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~（津市の蓄電所）

Tokyu Power Supply is entering the grid-scale battery storage business, starting its first storage station in Omaezaki, Shizuoka in April 2026, followed by Tsu, Mie in May and Ota, Gunma in June. The company will also pursue aggregation of its own and third-party storage assets, aiming to absorb surplus daytime solar power and improve procurement economics for its retail business. Capacity figures are not stated in the text, apart from an equivalence of about 750 households' daily use per cycle.

Release date: April 14, 2026, by Tokyu Power Supply Co., Ltd. (HQ: Setagaya-ku, Tokyo; President: Kazuhide Miyo; established October 2015)
Entering grid-scale storage business to expand 'energy creation' and 'energy storage'
First storage station in Omaezaki City, Shizuoka, operating from April 2026 (photo labelled 'TPS Shizuoka Omaezaki 01 storage station')
Further stations planned: Tsu City, Mie in May 2026; Ota City, Gunma in June 2026
Construction: Sun Village Co., Ltd.
One daily charge/discharge cycle equals roughly the daily use of about 750 ordinary households
Rationale: daytime solar surplus growing; charge surplus solar and supply at night to raise CO2-free share around the clock and support NDC commitment
Will also join aggregation business (bundling distributed resources like a VPP), contributing during supply tightness and expanding revenue; expected to improve procurement economics and renewable intake in retail business, ten years after liberalisation
Existing activities: 100% renewable power for Tokyu Setagaya Line, local consumption of 'Setagaya-ku Miura Solar Power Plant' electricity at bus stops, offsite PPA CO2-free supply to Tokyu Group commercial facilities
Project lead quote: company will own grid storage and aggregate others' assets, moving beyond pure electricity/gas retail into multiple power business areas with a more resilient, diversified structure, and contribute long-term to expanding renewable intake
Appendix: Japan's 2035/2040 NDC (submitted Feb 2025) targets 60% and 73% GHG cuts vs FY2013 in FY2035 and FY2040

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
背景：太陽光普及で日中の電力余剰が顕在化。余剰を充電し夜間供給等に回し、24時間のCO2フリー電力シェアを高めNDCにコミット
