggregation business (bundling distributed resources like a VPP), contributing to renewables expansion and tight supply-demand situations, while expanding revenue.
  • Expected to improve procurement economics and renewable acceptance for its retail business, 10 years after liberalization.
  • Existing activities: supporting Tokyu Setagaya Line on 100% renewable power, local supply from Setagaya-ku Miura solar plant to bus stops, off-site PPA CO2-free power to Tokyu Group commercial facilities.
  • Project lead comment: will own grid storage and aggregate others' storage, moving from a pure power/gas retailer into multiple power business areas with a more resilient, diversified structure, and contribute long-term to renewable acceptance.

東急パワーサプライが蓄電所事業に本格参入 ２０２６年度に運転開始 ～電力需給の安定化および再生可能エネルギーの有効活用に貢献～

  • 株式会社東急パワーサプライ（本社：東京都世田谷区、社長：御代一秀）、２０２６年４月１４日発表。
  • 「創エネ」「蓄エネ」拡大を目指し系統用蓄電所事業に参入。
  • 第１号蓄電所：静岡県御前崎市（TPS静岡御前崎01蓄電所）、２０２６年４月より運転開始。
  • 同年５月に三重県津市、６月に群馬県太田市で順次運転開始予定。
  • 施工：株式会社サンヴィレッジ。
  • １日１サイクルの充放電で一般家庭約７５０世帯の１日の使用量に相当（MW・MWhは本文に記載なし）。
  • 背景：太陽光普及で日中の電力余剰が顕在化。余剰を充電し夜間に供給することでＣＯ２フリー電力のシェアを高め、ＮＤＣ（２０３５年度・２０４０年度に２０１３年度比６０％・７３％削減、２０２５年２月提出）にコミット。
  • アグリゲーション事業（分散型エネルギーリソースを束ねVPPのように機能）にも参画し、再エネ導入拡大・需給ひっ迫時に貢献しつつ収益拡大。
  • 電力自由化から１０年の小売事業で調達の経済性改善、再エネ受容量拡大を図る。
  • 既存の取組：東急世田谷線の再エネ１００％運行サポート、「世田谷区みうら太陽光発電所」由来電力のバス停留所等への供給、オフサイトＰＰＡでの東急グループ大規模商業施設へのＣＯ２フリー電力供給。
  • プロジェクト責任者：系統蓄電所の自社保有と他社保有分のアグリゲーションに取り組み、電力・ガス小売専業から複数の電力事業領域へ踏み出し、強靭化・多様化した事業構造で臨み、長く再エネ受容量拡大に貢献する。
