- Nihon Chikudenchi (Chiyoda-ku, Tokyo) and Remix Point are jointly developing grid-scale storage plants (系統用蓄電所) at 7 sites nationwide.
- Fourth site: NC Makurazaki Sakuradai-higashi-cho storage plant (NC枕崎市桜山東町蓄電所), Makurazaki City, Kagoshima Prefecture, began receiving power on November 4.
- Rated output 1988 kW; rated capacity 8146 kWh.
- Battery: CATL (China); power conditioner (PCS): TMEIC.
- Plans to proceed with procedures to enter three electricity markets; entry to the balancing (需給調整) market is planned for around March 2027.
- Sites that have now begun receiving power: Tamana (Kumamoto Prefecture), Sendai City, Kama City (Fukuoka Prefecture), and Makurazaki City (Kagoshima Prefecture).
- Remaining three sites expected to begin receiving power: Kainan City (Wakayama Prefecture) in November 2026; Ibigawa Town (Gifu Prefecture) in December 2026; Nagano City in March 2027.
- NC Kuchiharu storage plant (NC口春蓄電所) in Kama City began operating for the balancing market on October 20: rated output 1975 kW, rated capacity 8146 kWh; CATL batteries and TMEIC PCS; aggregator is Digital Grid (デジタルグリッド).
- Remix Point acquired development land for 'Ena Iwamura 3 storage plant (provisional name)' in Ena City, Gifu Prefecture, its second self-owned high-voltage grid storage project in the prefecture. Planned: construction start around April 2027, power receipt late July 2027, balancing market entry around autumn 2027.
- Remix Point targets 48 high-voltage grid storage plants developed by the fiscal year ending March 2029, of which 25 to be self-owned. With the Ena land, self-owned projects including those in development total 12, reaching 48% progress against the self-owned target.
- Expected monthly sales of about 15 million yen per operating plant.
- Nihon Chikudenchi installed batteries on October 21 at two plants under development: NC Izumo Kunitomi-cho storage plant (Izumo City, Shimane Prefecture), designed and built by Kando (Shinjuku-ku, Tokyo); NC Minamiaizu Tajima-cho storage plant (Minamiaizu Town, Fukushima Prefecture), built by Craftia (クラフティア).

- 定格出力1988kW、定格容量8146kWh。
- 蓄電池：CATL製、パワーコンディショナー（PCS）：TMEIC（ティーマイク）製。
- 電力3市場への参入に向けた手続きを進める計画。需給調整市場への参入は2027年3月頃を予定。
- 受電済みは、熊本県玉名市、仙台市、福岡県嘉麻市、鹿児島県枕崎市の4カ所。
- 残り3カ所の受電開始見込み：和歌山県海南市が2026年11月、岐阜県揖斐川町が同年12月、長野市が2027年3月。
- 嘉麻市の「NC口春蓄電所」は10月20日から需給調整市場向けの運用を開始。定格出力1975kW、定格容量8146kWh。CATL製蓄電池とTMEIC製PCS。アグリゲーターはデジタルグリッド。
- リミックスポイントは岐阜県恵那市で「恵那岩村3蓄電所（仮称）」の開発用地を取得（県内2カ所目の自社保有高圧系統用蓄電所）。2027年4月頃着工、同年7月下旬受電開始、同年秋頃に需給調整市場へ参入を予定。
- 2029年3月期までに高圧系統用蓄電所48カ所の開発を目標、うち25カ所を自社保有する計画。恵那市の用地取得後、開発段階を含む自社保有案件は合計12カ所、目標に対する進捗率は48％。
- 稼働済み施設1カ所あたりの月間見込売上高は約1500万円を想定。
