Rokkasho Village Wind Farm – BESS, Japan

By Carmen

The Rokkasho Village Wind Farm – BESS is a 34,000kW energy storage project located in Rokkasho, Aomori, Japan.

The electro-chemical battery energy storage project uses sodium based as its storage technology. The project was commissioned in 2008.

Description

The Rokkasho Village Wind Farm – BESS was developed by Japan Wind Development.

The key applications of the project are electric supply reserve capacity – spinning, renewable capacity firming and renewable energy time shift.

Contractors involved

Japan Wind Development and NGK Insulators have delivered the battery energy storage project.

Additional information

The project was commissioned in 2008. The batteries provide greater wind integration for electricity produced at night during periods of low demand, subsequently sold during the day and times of higher demand. The batteries can also be used to provide spinning reserve and frequency response. To protect them from corrosive salty air in the area, they are kept in suitable housing and consist of 17 sets of 2 MW battery units. They are monitored from a single control centre at the site, using smart grid monitoring and controls provided by Yokogawa Electric Corporation.
