The Oki Island-Nishinoshima Substation – Hybrid Battery Energy Storage System is a 6,200kW energy storage project located in Nishinoshima Town, Shimane, Japan.

The electro-chemical battery energy storage project uses hybrid as its storage technology. The project was commissioned in 2015.

Description

The Oki Island-Nishinoshima Substation – Hybrid Battery Energy Storage System was developed by Mitsubishi Electric . The project is owned by The Chugoku Electric Power (100%).

The key applications of the project are renewable capacity firming and voltage support.

Contractors involved

GS Yuasa , Mitsubishi Electric, NGK Insulators and The Chugoku Electric Power have delivered the battery energy storage project.

Additional information

This demonstration project was selected under the “2014 Storage Battery Demonstration Project to Promote the Introduction of Renewable Energy on Isolated Islands” of the Ministry of Environment. Through the operation of the hybrid storage battery system, The Chugoku Electric Power Company expects to introduce renewables over 10 MW, the minimum demand of the Oki Islands, by adding up approximately 8 MW of new installations on the existing 3 MW, in the entire Oki Archipelago.
